ACTUAL PRODUCT PROTOTYPE

INTRODUCTION

Hanging clothes is a daily activity.Becomes a problem when it is taking a long time to

complete.The user could not collect all the clothes quickly

when heavy rain is approaching.

PROBLEM STATEMENT

The designed of the conventional hanger has required user to perform few actions to hang and collect cloths. As the cloths increases, the required action need to repeat many times which consume lot time to complete the work

Able to hang clothes easily.Time saving when collecting clothes.

Able to collect clothes with single hand.

BENEFITS OR IMPACT IF PROBLEM IS SOLVED

The strength of the hanger must able to support the weight of wet clothes.

Manufacturing process has to be same with the existing method.

The overall size of the hanger is same with the conventional.The cost of the new product for 5 dozens units must less than

RM 100.Types of clothes must be acceptable as in conventional

hanger.

ENGINEERING CONTRADICTION

Parameter involved:Improving parameter: Quantity of substance Worsening parameter: Loss in time

IF I INCREASE THE NUMBER OF HANGER, THEN MORE CLOTHES CAN BE HUNG AND DRIED,BUT IT TAKES LONGER TIME TO HANG THE

CLOTHES.

Suggested Inventive Principles:

#35 Parameter changes#38 Strong oxidants#18 Mechanical vibration/ oscillation#16 Partial or excessive action

CONTRADICTION MATRIX

Change an object’s physical state (e.g. to a gas, liquid or solid)

Change the plastic hanger’s degree of flexibilityThough is a great principle solution BUT!!!Boundary Condition restrict change of the

material and manufacturing of the plastic hanger.

#35 PARAMETER CHANGES

PHYSICAL CONTRADICTION

#9  Prior counter-action #10 Preliminary action #11 Beforehand cushioning #15 Dynamization #16 Partial or excessive action

#19 Periodic action #20 Continuity of useful action #34 Discarding and recovering #37 Thermal expansion

SEPARATION IN TIME

If an object (process) id rigid or inflexible, make it movable or adaptive.

It is a potential solution. Also suggested from TESE specifically the S-Curve

and Trend.

#15 DYNAMIZATION

Proposed Solution

Removed the base frame of the

hanger

Divide the hanger frame into middle part and frame arm

with a join(Frame arm movable)

• Insert spring under the frame• Spring constant, K must be

high enough to hold the weight of the frame and the weight of the cloth hung.

• But, is must be elastic so that user can compress with light force.

Add spring to the frame
