Vehicle Lamp Reuse Screening in Sealed Lamp Assemblies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of modern vehicle lamps makes component replacement difficult, and damaged lamps are often discarded entirely due to the inability to identify reusable parts, leading to increased costs and environmental waste.
Innovation Solution
A method involving electric circuit functionality tests, illumination tests, and visual inspections to identify reusable components, followed by a process to separate and salvage these components without further damage, allowing for remanufacturing into new lamp assemblies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive sealing is used to prevent moisture entry in vehicle lamp assemblies, then reliability is improved, but ease of repair deteriorates
Solution Approach 1:
The lamp assembly is divided into separable components (housing, lens, internal components) that can be independently accessed. The adhesive seal is applied in a manner that allows controlled separation without damaging the housing or lens, enabling component replacement while maintaining the sealed structure during normal operation.
Solution Approach 2:
Internal components are extracted from the sealed housing structure for replacement or repair. The adhesive seal allows these components to be removed and reinstalled without compromising the moisture barrier, enabling maintenance while preserving reliability.
2Reliability
If component complexity increases in vehicle lamps, then reliability is improved, but ease of repair deteriorates
Solution Approach 1:
The complex lamp assembly is segmented into distinct functional modules (light sources, reflectors, housings, electrical components). Each module can be independently tested and replaced, simplifying the repair process despite the overall system complexity.
Solution Approach 2:
Individual components that fail are identified and removed for replacement, while functional components are retained and reused. This selective replacement approach maintains reliability without requiring complete assembly replacement.
3Reliability
If complete lamp assembly replacement is performed after damage, then reliability is improved, but loss of substance deteriorates
Solution Approach 1:
After damage or failure, each component of the lamp assembly is individually assessed for functionality. Working components are recovered and reused in repaired assemblies, while only damaged components are discarded. This dramatically reduces waste compared to complete assembly replacement.
Solution Approach 2:
Repair efforts are focused locally on only the damaged or failed components rather than replacing the entire assembly. This localized approach preserves functional components and minimizes material waste while restoring lamp reliability.

AI summary
The present teachings relate to a method for identifying reusable components of a vehicle lamp assembly, the method including: i) performing an electric circuit functionality test on each component of a plurality of components of the vehicle lamp assembly; ii) performing an illumination test on each light source within the vehicle lamp assembly; iii) identifying which of the components of the plurality of components pass and/or fail the electric circuit functionality test; and iv) identifying which light sources pass and/or fail the illumination test.
