Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional center-of-mass measuring device is used, then center of mass can be measured, but length cannot be measured simultaneously
Solution Approach 1:
The patent combines the length measurement function and center-of-mass measurement function into a single integrated device. The laser displacement sensor measures length while the weighing mechanisms measure center of mass, both within the same device structure, eliminating the need for separate measurement devices.
Solution Approach 2:
The measuring device is designed with multi-functionality to perform both length measurement and center-of-mass measurement. The frame structure supports both the laser displacement sensor for length measurement and the weighing mechanisms for center-of-mass measurement, making the device universal for multiple measurement tasks.
2Ease of operation
If separate devices are used for length and center of mass measurement, then measurement accuracy can be maintained, but operational simplicity deteriorates
Solution Approach 1:
The patent merges multiple measurement functions into one device while maintaining measurement precision through dedicated sensors and mechanisms for each function. The integrated design simplifies operation by allowing both measurements to be performed in sequence without moving the workpiece between different devices.
Solution Approach 2:
The device performs length measurement first using the laser displacement sensor before proceeding to center-of-mass measurement. This preliminary action sequence is built into the device operation, allowing operators to follow a straightforward measurement protocol without complex setup changes.
3Ease of operation
If multi-point weighing method is used, then center of mass measurement is simple and convenient, but length measurement capability is lost
Solution Approach 1:
The patent combines the multi-point weighing method for center-of-mass measurement with laser displacement sensing for length measurement. The weighing mechanisms maintain their simple multi-point operation while the added laser sensors provide length measurement capability without complicating the weighing process.
