Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a demonstration system is added to the active vibration isolation system, then user understanding and acceptance improve, but device complexity increases
Solution Approach 1:
The actuator is designed to perform multiple functions: during normal operation it provides vibration isolation forces, and during demonstration mode it reproduces vibration signatures for educational purposes. The processor similarly handles both real-time vibration control and demonstration sequence execution, eliminating the need for separate dedicated demonstration hardware.
Solution Approach 2:
The demonstration system merges with the existing active vibration isolation system by utilizing the same processor, actuator, and sensor infrastructure. The demonstration mode is integrated into the control algorithm, combining educational functionality with the primary vibration isolation function in a unified system architecture.
2Ease of operation
If demonstration mode is added to educate users, then user acceptance improves, but loss of time during switching between modes increases
Solution Approach 1:
The system pre-loads demonstration sequences and maintains readiness for mode switching. The processor keeps demonstration data and vibration signatures prepared in advance, allowing rapid transition between normal operation and demonstration modes without requiring time-consuming setup or configuration changes.
Solution Approach 2:
The system dynamically switches between normal operation mode and demonstration mode based on user input or system conditions. The control algorithm can seamlessly adjust its behavior in real-time, enabling the actuator to transition from providing vibration isolation forces to reproducing demonstration vibration signatures without mechanical reconfiguration or prolonged switching delays.
