Vehicle Door Inner Handle Cable Support Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle door handle devices require separate mounting devices for lock and open cables, leading to cable drop-off and incorrect cable attachment during assembly due to similar shaped and dimensioned end portions.
Innovation Solution
An inner handle housing with a cable support part that includes distinct configurations for receiving the end portions of the open and lock cables, preventing incorrect attachment and cable drop-off, and eliminating the need for separate mounting devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate mounting devices are used for lock cable and open cable, then the cables can be securely mounted, but cable drop-off can occur and assembly complexity increases
Solution Approach 1:
The patent combines multiple separate mounting devices into a single integrated cable support structure with multiple recesses. This single support structure simultaneously secures both the lock cable and open cable, eliminating the need for separate mounting devices while maintaining secure cable attachment and preventing cable drop-off.
2Ease of manufacture
If similar shaped cable end portions are used, then manufacturing is simplified, but incorrect cable attachment during assembly occurs
Solution Approach 1:
The patent applies local quality by providing distinct recess configurations for different cable types within the same cable support structure. Each recess has unique characteristics (such as different shapes, sizes, or orientations) that correspond to specific cable end portions, enabling workers to correctly identify and attach each cable to its designated mounting location without confusion.
3Reliability
If multiple separate mounting devices are used, then each cable can be individually secured, but assembly time increases
Solution Approach 1:
The patent merges multiple separate mounting devices into a single integrated cable support structure that can secure both cables simultaneously. This consolidation allows workers to complete the cable mounting operation in one step rather than sequentially mounting each cable separately, significantly reducing assembly time while maintaining reliable cable securing.

AI summary
A vehicle door handle device for attaching to a door panel for operating a door latching device and a door locking device comprises an operation handle and a lock knob. The operation handle operates the latching device to unlatch and open the door. The lock knob operates the locking device to lock and unlock the door. An open cable links the operation handle to the latching device. A lock cable links the lock knob to the locking device. An inner handle housing houses the operation handle and the lock knob. The handle housing includes a cable support part defining a first space for receiving an end portion of the open cable, and a second space for receiving an end portion of the lock cable. The cable support part is configured to prevent one of the end portion of the open cable and the end portion of the lock cable from being received in one of the first space and the second space.
