Automotive Cable Bracket With Abutment Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automotive cable holding systems face difficulties in mounting the manipulator unit on the vehicle body, particularly on the lower side of the rear parcel shelf, and struggle to securely resist the pulling force of the cable, leading to increased mounting time and potential dislodgement.
Innovation Solution
An automotive cable holding system featuring a bracket with an engagement portion and a clip portion that are inserted into a vehicle body opening, where the bracket is attached to a thin steel sheet cross member, allowing easy mounting and secure cable retention by abutting the inner circumferential surface, preventing dislodgement under tension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the manipulator unit is mounted on the vehicle body using pins, then the mounting strength is sufficient to resist cable pulling force, but the mounting process becomes complex and time-consuming
Solution Approach 1:
The bracket is divided into distinct functional segments: an engagement portion for inserting into the vehicle body opening, a clip portion for clamping the cable, and an abutment surface for bearing pulling forces. This segmentation allows each part to perform its specific function efficiently, enabling simple insertion mounting while maintaining sufficient strength to resist cable pulling forces.
2Adaptability or versatility
If the manipulator unit is mounted on the lower side of the rear parcel shelf, then the cable routing is optimized, but the fastening work becomes difficult
Solution Approach 1:
The bracket design enables self-aligning insertion into the vehicle body opening. The engagement portion is configured to automatically orient itself during insertion, eliminating the need for precise pre-positioning or complex alignment procedures. This self-service characteristic makes mounting equally easy whether on the lower side of the rear parcel shelf or other locations, while still allowing optimized cable routing.
3Ease of operation
If the bracket uses only a clip portion for engagement, then the mounting is simple, but the cable pulling force may cause dislodgement
Solution Approach 1:
Different portions of the bracket are assigned different functional qualities: the engagement portion provides insertion and positioning, the clip portion provides cable clamping, and the abutment surface provides force bearing capacity. This local differentiation of qualities allows the bracket to achieve both simple insertion mounting and reliable resistance to cable pulling forces, preventing dislodgement while maintaining ease of installation.

AI summary
The present invention relates to an automotive cable holding system for securing a vehicle body to a cable which is connected at one end to a locking mechanism for a rear seat backrest and at the other end to a releasing mechanism. The automotive cable holding system includes a bracket for holding an end of the cable and an insertion opening in the vehicle body into which the bracket is inserted, wherein the bracket has provided thereon abutment surfaces which abut the inner circumferential surfaces of the insertion opening, an engagement portion extending further outwards than the abutment surfaces at a position lying further inwards than the insertion opening inside the vehicle body and a clip portion disposed on the opposite side to the engagement portion inside the vehicle body.
