Rotating Joint Wire Layout With Axial Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiring configurations between rotatably connected members, such as a vehicle body and a door, result in excessive movable amounts of electrical wires due to route differences during door opening and closing, leading to inefficient routing and potential damage.
Innovation Solution
The wiring member arrangement involves disposing electrical wires in parallel to the rotational axis between the connected members, reducing the movable amount by maintaining a consistent length and minimizing route differences through parallel alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electrical wires are disposed in a position away from the rotational axis of the door hinge, then the wires can be routed between the vehicle body and the door, but the movable amount of the electrical wires becomes excessively large due to route differences during door opening and closing
Solution Approach 1:
The patent applies dimensionality change by transitioning from radial wire arrangement (perpendicular to rotational axis) to axial wire arrangement (parallel to rotational axis). This dimensional reorientation fundamentally changes the wire's path characteristics, allowing the wires to move primarily in the axial direction rather than experiencing large radial displacements during door rotation, thereby reducing the movable amount while maintaining routing functionality
2Length of moving object
If electrical wires are disposed closer to the door hinge, then the movable amount is reduced, but the routing becomes more complex and may interfere with the hinge mechanism
Solution Approach 1:
The patent resolves this contradiction by utilizing the axial dimension (parallel to rotational axis) for wire placement, which provides sufficient space away from the hinge mechanism while maintaining minimal movable amount. This axial arrangement avoids interference with the hinge mechanism and simplifies routing compared to traditional radial arrangements, as the wires can be neatly organized along the axial direction without complex bends or loops

AI summary
An arrangement structure of a wiring member includes: a first member; a second member connected to the first member to be rotatable around a rotational axis; and a plurality of electrical wires having a part disposed at least between the first member and the second member, wherein the plurality of electrical wires are disposed in parallel to each other in a direction in which the rotational axis extends in the part of the plurality of electrical wires disposed between the first member and the second member.
