PRODUCT DESIGN The School of Industrial Design is engaged in education and research in product design, user experience design, and service and system design. With the rapidly changing technological, social, business and environmental landscapes, the discipline of Industrial Design has moved on from being primarily focused on aesthetics and styling to holistic user and customer experience design, and sustainability. While the school pursues the traditional issues of aesthetics and styling without any dilution in academic inputs, it actively engages with the emerging trends and paradigms of design with strategic design thinking, systems thinking, theories of user experience,

and environmental and ecological sustainability. The School continually strives to stay relevant for the business, society and governance through necessary improvements in curriculum, facilities, educational paradigms, and professional networking. The school currently offers Under Graduate and Post Graduate programmes in Product Design. The students can specialize in an area of their interest in the later semesters in their programme. The final semester in the UG and PG programmes is assigned for sponsored projects with a view to develop the readiness of students for leading the design initiatives in business, industry, and social sectors.

ABOUT ME I believe in being genuine, humble and a dependable one who sets high standards and achieves targets in a planned and a focused way. Ever since my childhood I had this habbit of sketching things and opening them apart to see whats inside. This lighted the fire of doing something where it involves studying old things and making new things. When I came across Product design, i found it pretty catchy and satisfying as to what i really wanted to do. Everyday in Product design is a new challenge and challenging the existing and taking every problem as an opportunity to find the solution is something which i learnt over my time studying different aspects UNITEDWORLD INSTITUTE OF DESIGN

of product design. The forms, aesthetics and the design of the products as well as the experience of using it are something I personally enjoy working on among so many aspects of product design.

MY MENTOR Prof. Vikram Panchal is an industrial designer by profession and currently a faculty member at Unitedworld Institute of Design.

UNITEDWORLD INSTITUTE OF DESIGN

School bells is from the Northern School Supply Company catalogue, published in 1913. These are the famous Bowlden bells.

School bells in India initially started to be a metal plate and a malet which is still in practice in village schools and other government schools.

1970s The Bells are still in use til date depending on the infrastructure of the school and school standards.

1960s

2000s These are the present electric gong bells that are present in most of the schools that are operated by a press of a button.

BRIEF HISTORY OF SCHOOL BELLS Past: School bells were first used in the 1800s. The bells would be hand held. Teachers would stand outside and ring the bell to bring the students inside. Students would have to be within earshot of the bell. Tardiness would result in punishments. Present: Modern school bells are electronic. Many bells are synchronized to make sure they are on time. Most bells ring at the beginning and at the end of the day, and in between class periods. Class lessons are altered by the time period of the class. Some classes do not have bells and are stopped by the teacher.

THE SCHOOL BELL The ringing of a school bell is a signal that tells a schoolâ&#x20AC;&#x2122;s students when it is time to go to class in the morning or afternoon and when it is time to change classes during the day as well as when students are dismissed from school. Typically the first bell tells the students that it is time to report to class and the bell that occurs shortly after that means that the students are late. There may also be a warning bell between the first bell and the late bell. In some schools it may take the form of a physical bell, usually electrically operated. In other schools it may be a tone, siren, electronic bell sound, a series of chimes, or music played over an intercom. Most schools where people who require sign language more than

hearing go to use hand signals.

WHY NEED A SCHOOL BELL ? To mark the beginning of the school day, the start and end of periods, and the end of every day. Bells are an easy way to let students know when their class starts if they don’t have a way to get the time. It will also reduce lateness, because if we have a two minute bell before every class, people will realize that they need to get to their class quickly or else they’ll be late. Without bells, students constantly need to check the time to see when they need to be at their next class. For example, if a student was early for school, and sitting by their locker reading a book or doing homework, class could start without them noticing, because there is no bell to tell them class has started, and they could be late for class. Without

bells, teachers could accidentally keep their class going for too long, therefore making students late for their next class. Having bells can improve students promptness and in turn, their academic success.

Respecting Punctuality When you transition from school into the workforce, it is evident that “time” plays an extremely important role in our careers. Deadlines, meetings, and operation hours, to name a few, all make up the average working day. Teaching children to respect the importance of being “on time” while still at school can make the transition much smoother. Being punctual also relies on the individual being prepared and organized. It is a known fact that when you are running late, you are most likely to forget something, thus punctuality also teaches kids time management and organization skills.

