Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the detection range is set to cover the entire circumference of the work machine, then the obstacle detection coverage is improved, but unnecessary obstacle notifications occur in directions where obstacles are not relevant to the current work operation
Solution Approach 1:
The detection range is made dynamically adjustable based on the current work operation. The system allows the operator to change the detection range according to the specific work content, making the monitoring area flexible rather than fixed. This resolves the contradiction by enabling the system to adapt the detection coverage to match the actual operational needs, reducing unnecessary notifications while maintaining reliable detection where needed.
Solution Approach 2:
The system changes the parameter of detection range size based on the work operation type. By allowing the operator to adjust the detection range parameter, the system can optimize between comprehensive coverage and reduced false notifications depending on the specific work context, thereby resolving the technical contradiction.
2Object-generated harmful factors
If the detection range is reduced to match specific work operations, then unnecessary obstacle notifications are reduced, but the obstacle detection coverage in other directions is insufficient
Solution Approach 1:
The system provides dynamic adjustability of the detection range, allowing the operator to expand or contract the monitoring area based on the current work operation. This ensures that the detection coverage is sufficient for the specific task while avoiding unnecessary notifications, resolving the contradiction between reduced notifications and maintained detection reliability.
Solution Approach 2:
The detection range parameter is made changeable according to work operation requirements. The operator can adjust the parameter to achieve the optimal balance between reducing false notifications and maintaining adequate detection coverage for the current operational context.
3Device complexity
If the detection range is fixed, then the system complexity is reduced, but the system cannot adapt to different work operations
Solution Approach 1:
The system incorporates dynamic adjustability of the detection range without significantly increasing overall system complexity. By providing a simple mechanism for the operator to change the detection range based on work operation type, the system achieves high adaptability while maintaining relatively simple configuration.
Solution Approach 2:
The obstacle notification system is designed to perform multiple functions by allowing the detection range to be adjusted for different work operations. This universal design enables the same system to adapt to various operational contexts, resolving the contradiction between simplicity and adaptability.

AI summary
An obstacle determination unit determines whether or not an obstacle is within a detection range being a detection target of the obstacle. A notification unit gives notification indicating the obstacle when determined as the obstacle being present. An operation input unit receives an operation to the display unit for changing the detection range. A change unit changes the size of the detection range based on the operation.
