Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operator manually switches between detection ranges, then the operator can control detection coverage, but the system complexity increases and operator workload increases
Solution Approach 1:
The obstacle detection system automatically adjusts the detection range based on the vehicle's work state (stationary vs. moving) without requiring manual operator input. The system serves itself by monitoring its own operational parameters and making appropriate adjustments to the detection range, thereby reducing operator workload while maintaining simple control architecture
Solution Approach 2:
The detection range is made dynamic and automatically adapts to different work states. When the vehicle is moving, the system expands the detection range to provide maximum coverage; when stationary, it reduces the range to focus on immediate surroundings. This dynamic adjustment eliminates the need for manual switching while optimizing detection coverage for each operational mode
2Reliability
If the detection range is set to long range during stationary operation, then maximum detection coverage is achieved, but unnecessary energy is consumed and operator attention is required
Solution Approach 1:
The system dynamically adjusts the detection range based on the vehicle's operational state. During stationary operation, the detection range is automatically reduced to a shorter range, conserving energy while maintaining adequate detection coverage for the immediate work area. When the vehicle begins moving, the range automatically expands to long range to ensure maximum detection coverage, eliminating the need for continuous operator monitoring
Solution Approach 2:
The system changes the detection range parameter automatically based on work state transitions. By monitoring vehicle motion parameters, the system adjusts the detection range from short to long and vice versa, optimizing energy consumption while maintaining reliable detection coverage appropriate for each operational mode
3Use of energy by moving object
If the detection range is set to short range during movement, then energy is conserved, but detection coverage is insufficient for safety
Solution Approach 1:
The detection range is dynamically expanded to long range when the vehicle is in motion, ensuring maximum detection coverage for safety while conserving energy during stationary periods. The system automatically transitions between range modes based on detected vehicle movement, providing appropriate coverage without continuous operator intervention
Solution Approach 2:
The system uses feedback from vehicle motion sensors to automatically adjust the detection range. When movement is detected, the system responds by expanding the detection range to ensure adequate coverage; when movement stops, it reduces the range to conserve energy. This closed-loop feedback mechanism ensures safety during movement while optimizing energy consumption

AI summary
Methods and apparatus are provided for automatically changing an obstacle detection range setting of an obstacle detection system based at least in part on a determination of a change in work state of a self-propelled vehicle. The change in work state may be a change from a transport state in which the vehicle is moving across a ground surface, to a stationary operating state. Upon detecting a change to a stationary operating state the obstacle detection range may be automatically changed to a shorter range. Upon detecting a change to a transport state the obstacle detection range may be automatically changed to a longer range.
