Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the actuator is set to maximum power for rapid operation, then productivity is improved, but safety deteriorates due to increased collision energy
Solution Approach 1:
The actuator control system dynamically adjusts power delivery based on real-time feedback from force sensors and position encoders. The system transitions between high-power mode during normal operation and low-power mode when obstacles are detected, allowing rapid door operation while limiting collision energy through active power management
Solution Approach 2:
The system continuously monitors operational parameters including motor current, position, and force applied to the door. This feedback loop enables the control system to detect obstacle presence and automatically reduce power output to limit collision energy while maintaining rapid operation during normal conditions
2Object-affected harmful factors
If multiple sensors are installed to improve obstacle detection, then safety is improved, but device complexity and cost increase
Solution Approach 1:
The system uses a single multi-functional sensor assembly that combines force sensing, position detection, and obstacle detection capabilities. The force sensor serves multiple purposes: monitoring door operation forces, detecting obstacles, and providing feedback for power adjustment, eliminating the need for separate sensors for each function
Solution Approach 2:
The patent combines force sensing and position detection functions into a single integrated sensor system. The force sensor is strategically positioned to simultaneously measure operational forces and detect obstacle presence, while the position encoder provides both location information and obstacle detection, merging multiple safety functions into unified sensor elements
3Ease of operation
If manual adjustment of the potentiometer is performed by inexperienced users, then ease of operation is improved, but safety deteriorates due to incorrect settings
Solution Approach 1:
The system automatically performs the adjustment function that would otherwise require manual potentiometer tuning. The control system self-calibrates by monitoring force sensor data during door operation and automatically adjusts power delivery parameters to optimize safety, eliminating the need for user intervention and ensuring consistent reliable settings
Solution Approach 2:
The system uses feedback from force sensors and position encoders to automatically determine optimal power settings. During initial operation or after power loss, the system performs self-calibration by measuring actual door forces and adjusting control parameters accordingly, ensuring safe operation without requiring user knowledge or manual adjustment
