Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If crane information is displayed using conventional two-dimensional visualization methods, then the system structure remains simple, but the ability to three-dimensionally examine crane information is limited
Solution Approach 1:
The patent transitions from two-dimensional display to three-dimensional visualization by capturing crane images with a camera, detecting the crane's position and posture in 3D space, and overlaying working capacity information that reflects spatial relationships. This dimensionality change enables operators to examine crane information from multiple angles and understand spatial context better.
Solution Approach 2:
The patent introduces a terminal device as an intermediary between the crane and the operator. This device captures images, processes position and posture data, calculates working capacity, and presents integrated 3D visualizations. The intermediary handles the complexity of 3D processing while keeping the operator interface relatively simple.
2Measurement precision
If real-time crane position and posture detection is implemented, then working capacity can be accurately calculated, but the measurement and detection complexity increases
Solution Approach 1:
The crane itself serves as part of the detection system through integrated sensors that automatically capture its own position and posture data. The terminal device then processes this self-provided information along with image data to calculate working capacity, reducing the need for separate complex detection equipment.
Solution Approach 2:
The terminal device performs multiple functions: capturing crane images with the camera, detecting position and posture from image information, calculating working capacity from multiple parameters, and displaying integrated results. This multi-functionality consolidates what would otherwise require separate specialized systems.
3Loss of information
If three-dimensional image information is overlaid on camera images, then crane information becomes more comprehensive, but the information processing complexity increases
Solution Approach 1:
The patent merges multiple information sources - camera images, detected position data, posture information, and calculated working capacity - into a single integrated display. This combination presents comprehensive crane information in one unified view rather than requiring separate displays for each parameter.
Solution Approach 2:
The working capacity information is overlaid in a way that reflects three-dimensional spatial relationships on the two-dimensional display. This dimensional representation allows operators to understand the relationship between crane position, posture, and capacity without requiring complex separate visualizations.
