cise being clumsy.3. Long, becoming part of the thumb atrophy and insensitivity4. When a lot of work can exacerbate5. Cup or catch and fine manipulation tasks that require paper clumsy.6. Fingers are hot.7. In the morning and wake up stiff hands or spasm.8. Often drop stuff.9. Costs power fist gripe10. On the night of 2 to 3 hours after deeper sleep because of the pain you wake up and awake.

•A good tool design strategy should apply these princi-ples(1)that handles the pressure of the palm of your hand to

avoid using the handle to the proper length of the han-dle as shown and avoided.

(2)Proper grip diameter , and given the grip on the sur-face of the friction is minimized

(3)Tool reduces the untitled .

(4)40 - 150 Hz vibration should be minimized to the ex-tent , especially .

(7) wrist posture be a tool to bring down a natural wrist posture to avoid a tool to be used.

(8 ) If the gloves protect the hands , or to maintain the temperature , if necessary , to enable dif-ferent size gloves should ensure Gloves should not constrict the blood circulation , and without sin should fit your hand properly . Hand grip strength of a 20- 30% armor reduces .

Finding a doctor

① Also known as carpal tunnel syndrome, carpal tunnel syndrome and wrist in the carpal bone that does not feature the original than would have occurred if the state will remain for some time.② Carpal tunnel syndrome, carpal tunnel, or wrist blood vessel walls of the clean mothayeo not turn it more As the carpal tunnel causes a thick covering③ The median nerve caused by swelling of the wrist ligaments pressed to surrounding muscles to function more and thus are discarded do not run into force on the wrist. If this situation per-sists, carpal tunnel syndrome will be.

● Product design: limitations① When worn on the wrist, the product is not a burden as much as possible of the wear.② Wear something that itself is a burden on the human body.③ Lighter than heavy, but it is good to design flexible products.

Create a product's ingredients to make the three alterna-tives.

3. Conclusion

3-1 Cap stone design do results

- performance product

The main configuration of this product, do as a result, as shown in Figure 20. largely comes down to three The first is an easy-to-use plaster, a variant of the appearance of the user's wrist to create a customized frame. And the second is that the wrist as much as possible, the herd can move back and forth less shop off the rollers is not only possible to use a 360-degree rotating circular roller. And the third is set in this wrist AIDS, skin, wrists, hostility to as much as possible to reduce the environmentally-friendly and cosy covered the top of the sheet.

3.Conclusion

● Future improvements☞ Products produced there went through trial and error a few times. When you try to create a cheaper price in terms of the effect in terms of the effect is extremely modest, by maximizing product price is not expensive if you try to create the material commercially difficult. It is to con-sider only the functional aspects of the issue looked handsome. In the end the material called plaster, effective at the same price, but consider-ing this aspect too was not a satisfactory results. Some of the more portable materials used in the human body, wondering how to improve the ma-terial to be produced, and shall study.

I felt looking at the wrist to create a secondary organization of the wrist causing the disease and increase of the disease, such as the ankles, too. Therefore, the burden of the wrist is designed as a fleet on the ankle this product to reduce the burden of creating a product that is a good idea and seems to be the product.
