Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a display with invisible holes and light-resistant material is used, then high resolution image display is achieved, but the functionality for receiving and processing external information is limited
Solution Approach 1:
The display device is designed to perform multiple functions: it can display images through invisible holes, scan objects using optical sensors, detect touch inputs, and process biometric data. The same physical structure (display panel with sensors) supports both display and sensing functions, making the device universal and adaptable to various applications.
Solution Approach 2:
The patent combines the display function and sensing function into a single integrated device. Optical sensors, touch sensors, and light sources are embedded within the display panel structure, allowing the device to simultaneously or alternatively perform image display, object scanning, and input detection without requiring separate components.
2Adaptability or versatility
If multiple sensors and light sources are added to enhance functionality, then scanning and biometric capabilities are improved, but power consumption increases
Solution Approach 1:
The optical sensors and light sources operate periodically rather than continuously. The display can switch between display mode and scanning mode, activating sensors and light sources only when scanning or touch detection is needed, thereby reducing overall power consumption while maintaining enhanced functionality.
Solution Approach 2:
The display device uses its own light sources to illuminate objects for scanning, eliminating the need for separate external lighting systems. This self-service approach reduces the number of additional power-consuming components needed while achieving enhanced scanning and sensing capabilities.
3Manufacturing precision
If optical paths with small diameter holes are used, then image resolution is enhanced, but the ability to receive external optical signals is reduced
Solution Approach 1:
The display panel has different optical properties in different regions: the areas with invisible holes have precise optical paths for high-resolution image display, while the solid light-resistant material regions allow optical signals to pass through to the sensors. This local differentiation enables both high resolution display and effective optical signal reception without compromising either function.
