Extendable Clothes Hanger with Multi-Joint Link for Adjustable Width
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional clothing hangers lack the ability to extend in both directions to accommodate various clothing sizes and maintain clothing tautness effectively.
Innovation Solution
A clothing hanger design featuring a vertical frame, support frame, moving bar, multi-joint link, and extension frame, along with elastic members and stoppers, allows for adjustable extension and retraction to accommodate different sizes and keep clothing taut through mechanical force application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the hanger structure is fixed and compact, then it is easy to store and handle, but it cannot accommodate clothing of various sizes
Solution Approach 1:
The hanger is divided into multiple segments including a support frame, extension frames, and multi-joint links that can move independently. The extension frames can be extended outward from the support frame to increase width for larger garments, while remaining compact when retracted for smaller items.
Solution Approach 2:
The hanger employs dynamic components including a moving bar that can elevate vertically, extension frames that can protrude outward, and multi-joint links that rotate to change length. These dynamic elements allow the hanger to adapt its dimensions to match different clothing sizes while maintaining a compact form when not in use.
2Adaptability or versatility
If the hanger extends in both directions, then it can accommodate various clothing sizes, but it becomes difficult to control extension and retraction
Solution Approach 1:
The hanger incorporates elastic members that automatically provide restoring force to return the extension frames to their retracted position after being extended. The multi-joint links with rotation joints enable automatic length adjustment through gravitational force and elastic member action, reducing the need for manual control while maintaining ease of operation.
3Stability of the object's composition
If mechanical force is applied to keep clothing taut, then clothing maintains proper shape, but the hanger structure becomes more complex
Solution Approach 1:
The hanger uses elastic members positioned at strategic locations to apply counteracting forces that keep the clothing taut. These elastic members provide continuous mechanical force to counterbalance the gravitational force on the clothing, maintaining proper garment shape without requiring complex active control mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the hanger to stably support clothing of various sizes by extending and retracting, while maintaining clothing tautness and ease of use through mechanical force application.
Implementation Method 1
an elastic member providing an upward elastic force to the moving bar
Implementation Method 2
a compression spring configured to provide an elastic force to the stopper in a direction in which the protrusion hangs on the hanging part
Implementation Method 3
a multi joint link which is embedded in the support part and rotatably connected to the elevating body, and the length of which varies according to the elevation of the elevating body
