CONOR FITZPATRICK PORTFOLIO 2016
About Me My name is Conor Fitzpatrick. I am a second year Product Design Technology student at Loughborough University looking for a third year placement. I am a tenacious person who enjoys a challenge, learning new skills and working with others. I am highly motivated and passionate about creating innovative solutions to design problems.

Adjustable Spine Corrector
Brief Redesign client’s exisƟng ‘Spine Corrector’ to add mechanism for adjustability in arc height and length to accommodate her taller clients who struggle with some exercises in order to avoid using crude modificaƟons.

The client wanted the style to be in keeping with her exisƟng equipment so number 2 was chosen.

Modelling Stage and Feedback
The client said that if someone sat on the corner of the step with no locking mechanism, it would liŌ up and Ɵp over which could cause injury.
Developed Mechanism for Adjustment

2 To stop the possibility of the step Ɵpping I re-designed the mechanism to include a hook. 1 uses ‘L’ bracket aluminium as it may make the step lighter but wood makes adjusƟng the ASC a more pleasant experience for my client so 2 was chosen.

Electric Bike Dock (Design Week)
Brief Design a product which supports domesƟc solar PV systems and solves a real life challenge. It should lead to beƩer use of solar energy and have a high value aestheƟc. Any technology must be immediately available.
Solution I designed a charging dock where someone can charge their electric bicycle over night from a baƩery charged by solar power. It can also be used to convert their bicycle to an exercise bike which, when used, charges the bike through a dynamo.
Research The E-bike has a 22V 10.75 Amp hour baƩery. The baƩery will charge fully over a period of 3.58 hours with its 3 Amp 19.2 Volt charging cable: E-Bike charging Ɵme = (Amp hours / Current) = (10.75 / 3) = 3.58 hours A baƩery, charged during the day, charges the bicycle at night when the photovoltaic cells are not powered by the sun. The baƩery transfers its charge passively when it is connected. Dock baƩery charging Ɵme= (Amp hours / Current) = (22 / 3) = 7.33 hours The user can reduce energy consumpƟon by using the exercise dynamo. The dynamo can produce 100W so in one hour the E-Bike baƩery can be charged by 27.9%.

Bike 11Ah

The dock baƩery needs to be twice the size of the baƩery it is charging so that when the bike is plugged in the charge of the dock baƩery flows to the bike baƩery and will only stop passively flowing when they reach the same charge. If the same size is used they would stop when they are both half full.
3.58 hours
User commutes to and from work on their electric bicycle while photovoltaic cells charge the dock battery.
They dock the rear wheel on the RANGE charging dock when they get home.
They connect the dock battery to the bike battery charging port which charges in roughly 3.6 hours.
Dock can also double as an exercise bike converter which charges the bicycle using a dynamo.

PLACE ‘PROJECT’ AT THE OPPOSITE TOP CORNER TO YOUR DRAWING HAND SO YOUR ARM DOES NOT AFFECT THE IMAGE
POSITION ‘PROJECT’ SO THAT YOUR PAGE LINES UP WITH THE GUIDES ON THE APP
YOU CAN NOW PROJECT ANY IMAGE OR SKETCHING TUTORIAL VIDEO ONTO YOUR PAPER. TWISTING THE DIAL WILL INCREASE/ DECREASE THE OPACITY OF THE PROJECTED IMAGE

Modelling I decided to put two holes through the base of the widget so that two separately manufactured aluminium rods could be used to secure the widget to the headphones band.
Story Board
The wire on Chloe’s headphones o en gets tangled and it makes it difficult to unwind.
She receives a free cable dy for registering her headphones online. It secures using an elas c strap.
Now she can quickly wrap the cable up and store the headphones away without the cable becoming tangled.

Electronics and C Programming
Black Line Following Robot This car uses two pairs of infrared emiƩers and detectors connected to four stepper motors by a logic circuit to drive and steer. The car was built from Lego and supports the circuit board, stepper motors, gears and wheels. Turn right: right infrared receiver = logic 1 (over black line), leŌ infrared receiver = logic 0 (over white surface). Turn leŌ: leŌ infrared receiver = logic 1 (over black line), right infrared receiver = logic 0 (over white surface).
Programmable Seven Segment Name Display Using the LC Technology FPGA Development board , switch and a seven segment display the circuit is programmed to display each leƩer of the name. When the debounced switch is pressed the leƩer advances to spell the name and then repeats. The code and circuit are flexible to make adding more seven segment displays easier.
Accelerometer Spirit Level Using the 18F45K20 microcontroller and an accelerometer the circuit can be used to measure the angle of Ɵlt of a surface. When flat the screen displays the arrow in the centre and as the box is Ɵlted the arrow rises towards the highest side emulaƟng a spirit level bubble.
