Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for controlling movable platforms like unmanned aerial vehicles and mechanical arms require manual adjustment of position and orientation, which is tedious and lacks accuracy, especially when operating on specific targets such as power insulators or fruits, as they require repeated adjustments of angles and distances.
Innovation Solution

Engineering Contradiction Analysis
1Productivity
If manual adjustment of position and orientation is used to control movable platforms, then the control method is simple to implement, but the operational efficiency is low and requires repeated adjustments
Solution Approach 1:
The system performs preliminary action by pre-calculating and determining the target position and orientation of the movable platform before actual operation. The control terminal calculates the optimal target position based on the current position, operation distance, and orientation parameters, allowing the platform to directly navigate to the predetermined position without requiring repeated manual adjustments during operation.
Solution Approach 2:
The patent replaces the manual mechanical adjustment system with an automated computational system. The control terminal uses calculation modules to automatically compute target positions and orientations based on input parameters, substituting the manual trial-and-error adjustment process with automated mathematical calculations and digital control signals.
2Measurement precision
If manual adjustment of angles and distances is used for fine control, then the control approach is straightforward, but the measurement precision and positioning accuracy are insufficient
Solution Approach 1:
The patent replaces manual visual estimation and mechanical adjustment with automated computational calculation. The control terminal calculates precise target positions using mathematical formulas that incorporate operation distances, orientation angles, and platform dimensions, achieving high positioning accuracy without requiring the operator to manually estimate or repeatedly adjust angles and distances.
Solution Approach 2:
The system creates a virtual representation or model of the operation scenario, where target positions and orientations are calculated based on digital parameters rather than physical trial-and-error. This virtual modeling approach allows for precise determination of platform positioning before actual movement, improving accuracy while simplifying the operational process.
3Loss of time
If repeated adjustments of angles and distances are performed, then the control flexibility is maintained, but the time consumption increases significantly
Solution Approach 1:
The system performs preliminary calculation of the target position and orientation before the platform begins movement. By pre-determining the optimal position based on current state and operation parameters, the system eliminates the need for time-consuming repeated adjustments during operation, significantly reducing time consumption while maintaining control flexibility through programmable parameter adjustments.
Solution Approach 2:
The system implements feedback by continuously monitoring the current position and orientation of the movable platform, then using this information to calculate and adjust target positions. This closed-loop approach ensures flexibility in adapting to different operational scenarios while minimizing time loss through efficient, calculation-based positioning rather than trial-and-error adjustments.
