Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS is used to detect the position of a tool, then the system can track tool location, but accuracy decreases due to obstacles and communication carrier failures
Solution Approach 1:
The patent introduces a target object as an intermediary carrier that reflects light from the sensor. Instead of directly detecting the tool via GPS signals that fail under obstacles, the system uses a light-reflecting target object attached to the tool, which can be detected by an optical sensor in the facility, thereby mediating the detection process to overcome obstacle interference
Solution Approach 2:
The patent replaces the GPS electromagnetic signal-based detection system with an optical detection system using a light source and light-receiving sensor. This substitution of detection mechanism avoids reliance on communication carriers that fail under obstacles, improving both accuracy and reliability in obstructed environments
2Productivity
If the tool changes direction freely during operation, then work efficiency improves, but GPS-based detection accuracy decreases
Solution Approach 1:
The patent makes the target object rotatable relative to the tool, allowing it to dynamically adjust its orientation. The target object can rotate to maintain optimal alignment with the optical sensor even when the tool changes direction, ensuring continuous accurate detection while the tool operates freely in various orientations
Solution Approach 2:
The patent employs an asymmetric mounting arrangement where the target object is positioned and oriented specifically to face the sensor's detection direction. This asymmetric configuration ensures that the target object maintains optimal detection alignment regardless of the tool's operational orientation, enabling accurate tracking during free directional changes
3Device complexity
If a fixed target object is used on the tool, then the structure is simple, but detection accuracy decreases when the tool orientation changes
Solution Approach 1:
The patent transforms the fixed target object into a rotatable one, allowing it to dynamically adjust its orientation. This dynamic capability enables the target object to maintain optimal alignment with the sensor during tool orientation changes, significantly improving detection accuracy while adding only minimal rotational mechanism complexity
