Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing speed determination methods for controlled targets in automated systems, such as excavators, face challenges in accurately determining target speeds and directions, leading to inefficiencies and inaccuracies in control processes.
Innovation Solution
A method that determines the expected speed direction of a controlled point based on its actual location and preset trajectory, followed by calculating the target speed of controlled targets with a kinematic relationship, using equations and kinematic principles to adjust for time lags and deviations, thereby enabling precise control parameter determination and accurate target positioning.

Engineering Contradiction Analysis
1Measurement precision
If existing speed determination methods are used for controlled targets in automated systems, then the control process can be implemented, but the accuracy of determining target speeds and directions deteriorates
Solution Approach 1:
The patent segments the speed determination process into distinct components: determining expected speed direction from actual location and preset trajectory, then determining target speed separately using kinematic relationships. This segmentation allows each component to be optimized independently, improving overall accuracy.
Solution Approach 2:
The patent performs preliminary determination of expected speed direction before calculating target speed. By first establishing the expected direction based on trajectory and actual location, the system prepares a reference framework that guides the subsequent speed calculation, reducing errors in the final determination.
2Productivity
If existing speed determination methods are used, then control processes can proceed, but operational efficiency deteriorates due to inaccuracies requiring correction
Solution Approach 1:
The patent incorporates feedback by continuously comparing actual location with preset trajectory to determine expected speed direction, then using this information to calculate target speed. This closed-loop approach ensures accuracy while maintaining efficiency, as corrections are made proactively rather than reactively.
Solution Approach 2:
The patent dynamically adjusts speed parameters based on real-time conditions by calculating expected speed direction from current actual location and trajectory, then determining target speed through kinematic relationships. This parameter adaptation allows the system to maintain high operational efficiency across varying conditions without sacrificing accuracy.
