Modular Friction Pad Pinch Clip Hanger for Secure Garment Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pinch clip garment hangers fail to adequately grip garments, leading to slippage and accidental release when clips touch other objects, and the use of friction-enhancing materials like rubber is laborious and costly to manufacture.
Innovation Solution
The design incorporates pivotally secured jaw members with biasing springs and modular friction pads that can be securely attached using a securing ring or a securing member, allowing for improved grip and preventing accidental release by ensuring the jaws remain closed even when hangers are stacked.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If friction pads are made from rubber or rubber-like material to increase friction coefficient, then gripping ability is improved, but manufacturing complexity and cost increase due to adhesive application or molding processes
Solution Approach 1:
The friction pad is segmented from the jaw member, allowing it to be a separate replaceable component. This segmentation enables simpler manufacturing of the jaw member while maintaining the friction-enhancing function through the separate pad component that can be attached via various methods including adhesives, mechanical fasteners, or interference fits.
Solution Approach 2:
The invention changes the material parameter by using thermoplastic material for the friction pad that can be molded in various shapes. This allows the pad to be formed with specific geometric features (flat, contoured, or complementary shapes) that optimize friction and grip while enabling efficient molding manufacturing processes.
2Stability of the object's composition
If pinch clips are designed to touch hangers or adjacent objects for stability, then hanger stability is improved, but garment security deteriorates because clips may open and release the garment
Solution Approach 1:
The biasing spring is pre-loaded to maintain constant pressure on the garment between the jaw members. This preliminary anti-action counteracts any forces that might cause the jaws to open, including contact between hangers or adjacent objects, thereby preventing accidental garment release while maintaining system stability.
3Device complexity
If jaw members are integrally molded to the cross member for simplicity, then device complexity is reduced, but adaptability and ease of repair deteriorate
Solution Approach 1:
The friction pad is segmented as a separate component from the jaw member, enabling it to be replaced independently. This segmentation provides adaptability for different pad materials and shapes while keeping the jaw member structure simple and integrally molded to the cross member.
Solution Approach 2:
The friction pad is designed as a consumable component that can be discarded when worn or damaged and recovered/replaced without affecting the jaw member or cross member. This enables easy maintenance and adaptation while preserving the simplicity of the main structural components.
