Wire Harness Routing Guide Member Dynamics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire harness routing devices face issues with reduced usable space due to large accommodation areas and hindered slider movement when the parallel state of the rail and accommodation portion is shifted, causing the guide portion to be pressed against the inner wall.
Innovation Solution
A wire harness routing device with a guide member connected to the slider, allowing it to approach, separate, and incline, supported by elastic members and attachment portions, enabling smooth movement even when the rail and accommodation portion are not parallel, thus preventing the guide member from being hindered by the inner wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the wire harness is folded back in a U shape and accommodated in the accommodation portion, then the wire harness can be accommodated, but the area taken up by the accommodation portion is large
Solution Approach 1:
The guide member is nested within the accommodation portion, allowing the wire harness to be routed through the guide member while the guide member itself is contained within the accommodation portion. This nested configuration reduces the overall space required compared to external routing.
Solution Approach 2:
The guide member extends in the vertical direction (upward from the floor surface) rather than only horizontally, utilizing the vertical dimension to route the wire harness. This dimensional change allows the accommodation portion to have a smaller horizontal footprint while still accommodating the wire harness effectively.
2Stability of the object's composition
If the guide portion is connected to the slider at a fixed distance, then the connection is stable, but the slider is hindered from moving when the parallel state is shifted
Solution Approach 1:
The connection between the guide member and slider is made dynamic rather than fixed. The guide member can change its length and orientation in response to shifts in the parallel state between the rail and accommodation portion, allowing the slider to move smoothly without being constrained by a fixed-distance connection.
Solution Approach 2:
The guide member's parameters (length, orientation) are made variable to adapt to changes in the system configuration. When the parallel state shifts, the guide member adjusts its parameters to maintain proper connection and guide the wire harness, preventing slider movement hindrance while preserving connection stability.

AI summary
A wire harness routing device includes: a rail for a sliding seat, which is installed on a floor surface of a vehicle; a slider that is slidably attached to the rail; a wire harness extending from the sliding seat side; a guide member configured to connect the wire harness to the slider, and to guide the wire harness to the side of the rail and in a direction along the rail; and an accommodation portion that is provided to the side of the rail, and that accommodates the wire harness that is guided by the guide member so that the wire harness is movable along with the movement of the slider, wherein the guide member is connected to the slider to be able to approach and separate from the slider, and to be inclined to the slider.
