Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate control interfaces are used for scanner controller and robot controller, then independent control of each device is achieved, but operation complexity increases and programming becomes more difficult
Solution Approach 1:
The patent combines the scanner control function and robot control function into a single integrated controller. The controller includes a scanner control unit that generates G-code for the scanner and a robot control unit that executes robot operations, both managed through one unified interface. This eliminates the need for separate control systems while simplifying programming, as operators only need to learn one controller interface instead of multiple separate systems.
2Measurement precision
If G-code programming is required for scanner operation, then precise scanner control is achieved, but operator learning burden increases
Solution Approach 1:
The scanner control unit automatically generates G-code programs based on simple parameter inputs from the operator. Instead of requiring operators to manually write complex G-code, the system provides self-service by automatically creating the necessary control code from basic machining parameters, thereby maintaining precise scanner control while eliminating the need for specialized programming knowledge.
Solution Approach 2:
The scanner control unit acts as an intermediary between the simple parameter input interface and the complex scanner control system. It translates user-friendly parameter inputs into precise G-code commands automatically, serving as a mediator that shields operators from complexity while ensuring accurate scanner operation.
3Ease of operation
If unified controller is used for both scanner and robot, then operation simplicity is improved, but control speed synchronization becomes more challenging
Solution Approach 1:
The controller incorporates feedback mechanisms that monitor the operational state of both the scanner and robot in real-time. Based on this feedback, the control units dynamically adjust their operation speeds and timing to maintain synchronization. This allows the unified controller to coordinate both devices effectively without compromising control precision or speed matching.
