Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a slope staking tool is placed at various positions with various positional relationships with a slope, then the system can handle diverse construction scenarios, but it becomes difficult for unexperienced operators to determine the correct position or orientation of the slope beam
Solution Approach 1:
The patent introduces a terminal device as an intermediary between the surveying device and the operator. This terminal device receives surveying information from the surveying device, calculates the correct stake shape based on the current ground state and designed slope, and provides guidance to the operator. This mediator eliminates the need for operators to manually determine complex positional relationships, thus maintaining adaptability while improving ease of operation.
Solution Approach 2:
The patent replaces the manual mechanical determination process with an automated information processing system. Instead of relying on operators' expertise to visually and manually determine stake placement, the system uses the surveying device to capture ground data, processes this data through calculation units, and automatically determines the correct stake shape and placement, substituting human judgment with automated computational methods.
2Measurement precision
If skilled operators manually determine stake placement based on experience, then accuracy can be maintained, but labor shortage and aging workforce reduce the availability of skilled operators
Solution Approach 1:
The patent enables the system to determine stake placement autonomously without requiring skilled operators. The surveying device automatically captures ground surveying information, the terminal device calculates the intersection between the current ground and designed slope, and the system determines the appropriate stake shape and placement. This self-service capability maintains placement accuracy while eliminating dependence on skilled operators, thus resolving the productivity issue caused by labor shortage and aging workforce.
Solution Approach 2:
The patent performs preliminary calculation of the stake shape and placement position before actual stake installation. The system calculates the intersection coordinate between the current ground and designed slope in advance, determines the required stake shape beforehand, and provides this information to the operator. This preliminary action ensures accuracy is maintained while reducing the need for skilled operators during the actual installation process.
3Measurement precision
If complex calculations are performed to determine stake shape and position, then accuracy improves, but the system complexity increases
Solution Approach 1:
The patent merges the surveying function and calculation function into an integrated system. The surveying device collects ground data, and the terminal device performs all necessary calculations including determining the intersection coordinate between current ground and designed slope, calculating stake placement position, and determining stake shape. By combining these functions in a unified system rather than separate complex devices, the patent achieves high measurement precision while managing system complexity through functional integration.
