Crane Hook Destination Reading for Guided Load Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing crane systems require manual acquisition of load target arrangement information from IC tags, which is cumbersome and decreases work efficiency.
Innovation Solution
A crane equipped with an information-reading unit on the hook to acquire transportation destination information from an information storage unit on the load, a control unit to calculate the necessary crane operations, and a display unit to present this information to the operator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual acquisition of target arrangement information from IC tag is used, then the crane system structure remains simple, but the work efficiency deteriorates
Solution Approach 1:
The crane system automatically acquires target arrangement information through the information reading unit without requiring manual intervention. The system serves itself by autonomously reading data from the IC tag attached to the load, eliminating the need for operators to manually record or input transportation destination information, thereby improving work efficiency while maintaining relatively simple system structure
Solution Approach 2:
The patent replaces manual mechanical information acquisition methods with an automated information reading unit that uses electromagnetic fields to read data from IC tags. This substitution of manual operations with automated electronic reading systems improves productivity while adding only minimal system complexity through the integration of the reading unit and control unit
2Extent of automation
If information reading unit is added to the hook, then the automation level improves, but the device complexity increases
Solution Approach 1:
The hook is designed with multi-functionality by integrating the information reading unit directly onto it. The hook not only performs its traditional function of suspending and transporting loads but also serves as a platform for automated information acquisition. This universal design approach increases automation level while minimizing additional structural complexity by combining multiple functions into a single integrated component
Solution Approach 2:
The information reading unit is integrated within or onto the hook structure, creating a nested configuration where the reading unit is contained within or attached to the existing hook assembly. This nesting approach allows the automation function to be added without significantly increasing overall device complexity, as the reading unit leverages the existing hook structure rather than requiring a completely separate system
3Ease of operation
If automatic information acquisition is implemented, then the manual effort is reduced, but the information processing complexity increases
Solution Approach 1:
The control unit automatically processes the information acquired by the reading unit and generates appropriate control signals for the crane operations. This feedback mechanism ensures that the transportation destination information and operation information are seamlessly integrated into the crane's control system, reducing manual effort while managing information processing complexity through automated feedback loops rather than complex manual procedures
