Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a mechanical positioning mechanism with camera and image processing algorithm is used to position the viewer, then the viewer positioning accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent replaces the mechanical positioning mechanism with a software-based solution using the device's existing camera and screen. Instead of physically adjusting the display or viewer position with motors and sensors, the system uses image processing algorithms to analyze the captured image and provide visual feedback for positioning. This substitutes complex mechanical systems with software-based measurement and control.
Solution Approach 2:
The patent utilizes the device's own built-in camera and screen to perform the positioning function, rather than requiring external specialized equipment. The smartphone or tablet uses its existing components (camera for image capture, screen for displaying feedback) to enable self-positioning, making the device self-sufficient for this function without adding external specialized hardware.
2Adaptability or versatility
If specialized mechanisms are added to the display device for viewer positioning, then the viewer positioning capability is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The patent makes the existing camera and screen serve multiple functions: the camera is used both for its primary purpose (photography/video) and for viewer positioning detection, while the screen serves both as the display and as the reference object for positioning analysis. This multi-functionality adds viewer positioning capability without requiring specialized components, maintaining ease of manufacture.
Solution Approach 2:
The display device uses its own built-in camera and screen to enable viewer positioning, eliminating the need for external specialized mechanisms. By leveraging existing components already present in smartphones and tablets, the solution maintains manufacturing simplicity while adding adaptive positioning capability.
3Manufacturing precision
If external specialized equipment is used for viewer alignment, then the image uniformity and resolution are improved, but the ease of operation deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the system captures an image of the screen, analyzes the viewer's position relative to the optimal viewing angle, and displays visual feedback (such as alignment indicators or directional cues) on the screen. This feedback loop guides the user to adjust their position until optimal alignment is achieved, improving ease of operation through intuitive visual guidance rather than requiring complex manual adjustments.
Solution Approach 2:
The patent replaces complex mechanical positioning systems with a software-based visual feedback system. Instead of using motors, sensors, or mechanical actuators to physically position the viewer, the system uses image processing and visual cues displayed on the screen to guide the user's self-positioning, significantly simplifying the operation.
