Wire Harness Routing for Rotating Vehicle Seats
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire harness routing apparatuses face challenges in limited space installations and accommodating longer wire harnesses due to restricted space between the seat and vehicle base, especially when the seat rotation angle increases.
Innovation Solution
A wire harness routing apparatus is designed to be integrated with the rotation mechanism, where the case is positioned radially inward within the rotation mechanism, allowing for a circular configuration that accommodates longer wire harnesses and rotates with the seat, utilizing a base-side and seat-side pedestal system with a base-side fixing member and seat-side fixing portion to manage wire harness length and prevent tangling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wire harness routing apparatus is installed separately from the rotation mechanism on the bottom surface of the seat, then the wire harness can be accommodated, but the available installation space is reduced and the apparatus may not fit when space between the seat and vehicle base is limited
Solution Approach 1:
The wire harness routing apparatus is merged with the rotation mechanism by integrating the case into the rotation mechanism structure. The case is positioned on the inner side in the radial direction of the rotation mechanism, combining two previously separate functions into one unified structure, thereby eliminating the need for additional installation space while maintaining wire harness accommodation capability
Solution Approach 2:
The wire harness routing apparatus is nested within the rotation mechanism structure. The case is arranged inside the radial space of the rotation mechanism, utilizing the existing structural space rather than requiring separate installation area, thus solving the space constraint problem while preserving the wire harness routing function
2Adaptability or versatility
If the rotation angle of the seat is increased, then the wire harness length increases, but the rotation absorption case cannot be increased in size to accommodate the excess length
Solution Approach 1:
The wire harness routing apparatus incorporates dynamic elements including a slider that moves along a circular arc-shaped slide groove and a rotatable case that rotates with the seat. These dynamic mechanisms allow the system to adapt to varying rotation angles and wire harness lengths without requiring a fixed increase in case size, as the structure dynamically adjusts to accommodate the extended wire harness paths
Solution Approach 2:
The invention utilizes the radial dimension of the rotation mechanism by positioning the case on the inner side in the radial direction. This dimensional arrangement allows the wire harness to be routed through a three-dimensional path that accommodates longer lengths within the existing radial space constraints, effectively using spatial dimensionality to resolve the length accommodation problem
