Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional LED lighting apparatuses are used, then high conversion efficiency and long life span are achieved, but intense light is emitted that can be harsh on the eyes
Solution Approach 1:
The lighting apparatus is divided into multiple light sources arranged in a specific pattern, with each light source contributing to the overall illumination. This segmentation allows the light to be distributed more evenly and reduces the intensity from any single point, mitigating eye strain while maintaining total luminous output
Solution Approach 2:
A reflector is introduced as an intermediary element between the light sources and the viewing area. The reflector redirects and diffuses the light from the LEDs, transforming the direct intense light into a more distributed and less harsh illumination pattern that reduces eye strain
2Object-affected harmful factors
If a reflector with multiple reflective surfaces is used, then light is effectively redirected and eye strain is reduced, but device complexity increases
Solution Approach 1:
The reflector is integrated directly into the housing structure of the lighting apparatus, merging two separate components (reflector and housing) into a unified structure. This reduces the number of separate parts and simplifies assembly while maintaining the light-redistributing function
Solution Approach 2:
The housing structure serves multiple functions: it provides structural support, contains the light sources, and incorporates the reflector surface for light redirection. This multi-functionality reduces the need for additional dedicated components, simplifying the overall device structure
3Loss of energy
If light sources are disposed on side surfaces corresponding to reflective surfaces, then luminous efficiency is improved, but manufacturing precision requirements increase
Solution Approach 1:
The housing is pre-formed with integrated reflector surfaces and predetermined mounting locations for the light sources. This preliminary structuring ensures that when light sources are installed, they are automatically positioned at the optimal locations for maximum luminous efficiency, reducing the need for high-precision adjustment during assembly
Solution Approach 2:
The housing structure incorporates locally optimized features such as recesses, protrusions, or keyed interfaces at specific mounting locations that guide light source placement. These localized structural qualities ensure precise positioning without requiring high-precision manufacturing throughout the entire component
