Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If traditional luminaire structures are used in cleanrooms, then installation and electrical connection are simplified, but gaps and protrusions occur at splicing joints causing dust accumulation and disrupting airflow
Solution Approach 1:
The end cap is designed with a curved streamlined shape that smoothly transitions from the luminaire body, eliminating sharp edges and protrusions. This curved structure prevents dust accumulation and maintains laminar airflow patterns in the cleanroom environment while achieving seamless splicing appearance.
Solution Approach 2:
The end cap structure is integrated into the luminaire body through a nested design where the end cap is positioned within and conforms to the luminaire housing. This nesting approach creates a unified streamlined exterior without separate protruding components, achieving both aesthetic seamless splicing and functional airflow compatibility.
2Illumination intensity
If luminaire splicing is implemented, then continuous illumination is achieved, but gaps at joints create dust accumulation points
Solution Approach 1:
Adjacent luminaires are spliced together with their end caps forming a continuous seamless surface. The streamlined end cap design of one luminaire merges with the corresponding end cap of the adjacent luminaire, eliminating gaps and joints where dust could accumulate, while maintaining continuous illumination across the spliced boundary.
3Illumination intensity
If luminaire splicing is implemented, then continuous illumination is achieved, but airflow organization and HVAC compatibility are compromised
Solution Approach 1:
The curved streamlined end cap design eliminates sharp edges and protrusions that would disrupt laminar airflow. The smooth curved surface allows air to flow continuously over the luminaire surface without creating turbulence or eddies, maintaining HVAC system effectiveness while enabling continuous illumination through splicing.
4Shape
If streamlined end cap structure is used, then seamless splicing and dust prevention are achieved, but manufacturing complexity increases
Solution Approach 1:
The end cap is formed as a streamlined curved structure using injection molding or similar plastic forming processes. These manufacturing methods can efficiently produce complex curved geometries in a single operation, making the streamlined design economically viable despite its complexity, while achieving seamless splicing and dust prevention benefits.

AI summary
A luminaire with seamless splicing function includes a first lamp body and an end cap. The first lamp body has two joining portions disposed at the two sides thereof respectively. The end cap is combined with one of the joining portions and is a streamlined structure. The end cap has a curved side tip, a curved bottom tip and two side walls. The two sides walls are disposed at the two sides of the curved side tip and extend to the curved bottom tip. The two side walls are curved, and the curved side tip, the curved bottom tip and the two side walls are integrally formed. The streamlined structure of the end cap makes the shape thereof smooth in order to facilitate the smooth flow of air in cleanrooms and eliminate dust.
