Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the autonomous movement device moves at a constant high speed, then productivity is improved, but reliability deteriorates because the device cannot adapt to different control states
Solution Approach 1:
The autonomous movement device dynamically adjusts its movement speed based on the current control state (cooperation mode, connection mode, or caution mode). The control unit changes the movement speed from a first speed in cooperation mode to a second speed in connection mode, and to a third speed in caution mode, making the system adaptive rather than static.
Solution Approach 2:
The invention changes the movement speed parameter according to different control states. By defining multiple speed levels (first speed, second speed, third speed) corresponding to different operational modes, the system optimizes productivity while maintaining reliability through parameter adaptation.
2Reliability
If the autonomous movement device uses multiple control modes with different speeds, then reliability is improved through better control state management, but device complexity increases
Solution Approach 1:
The control unit continuously monitors the control state (determining whether the device is in cooperation mode, connection mode, or caution mode) and provides feedback to adjust the movement speed accordingly. This closed-loop control improves reliability by ensuring the device responds appropriately to changing conditions.
Solution Approach 2:
The control space is segmented into three distinct modes (cooperation mode, connection mode, caution mode), each with its own speed parameter. This segmentation allows the system to manage complexity by dividing the control problem into discrete, manageable states rather than handling continuous variation.
3Productivity
If the autonomous movement device prioritizes fast movement, then productivity is improved, but position accuracy deteriorates due to reduced control precision at higher speeds
Solution Approach 1:
The movement speed is dynamically adjusted based on the control state and position accuracy requirements. In caution mode where position accuracy is critical, the device moves at a reduced third speed. In cooperation mode where efficiency is prioritized, the device moves at a higher first speed, achieving a dynamic balance between productivity and precision.
