Clothes hanger
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clothing hangers fail to accommodate clothing of various sizes effectively and keep garments taut, lacking adjustable mechanisms to extend and retract easily.
Innovation Solution
A clothing hanger with a vertical frame, support frames, a moving bar, and multi-joint links that allow extension frames to protrude or retract, combined with elastic elements and stoppers for adjustable support and tension, enabling easy extension and retraction to fit different sizes and maintain garment tautness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the hanger uses a fixed support frame structure, then the structure is simple and stable, but it cannot accommodate clothing of various sizes
Solution Approach 1:
The support frame is designed with movable extension frames that can protrude or retract along the support parts. The multi-joint links connect the extension frames to the elevating body, allowing the support frame to dynamically adjust its width and shape according to the size of the clothing being hung, thus achieving adaptability without requiring a completely different structure for each clothing size.
Solution Approach 2:
The support frame is divided into a center part and multiple extension frames that can move independently. Each extension frame is connected via multi-joint links, allowing segmented adjustment of the support width. This segmentation enables the hanger to adapt to various clothing sizes while maintaining a relatively simple overall structure.
2Adaptability or versatility
If the hanger uses an adjustable extension mechanism, then it can fit various clothing sizes, but the operation becomes more complex and difficult
Solution Approach 1:
The elevating body is connected to the extension frames through multi-joint links, creating a self-adjusting mechanism. When the elevating body moves up or down, it automatically drives the extension frames to protrude or retract through the linkage mechanism, eliminating the need for separate manual adjustment operations. The system adjusts itself based on the elevation position, making operation simple while maintaining adjustability.
3Adaptability or versatility
If the hanger uses elastic mechanisms to keep garments taut, then garment appearance is improved, but the device complexity increases
Solution Approach 1:
Elastic members are integrated into the linkage mechanism between the elevating body and extension frames. These elastic members automatically adjust the tension applied to the clothing based on the elevation position and clothing weight, maintaining optimal tautness without requiring complex active control systems. The elastic parameter changes with position, providing automatic tensioning.
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
The hanger effectively supports clothing of various sizes by adjustable extension frames and maintains garments taut through elastic mechanisms, enhancing usability and convenience.
Implementation Method 1
the multi-joint link pulls the extension frame such that the extension frame is inserted into the support part of the support frame, and wherein when the moving bar and the elevating body lower, the length of the multi-joint link increases and the multi-joint link pushes the extension frame
Implementation Method 2
The clothing hanger may further include an elastic member providing an upward elastic force to the moving bar
Implementation Method 3
The clothing hanger may further include a compression spring configured to provide an elastic force to the stopper in a direction in which the protrusion hangs on the hanging part
