Auxiliary Lamp Adapter for CHMSL Mounting Without Drilling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Light truck owners face challenges in adding auxiliary lighting to Center Height Mounted Stop Lamps (CHMSL) without damaging the vehicle body or allowing water intrusion, as conventional methods require additional holes in the sheet metal.
Innovation Solution
An adapter assembly that mounts auxiliary lamps adjacent to the primary lamp using pre-existing lamp mounting provisions, eliminating the need for new holes in the vehicle body and incorporating a sealing device to prevent water intrusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional holes are drilled in the vehicle sheet metal to mount auxiliary lighting, then auxiliary lighting can be added, but the vehicle body integrity is damaged and water intrusion risk increases
Solution Approach 1:
The adapter assembly is nested within the existing CHMSL housing structure, utilizing the pre-formed aperture and mounting provisions. The auxiliary lamp housing fits inside the CHMSL housing, and the adapter integrates both lamp structures without requiring external modifications to the vehicle body, thus avoiding additional holes and preserving body integrity.
Solution Approach 2:
The adapter assembly serves multiple functions: it provides mounting structure for auxiliary lamps, maintains the existing CHMSL functionality, provides electrical connections for both primary and auxiliary lamps, and seals the aperture to prevent water intrusion. This multi-functional design allows auxiliary lighting addition without compromising the original system or vehicle integrity.
2Ease of manufacture
If conventional mounting methods are used for auxiliary lighting, then installation is simple, but installation damage to the vehicle body occurs
Solution Approach 1:
The adapter assembly is pre-configured with all necessary mounting features, electrical connections, and sealing elements before installation. The electrical connectors are pre-routed through the adapter housing, and the sealing member is pre-positioned, allowing the entire assembly to be installed as a single unit without requiring on-site drilling, cutting, or complex wiring modifications to the vehicle body.
3Object-affected harmful factors
If the adapter assembly is installed using the sealing device, then water penetration is prevented, but the installation complexity increases
Solution Approach 1:
The sealing function is merged into the adapter housing structure itself. The sealing member is integrated with the adapter housing and works in conjunction with the housing's own structural features to create the seal, rather than being a separate, complex sealing system. This integration simplifies the overall installation while maintaining effective water protection.

AI summary
An auxiliary lighting adapter housing for mounting one or more auxiliary lamps adjacent to a primary lamp mounted onto a lamp aperture provided within a portion of a vehicle. The adapter housing includes an adapter aperture, sized and positioned to align and communicate with the lamp aperture. One or more auxiliary mounts of the adapter housing are adapted to receive and accommodate auxiliary lamps. The housing includes multiple passages, and each passage connects a specific auxiliary mount to the adapter aperture.
