Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If force sensors are integrated into clamping devices to detect weight changes, then measurement precision of processing unit weight is improved, but device complexity increases
Solution Approach 1:
The force sensor acts as an intermediary element between the processing unit and the clamping device base body. It indirectly measures weight by detecting forces transmitted through the clamping device structure, enabling precise weight measurement without direct contact with the processing unit while maintaining system modularity.
Solution Approach 2:
The patent replaces traditional mechanical weight measurement systems with force sensors that detect forces electrically. This substitution enables more precise and dynamic weight monitoring while reducing mechanical complexity through electronic sensing and control.
2Use of energy by moving object
If drive parameters are continuously adjusted based on real-time weight feedback, then energy efficiency is improved, but control system complexity increases
Solution Approach 1:
The control unit continuously receives weight information from the force sensor and automatically adjusts drive parameters in real-time. This closed-loop feedback system optimizes energy efficiency by adapting motor performance to actual load conditions without requiring complex manual intervention or oversimplified open-loop control.
Solution Approach 2:
The system transitions from static drive parameters to dynamic adjustment based on real-time weight changes. The control unit modifies motor characteristics continuously according to measured forces, enabling adaptive energy optimization while maintaining manageable control complexity through automated algorithms.
