Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate sensor devices and tensioning devices are used for monitoring and adjusting belt tension, then measurement precision can be achieved, but device complexity and cost increase significantly
Solution Approach 1:
The patent combines the sensor device and belt tensioning device into a single integrated unit. The sensor is arranged along the longitudinal direction of the belt at one end, merging the monitoring and adjustment functions into one device, thereby reducing overall system complexity while maintaining measurement precision.
Solution Approach 2:
The integrated device performs multiple functions simultaneously: it monitors belt tension through the sensor arranged longitudinally and adjusts tension through the built-in tensioning mechanism. This multi-functional design eliminates the need for separate devices, reducing complexity while preserving both measurement and adjustment capabilities.
2Measurement precision
If separate sensor devices and tensioning devices are used for belt tension monitoring and adjustment, then measurement capability is maintained, but cost increases
Solution Approach 1:
By merging the sensor device and belt tensioning device into a single integrated unit, the patent reduces the total number of components that need to be manufactured and assembled. This consolidation lowers manufacturing costs while preserving the measurement capability through the longitudinally arranged sensor.
3Device complexity
If belt tension is not monitored during operation, then device complexity is reduced, but reliability and safety decrease due to unexpected belt failures
Solution Approach 1:
The integrated device combines monitoring and tensioning functions in one unit, reducing complexity while enabling continuous belt tension monitoring during operation. The sensor arranged along the longitudinal direction provides real-time data, improving reliability without requiring multiple separate devices.
Solution Approach 2:
The sensor device provides continuous feedback on belt tension during operation, allowing the system to detect abnormal conditions and prevent belt failures. This feedback mechanism improves reliability while the integrated design keeps overall device complexity manageable.
4Reliability
If complex monitoring systems with multiple separate devices are used, then comprehensive monitoring is achieved, but ease of operation decreases
Solution Approach 1:
By combining the sensor device and belt tensioning device into a single integrated unit, the patent simplifies operation. The user interacts with one device for both monitoring and adjustment, improving ease of operation while maintaining comprehensive belt tension monitoring capability.
