Retractable Door Handle Cable Mounting Housing Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional retractable outside door handle assemblies for vehicles face issues with increased weight, cost, and compromised exterior beauty due to the need for long link mechanisms to enhance user operation convenience, which also lead to assembly challenges and reliability concerns.
Innovation Solution
A structure for connecting a door latch cable to a retractable outside door handle assembly, featuring a mounting housing with a guide groove and flanges that allows easy assembly and prevents mis-assembly, improving productivity and reducing costs by securely attaching the cable to the handle assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the link mechanism is made longer to elongate the protruding length of the outside door handle for user operation convenience, then the operation convenience is improved, but the weight, cost, and device complexity increase
Solution Approach 1:
The patent changes the structural parameters of the link mechanism by optimizing the arrangement and dimensions of links and connecting rods. This allows achieving the required protruding length for user convenience while controlling the overall weight and complexity through refined dimensional parameters rather than simply increasing all link lengths.
Solution Approach 2:
The link mechanism is divided into multiple discrete links and connecting rods that can be independently optimized. This segmentation allows each component to be designed with minimal necessary length, reducing overall weight and complexity while maintaining the functional protruding length through the coordinated arrangement of segments.
2Ease of operation
If the link mechanism is made longer to elongate the protruding length of the outside door handle for user operation convenience, then the operation convenience is improved, but the device complexity increases
Solution Approach 1:
The patent optimizes the geometric parameters and arrangement of the link mechanism components, achieving the desired protruding length through refined dimensional relationships rather than adding more components. This reduces device complexity while maintaining operational convenience.
Solution Approach 2:
The patent integrates multiple functions into the link mechanism structure, combining the protrusion function, cable transmission function, and actuation function into a coordinated system of links and rods. This merging reduces the number of separate components needed, thereby reducing device complexity.
3Ease of operation
If the outside door handle is installed to be protruded outside along the width direction of the vehicle, then the operation convenience is improved, but the exterior beauty deteriorates and running resistance increases
Solution Approach 1:
The patent implements a retractable link mechanism that dynamically adjusts the protruding length of the door handle. The handle can extend to a longer position for improved user operation convenience and retract to a shorter position to reduce running resistance and improve exterior aesthetics, thus resolving the contradiction through dynamic adaptability.

AI summary
A structure can be used for connecting a door latch cable to a retractable outside door handle assembly for a vehicle. A mounting housing is inserted into a case of the retractable outside door handle assembly in a longitudinal direction of the vehicle and hanged by and mounted at the case in a height direction of the vehicle. A door latch cable is movably installed at the mounting housing.
