Exterior Mirror Plug Connection Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing exterior rear view mirror assemblies for motor vehicles face challenges in simplifying the assembly and replacement of electrical components with plug connections, which require high time expenditure due to complex electrical connections and limited adjustability.
Innovation Solution
An exterior rear view mirror design featuring a clip connection between the housing and a fixed second plug part, allowing for a one-handed assembly and disassembly of plug connections using a connection cable with a first plug part attached to the electrical component, enabling easy exchange of components without limiting adjustability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical components are connected using traditional wiring methods inside the exterior rear view mirror housing, then reliable electrical connection is achieved, but assembly time and replacement time increase significantly
Solution Approach 1:
The electrical connection system is segmented into a fixed plug part integrated with the housing and a movable plug part connected to the electrical component. This segmentation allows the movable plug part to be easily disconnected and reconnected, significantly reducing assembly and replacement time while maintaining connection reliability through the plug interface design with corresponding contact elements.
2Loss of time
If electrical components are made easily replaceable with simple connections, then assembly time is reduced, but connection reliability and stability deteriorate
Solution Approach 1:
The movable plug part is designed to nest within the fixed plug part during connection. The movable plug part features a plug body that inserts into the fixed plug part's receptacle, with contact elements that engage securely. This nested structure provides stable mechanical retention and reliable electrical contact while allowing easy disconnection by simple withdrawal motions.
3Stability of the object's composition
If the plug connection is fixed rigidly in the housing, then connection stability is improved, but adjustability of electrical components is limited
Solution Approach 1:
The electrical connection system incorporates dynamic elements including a movable plug part that can be disconnected and reconnected, and flexible connection cables that allow movement. This dynamic design enables the electrical components to be adjusted to different positions while maintaining stable electrical connection through the flexible cable and plug interface, rather than requiring rigid fixed mounting.
4Reliability
If complex electrical connections are used to ensure reliability, then connection stability is improved, but assembly complexity increases
Solution Approach 1:
The fixed plug part is merged with the housing structure as an integrated component, and the movable plug part is merged with the electrical component assembly. This merging eliminates the need for separate mounting brackets and complex wiring harnesses, reducing assembly complexity while maintaining connection reliability through the unified plug interface design with built-in contact elements.
