Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light modules for motor vehicles face challenges in maintaining precise positioning of light sources, such as light-emitting diodes, relative to the collector, especially during replacements, which affects the quality of lighting and signaling.
Innovation Solution
The design incorporates an adapter with elastic return means and separate pressing and adjustment mechanisms to ensure precise positioning of the light source at the focus of the optical collector, allowing for easy replacement while maintaining alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the light source is fixed directly in the housing without an adapter, then the positioning precision is high, but the ease of replacement deteriorates
Solution Approach 1:
The system is divided into separate components: a housing, an adapter, and a light source. The adapter acts as an intermediary element that can be removed and replaced independently, allowing the light source to be easily changed while maintaining precise positioning through the adapter's design features such as positioning ribs and engagement mechanisms.
2Ease of repair
If an adapter is introduced to facilitate replacement, then the ease of replacement improves, but the device complexity increases
Solution Approach 1:
The adapter serves as an intermediary component between the housing and the light source. It simplifies the replacement process by providing a standardized interface that can be easily engaged and disengaged, while its integrated positioning features ensure that no additional complex alignment mechanisms are needed.
3Productivity
If multiple replacement operations are performed, then the productivity improves, but the positioning precision deteriorates due to cumulative errors
Solution Approach 1:
The adapter is pre-configured with positioning ribs, grooves, and engagement features that establish the correct position of the light source relative to the housing before the light source is even installed. This preliminary positioning mechanism ensures that every replacement operation starts from the same precise reference points, eliminating cumulative positioning errors.
Solution Approach 2:
The invention replaces complex mechanical alignment procedures with a standardized geometric interface system. The positioning ribs and grooves create a deterministic mechanical relationship that automatically ensures correct positioning without requiring skilled manual alignment or adjustment during each replacement operation.
