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 trouble and discomfort
Solution Approach 1:
The patent extracts and eliminates the requirement for 3D glasses from the system by implementing a naked-eye 3D displaying device. The grating regulating device directly controls light transmission to achieve 3D effects without requiring additional wearable components, thus removing the source of user discomfort while maintaining the 3D displaying effect.
Solution Approach 2:
The patent introduces a grating regulating device as an intermediary component between the display and the user's eye. This device dynamically adjusts light transmission patterns to create 3D imaging effects, serving as a mediator that enables naked-eye 3D viewing without requiring the user to wear specialized glasses.
2Ease of operation
If naked-eye 3D displaying devices are used, then user convenience is improved, but interference issues occur due to slight user movements causing nausea and dizziness
Solution Approach 1:
The patent employs a dynamic grating regulating device that can real-time adjust light transmission patterns in response to user movement. The device dynamically modifies the grating structure's transmission characteristics to compensate for changes in viewing position, maintaining stable 3D imaging effects even when users move slightly, thereby eliminating nausea and dizziness caused by fixed grating patterns.
Solution Approach 2:
The patent implements a feedback mechanism where the grating regulating device detects user movement and automatically adjusts light transmission patterns accordingly. This closed-loop control system continuously monitors viewing conditions and modifies the grating's transmission characteristics to maintain optimal 3D imaging, preventing interference and discomfort caused by static grating patterns.
3Device complexity
If sub-electrodes in the same grating unit are connected to the same driving line, then device complexity is reduced, but precision of light-transmitting and opaque position control deteriorates
Solution Approach 1:
The patent segments the grating unit into multiple independently controllable sub-electrode regions. Each sub-electrode or group of sub-electrodes is connected to separate driving lines, allowing independent control of light transmission in different zones. This segmentation enables precise control of light-transmitting and opaque positions while maintaining manageable device complexity through modular architecture.
Solution Approach 2:
The patent applies local quality control by assigning different driving lines to different sub-electrode regions within the same grating unit. This allows each region to have customized control characteristics, enabling precise adjustment of light transmission patterns in specific areas while maintaining overall system functionality. The local differentiation of driving line connections achieves fine-grained control of optical properties.
