Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light line arrangements with reflectors face challenges in achieving precise alignment with LED light sources, making it difficult to achieve desired asymmetrical light output, such as illuminating obliquely positioned vertical wall areas.
Innovation Solution
A light band arrangement featuring a retaining spring with a planar surface and wing-like areas, allowing for precise alignment of the reflector via a snap-in connection, supported by the mounting rail, and designed to facilitate oblique alignment, ensuring accurate positioning of the reflector relative to the light bar.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a reflector is used to achieve asymmetrical light output, then the light distribution can be optimized for specific areas, but the alignment precision between the reflector and LED light source becomes difficult to achieve
Solution Approach 1:
The retaining spring is pre-formed with integrated alignment features (planar surface area and wing-like area with slot) that automatically guide the reflector into the correct position during assembly, eliminating the need for complex post-assembly alignment procedures
Solution Approach 2:
The retaining spring acts as an intermediary component between the light bar and the reflector, providing both mechanical retention and precise alignment through its specially designed geometric features, thereby decoupling the mounting function from the alignment function
2Manufacturing precision
If traditional mounting methods are used for the reflector, then the assembly process becomes complex and time-consuming, but achieving precise alignment is difficult
Solution Approach 1:
The retaining spring is pre-formed with integrated alignment features (planar surface area and wing-like area with slot) that automatically guide the reflector into the correct position during assembly, eliminating the need for complex post-assembly alignment procedures
Solution Approach 2:
The retaining spring's geometric features (planar surface area contacting the light bar and wing-like area with slot for the reflector) automatically self-align the components during assembly without requiring external alignment tools or complex adjustment mechanisms
3Reliability
If the retainin spring is supported on the mounting rail, then the alignment reliability is improved, but the device complexity increases
Solution Approach 1:
The mounting rail serves multiple functions: it provides mechanical support for the light bar, supports the retaining spring to ensure stable alignment, and acts as a reference structure for the overall assembly, thereby reducing the need for separate alignment fixtures
