Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a conventional optical member is used with multiple light sources, then the light distribution becomes suboptimal and illuminance varies, but designing a custom optical member for each light source arrangement increases device complexity
Solution Approach 1:
The optical member is divided into multiple independent light controllers, where each light controller corresponds to and optically controls a specific light source. This segmentation allows each light source to be independently optimized for its position while maintaining overall system simplicity through modular design.
Solution Approach 2:
Each light controller is designed with specific optical characteristics tailored to its position and the corresponding light source. The light controllers have different shapes, sizes, and optical properties optimized for their local requirements, enabling uniform light distribution across the entire array while avoiding the need for a completely custom-designed optical member.
2Area of stationary object
If light sources are arranged in a matrix on the substrate, then the light distribution coverage is improved, but the illuminance uniformity deteriorates without corresponding optical control
Solution Approach 1:
The optical member is segmented into multiple light controllers corresponding to each light source in the matrix arrangement. Each light controller independently optimizes the light path for its associated light source, compensating for position-specific variations and ensuring uniform illuminance across the entire light coverage area.
Solution Approach 2:
Each light controller is designed with local optical characteristics optimized for its specific position in the matrix. The light controllers vary in shape, size, and optical properties according to their location, enabling uniform light distribution across different regions of the light coverage area.
