Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional crane operation methods are used, then the crane can perform basic lifting operations, but the operator cannot verify whether the suspension load can be moved to the desired position, resulting in inefficient work
Solution Approach 1:
The system performs preliminary verification of load movement feasibility by calculating movement determination information (load factor, rated load, performance line) before the operator executes the movement operation. The image creator captures the current position, and the movement determination information calculator computes whether the load can be moved to the target position based on crane performance characteristics, allowing the operator to verify feasibility in advance.
Solution Approach 2:
The patent introduces an intermediary verification system consisting of the image creator, movement determination information calculator, and display device. This intermediary system mediates between the operator's intent and the actual movement execution by providing calculated movement determination information that bridges the gap between desired position and feasible operation.
2Reliability
If the operator manually checks movement feasibility, then some verification can be performed, but it requires additional time and reduces work efficiency
Solution Approach 1:
The patent replaces manual mechanical verification with an automated calculation system. The movement determination information calculator automatically computes the load factor, rated load, and performance line based on input parameters (load weight, boom length, jib angle, etc.), substituting the operator's manual checking process with rapid electronic computation that provides accurate results without time loss.
Solution Approach 2:
The system provides immediate feedback to the operator by displaying movement determination information (load factor, rated load, performance line) on the display device. This feedback mechanism allows the operator to quickly verify whether the load can be moved to the desired position without manual calculation, reducing verification time while maintaining high reliability through automated computation.

AI summary
Provided is a work plan verification device capable of improving work efficiency of movement work of a suspension load. The work plan verification device determines whether an operator indicates a movement position of the suspension load on an image (A) displayed on a monitor (30). When a determination is made that the movement position is indicated, a mark is displayed on the movement position (B). Subsequently, a determination is made that the suspension load is suspended on a boom. When the determination is made that the suspension load is suspended, a load factor (C1) which is moving determination information allowing an operator to determine whether the suspension load can be moved to the movement position (B) is calculated, and the calculated load factor is displayed on the image (A).
