Clip With Segmented Wire Insertion Hole for Secure Panel Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clips for attaching wire members to panel members suffer from reduced fitting capability due to the escape of repulsive force through a slit in the main part, which compromises the secure attachment of the wire member.
Innovation Solution
A clip design featuring a head part with a cylindrical wire insertion hole and a single-body main part that extends downward, equipped with a pair of arms and legs that flex to engage with the panel member's fitting hole, preventing repulsive force escape and ensuring secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a slit is provided in the main part to allow wire insertion, then the wire member can be easily inserted and held, but the repulsive force escapes through the slit and fitting capability deteriorates
Solution Approach 1:
The wire insertion hole is segmented into multiple sections: an insertion section with a larger diameter that allows easy wire insertion, and a holding section with a smaller diameter that prevents wire escape. This segmentation allows the structure to simultaneously provide easy insertion while maintaining structural integrity for reliable fitting.
Solution Approach 2:
Different sections of the wire insertion hole have different local qualities - the insertion section has a larger diameter for ease of insertion, while the holding section has a smaller diameter for secure retention. This local variation in dimensions allows the structure to fulfill multiple functions without compromising overall reliability.
2Ease of operation
If the wire insertion hole has a large diameter for easy insertion, then wire insertion is facilitated, but the holding capability for varying wire diameters is reduced
Solution Approach 1:
The wire insertion hole is divided into an insertion section with larger diameter for easy insertion and a holding section with smaller diameter for secure retention. This segmentation allows the structure to accommodate varying wire diameters while maintaining both ease of insertion and holding capability.
Solution Approach 2:
The clip structure incorporates flexibility through the resilient main part that can deform during insertion and then return to its original shape to secure the wire. This dynamic behavior allows the holding section to adapt to different wire diameters while maintaining secure retention.
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 clip enhances fitting capability by maintaining the repulsive force and securely attaching the wire member to the panel, while the ribs on the wire insertion hole accommodate varying wire diameters and the slit facilitates easy insertion.
Implementation Method 1
the main part 120 is fitted to the plate by utilizing a repulsive force of flexure which is exerted on the pair of legs 140, 140
Implementation Method 2
three ribs 14 are formed on an inner peripheral face of the head part 10. The ribs 14 extend in a direction along an inserting direction of the flexible wire W... the ribs 14 increase frictional force between the flexible wire W and the head part 10, so that it is possible to prevent the flexible wire W from falling out
