Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If switching between position and gesture detection modes is implemented using existing techniques, then both detection functions can be provided, but device complexity increases and operation becomes cumbersome due to requiring tilt changes and time-sharing
Solution Approach 1:
The detection space is segmented into two distinct zones: a first detection area for position detection and a second detection area for gesture detection. This spatial segmentation allows the system to handle different detection types simultaneously without mode switching, eliminating the complexity of tilt-based mode changes while maintaining both detection functions.
Solution Approach 2:
The patent introduces a spatial dimension solution by creating separate detection zones in different locations. Instead of using temporal multiplexing (time-sharing) or orientational changes (tilt), the system uses spatial separation to distinguish between position detection and gesture detection modes, simplifying the user interface while maintaining versatility.
2Adaptability or versatility
If time-sharing between touch sensor display and contactless detection section is used, then both detection functions can operate, but time resolution of each detection function lowers
Solution Approach 1:
The detection system is segmented into spatially separate zones that operate simultaneously and independently. The first detection area processes position detection while the second detection area processes gesture detection, eliminating the need for time-sharing and restoring full time resolution to both detection functions.
Solution Approach 2:
Instead of using temporal multiplexing to share detection resources, the patent uses spatial separation to provide dedicated detection zones. This dimensional approach allows both detection functions to operate at full resolution simultaneously without interfering with each other.
3Adaptability or versatility
If function selection is done through menu or icons on display screen, then various functions can be accessed, but operation becomes cumbersome and time-consuming
Solution Approach 1:
The system enables self-service operation by automatically recognizing gestures performed in the second detection area and directly executing corresponding functions. Users perform gestures naturally in the air, and the system automatically interprets and executes the intended function without requiring users to navigate menus or tap icons, significantly improving operational convenience while maintaining function variety.
Solution Approach 2:
The patent replaces the mechanical interaction system of button presses and icon tapping with gesture-based interaction. By using motion sensors to detect gestures in the second detection area, the system substitutes manual interface operations with more intuitive and efficient gesture recognition, reducing the steps required to activate functions.
