Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surveying systems are unable to safely and accurately place staking tools on slopes due to the risk of the surveying device falling, as they are designed for horizontal planes and cannot be securely fixed on slopes, making it dangerous to operate.
Innovation Solution
A surveying system comprising a terminal device with a screen unit and a surveying device that includes design information acquisition, current slope estimation, first intersection calculation, and second intersection calculation units to assist in placing staking tools on slopes by calculating and displaying the necessary coordinates and altitude differences, allowing for safe and accurate placement without requiring the surveying device to be placed on the slope.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the surveying device is placed on a slope to survey staking tools, then the staking tool can be placed in a slope, but the surveying device may fall down which is dangerous
Solution Approach 1:
The patent introduces an intermediary calculation process that mediates between the surveying device on horizontal ground and the staking tool on the slope. By calculating the relationship between horizontal coordinates and slope coordinates through mathematical transformation, the system enables indirect surveying without requiring the surveying device to be physically placed on the unstable slope surface.
2Reliability
If the surveying device is placed on a horizontal plane, then the surveying device can be securely fixed, but it cannot directly survey staking tools placed on slopes
Solution Approach 1:
The patent transforms the surveying problem from direct three-dimensional slope measurement to a two-dimensional horizontal plane measurement with mathematical coordinate transformation. By projecting the slope surveying problem onto the horizontal plane and using coordinate system transformation, the system maintains surveying accuracy while ensuring device stability.
3Device complexity
If traditional surveying methods are used for slope staking, then simple equipment can be used, but accurate calculation of intersection coordinates and altitude differences is difficult
Solution Approach 1:
The patent replaces complex mechanical slope measurement equipment with a computational approach using standard surveying devices combined with mathematical calculations. By substituting mechanical complexity with algorithmic processing for coordinate transformation and intersection calculation, the system achieves high measurement precision while keeping the physical equipment simple and familiar.
