Modular Lamp with Retro-Reflective Lens for Day-Night Customization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lamps require complete redesign and are only visibly customizable under specific conditions, such as night-time illumination or vehicle operations like braking or signaling, failing to provide permanent identification both day and night.
Innovation Solution
A modular lamp design featuring a customizable outer lens with a recessed retro-reflective and inner LED-lit module, allowing customization to be visible both during the day and at night through the outer lens and illuminated inner lens respectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If complete lamp assembly is redesigned for customization, then personalization is achieved, but manufacturing complexity and resource requirements increase significantly
Solution Approach 1:
The lamp assembly is divided into modular components: a standard lamp housing and interchangeable customizable modules. Each module contains its own lens, reflector, and LED arrangement, allowing customization without redesigning the entire lamp assembly. The module can be easily removed and replaced with different customized modules.
Solution Approach 2:
The customizable elements are extracted into a separate removable module that can be independently manufactured and customized. This separates the customization function from the main lamp assembly, allowing the standard housing to remain unchanged while only the specific module needs customization for each application.
2Adaptability or versatility
If customization is achieved through complete lamp redesign, then personalization is permanent, but production time and resource allocation increase
Solution Approach 1:
The customizable modules are pre-manufactured with specific customizations (logos, patterns, text) before being integrated into the standard lamp housing. This allows customization to be done in advance during module production, rather than requiring complete lamp assembly redesign for each customization request, thereby maintaining high production efficiency.
3Productivity
If standard lamp design is used, then manufacturing is efficient, but personalization is not visible during daytime
Solution Approach 1:
The customizable module incorporates a retro-reflective lens that specifically enhances the visibility of the customized surface during daytime. The retro-reflective material reflects light back toward its source, making the customized logo or pattern clearly visible in daylight conditions, while the rest of the lamp maintains standard manufacturing efficiency.
4Loss of information
If retro-reflective material is added to enhance daytime visibility, then personalization is visible during day, but manufacturing complexity increases
Solution Approach 1:
The retro-reflective lens is merged with the customizable module as an integrated component rather than a separate addition. The retro-reflective material is applied directly to the module's lens or housing during module manufacturing, combining the daytime visibility enhancement with the customization function in a single integrated component that does not significantly increase overall manufacturing complexity.
Applied Scientific Principles

AI summary
Customizable modular lamp is made up of an outer lens (1) customized by known per se techniques, which covers a housing (2) provided with at least one recess in which is mounted a customizable module consisting of a retro-reflective lens (3) under which there is an inner customized lens (4) personalized by known per se techniques, under which there is a printed circuit board with LEDs (5) that is held in a holder (6) fastened to a cover (7) provided with at least one element (8) for ventilation. During the daylight, personalization is visible on the outer customized lens (1); in the darkness and - depending on the recipient's request - when activating the lights for changing direction, position or braking, customization becomes evident by lighting inside the lamp, on the surface of the inner customized lens (4).
