Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The sequential architecture of perception-planning-control in smart construction machines, such as excavators and loaders, often leads to poor coordination during complex operations due to the movement of sensors and working mechanisms, which can block the visual field or disrupt the perception of the environment.
Innovation Solution
A control system comprising an environment perception module, decision-making planning module, and control performing module that adjusts the perception module's state based on feedback and prediction to improve coordination by dynamically changing sensor parameters and motion trajectories.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the construction machine performs complex operations with moving sensors and working mechanisms, then the operation capability and productivity are improved, but the coordination deteriorates due to blocked visual field or disrupted environment perception
Solution Approach 1:
The patent applies dynamics by making the sensor positions and perception parameters adjustable and changeable during operation. The system dynamically adjusts sensor positions and perception parameters based on real-time operation states to maintain reliable environment perception while performing complex operations, resolving the contradiction between operation capability and coordination reliability.
2Adaptability or versatility
If the sensors and working mechanisms move during operation, then the versatility and adaptability are improved, but the measurement precision deteriorates due to blocked visual field or disrupted perception
Solution Approach 1:
The system implements feedback by continuously monitoring the operation state and environment perception quality, then adjusting sensor positions and perception parameters accordingly. This closed-loop control ensures that measurement precision is maintained even as the system adapts to different operation modes and complex tasks.
Solution Approach 2:
The patent makes the perception system dynamic by allowing real-time adjustment of sensor positions and parameters based on operation needs, enabling the system to maintain high measurement precision across various operation scenarios while preserving versatility.
3Reliability
If the system adjusts sensor parameters and motion trajectories in real-time, then the coordination and safety are improved, but the device complexity increases
Solution Approach 1:
The control system is designed with multi-functionality, integrating operations management, trajectory planning, and sensor parameter adjustment into a unified system. This universal approach allows the system to handle multiple functions through a single integrated control architecture, reducing overall complexity while maintaining high coordination and safety standards.
