Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an input device is designed for a specific mode (e.g., mouse on desktop, capacitive digital pen on touchscreen), then the device can provide precise control for that mode, but the device cannot provide multiple use modes leading to poor user experience
Solution Approach 1:
The input device is designed to perform multiple functions by detecting different contact surfaces. It can function as a capacitive touch pen when contacting a touchscreen, as an electromagnetic pen when contacting an electromagnetic display, and as an optical mouse when contacting a general object surface. This multi-functionality resolves the contradiction by enabling a single device to adapt to various modes without requiring separate specialized devices.
Solution Approach 2:
The input device dynamically switches between different operating modes based on the detected contact surface type. The device determines whether it is contacting a touch apparatus or an object surface beyond the touch apparatus, and automatically adjusts its detection and control methods accordingly. This dynamic adaptation allows the device to maintain precision in each mode while providing versatility across modes.
2Adaptability or versatility
If an input device uses multiple detection methods (capacitive, electromagnetic, optical) to support multiple modes, then the device can adapt to different scenarios, but the detection and control complexity increases
Solution Approach 1:
The input device performs preliminary detection to determine the contact surface type before executing the appropriate control function. By first detecting whether the contact surface is a touch apparatus or an object surface beyond the touch apparatus, the device can then select and execute the corresponding detection and control method. This preliminary action simplifies the overall detection process by avoiding the need to simultaneously process all detection methods in all scenarios.
Solution Approach 2:
The input device uses feedback from the contact surface detection to adjust its operating mode. The electronic device provides feedback about the type of surface contacted, and the input device uses this feedback to determine the appropriate detection method and control function to employ. This feedback mechanism simplifies the detection process by enabling the device to focus on the relevant detection method for the current scenario.
