Vehicle Door Mounting Module With One-Motion Electrical Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting modules for motor vehicle doors require separate steps for fastening and electrical connection of extension functional components, which complicates the manufacturing process and may involve sealing electrical cables through wet-dry space separations.
Innovation Solution
A mounting module that allows for a single mounting movement to both fasten and electrically connect extension functional components, such as a door handle unit, by incorporating a mechanical interface and contact unit, enabling pre-contacting or simultaneous final fastening and electrical contacting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate steps are used for fastening and electrical connection of extension functional components, then reliability of connections is improved, but manufacturing complexity and time increase
Solution Approach 1:
The patent combines the mechanical fastening function and electrical connection function into a single integrated mounting movement. The mounting module includes both a mechanical interface for fastening and a contact unit for electrical contacting, allowing both functions to be performed simultaneously in one operation, thereby reducing manufacturing complexity while maintaining connection reliability
Solution Approach 2:
The mounting module is designed with multi-functionality, serving both as a mechanical fastening device and an electrical connection device. The same mounting movement that secures the extension functional component mechanically also establishes the electrical contact, making the mounting module a universal component that handles both fastening and electrical connection tasks
2Ease of manufacture
If electrical cables are passed through the mounting module carrier, then electrical connection is achieved, but sealing complexity increases due to wet-dry space separation requirements
Solution Approach 1:
The patent extracts the electrical cable from the mounting module carrier by providing electrical contacts that are integrated into the mounting module itself. The contact unit includes electrical contacts that directly contact the extension functional component without requiring cables to pass through the mounting module carrier, thereby eliminating the sealing complexity associated with wet-dry space separations
Solution Approach 2:
The electrical contacts in the contact unit serve as intermediaries between the extension functional component and the electrical system. Instead of using cables that would require sealing through the mounting module carrier, the electrical contacts provide a direct contact path that eliminates the need for complex sealing arrangements
