Hinge Wiring Guide Mechanism for Electronic Device Door
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In capillary electrophoresis devices, the mechanical stress on wires during door opening and closing leads to breakage and wear due to twisting, bending, pulling, and rubbing, which is not effectively addressed by existing hinge mechanisms.
Innovation Solution
A wiring guide mechanism featuring a hinge member that links a device body and a door, with retention members spaced apart along the hinge axis, allowing the retention members to rotate relative to each other, thereby reducing the mechanical stress on the wires.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wires pass through a fixed hinge mechanism, then the device structure is simple, but the wires are subjected to twisting, bending, pulling, and rubbing loads causing breakage and wear
Solution Approach 1:
The retention members are configured to rotate relative to each other around the hinge axis, transforming the static wire passage into a dynamic system. This rotation allows the wires to be gradually fed out during door opening, preventing bending and twisting loads while maintaining structural simplicity
Solution Approach 2:
Multiple retention members are distributed along the hinge axis at different positions. Each retention member independently manages wire passage, dividing the wire management function into segments that collectively reduce mechanical stress on the wires
2Reliability
If multiple retention members are distributed along the hinge axis, then the load on wires is reduced, but the device complexity increases
Solution Approach 1:
The retention members serve multiple functions: they guide wire passage, rotate to feed wires during door operation, and are distributed to manage multiple wires simultaneously. This multi-functionality reduces the need for separate wire management components, offsetting the complexity increase

AI summary
The present invention comprises: hinge members which rotatably link a device body and a door; wires which electrically connect the door side with the device body side; and a moving-side wiring retention member and fixed-side wiring retention member which retain the wires and are attached to the hinge members. The moving-side wiring retention member and the fixed-side wiring retention member are disposed spaced apart in an axial direction of the hinge members. The moving-side wiring retention member and the fixed-side wiring retention member rotate relative to each other on the same axis in accordance with a rotation operation of the door.
