Vehicle Lamp Housing Connector for Quick Light Source Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lamp assemblies make it difficult to replace light sources due to complex and inaccessible electrical connections, requiring users to navigate between the backing plate and engine components, which is unsafe and time-consuming.
Innovation Solution
A vehicle lamp assembly design featuring a housing with a first electrical connector that couples with a second connector attached to the vehicle's power source through a retainer mechanism, allowing easy insertion and removal of the housing from the backing plate, facilitating quick replacement of light sources without needing to access the engine compartment directly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the housing is permanently integrated with the backing plate and electrical connectors, then the structural integrity and electrical reliability are improved, but the ease of replacing light sources deteriorates
Solution Approach 1:
The lamp assembly is divided into separable components: the housing with light sources can be removed from the backing plate, and the electrical connectors are designed as separate attachable elements. This segmentation allows the housing to be easily detached for light source replacement while maintaining reliable electrical connections when assembled.
Solution Approach 2:
The electrical connectors are designed with dynamic attachment and detachment capabilities. The first electrical connector on the housing can be coupled with and decoupled from the second electrical connector on the backing plate, allowing the system to transition between connected and disconnected states for maintenance while ensuring reliable connection during operation.
2Ease of repair
If the electrical connectors are made accessible from the engine compartment, then the ease of replacing light sources is improved, but the safety risks and time required for replacement deteriorate
Solution Approach 1:
The electrical connectors are pre-positioned and integrated with the housing and backing plate structures. The first electrical connector is disposed on the housing and the second on the backing plate, arranged so that they automatically couple when the housing is inserted into the backing plate. This preliminary arrangement eliminates the need for separate access to the engine compartment during replacement.
Solution Approach 2:
The electrical connection functionality is extracted and integrated directly into the housing-backing plate interface. By incorporating the electrical connectors as part of the mechanical assembly interface, the patent eliminates the need for separate electrical access points in the engine compartment, allowing all replacement operations to be performed from the accessible backing plate side.
3Productivity
If the housing is designed for easy removal and reattachment, then the productivity of light source replacement is improved, but the complexity of the coupling mechanism deteriorates
Solution Approach 1:
The coupling mechanism is segmented into simple, discrete elements: the housing with its first electrical connector couples with the backing plate containing the second electrical connector. This segmentation avoids complex integrated locking mechanisms while enabling easy attachment and detachment through straightforward insertion and engagement of the connector components.
