Vehicle Lamp Multi-Housing for Rear Module Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lamps require high-temperature heating of entire recycling-enabling hot meltable items for after-sale service operations, which is inefficient and costly, especially for large-sized components, and necessitate specialized chambers, increasing the complexity and cost of maintenance.
Innovation Solution
A vehicle lamp with a separable multi-housing design allows for after-sale service operations to be performed from the rear surface, using a rubber-based meltable item that is responsive and deconstructible, reducing the need for high-temperature heating and specialized chambers, and incorporating a multi-housing structure with a hole formation portion and coupling structures for secure module replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If high-temperature heating is applied to the entire housing fastening portion to enable after-sale service operations, then the hot meltable item can be melted and components can be replaced, but the time required for heating increases and specialized high-temperature chambers are needed
Solution Approach 1:
The housing is divided into multiple housings with separate fastening portions. Each housing fastening portion can be heated independently and locally, rather than heating the entire housing structure. This segmentation allows focused heating of only the necessary areas, reducing overall heating time and eliminating the need for specialized high-temperature chambers.
2Ease of repair
If high-temperature heating is applied to the entire housing fastening portion, then complete melting of the hot meltable item is achieved, but energy consumption increases
Solution Approach 1:
The heating process is applied locally to specific housing fastening portions rather than uniformly across the entire housing. This local quality approach ensures that energy is concentrated only where needed to melt the hot meltable items, significantly reducing overall energy consumption while still achieving complete melting of the necessary portions for component replacement.
3Strength
If the housing is designed as a single integrated structure, then structural strength is maintained, but after-sale service operations become complex and time-consuming
Solution Approach 1:
The housing is segmented into multiple separate housings that can be independently accessed and serviced. Each housing maintains its structural integrity through proper coupling structures, while the modular design allows technicians to access and replace components in one housing without affecting others, simplifying after-sale service operations.
4Adaptability or versatility
If recycling-enabling hot meltable items are used in housing fastening portions, then component recyclability is enabled, but the number of coupling structures increases
Solution Approach 1:
The hot meltable items are applied locally at specific coupling points between housings rather than throughout the entire structure. This localized application maintains recyclability at each coupling point while minimizing the overall number of coupling structures needed, as each housing can be independently accessed and serviced.

AI summary
A vehicle lamp with a separable multi-housing includes a housing that has a hole formation portion and a rear coupling portion on a rear surface of a housing body. The housing body has an internal space in which a module (e.g., an after-sale service target) is positioned and the internal space is covered by a lens. A light source unit can be securely held on the hole formation portion, and the module is taken out through the hole formation portion. The rear coupling portion is formed along an entire circumference of the hole formation portion at an edge of the housing body in such a manner as to have a protrusion structure. An operation of replacing the module can be performed through the hole formation portion. Particularly, a multi-housing can be coupled to the rear coupling portion using a replaceable housing meltable item, thereby covering the hole formation portion.
