Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the input device uses conventional vibration feedback without considering the moving body environment, then the device structure remains simple, but the vibration feedback becomes inappropriate in moving environments
Solution Approach 1:
The patent merges the input device with the moving body's existing sensor system by having the acquisition unit acquire traveling state information from sensors already installed in the vehicle (acceleration sensors, gyro sensors, etc.). This integration allows the vibration feedback to adapt to moving environments without adding separate sensing systems, thus improving adaptability while controlling structural complexity.
Solution Approach 2:
The vibration element's operating characteristics are made dynamic by adjusting its vibration strength based on real-time traveling state information. The element controller dynamically modifies the vibration parameters according to the moving body's acceleration, deceleration, and turning states, enabling the feedback mechanism to adapt continuously to changing environmental conditions.
2Measurement precision
If the vibration strength is increased to overcome moving body vibrations, then vibration detection improves, but energy consumption increases
Solution Approach 1:
Instead of continuously operating at maximum vibration strength, the system applies vibration selectively based on the traveling state. The element controller adjusts the vibration strength to be partially excessive only when needed (during acceleration, deceleration, or turning), and reduces or stops vibration when the vehicle is stationary or moving smoothly, thereby improving detection precision during critical moments while minimizing overall energy consumption.
Solution Approach 2:
The system changes the vibration parameter (strength) dynamically based on the traveling state information. By modifying the vibration strength parameter in response to acceleration, deceleration, and turning conditions, the system achieves adequate detection precision only when environmental vibrations interfere with input detection, rather than maintaining high vibration strength continuously, thus reducing energy consumption.
3Adaptability or versatility
If the vibration element operates at fixed strength, then the control system remains simple, but appropriate vibration feedback cannot be provided in varying traveling conditions
Solution Approach 1:
The element controller serves multiple functions: it not only controls the vibration element but also integrates information from various traveling state sensors (acceleration sensors, gyro sensors) and adjusts vibration parameters accordingly. This multi-functionality allows the control system to adapt to varying traveling conditions without requiring separate control mechanisms for each function, thereby improving vibration feedback appropriateness while managing control system complexity.
