Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current large-scale workshop measuring and positioning systems face inefficiencies due to external vibrations and creep deformations affecting transmitter orientation parameters, requiring frequent recalibrations that are labor-intensive and inefficient.

Engineering Contradiction Analysis
1Area of stationary object
If transmitters are arranged in the measurement system to establish a large-scale measurement network, then measurement range and coverage are improved, but transmitters are more susceptible to external vibration and creep deformation affecting orientation parameters
Solution Approach 1:
The patent introduces an inclinometer as an intermediary device to detect and measure the attitude changes of transmitters. The inclinometer serves as a mediator between the transmitter and the measurement system, providing real-time data about orientation deviations caused by vibrations or creep, which then can be compensated through coordinate transformation.
Solution Approach 2:
The system implements a feedback mechanism where the inclinometer continuously monitors transmitter attitude, and the measured orientation parameters are fed back to update the transmitter coordinate systems in real-time. This closed-loop feedback enables dynamic compensation of orientation deviations without requiring manual recalibration.
2Measurement precision
If recalibration is performed periodically to correct transmitter orientation parameters, then measurement accuracy is improved, but large amounts of repeated manual operations are required reducing efficiency
Solution Approach 1:
The system achieves self-service calibration by automatically detecting transmitter attitude changes using inclinometers and performing real-time coordinate transformations. The measurement system calibrates itself continuously without requiring external intervention or manual recalibration operations, thereby maintaining high accuracy while eliminating time-consuming manual procedures.
Solution Approach 2:
Instead of periodic discrete recalibration events, the system implements continuous orientation parameter compensation through real-time inclinometer monitoring and dynamic coordinate updates. This continuous action ensures measurement accuracy is maintained constantly without interruption or repeated manual operations.
3Reliability
If inclinometer-combined transmitters are used with real-time attitude compensation, then system stability in harsh environments is improved, but device complexity increases due to additional sensors and calibration procedures
Solution Approach 1:
The patent merges the inclinometer with the transmitter into an integrated unit, combining attitude detection and measurement transmission functions. This merging reduces the number of separate components and simplifies the overall system architecture while maintaining the ability to compensate for orientation changes in harsh environments.
Solution Approach 2:
The inclinometer-combined transmitter serves multiple functions: it performs both the original measurement transmission role and the additional attitude detection role. This multi-functionality reduces the need for separate dedicated attitude sensors and simplifies the system by having one component perform multiple tasks.
