Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If heavy blocks are used to simulate load during detection, then load simulation is achieved, but manual handling becomes labor-intensive and time-consuming
Solution Approach 1:
The patent uses a hydraulic lifting mechanism with a hydraulic cylinder to automatically lift and position the water container, replacing manual handling of heavy blocks. The hydraulic system provides precise control over load positioning while eliminating the need for manual intervention, thus resolving the contradiction between reliable load simulation and time-consuming manual operations.
Solution Approach 2:
The patent changes the state of the simulation medium from solid heavy blocks to liquid water in a container. This parameter change allows the load to be easily adjusted by adding or removing water, and the container can be automatically positioned using the hydraulic lifting mechanism, thereby reducing manual handling time while maintaining load simulation accuracy.
2Ease of operation
If the elevator compartment tilts within allowable range, then detection can proceed, but data accuracy deteriorates
Solution Approach 1:
The patent employs an inclination sensor to detect the tilt angle of the elevator compartment in real-time. When the tilt exceeds the allowable range, the system automatically triggers the hydraulic lifting mechanism to adjust the water container's position, thereby correcting the tilt and ensuring data accuracy is maintained while allowing flexible operation within safe parameters.
Solution Approach 2:
The system proactively monitors the elevator compartment's tilt angle before data collection begins. If tilting is detected within the allowable range, the system preemptively adjusts the water container position to compensate for potential tilt effects, ensuring data accuracy is preserved while maintaining operational flexibility.
3Device complexity
If only data recording is provided, then data collection is simple, but intuitive display of operating waveform parameters is lacking
Solution Approach 1:
The patent introduces a display module as an intermediary between the data acquisition system and the user. This module converts raw sensor data into intuitive waveform visualizations, allowing operators to easily interpret operating parameters without increasing the fundamental simplicity of the data collection mechanism. The display acts as a bridge that preserves system simplicity while eliminating information loss.
4Reliability
If manual observation and recording is required, then equipment operation state can be monitored, but detection efficiency decreases
Solution Approach 1:
The patent implements an automated detection system where sensors automatically monitor equipment operation states and the system self-records data without requiring manual observation. The hydraulic lifting mechanism also operates autonomously to position the water container based on tilt sensor feedback, thereby maintaining reliable monitoring while dramatically improving detection efficiency by eliminating manual intervention.