NEW PRODUCT DEVELOPMENT

HRIDAY MISTRY - UG PRODUCT DESIGN - GRADUATION PROJECT 2018

If you ask most bosses, punctuality is considered an incredibly valuable asset in a potential employee. Teaching children to respect being on time helps creates a generation of reliable, prepared men and women of the future. Reduced Disruption To Classes A typical school day, which sometimes varies from school to school, is run in segmented time blocks, which dictate how long classes and breaks are scheduled for. The lack of notification as to when classes and breaks are to start and finish allows for a lax in the schedule, meaning that some classes and/or breaks can be cut short. Both lunch breaks and class time lengths are important both for the students and teachers. Teachers require enough time to effectively teach all designated content whilst assisting students, whereas students require that time to effectively absorb, practice and retain that information. Cutting classes short can lead to consequences such: • Poor attention spans • Lack of information retention • Missed lessons and crucial information • Minimized time for the teacher to answer questions and UNITEDWORLD INSTITUTE OF DESIGN

misunderstandings that students may have to help them fully understand the content. Thus it is extremely important to the teaching and learning quality that a consistent lesson and break time schedule is in place within a school. Emergency School Bell Procedures School bell systems, nowadays are often used for more than just signaling the beginning and end of a class or break. In the event of a fire or lock-down, different bell sequences can be sounded to warn teachers and students of a possible emergency. In an emergency, communication is crucial, thus this method of emergency notification, is excellent to protect the safety and wellbeing of both staff and students. There’s nothing like hearing that 3:00pm sound to finish the day.

DECODING THE SCHOOL BELL An electric bell is a mechanical bell that functions by means of an electromagnet. When an electric current is applied, it produces a repetitive buzzing or clanging sound. Electric bells have been widely used at railroad crossings, in telephones, fire and burglar alarms, as school bells, doorbells, and alarms in industrial plants, since the late 1800s, but they are now being widely replaced with electronic sounders. It consists of coils of insulated wire wound round iron rods. When an electric current flows through the coils, the rods became magnetic and attract a piece of iron attached to a clapper. The clapper hits the bell and makes it ring.

NEW PRODUCT DEVELOPMENT

HRIDAY MISTRY - UG PRODUCT DESIGN - GRADUATION PROJECT 2018

UNITEDWORLD INSTITUTE OF DESIGN

HOW IT WORKS? To understand the operations of an electric bell, you should understand what an electromagnet is. An electromagnet works as a standard magnet (generating magnetic fields) but only with an electrical influence. When the power generation to an electromagnet stops, the production of the magnetic field also stops. The image below shows the internal mechanism of an electric bell. An electric source powers the electromagnet used in an electric bell. The switch which you press to sound an electric bell acts as the circuit breaker or the switch which completes the circuit. When the switch is pressed, the circuit loop is complete which causes current

to flow through the circuit. The arm which strikes the gong is connected to a spring at one end and an iron ball at the other end. This is called a clapper or a striker. The arm is attached to an iron strip which is attracted to the electromagnet when the circuit is complete and current is flowing through it. This is because the magnetic field created by the electromagnet attracts the iron strip towards it when the circuit is complete. At its rest position the clapper is held away from the gong on account of the spring attached to its arm. This is an anchored arm. Now that you have an understanding of the important parts in an electric bell, the step by step process of the working

of the electric bell is described below •The switch is pressed and current flows through the circuit •The electromagnet is powered and generates a magnetic field that attracts the iron strip towards it •The striker strikes the gong (bell) •When the striking arm strikes the gong, the contact is broken and current stops flowing through the circuit •This causes the electromagnet to lose its magnetic field •The connected spring arm returns the striker to its original rest position •The contact is restored and current flows through the circuit (provided the main switch is still pressed) •The process is repeated from the beginning.

ENVIRONMENT WITH RESPECT TO WORKING OF THE SCHOOL BELLS Considering the systems available in average schools these days, I visited one of such schools in which they had a simple electric bell system automated to the schools everyday schedule. It rings the bells mounted on each ends of the corridors. Not many changes can be made or customizability features available in the system. It needs to be rescheduled during the examination days and no special alert or patterns of rings available for special occasions like emergencies etc.

EXISTING PRODUCT PHOTOGRAPHY When I visited one of the such schools, I got a clear view of the system there, I could have a detail conversation with the person incharge of the bell system and the public address system of the school. I also got to click some pictures there. Observing the product well there, the usability and the environment around the product and also the basic ergonomics of the product with respect to its display viewing angle, the operational buttons and the height at which it was placed all play an important role. Also the Public address system amplifiers by which every speaker in the class is connected. Its placement and area around it, and how the person operates it.

USER SURVEY Thus, I did a quick user survey to know the views of people related to this system and are directly or indirectly affected by the school bells. Also to get a deeper understanding on the current systems of bells being used on an average and what are the difficulties faced by the users. Their views on improving the current bell also helped me to add on features and functions in my product and also lead me include things I didnâ&#x20AC;&#x2122;t even consider before. After analysing the complete survey it was easier for me to extract a good hypothesis from which I could derive my final brief of the project.

