Integrated Housing Electrical Feed Line Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical component housings in motor vehicles require complex and bulky external plug connections, which increase size, weight, and susceptibility to mechanical strains due to vibrations, especially in compact spaces where secure and sealed connections are necessary.
Innovation Solution
A housing design that integrates the electrical feed line directly, eliminating the need for external plugs and sockets by using internal contact means for electrical connection, which can be disconnectable and protected from environmental influences, and incorporates a sealing means for strain relief and simplified construction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external plug connections with locking means and seal elements are used, then secure electrical connection and sealing function are ensured, but housing volume and mass increase significantly
Solution Approach 1:
The patent merges the electrical connection function directly into the housing structure by integrating contact means into the housing wall itself, eliminating the need for separate external plugs and sockets. This integration reduces housing volume while maintaining secure electrical connection through direct contact between feed line contacts and housing contacts.
Solution Approach 2:
The patent extracts the plug and socket components from the housing system, removing these external attachments entirely. Instead, the housing provides built-in contact means that directly interface with the feed line, eliminating the volume occupied by external plugs, locking means, and associated seal elements.
2Reliability
If external plug connections with locking means are used, then secure plug connection is guaranteed, but device complexity increases
Solution Approach 1:
The patent combines the housing structure with electrical contact functionality by integrating contact means directly into the housing wall. This merging eliminates the need for separate plug and socket assemblies with their associated locking mechanisms, significantly reducing construction complexity while maintaining connection security.
Solution Approach 2:
The patent removes external plug connections and their locking means from the housing system. The security of electrical connection is maintained through integrated contact means that are part of the housing structure itself, eliminating the complexity of separate plug assemblies with multiple components.
3Reliability
If multiple seal elements and locking means are used, then secure contacting and sealing function are ensured, but manufacturing costs increase
Solution Approach 1:
The patent merges the sealing function into the integrated contact structure by providing a single seal element at the feed line penetration point. This eliminates the need for multiple separate seal elements associated with external plugs and sockets, reducing manufacturing complexity and cost while maintaining sealing effectiveness.
Solution Approach 2:
The patent removes external plug connections that require multiple seal elements and locking means. The sealing function is achieved through a single integrated seal at the feed line entry point, significantly reducing the number of components and associated manufacturing costs.
4Reliability
If external plug connections are used, then electrical connection can be made, but susceptibility to mechanical strains from vibrations increases
Solution Approach 1:
The patent merges the electrical connection directly into the housing structure with integrated contact means that are rigidly attached to the housing wall. This integration creates a robust connection that resists mechanical strains and vibrations better than external plug connections, which are subject to stress at connection points.
