Foldable Terminal Wire Fastening Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In foldable terminal devices, the wire connecting the two housings is prone to abrasion due to its movement within the third housing, leading to wear and potential failure.
Innovation Solution
A wire fastening assembly is used to secure the wire within the third housing, reducing its movement and abrasion by employing a magnetic assembly that clamps the wire between magnetic components, thereby limiting its freedom of movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the wire is allowed to move freely within the third housing during folding and expanding, then the terminal device can be folded and expanded smoothly, but the wire is prone to abrasion and wear
Solution Approach 1:
The patent applies local quality by creating a semi-closed housing structure with an opening area specifically designed to guide wire movement. The wire fastening assembly is positioned at a specific location within the housing to provide localized约束 (constraint) where needed, while maintaining openness in other areas to allow necessary movement for folding and expanding operations.
Solution Approach 2:
The wire fastening assembly acts as an intermediary component between the wire and the housing structure. It provides magnetic attraction to hold the wire in place, reducing direct contact and friction between the wire and housing walls, thereby minimizing abrasion while still allowing controlled movement.
2Reliability
If the wire is fastened securely to reduce movement, then wire abrasion is reduced, but the freedom of movement of the wire is restricted
Solution Approach 1:
The patent replaces traditional mechanical fastening methods (such as clips, screws, or adhesives) with a magnetic fastening system. The magnetic assembly provides attractive force to hold the wire in position without physical contact or rigid constraints, allowing the wire to maintain natural flexibility and movement capability while still being secured against excessive displacement and abrasion.
