Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate measuring devices are used for length and girth, then measurement accuracy is improved, but device complexity and time consumption increase
Solution Approach 1:
The patent combines the length measurer and girth measurer into a single integrated measuring system. The length measurer (tape measure) and girth measurer (circular measuring device with strap) are merged into one unit that can perform both functions, reducing the number of separate devices needed while maintaining measurement accuracy for both length and girth
Solution Approach 2:
The measuring system is designed with multi-functionality to measure both the length and girth of fish using a single device. The system includes a length measurer for measuring the overall length and a girth measurer with a circular guide and strap for measuring the girth, allowing one device to perform multiple measurement tasks that previously required separate tools
2Measurement precision
If multiple separate measuring devices are used, then measurement accuracy is improved, but the time required for measurement increases
Solution Approach 1:
By merging the length and girth measuring functions into a single integrated system, the patent eliminates the need to switch between separate devices during measurement. The user can measure both length and girth of a fish in one continuous operation, significantly reducing the time required compared to using separate measuring tools
Solution Approach 2:
The multi-functional design allows the single measuring system to perform both length and girth measurements without requiring the user to retrieve or switch between different devices. The integrated nature of the system enables rapid sequential measurement of both parameters, reducing total measurement time while maintaining accuracy
3Device complexity
If traditional separate measuring tools are used, then device simplicity is maintained, but measurement safety and accuracy deteriorate
Solution Approach 1:
The patent integrates safety features directly into the measuring system by combining the length measurer and girth measurer in a coordinated manner. The triangular guide structure and strap mechanism work together to provide stable, safe measurements without requiring complex additional safety devices, maintaining relative simplicity while improving reliability

AI summary
A girth measurer includes a generally tubular elongated body with interior and exterior ends. The girth measurer includes a handle at the interior end. The girth measurer also includes a generally triangular guide at the exterior end. The guide has two upper slots and two lower slots. A slider is reciprocally mounted for movement within the body. A strap is fabricated of a flexible, inextensible material. The strap has first and second ends passing downwardly through the slots and attached to the slider. The strap is in two parallel sections between the triangular guide and the handle. The strap is in a closed loop between the two upper slots. The loop is of varying circumferences as a function of the position of the handle along the body.
