Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If image resolution is maintained at standard values (N*M pixels), then image quality is preserved, but refresh rate decreases during user motion
Solution Approach 1:
The patent implements dynamic resolution adjustment by monitoring user motion state and adapting image resolution in real-time. The system transitions from static standard resolution to dynamic resolution values that change based on motion detection, allowing the display to maintain high refresh rates during motion while preserving image quality during stationary periods.
Solution Approach 2:
The patent changes the resolution parameter (N*M pixels) based on motion state. When motion is detected, the system adjusts resolution parameters to lower values, enabling higher refresh rates. When stationary, parameters return to standard values for optimal image quality. This parameter adaptation resolves the contradiction between quality and speed.

If image resolution is reduced to maintain high refresh rate, then refresh rate increases, but image quality deteriorates
Solution Approach 1:
The system dynamically adjusts resolution based on motion state rather than using a fixed low resolution. During motion, resolution is reduced to maintain refresh rate; during stationary periods, resolution returns to standard values for optimal quality. This dynamic approach ensures quality is not permanently compromised.
Solution Approach 2:
The system periodically monitors motion state and adjusts resolution accordingly. This periodic adjustment between high resolution (stationary) and low resolution (motion) states ensures that image quality is maintained whenever possible, while refresh rate is optimized during motion periods.
3Manufacturing precision
If standard resolution (N*M pixels) is used for image generation, then image quality is maintained, but computational load increases
Solution Approach 1:
The patent implements dynamic computational load management by adjusting resolution based on motion state. During motion, computational load is reduced by using lower resolution values, enabling higher refresh rates. During stationary periods, full computational resources are used for standard resolution to maintain image quality.
Solution Approach 2:
The system changes the resolution parameter (N*M pixels) based on motion detection, directly affecting computational load. Lower resolution parameters during motion reduce processing requirements and power consumption, while standard parameters during stationary periods maintain quality without excessive load.
4Speed
If resolution is adjusted based on motion direction, then refresh rate is maintained, but system complexity increases
Solution Approach 1:
The patent adds motion detection and dynamic resolution adjustment capabilities to the display system. This dynamic component monitors motion direction and state, then adapts resolution parameters accordingly, maintaining refresh rate while adding only the necessary complexity for motion-based adaptation.
Solution Approach 2:
The system implements feedback through motion detection that informs resolution adjustment decisions. Motion state feedback triggers appropriate resolution changes, creating a closed-loop system that maintains refresh rate while using feedback-driven complexity only when motion is detected.
