Integrated Cable Lug Housing Assembly Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for installing a wiring harness in a vehicle are cumbersome, requiring separate connections for the housing and grounding cable, which complicates the attachment process.
Innovation Solution
An assembly comprising a housing with a cable lug and a positioning device that allows the cable lug to be pre-assembled, ensuring it is correctly positioned for a single operation with a fastening bolt that secures both the housing and the grounding cable, facilitating a streamlined installation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate connections are used for housing and grounding cable, then reliable electrical connection is achieved, but installation complexity increases
Solution Approach 1:
The patent combines the housing mounting function and grounding cable connection function into a single integrated cable lug structure. The cable lug simultaneously serves as the mounting element for securing the housing to the vehicle and as the electrical connection point for the grounding cable, eliminating the need for separate connections and simplifying the installation process while maintaining reliable electrical connection
2Reliability
If multiple separate fastening operations are performed, then secure attachment is achieved, but installation time increases
Solution Approach 1:
The integrated cable lug design allows a single fastening operation to simultaneously secure both the housing and establish the grounding connection. The mounting element is designed so that one fastener engages both the housing mounting opening and the cable lug retaining opening, enabling both attachment functions to be completed in one action rather than requiring multiple separate fastening operations
Solution Approach 2:
The cable lug is pre-assembled with the grounding cable connection prepared in advance, with the retaining opening positioned to align with the housing mounting opening. This preliminary preparation ensures that during final assembly, the fastening bolt can immediately engage both components without requiring additional alignment or adjustment steps, reducing installation time while maintaining secure attachment
3Adaptability or versatility
If cable lug position is not pre-determined, then assembly flexibility is maintained, but alignment precision deteriorates
Solution Approach 1:
The cable lug is pre-assembled into the housing receptacle with its position pre-determined by the receptacle geometry and positioning features. This preliminary positioning ensures that the retaining opening of the cable lug is precisely aligned with the mounting opening of the housing, providing accurate alignment for the fastening bolt while still allowing assembly flexibility through the standardized receptacle design that can accommodate different cable lug configurations
