Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote operation is performed using conventional methods, then the operator can control the robot, but the operability is limited by the operator's skill level and input device performance
Solution Approach 1:
The system performs preliminary actions by predicting the operator's intended operations based on current operation history and task information. The prediction unit anticipates future operations before the operator actually inputs them, preparing control commands in advance to improve responsiveness and reduce the burden on the operator's skill level.
Solution Approach 2:
The patent replaces the mechanical dependency on operator skill and input device performance with an intelligent prediction system. The prediction unit uses computational algorithms to substitute for the operator's decision-making process, transforming the control system from a purely manual mechanical operation to an intelligent automated assistance system.
2Productivity
If the operator manually controls each action, then precise control is possible, but the operation efficiency decreases due to skill limitations
Solution Approach 1:
The system provides self-service by automatically generating predicted operation commands based on the current task context and operation history. The prediction unit serves itself by continuously analyzing the situation and generating appropriate control commands without requiring constant manual intervention, thereby improving operation efficiency while maintaining ease of use.
Solution Approach 2:
The system implements feedback by continuously monitoring the operation history and task information to refine its predictions. The prediction unit uses feedback from the current operation state and historical data to improve the accuracy of predicted commands, creating a closed-loop system that enhances both efficiency and operational smoothness.
3Productivity
If complex tasks are performed manually, then flexibility is maintained, but the motion control efficiency decreases
Solution Approach 1:
The patent applies segmentation by dividing complex tasks into discrete operation steps that can be individually predicted and optimized. The prediction unit breaks down complex motion sequences into manageable segments based on task information and operation history, allowing each segment to be controlled more efficiently while maintaining overall task flexibility.
