BRAINSTORM

Jam now only need to take a industrial mobile and the smart helmet to go to the underground mine.

This helps him to have contacts with the crew above the mine conveniently.

The oﬀ-color materials are used. when temperature/humidity is beyond security value, the earphones, the audible& visible alarms, will give warnings.

when gas density is over the standard, the earphones, audible &visible alarms, give warnings. Meanwhile, the hidden mask can be turned over to protect him.

SKETCHING The sketches provide more detailed informa�on about the solu�on� The miner light is installed through the slot Mul�-layers of the masks have the eﬀect of gas defence The connec�ng of ear bones headphones The sensor circuit is embedded in the back head of the helmet The temperature and humidity-sensi�ve and oﬀ-color materials, as a part of indicator of temperature and humidity.

It is like a stereo-anima�on formed by the vasomotor movement at the posi�on of “ 寸 ” , “关” and “尺” under doctors' ﬁngers. There are 27 pulse conditions in Tradi�onal Chinese Medicine, and we can divide it into 8 feelings, depth, strength, amplitude size, waveform, deﬁciency and excess, frequency, rhythm, and length , of the pulse. Every pulse condi�on among the �� arteries and veins can be seen as the sub-space of the above eight feelings.

SKETCHING

STORYBOARD

�ouise is a re�red woman who is di��y now,but the rela�ves are too busy to accompany her.

Finally, she goes through suﬀerings to arrive at the hospital, but she must to wait in line.

When she has a pulse-taking, the long term journey inﬂuences the diagnosis results.

The serious result aggravates her state of the illness.

Since she bought the House-check, she takes an e�amina�on by herself every week .

�ouise sends the condi�on a�er e�amina�on to her private doctor, swi� and convenient.

The private doctor checks physical condi�on & original pulse waveform through APP.

Through recupera�ng, she recovers well.

3D MODELING Design Descrip�on This is a home health checking equipment. According to the principles of the pulse-taking and the pulse waveform received by the infrared detec�on, the health status can be analy�ed.

The ﬂexible material makes the device �t all kinds of hand pa�erns. Users will feel more comfortable.

��rare� tra��mi��re�ei�i�� t�be when the heart beats once, the blood will carry more red blood cells to absorb the infrared ray.

MANUFACTURING

Course | Experimental Technique Training ,Grade | 98

This course requires me to design a PCB board with infrared pulse detec�on func�on and complete the whole process of making it.

After class, I developed it into this house-hold device, and reduced the scale of the circuit board in which I transformed the pin type element into patch type. Now, the pulse condition can be detected using the ﬁnger. The waveform can be seen when connecting the oscilloscope. However, the examinations of sub-health, organs, and tumor status are not achieved. By consulting the literature, I am sure these conclusions can be got through.

PROCESS

�/ Draw the schema�c diagram �/ Design PC� by �l�um Designer 3/ Heat Transfer Print 4/ Corrode copper clad laminate 5/ Drill with bench drill 6/ Weld components 7/ Debug 8/ Design the second version of circuit board to reduced the scale in which transformed the pin type element into patch type

Wheelchair user journey. Acting the role of the user in realistic scenarios can forge a deep sense of empathy and highlight challenges, presenting opportunities that canbe met by design. - Universal Methods of Design

Prototypes for Highlighting Issue - Sound

I can’t hear. Because it’s a crowded place. Social aspect is really important. People forget you are there. Because you are not in their eye line.

- Vision

My husband and I were looking at the view. He completely forgot that he is 1 miter taller than me. Our area is entirely different. And he went down to my height, said, ”Yes, it is just a wall.”

Social Barriers

- Attention - Dystopia

Stares, stares, everywhere. People just can't get over our differences sometimes, so going out in public is always akin to feeling like an animal at the zoo.

- Attention - Utopia

I enjoy the attention. Wheelchair is one of my coats. I want to dress elegantly.

Prototypes for Highlighting Issue - Mobility

- Man or Superman? Do I sound weird when I say I'm going for a walk?

The thing I want is always on the top shelf. Itâ&#x20AC;&#x2122;s hard to do housework such as using the vacuum cleaner, doing work underneath the table, cooking and taking food from the oven.

People always think we're in crisis mode or need help if they see us alone.

- Mobility vs Stability

- Customized

Yes, increasing the mobility is important. But stability is the most important thing.

Vacuum cushion which fits for various body sizes

- Interaction

Inflatable arms, it looks comfortable and soft, rather than metal and hard. Itâ&#x20AC;&#x2122;s like the hug of Baymax.

Practical Issue

What Is Important for Designing a Wheelchair?

“You use the wheelchair too much.” “No, I only use the wheelchair whenever I need it.” Wheelchair for us is like a durable coat you would wear for many years.
