Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current machine control systems lack the ability to accurately detect and position objects in 3D space, leading to potential collisions and inefficient operation, especially in complex work environments with multiple obstacles and varying object dimensions and weights.
Innovation Solution
A control system that utilizes sensing means to provide position and orientation data of tools and machines within a 3D work site space, allowing for adaptive operation modes based on object and obstacle detection, safety zones, and operator skill levels, with feedback mechanisms to prevent collisions and optimize handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional control systems are used without 3D object detection, then the system complexity is low, but collision prevention capability and operational safety deteriorate
Solution Approach 1:
A control unit acts as an intermediary between the detecting means (sensors, cameras, LIDAR) and the tool control system. The control unit processes 3D position and orientation data of objects and machine components, then generates appropriate control signals to prevent collisions and optimize tool operation, thereby resolving the contradiction between added detection complexity and improved safety
Solution Approach 2:
The system continuously detects the 3D positions of objects and machine components, feeds this information back to the control unit, which then adjusts tool operation in real-time. This closed-loop feedback mechanism enables dynamic collision prevention and operational optimization, transforming the static control system into an adaptive safety-oriented system
2Ease of operation
If 3D object detection and positioning is implemented, then operational safety and collision prevention improve, but the device complexity and cost increase
Solution Approach 1:
The detecting means and control unit serve multiple functions: they detect object positions, determine orientations, calculate safety zones, optimize tool paths, and prevent collisions. By making the detection system multi-functional, the patent reduces the need for separate specialized systems, thereby improving operational safety without proportionally increasing complexity
Solution Approach 2:
The system automatically detects objects, determines their positions and orientations, calculates appropriate safety zones, and adjusts tool operation without requiring manual intervention. This self-service capability enhances operational safety while reducing the complexity of manual monitoring and control systems
3Productivity
If adaptive operation modes are implemented based on object detection, then tool handling efficiency improves, but control system complexity increases
Solution Approach 1:
The control system dynamically adapts operation modes based on real-time detection data. The control unit adjusts tool speed, position, and orientation according to the detected object characteristics and calculated safety zones, enabling efficient and safe handling of diverse objects without requiring multiple fixed control systems
