6. The problem definition

• In the external environment outside the home, dehydrated and carry is uncomfort-able. Drying the umbrella and ensuring the drying space is not easy. Dry rust occurs in the umbrella. And hygiene problems arise by placing left. And to improve it.

Not spill the rainwater

7. Question investigation

1. What do you use an umbrella?

3 stage umbrellalong umbrelladisposable umbrellaetc

① 3 stage umbrella – 12 ② long umbrella– 10③ Disposable umbrella – 14 ④ etc- 8

resultShould be able to accommodate all the umbrellas in the distribution of various types of umbrellas

8. Question investigation

2. How do I keep the indoor?① Use a vinly cover – 25 ② Umbrella through use – 8③ neglect – 8 ④ etc - 3

use a vinly cover

umbrella through use

neglect

etc

resultThe waste is due to the use of vinyl cover.

9. Question investigation

3. What is inconvinient keep an umbrella?

worry about theftwater leaksbreakageetc

① worry about theft – 10 ② water leaks – 28③ breakage – 4 ④ etc - 2

resultThe water must not spill.

10. Source data collection and analysisCustomer's needs Interpreted needs1.I hope that is dried out the water buried below the umbrella.

You can dry the water.

2. I hope, the treatment of dry water is easy. The disposal of dry water is easy.

3. I hope that is durable. Very durable.

4. I hope, the water was not flying every-where.

Water not scattered everywhere.

5. I hope, the handle's length is varied ac-cording to the kind of umbrella.

The handle's length depends on what kind of umbrella.

6. I hope, the prices are lower. Price is cheap.

7.I hope, failure is not better. Failure is not better.

8. I hope, I could feel comfortable when hold onto it.

Easy to get a grip.

9. I hope, this material doesn't rust. No rust.

10. I hope that is no substance when pressed stiff.

No substance when pressed stiff.

11. I hope to harmless materials in human bodies.

It is harmless materials the body’s.

14. Relative importance of the design variables

• Function and perfor-mance

• Quality • Reliability• Safety

• Size• Product cost

• Weight• Government standard• Environmental problem

• maintenance standard• esthetic • appointed date of pay-

ment

Essential requirements

Highly desired requirements

Desired requirements

Almost irrelevant requirements

15. Prioritize design specifications (1)

1. Function and performance - Umbrella is not impaired, drainage is easy2. Effectiveness - Not out waste, it is possible to remove the mois-ture.3. Weight - Should not fall when dehydration by increasing the weight.4. Reliability - So that the difference between similar products and meet the customers' needs and design the price and fea-tures.5. Product cost - existing good + (10000 ~ 20000)

16. Prioritize design specifications (2)

6. Safety - designed so umbrella is not damaged7. Durability - The strong design.8. Size - Makes for an average size of umbrella9. Environmental problem - Should not have come out crap.

17. Sketch (1)

advantage : It is possible to reliably remove the moisture.

disadvantage : Sometimes stick to secure the handle does not match fit.

explanation : Put into an umbrella handle on the fixed rod. Fix the end of an umbrella on a dolrimpan. De-hydration to an umbrella by rota-tion.

17. Sketch (2)

advantage : Can be easily dried and saves time.

disadvantage : There is a risk of damage to the um-brella.

explanation : Water to wrapped to fit the corners of the table is dried by flowing under the entrance of the tube

17. Sketch (3)

advantage :Effect to secure the umbrella space & Effect of drying

disadvantage : Attached to the spill by friction of rubber & Doubt the size of an umbrella.

explanation : Moisture absorption of an umbrella to attach a rubber. An umbrella in and out. Dehydra-tion to an umbrella

17. Sketch (4)

advantage : Can be easily drying through a rotation.

disadvantage : Can't have sev-eral at once.

explanation : Umbrellas are at-tached through a hole drilled in the barrel. Pull the wire back into the umbrella. Remove the water by rotation.

17. Sketch (5)

advantage : Via the bent absorb-ing roller passage, it is possible to remove a slice moisture um-brella

Disadvantage : It is not possible to remove the moisture of-multiple of umbrella at a time. It is also possi-ble through the passage, the break-down comes into umbrella

Explanation : You can remove the moisture, along capable of remov-ing the moisture absorption pas-sage

• That is part of the entrance rubber materials in order to squeeze the water.

• Body part is using stainless steel in order not to rusted by water.

• Install a water tube in or-der to easily get water.

• The use of steel materials in order to secure the plate in the bottom.
