Vehicular Lamp Unit Coupling for Simplified Panel Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicular lamps, such as those described in Patent Literature 1, require separate attachment of lamp units to a panel member, making the installation process cumbersome.
Innovation Solution
A vehicular lamp design featuring lamp units with coupling portions that allow for integration and attachment of multiple units to a vehicle panel, utilizing a common wiring component and simplified assembly through hot plate welding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If lamp units are separately attached to the panel member, then each lamp unit can be independently assembled and replaced, but the installation process becomes cumbersome and time-consuming
Solution Approach 1:
The patent combines multiple lamp units into a single integrated lamp assembly that is attached to the vehicle as one unit. The lamp assembly includes a housing that accommodates multiple lamp units (turn signal lamp unit, stop lamp unit, clearance lamp unit) and is mounted to the vehicle body through a single attachment process, eliminating the need to separately attach each lamp unit to the panel member.
2Adaptability or versatility
If multiple lamp units are separately attached to the panel member, then each unit can be independently positioned, but the overall attachment process becomes complex and difficult
Solution Approach 1:
The patent segments the lamp system into a modular lamp assembly with a housing that contains multiple lamp units. Each lamp unit maintains its functional independence within the integrated assembly, allowing for standardized positioning and simplified attachment to the vehicle body as a complete unit rather than separate components.

AI summary
A vehicular lamp includes a plurality of lamp units. Each of the plurality of lamp units includes a light emitting element, a lens disposed on a front side relative to the light emitting element, and a body supporting the light emitting element. The body of at least one of the plurality of lamp units includes a coupling portion configured to couple the body of the at least one of the lamp units with the body of another one of the lamp units.
