Dynamic 3D Safety Zone Overlay for Crane Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current safety systems for vehicles equipped with working equipment, such as cranes, face challenges in providing user-friendly and adaptive safety solutions that effectively manage safety zones, particularly in complex environments with obstacles like overhead cables and bridges, while ensuring high safety standards.
Innovation Solution
A safety system comprising a control unit, a remote controller, and a display unit that defines and presents three-dimensional safety spaces to the operator, allowing them to choose and activate specific safety zones by inputting space position parameters and safety state commands, thereby controlling the movement of the working equipment within predefined boundaries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed safety boundaries are defined for crane operation, then safety is improved, but adaptability to different work environments deteriorates
Solution Approach 1:
The safety boundary definition is made dynamic rather than fixed. The system allows operators to define different safety boundaries for different work environments and situations. The control unit can adaptively adjust safety boundaries based on real-time conditions, operator inputs, and environmental factors, resolving the contradiction between maintaining fixed safety standards and adapting to varying work environments.
2Reliability
If complex safety monitoring systems are implemented, then safety is improved, but ease of operation deteriorates
Solution Approach 1:
The system incorporates automatic monitoring and alerting functions that reduce the operator's burden. The control unit automatically tracks the crane's position, monitors safety boundaries, and provides warnings or automatic interventions when safety limits are approached, eliminating the need for constant manual monitoring while maintaining high safety standards.
Solution Approach 2:
The system provides continuous feedback to the operator through the display unit, showing real-time information about safety boundaries, crane position, and potential hazards. This feedback mechanism enables operators to make informed decisions without requiring complex manual monitoring procedures, simplifying operation while maintaining safety.
3Reliability
If real-time safety monitoring is implemented, then safety is improved, but information processing requirements increase
Solution Approach 1:
The safety monitoring system is segmented into distinct functional modules: boundary definition, real-time position tracking, comparison logic, and alert generation. Each module processes specific information independently, reducing the overall information processing load while maintaining comprehensive safety monitoring. The display unit presents information in a segmented, organized manner to avoid overwhelming the operator.
