Foldable Device Wire Routing With Limiting Portion and Pivot Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable electronic devices face the challenge of wire damage or tearing due to stretching or squeezing during the folding process, as existing fixation methods are inadequate.
Innovation Solution
The design incorporates a shell member with a limiting portion and pivoting modules that allow the wire to move integrally in any direction relative to the limiting portion, preventing damage during state transformations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the wire is fixed to the housing via adhesive to avoid displacement, then the wire positioning stability is improved, but the wire is easily torn due to stretching or squeezing during folding
Solution Approach 1:
The shell member is divided into multiple functional portions: base portions for mounting pivoting modules, limiting portions for guiding wire movement, and notches for wire passage. This segmentation allows each portion to independently address specific requirements - the limiting portions provide directional guidance while the pivoting modules provide rotational freedom, resolving the contradiction between positioning stability and damage prevention
Solution Approach 2:
The pivoting modules enable the wire to move dynamically between unfolded and folded states through rotational motion. The wire can move integrally in any direction relative to the limiting portion during state transformation, transforming the wire from a static fixed position to a dynamic adaptable position that avoids stretching and squeezing forces
2Strength
If the wire is allowed to move freely during folding, then the wire is prevented from being torn, but the wire positioning stability deteriorates
Solution Approach 1:
The limiting portion acts as an intermediary between the fixed shell member and the moving wire. It provides a controlled interface that guides wire movement along a predetermined path, allowing the wire to move freely in terms of direction control while maintaining positional stability through the structured guidance mechanism
Solution Approach 2:
The wire movement is constrained to a specific dimensional path defined by the limiting portion's geometry. The through hole in the limiting portion creates a controlled degree of freedom, allowing movement in one dimension while maintaining stability in other dimensions, thus resolving the contradiction between free movement and positioning stability
