Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine control systems lack the ability to accurately detect and position objects in 3D space, leading to potential collisions and inefficient operation, especially in dynamic work environments like construction sites where obstacles and varying object sizes and weights are present.
Innovation Solution
A control system that utilizes a combination of range finder devices, sensing means, and controllers to detect and position objects in 3D space, adjusting operation modes based on object dimensions, weight, safety zones, and surrounding obstacles, allowing for safe handling and movement of tools by machines like excavators and cranes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional control systems are used without 3D object detection, then the device complexity is low, but the reliability is poor due to potential collisions and inefficient operation
Solution Approach 1:
The range finder device detects and positions objects in 3D space before the machine tool approaches them, allowing the control system to pre-plan safe operation paths and adjust control modes in advance, preventing collisions before they occur
Solution Approach 2:
The control system acts as an intermediary between the machine operator and the actual tool operation, using 3D object detection data to automatically adjust control modes and intervene when potential collisions are detected, mediating between human intent and safe execution
2Measurement precision
If 3D object detection and positioning is implemented, then the measurement precision of object location is improved, but the device complexity increases due to additional range finder devices and sensing means
Solution Approach 1:
The control system is designed to handle multiple functions including 3D object detection, positioning, collision prevention, and adaptive control mode adjustment, allowing a single integrated system to perform what would otherwise require multiple separate systems
Solution Approach 2:
The range finder device and sensing means automatically detect and provide 3D position data without requiring manual measurement or operator input, making the detection system self-sufficient and reducing the need for additional operational complexity
3Adaptability or versatility
If operation modes are dynamically adjusted based on object characteristics, then the adaptability to different objects is improved, but the control complexity increases
Solution Approach 1:
The control system dynamically adjusts operation modes based on real-time 3D object detection data, transitioning between different control strategies depending on object characteristics such as position, size, and type, making the system adaptable rather than static
4Productivity
If real-time 3D detection and control mode adjustment is implemented, then the productivity is improved through efficient operation, but the use of energy increases due to continuous sensing and processing
Solution Approach 1:
The range finder device continuously detects object positions and the control system continuously adjusts operation modes without interruption, maintaining optimal efficiency throughout the entire operation rather than requiring periodic recalibration or manual intervention