The Users that were surveyed were students, teachers and the parents on the students in school from different schools from different cities like Bangalore, Mumbai, Ahmedabad, Nasik, etc.

ISSUES WITH CURRENT ELECTRIC SCHOOL BELLS The user survey conducted gave me a lot of insights on the issues with the current electric school bells. It helped me to jot down and note specific problems faced by the users in a detailed manner. The issues with current bells in the schools are listed below. 1. Since most of the bells are not automated and run on human operation they tend to ring on late or before from the actual scheduled time. 2. Some people also find the current bell to be irritating, boring and monotonously same everytime. They find the sound of the bell annoying. 3. In schools that have pre-scheduled bells, they interrupt at times of exams, workshops, or other events. Schedules UNITEDWORLD INSTITUTE OF DESIGN

are disturbed. 4. Some classes fail to hear the bells clearly as the bell is pretty far, especially when the class door is closed. 5. During loss of power supply the bells go silent and the whole schedule is disrupted. 6. There is no difference in the periodic bell and emergency bells or lunch break bells or school start bells or end bells or prayer bells.

SCOPE OF IMPROVEMENTS The user survey opened a huge scope for improvements that can be made and the features that can be added. Referring to the issues based on the user survey there is vast possibilities for making a better and a useful product.

HYPOTHESIS Making a detailed note of the issues faced by the users from the survey, opened a lot of scope for improvements in the product that can be designed. Synthesizing the problems and the features that can be added to make the product better than ever before, a detailed hypothesis was made which in-turn helps to make the concept more clearer and define the final brief. The bell sound can be less irritating and be rather pleasing to the ears. It should be automated and should ring precisely ring on time. Different tones to indicate different purposes be it periodic, lunch break, start or end of the day, emergency situations. the notifications can also be given a personal touch by UNITEDWORLD INSTITUTE OF DESIGN

having human voice overs announcing the end of the class, breaks, etc. It can also be controlled by a phone or an Artificial intelligence. The functioning of the system should not be affected by the loss of power supply so may be it could have its own power backup.

THE CONCEPT We have the public address system in school, amplifiers and speakers. Usually the schools use for announcements and other activities for public addressing. The device will automate the amplifiers, it can automatically power on the amplifiers and plays the audio files which has to be played. So by this we can automate everything from regular notifications to prayers, assemblies, national anthem and instead of that boring electric bells that ring after every period. We can go for any other tunes or melodies and voice narration like for example, “it’s time for a first hour” or, “its time for your second period” or, “time for your lunch break similarly. There are the features like we can conduct a T-radio. If the schools subscribes for this

option the school will get a chance to implement a radio system in the school. This program can be used into building the communication skills of students in various schools. It can have a remote teaching system for schools for remote villages. So basically by automating the public address systems in the school we can achieve so many features. Also as a fire safety systems of the school. When the fire alarm goes on like the alarm comes in every block but the latest fire detection systems have something called as zonal addressing. So in-order to avoid panic situations, the public address system will clearly identify that from which point actually the fire happened and in that

particular block it is going to announce that like the evacuation plan will be announced and other blocks it will give announcement like “don’t panic until you get the real human voice directions”. So this is what TOLLER will do and this is all the possibilities. The settings to this device and those things that can be done from a web application or a phone application, so naturally it will be connected to the Internet. But Internet is not needed for the functioning of the device. If only some specific message has to be conveyed or some change in the settings it needs to be connected to the Internet. Otherwise the device can go by its own.

BUILDING THE ENGINEERING CAD After making the surface CAD, Its not yet over. A whole new phase of the development process starts now. Depending on the arrangements of internal components and giving material thickness to the surface CAD, all the internal detailing and fitments of the internal components are to be made. So a proper plan was made as to where and how the ribs and the bosses will be placed.

BUILDING THE INTERNAL ARCHITECTURE Building the internal architecture is whole another study and experience. Calculating the number of bosses and their specifications according to the proportions. How the top shell and the bottom shell will accommodate the internal components to form the complete product. I got to learn to take the product to the last stage of designing it. From here on we can send the final CAD for prototyping so that we can get accurate judgement on how the actual product is going to be.

HOW IT WORKS? The Meembit Toller is connected to the existing Public Address system of the schools. It is directly connected to the amplifier and the amplifier gets the power supply from toller. So what exactly toller does is it controls the amplifier by its own. Everything that scheduled and fed in toller will be automatically initiated and played on the exact time it is supposed to. The school bells, notifications, prayers, assemblies, breaks and start and end of school as well as periods are all programmed or customizable using the touch display of toller. Also you can control it using the mobile app as it can be connected to toller. The admin or the headof the school can pass on some important announcement from his phone itself.

Toller initiated the amplifier and the speakers play the tones or instructions provided by toller in each class simutaneously.
