Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If visual judgment by a pruner is used to determine whether tree pruning is necessary, then the judgment can be made without additional equipment, but the accuracy is reduced due to manual errors and personnel costs are incurred
Solution Approach 1:
The patent replaces the manual visual inspection method with an automated optical detection system. The laser communication apparatus detects trees obstructing the optical path by analyzing reflected or scattered laser light, substituting human visual judgment with optical-based automatic detection to eliminate manual errors while maintaining equipment simplicity.
2Extent of automation
If laser light reflection intensity is used to detect trees, then automated detection is achieved, but additional apparatus for receiving reflected light is required
Solution Approach 1:
The patent makes the laser communication apparatus itself perform the dual function of communication and obstacle detection. The existing laser transmitter and receiver components are utilized for both their primary communication function and for detecting trees by analyzing light scattering or reflection, eliminating the need for separate detection apparatus while achieving automation.
Solution Approach 2:
The detection function is merged with the communication function within the same apparatus. The laser communication system's transmitted light serves dual purposes: enabling communication and providing the detection signal for tree detection, combining two functions into one integrated system to avoid additional equipment.
3Loss of time
If manual visual inspection is used to check for tree obstructions, then personnel costs are incurred, but no additional detection equipment is needed
Solution Approach 1:
The laser communication apparatus performs self-diagnosis by automatically detecting obstructions in its own optical path. The system monitors its own communication environment using its transmitted laser light, enabling it to identify tree obstructions without requiring external inspection personnel, thus eliminating personnel costs while reducing inspection time.
