Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional teaching methods are used to program robot movements, then the robot can execute specific tasks with high precision, but the time and cost required to change work content increases significantly
Solution Approach 1:
The patent segments the robot control program into a library of reusable movement patterns or macros. Instead of programming each complete task from scratch, the system divides complex movements into standardized components that can be independently defined and reused across different work contents, reducing programming time while maintaining precision.
Solution Approach 2:
The patent implements preliminary action by pre-defining and storing common robot movement patterns in a library before actual task execution. These pre-programmed movement sequences are prepared in advance and can be quickly selected and executed for different tasks, eliminating the need for repetitive detailed programming and reducing the time required to adapt to new work content.
2Adaptability or versatility
If detailed reprogramming is performed for each new task, then the robot can adapt to specific work requirements, but the complexity and cost of operation increases
Solution Approach 1:
The patent creates a universal movement library that can serve multiple different tasks and work contents. The standardized movement patterns are designed to be task-agnostic, allowing the same library to support various operations by simply changing the sequence or parameters of movements selected, thereby enhancing adaptability without increasing programming complexity.
Solution Approach 2:
The patent uses copying by allowing users to replicate and reuse existing movement patterns from the library for different tasks. Instead of creating new programs from scratch, users can copy predefined movement sequences and modify them as needed, significantly reducing the complexity of adapting the robot to new work requirements while maintaining high versatility.
3Reliability
If comprehensive teaching processes are implemented, then the robot can accurately perform routine tasks, but the system becomes less suitable for non-routine or changing tasks
Solution Approach 1:
The patent introduces dynamics by creating a flexible movement library that can be dynamically selected and reconfigured based on task requirements. The system allows users to easily add, remove, or modify movement patterns in the library as needed, enabling the robot to reliably execute both routine tasks using predefined patterns and adapt to non-routine tasks by incorporating new movements, thus balancing reliability with versatility.
