Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional manual methods are used to set end effector postures, then the setup process is simple, but the positioning accuracy and operational precision are insufficient
Solution Approach 1:
The patent introduces line lasers as an intermediary tool between the operator and the end effector positioning process. The lasers provide visual reference lines that mediate the alignment process, enabling precise positioning without requiring complex mechanical positioning mechanisms. The line lasers serve as a mediating reference system that simplifies the complex task of accurate end effector positioning.
Solution Approach 2:
The patent replaces traditional mechanical positioning mechanisms with an optical-based laser alignment system. Instead of using complex mechanical adjustment devices, motors, or sensors to achieve precise positioning, the system uses line lasers to provide visual guidance for manual alignment, substituting mechanical complexity with optical simplicity while maintaining high positioning accuracy.
2Manufacturing precision
If complex positioning mechanisms are used to achieve accurate end effector postures, then the positioning accuracy improves, but the device complexity and ease of operation deteriorate
Solution Approach 1:
The line lasers act as an intermediary reference system that simplifies the operation of positioning the end effector. Operators can visually align the end effector with the laser lines, making the complex task of achieving precise posture simple and intuitive. The lasers mediate between the operator's intent and the precise positioning requirement.
Solution Approach 2:
The patent utilizes the visual property of light emission from the line lasers to create high-contrast reference lines that are easily visible against the background. This visual contrast enables operators to quickly and easily identify alignment positions, making the posture setting process simple and efficient without requiring complex mechanical aids.
3Measurement precision
If multiple light-emitting parts are added to the distal part, then the alignment capability is improved, but the device weight and volume increase
Solution Approach 1:
The patent uses two line lasers (first and second light-emitting parts) which provides more than the minimum single laser reference, creating a two-dimensional alignment reference system. This partial redundancy of lighting components enhances alignment precision in multiple directions without requiring excessive additional weight, as only two compact laser modules are added rather than a full mechanical positioning system.

AI summary
According to one embodiment, a robot includes a manipulator, a first end effector and first and second light-emitting parts. The first end effector is mounted to a distal part of the manipulator. The first light-emitting part is mounted to the distal part, the first light-emitting part irradiating a first line laser in a first direction. The second light-emitting part is mounted to the distal part, the second light-emitting part irradiating a second line laser in a second direction. The first direction is tilted with respect to an orientation of the first end effector in a first plane, the first plane being parallel to a direction from the distal part toward the first end effector. The second direction is tilted with respect to the orientation of the first end effector in a second plane, the second plane being parallel to the first direction and crossing the first plane.
