Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually select operation settings through application programs, then editing functions can be changed, but operation time increases and convenience decreases
Solution Approach 1:
The system automatically detects the dielectric parameter of the touch input device and executes the corresponding operating function without requiring user intervention. The electronic apparatus serves itself by autonomously identifying the input device type (stylus, finger, etc.) and applying the appropriate settings, thereby eliminating manual configuration steps and reducing operation time.
Solution Approach 2:
The system changes operating parameters (color, line thickness, editing functions) based on the detected dielectric parameter of the touch input device. By linking physical properties of the input device to operational settings, the system automatically adjusts parameters without requiring users to manually search through application menus, thus improving convenience and reducing time loss.
2Adaptability or versatility
If multiple touch input devices are supported, then operating versatility increases, but device complexity increases
Solution Approach 1:
The system replaces complex mechanical or manual identification methods with electrical field-based detection. By measuring the dielectric parameter (capacitive properties) of the touch input device, the system automatically identifies the device type without requiring manual selection or complex mechanical sensors, thus supporting multiple input devices while maintaining relatively simple system architecture.
Solution Approach 2:
The dielectric parameter serves as an intermediary that bridges the touch input device and the operating system. Instead of directly complex device identification and configuration, the system uses the dielectric parameter as a mediator to automatically determine the appropriate operating function, simplifying the interaction between diverse input devices and the system while maintaining high versatility.
