Monopod Surveying Instrument for Stable Measurement and Easy Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surveying instruments face challenges in installation complexity, requiring skilled labor and time, and stability issues during measurement, especially when equipped with high-capacity batteries or sophisticated processing systems, which complicates transfer and measurement accuracy.
Innovation Solution
A surveying instrument design featuring a monopod with a reference plate, ferrule, and wheels, equipped with longitudinal and lateral rotation detectors, rotation meters, and a time-measuring system, allowing for stable attitude maintenance and easy transfer, even with increased weight, by converting rotation angles into angles and associating them with movement distance and direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a tripod is used to install the surveying instrument, then the instrument can be horizontally leveled and positioned accurately, but the installation becomes complicated and time-consuming
Solution Approach 1:
The patent extracts the leveling and positioning functions from the traditional tripod setup. The monopod eliminates the need for complex tripod assembly and horizontal leveling by using a simplified single-leg structure with automatic positioning capabilities, keeping only the essential support function while removing unnecessary complexity.
Solution Approach 2:
The surveying instrument main body incorporates self-leveling and self-positioning functions through integrated sensors and automated adjustment mechanisms. The system automatically levels itself and positions the machine center over the reference point without requiring manual intervention or complex setup procedures.
2Ease of operation
If the surveying instrument is mounted on a monopod, then the installation becomes easy and transfer is simplified, but the stability during measurement decreases
Solution Approach 1:
The patent replaces the mechanical stability provided by a tripod's three-leg structure with an automated control system. Sensors detect the instrument's attitude and position, and motors automatically adjust the monopod and instrument main body to maintain stability and accuracy during measurement, substituting passive mechanical stability with active electronic control.
3Adaptability or versatility
If high-capacity battery and sophisticated processing system are mounted in the surveying instrument main body, then the functionality is improved, but the weight increases making transfer difficult
Solution Approach 1:
The patent uses the monopod's telescopic structure and adjustable length to counterbalance the weight of the instrument main body. The operator can adjust the monopod length to achieve optimal balance, reducing the effort required to hold and transfer the instrument despite its increased weight from high-capacity battery and processing system.
4Ease of operation
If the surveying instrument main body is provided on the monopod, then the transfer becomes easy, but the hand cannot be released from the instrument during measurement
Solution Approach 1:
The patent replaces manual holding and stabilization with an automated control system. Motors and sensors automatically maintain the instrument's position and attitude during measurement, freeing the operator's hands from the need to physically support the instrument while keeping it stable and accurate.
