Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed distance between display panel and three-dimensional optical panel is used, then the system structure is simple, but crosstalk occurs and visual fatigue is caused due to improper disparity for different user positions
Solution Approach 1:
The patent applies the dynamics principle by making the distance between the display panel and three-dimensional optical panel adjustable rather than fixed. The driving unit dynamically changes this distance based on user position detection, allowing the system to adapt to different viewing distances and reduce crosstalk while maintaining user comfort without requiring complex structural modifications.
Solution Approach 2:
The patent implements feedback by using the position detection unit to continuously monitor user position and feed this information back to the driving unit. This feedback loop enables the system to automatically adjust the optical panel position to optimize disparity and minimize crosstalk according to the actual user viewing position.
2Manufacturing precision
If delicate slit motion control is implemented to provide proper disparity, then three-dimensional image quality is improved, but the system becomes difficult to realize and control
Solution Approach 1:
The patent replaces complex mechanical slit motion control with an optical approach. Instead of mechanically moving slits with delicate precision, the system uses a three-dimensional optical panel that can be positioned at different distances from the display panel. This substitution of mechanical control with optical positioning simplifies the control mechanism while achieving the desired disparity effect.
Solution Approach 2:
The patent applies parameter changes by adjusting the distance parameter between the display panel and three-dimensional optical panel based on user position. This single parameter adjustment (distance) enables the system to provide proper disparity without requiring complex motion control of slits, thereby reducing control difficulty while maintaining manufacturing precision.
3Reliability
If three-dimensional glasses are used to view three-dimensional images, then image depth is achieved, but visual fatigue and inconvenience occur
Solution Approach 1:
The patent extracts and eliminates the need for three-dimensional glasses from the system. By using a three-dimensional optical panel that directly converts two-dimensional images into three-dimensional images without requiring additional glasses, the system achieves image depth while removing the source of visual fatigue and inconvenience associated with wearing glasses.
Solution Approach 2:
The patent introduces a three-dimensional optical panel as an intermediary between the display panel and the user's eyes. This optical panel performs the function of creating three-dimensional image depth without requiring the user to wear additional glasses, thereby maintaining image quality while improving user convenience.
