Vehicle Auxiliary Machine Bracket With Rib Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicular auxiliary machines, such as side collision detection systems, face interference issues with seats during side collisions due to their placement between seats, which can damage the harness connecting portions and disrupt their functionality.
Innovation Solution
The arrangement structure includes a vehicular auxiliary machine mounted on a bracket fixed to the vehicle body, with a harness connecting portion located on a side of a seat, featuring vertical wall portions and ribs that span between the harness-side vertical wall portion and the base surface, preventing direct interference from the seat during a side collision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the auxiliary machine is disposed between seats in the vehicular width direction, then the auxiliary machine can be positioned in a location less likely to be affected by accidents, but the harness connecting portion may be directly interfered with and damaged when a seat is displaced during a side collision
Solution Approach 1:
The patent introduces a bracket as an intermediary structure between the auxiliary machine and the vehicle body. The bracket includes a base surface, vertical wall portions, and ribs that create a protective spatial relationship, preventing direct contact between the seat and the harness connecting portion while maintaining the auxiliary machine's functional position between seats.
Solution Approach 2:
The patent transitions from a two-dimensional placement (auxiliary machine directly between seats) to a three-dimensional protective structure (bracket with vertical wall portions and ribs extending in multiple directions). This dimensional change creates protective space around the harness connecting portion without relocating the auxiliary machine from its optimal position between seats.
2Ease of manufacture
If the harness connecting portion is located on a side of one of the seats, then the connection is simplified, but the harness connecting portion is more vulnerable to direct interference and damage during side collision
Solution Approach 1:
The bracket serves as a protective intermediary between the harness connecting portion and the seat. The vertical wall portion and rib structure physically separates the harness connecting portion from direct seat contact while maintaining the simplified side-located connection arrangement, thus preserving ease of manufacture while reducing damage risk.
Solution Approach 2:
The bracket structure provides beforehand protection by creating a physical barrier (vertical wall portion and rib) that prevents direct impact between the seat and harness connecting portion during side collision. This protective structure is built into the design from the beginning, cushioning the harness connecting portion against potential damage before any collision occurs.
3Volume of moving object
If the auxiliary machine is positioned close to the seat for compact arrangement, then space utilization is improved, but the auxiliary machine and harness connecting portion are more susceptible to interference during side collision
Solution Approach 1:
The bracket introduces vertical and lateral dimensions through its vertical wall portions and ribs, creating a protective envelope around the harness connecting portion. This allows the auxiliary machine to remain in a compact position between seats while the bracket extends in additional dimensions to provide collision protection, effectively using three-dimensional space efficiently.
Solution Approach 2:
The harness connecting portion is nested within the protective structure formed by the bracket's vertical wall portion and rib. This nesting arrangement allows the auxiliary machine to occupy minimal space between seats while being surrounded by the protective bracket structure that prevents direct seat contact during side collision.

AI summary
A vehicular auxiliary machine is disposed between seats arranged side by side in a vehicular width direction of a vehicle body. A bracket is a member on which the vehicular auxiliary machine is mounted, and which is fixed to the vehicle body. The vehicular auxiliary machine includes a harness connecting portion disposed in such a way as to locate on a side of one of the seats. The bracket includes a base surface and a pair of vertical wall portions. Further, the bracket includes a rib spanning between a harness connecting portion and the base surface, on a harness-side vertical wall portion of the paired vertical wall portions close to the harness connecting portion.
