Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional 3D displaying devices require users to wear 3D glasses, then 3D displaying effect can be achieved, but user experience deteriorates due to inconvenience and discomfort
Solution Approach 1:
The patent extracts and eliminates the requirement for 3D glasses from the viewing system. By using a grating regulating device that dynamically adjusts light transmission patterns, the system achieves 3D displaying effect without requiring users to wear additional glasses, thus improving ease of operation while maintaining 3D displaying reliability
Solution Approach 2:
The patent employs a dynamic grating regulating device that can real-time adjust the light transmission characteristics of different regions. The device dynamically switches between light-transmitting and light-shielding states based on driving signals, enabling adaptive 3D display that works without 3D glasses by manipulating light paths in real-time
2Ease of operation
If naked-eye 3D displaying devices are used, then user convenience is improved, but interference occurs when users move, causing discomfort
Solution Approach 1:
The patent implements a feedback mechanism where the grating regulating device receives driving signals that respond to user position or movement conditions. The device adjusts the light transmission patterns dynamically based on feedback about user state, thereby maintaining stable 3D display效果 while compensating for user movement to reduce interference and discomfort
Solution Approach 2:
The patent uses a dynamic grating regulating device that real-time adjusts light transmission characteristics in response to user movement. The device transitions between light-transmitting and light-shielding states based on driving signals that adapt to changing viewing conditions, thereby maintaining display stability and reducing interference caused by user movement
3Object-affected harmful factors
If grating units are controlled independently to adjust positions and aperture ratios, then interference from user movement is reduced, but device complexity increases
Solution Approach 1:
The patent divides the display system into multiple independently controllable grating units, each capable of adjusting its position and aperture ratio separately. This segmentation allows different regions of the display to be optimized independently, reducing interference from user movement while managing complexity through modular control architecture
Solution Approach 2:
The patent applies local quality control by enabling each grating unit to have independent control over its light transmission characteristics. Different grating units can be controlled differently based on local requirements, allowing precise adjustment of aperture ratios and positions to minimize interference while maintaining overall system manageability through localized control
