Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If load reduction control is provided based on fixed operation modes, then the control system is simple, but it cannot adapt to varying user situations and environments
Solution Approach 1:
The patent implements dynamic operation mode transitions based on real-time detection of user situation changes. The control device automatically switches between operation modes (e.g., from first to second mode) when detection results indicate changed conditions, allowing the system to adapt to varying environments without requiring complex manual reconfiguration or overly sophisticated control architecture.
Solution Approach 2:
The system employs a detection device that continuously monitors user situations and provides feedback to the control device. This feedback mechanism enables the control device to adjust operation modes based on actual conditions, achieving adaptability through a relatively simple closed-loop control structure rather than complex predictive modeling.
2Reliability
If the powered suit operates in a fixed operation mode, then the device complexity is low, but the load reduction effectiveness decreases when user situation changes
Solution Approach 1:
The patent defines multiple operation modes with different control parameters tailored to specific user situations. The system dynamically selects the appropriate mode based on detection results, ensuring reliable load reduction effectiveness for each situation while maintaining relatively simple mode definitions that do not require complex control logic.
Solution Approach 2:
Different operation modes correspond to different control parameters optimized for specific conditions. The system changes these parameters automatically based on detected user situations, achieving reliable performance across varying conditions through parameter adjustment rather than complex control algorithms.
3Adaptability or versatility
If operation mode is manually changed by the user, then the system remains simple, but it cannot automatically adapt to environmental changes like weather and terrain
Solution Approach 1:
The detection device automatically monitors user situations and the control device autonomously determines and switches operation modes based on detection results. This self-service mechanism eliminates the need for manual user intervention while maintaining simple operation, as the system handles adaptation automatically without requiring complex user interfaces or decision-making algorithms.
Solution Approach 2:
The automatic detection and control system provides continuous feedback between the detection device and control device, enabling autonomous adaptation to environmental changes. This feedback loop achieves automatic adaptation while keeping the system simple, as it relies on direct detection-to-control signaling rather than complex processing or user interaction.
