Tubular Vehicle Lighting Fixture with Nested Lamp Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle lighting fixtures face difficulties in efficiently attaching unitized constituent elements to a housing, leading to reduced operation efficiency.
Innovation Solution
A vehicle lighting fixture configuration utilizing a tubular support body to house and securely attach multiple lamp units, with the first lamp unit positioned internally and the second lamp unit externally, allowing for easy attachment and preventing light mixing through a light-shielding property.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If constituent elements are attached independently to a main housing, then each element can be individually positioned, but the attachment process becomes complex and operation efficiency is reduced
Solution Approach 1:
The patent merges multiple constituent elements (reflector, light source, lens, and housing) into a single pre-assembled lamp unit. This allows the entire unit to be attached to the main housing as one component rather than assembling multiple parts separately, thereby simplifying the attachment process and improving operation efficiency while maintaining precise positioning of all elements
Solution Approach 2:
The constituent elements are pre-assembled into a complete lamp unit before being installed in the main housing. This preliminary assembly ensures proper positioning and alignment of all components (reflector, light source, lens) is achieved during manufacturing, eliminating the need for complex adjustment and attachment procedures during installation
2Volume of moving object
If multiple lamp units are arranged in a compact configuration, then the overall size is reduced, but light from different units may mix and interfere with each other
Solution Approach 1:
The patent arranges multiple lamp units in a nested configuration where the first lamp unit is positioned inside the inner space of the tubular support body and the second lamp unit is arranged along the outer peripheral surface. This nested arrangement minimizes the overall volume of the lighting fixture while maintaining spatial separation between different light sources
Solution Approach 2:
The tubular support body serves as an intermediary structure between the first and second lamp units. It provides physical separation and light shielding between the different lamp units, preventing light mixing while maintaining a compact overall structure. The tubular support body acts as a mediator that enables close proximity arrangement without optical interference

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enhances operation efficiency by allowing easy attachment of multiple lamp units, miniaturization, and maintains the intrinsic functions of separate colored light beams by optically shielding the lamp units from each other.
Implementation Method 1
The tubular support body has a light-shielding property and configured to optically shield the first lamp unit and the second lamp unit from each other
