Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional peripheral devices are used, then device functionality is provided, but device complexity and portability are compromised
Solution Approach 1:
The patent applies universality by creating a single peripheral device that can perform multiple functions through software configuration. The system allows one physical device to adapt to different input device types (keyboard, mouse, trackball, etc.) by changing operational modes, eliminating the need for multiple specialized devices and reducing overall system complexity.
Solution Approach 2:
The patent implements dynamics by making the device characteristics adjustable and changeable during operation. The peripheral device can dynamically switch between different input device types and configurations based on user needs, allowing the same hardware to adapt its functionality rather than being fixed in a single state.
2Measurement precision
If specialized peripheral devices are created for specific functions, then functional precision is improved, but device portability and ease of operation deteriorate
Solution Approach 1:
The patent creates a universal peripheral device that can simulate multiple input device types, maintaining functional precision for each type while eliminating the need for users to carry or switch between multiple specialized devices. The single device provides mouse, keyboard, trackball, and other input functions through software control.
Solution Approach 2:
The patent changes operational parameters of the peripheral device through software configuration to simulate different input device characteristics. By adjusting parameters such as movement sensitivity, button mappings, and tracking algorithms, the device maintains precision for each simulated type while remaining a single portable unit.
3Adaptability or versatility
If multiple input devices are provided for different functions, then user interaction versatility is improved, but device complexity and transportability worsen
Solution Approach 1:
The patent merges multiple input device functions into a single peripheral device. By combining mouse tracking, keyboard input, trackball operation, and other input types into one unified device, the system achieves user interaction versatility without requiring users to manage multiple separate devices, thereby improving portability.
Solution Approach 2:
The universal peripheral device provides multiple input interaction modes through software configuration, allowing users to access diverse interaction types from a single device. This eliminates the need to transport multiple specialized input devices while maintaining full interaction versatility across different computing tasks.
