Integrated Cable End Fitting for Latch Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional latch mechanisms face difficulties in cable installation due to the complexity of connecting multiple cables through small openings, which makes the assembly process time-consuming, costly, and prone to errors, and also complicates disassembly for maintenance without damaging components.
Innovation Solution
A cable end fitting with a sheath and base plate design that allows for the simultaneous installation of multiple cables, featuring bores and a contoured housing to simplify the assembly process, and a method involving a cable assembly with a back plate and slot mechanism to secure the cables within the latch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple cables are connected through small openings in conventional latch mechanisms, then the locking and releasing functions are achieved, but the assembly process becomes time-consuming, costly and prone to errors
Solution Approach 1:
The patent combines multiple cable routing functions into a single integrated cable access assembly. The housing with multiple openings and the base plate with multiple cable guides work together as one unit, allowing multiple cables to be installed simultaneously through a single assembly operation rather than multiple separate operations.
Solution Approach 2:
The cable access assembly serves multiple functions: it provides structural support for cable routing, guides multiple cables through designated paths, prevents cable interference with other components, and facilitates simultaneous installation of multiple cables. This multi-functional design eliminates the need for separate components for each function.

The housing with multiple openings and the base plate with multiple cable guides work together as one unit, allowing multiple cables to be installed simultaneously through a single assembly operation rather than multiple separate operations.
Solution Approach 2:
The cable access assembly is segmented into distinct functional zones: the housing with openings for cable entry, the base plate with guides for cable routing, and the retention mechanism. This segmentation allows each component to perform its specific function efficiently while simplifying the overall assembly process.
3Ease of repair
If cables are installed in conventional latch mechanisms, then the cable functions are achieved, but disassembly for maintenance is difficult and may damage components
Solution Approach 1:
The cable access assembly is segmented into distinct functional zones: the housing with openings for cable entry, the base plate with guides for cable routing, and the retention mechanism. This segmentation allows each component to perform its specific function efficiently while simplifying the overall assembly process.
Solution Approach 2:
The cable guides and retention mechanism are pre-configured in the base plate to automatically guide cables into their proper positions and secure them during installation. This preliminary configuration ensures that cables are properly positioned and retained from the start, facilitating easier removal during maintenance without damaging components.

AI summary
A cable end fitting for use in a latch is provided including a sheath for surrounding a portion of a first cable and a second cable. A portion of the sheath, including a first end is positioned within a housing. A base plate is coupled to the second end of the sheath. A first bore and a second bore extend through the base plate and the sheath. The base plate retains the cable end fitting in a position in the latch.
