Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple LEDs of different light types are arranged on a substrate, then display resolution and brightness uniformity are improved, but light displacement and imaging quality deteriorate without proper control
Solution Approach 1:
The patent applies local quality by differentiating the treatment of different light types (red, green, blue LEDs) through individual focusing optics with specific radii of curvature. Each color channel receives customized optical control to compensate for their different emission characteristics, thereby maintaining high display resolution while preventing light displacement and preserving imaging quality.
Solution Approach 2:
The patent utilizes parameter changes by adjusting the radius of curvature of focusing optics according to the specific light type. Different radii of curvature are assigned to red, green, and blue LEDs to optimize their respective light emission patterns, enabling precise control over light displacement and maintaining both display resolution and imaging quality simultaneously.
2Reliability
If focusing optics are added to control light emission, then light displacement is reduced and imaging quality improves, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the optical control system into individual focusing optics for each LED type rather than using a single complex optical system. This modular approach allows independent optimization of each color channel while keeping the overall structure manageable and reducing system complexity.
Solution Approach 2:
The patent employs spheroidality by using focusing optics with spherical surfaces characterized by specific radii of curvature. This geometric approach provides effective light control through simple curved surfaces, achieving improved imaging quality without requiring complex optical elements or multi-component systems.
3Ease of operation
If different radii of curvature are used for different light types, then light emission control is optimized and display uniformity improves, but manufacturing precision requirements increase
Solution Approach 1:
The patent applies preliminary action by pre-determining the optimal radius of curvature for each light type before manufacturing. These parameters are established in advance based on the optical characteristics of red, green, and blue LEDs, allowing the manufacturing process to follow predetermined specifications and reducing the actual alignment precision requirements during assembly.
