Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the relative distance between the stereoscopic display panel module and the observer changes, then the viewing flexibility is improved, but 3D crosstalk and pseudoscopic views occur leading to discomfort
Solution Approach 1:
The patent applies dynamics by making the display settings adjustable in real-time based on the observed distance. The display setting adjusting module dynamically modifies the stereoscopic image parameters according to the calculated distance between the display panel and the observer, allowing the system to adapt to changing viewing conditions while preventing 3D crosstalk and pseudoscopic views
Solution Approach 2:
The patent implements feedback through the relative distance calculation module that continuously determines the distance between the display panel and observer, and the display setting adjusting module that uses this information to automatically adjust display settings. This closed-loop feedback system ensures optimal stereoscopic display quality at various viewing distances
2Measurement precision
If expensive measuring devices are used to detect observing distance, then measurement precision is improved, but device cost increases
Solution Approach 1:
The patent employs inexpensive sensors such as acceleration sensors or tilt sensors to detect the inclination angle of the front seat, replacing expensive specialized measuring devices. These low-cost sensors provide sufficient measurement precision for calculating the observing distance by combining the inclination angle data with the known geometric relationship between the display device and observer
3Manufacturing precision
If complex algorithms are used to adjust display settings, then image quality is improved, but device complexity increases
Solution Approach 1:
The patent adjusts display settings by modifying parameters such as the stereoscopic image parallax, brightness, or contrast based on the calculated observing distance. The display setting adjusting module changes these parameters in a systematic manner according to distance ranges, providing high image quality through parameter optimization without requiring complex computational algorithms
