Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single laser emitter is used to measure positions, then the device structure is simple, but the measurement precision and versatility are insufficient
Solution Approach 1:
The laser emitting device is divided into multiple independent laser emitters (first laser emitter and second laser emitter) that can be controlled separately. Each emitter can be positioned and oriented independently to measure different coordinates, thereby improving measurement precision without requiring a single complex positioning system.
Solution Approach 2:
The patent introduces a third dimension by enabling the laser emitters to be oriented in different directions (first direction and second direction perpendicular to each other). This allows the system to measure positions in multiple spatial dimensions simultaneously, enhancing measurement capability while maintaining relatively simple emitter structures.
2Adaptability or versatility
If the laser emitting device is fixed in one orientation, then the device structure is simple, but the adaptability to measure different planes is limited
Solution Approach 1:
The laser emitting device is mounted on a carrier that enables dynamic repositioning and reorientation. The carrier allows the laser emitters to be moved between different positions and oriented in different directions (first and second directions), providing adaptability to measure various virtual planes while using a relatively simple mechanical linkage mechanism.
3Measurement precision
If coordinates are not resettable, then the device operation is simple, but the measurement accuracy for different positions is compromised
Solution Approach 1:
The detecting device automatically detects and records the coordinates of the laser emitting device at different positions. The system self-adjusts by comparing current coordinates with stored initial coordinates, eliminating the need for manual coordinate entry or complex reset procedures. This maintains high measurement accuracy while simplifying operation through automatic coordinate management.
