Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If force detection modules are added to the tool holder, then measurement precision of force variations is improved, but device complexity increases
Solution Approach 1:
The force detection device is divided into two separate force detection modules, each with multiple strain detection components arranged in specific patterns. This segmentation allows independent detection of forces at different locations and directions, improving measurement precision while keeping each module's complexity manageable through modular design.
Solution Approach 2:
The strain detection components are arranged in multi-dimensional configurations including radial directions and axial positions. By detecting forces from multiple spatial dimensions simultaneously, the system achieves comprehensive force measurement precision without requiring a single overly complex detection mechanism.
2Measurement precision
If multiple strain detection components are installed to detect forces in different directions, then measurement precision is improved, but manufacturing complexity increases
Solution Approach 1:
The detection system is segmented into two independent modules, each containing strain detection components for specific measurement tasks. This modular segmentation simplifies the manufacturing and assembly process compared to integrating all detection functions into a single complex unit, while still achieving multi-axis force detection precision.
Solution Approach 2:
Each force detection module is designed with multiple strain detection components that can detect forces in multiple directions (radial and axial). This multi-functionality reduces the need for separate dedicated sensors for each axis, simplifying the overall manufacturing process while maintaining comprehensive measurement capabilities.
3Reliability
If force detection modules are added to monitor operational conditions, then reliability is improved, but device complexity increases
Solution Approach 1:
The force detection modules are pre-installed in the tool holder structure during manufacturing, with strain detection components positioned at optimal locations before the tool holder is put into service. This preliminary action ensures immediate operational monitoring capability, improving reliability from the start without requiring complex post-installation configurations.
Solution Approach 2:
The strain detection components continuously monitor force variations and provide real-time feedback on operational conditions. This feedback mechanism improves reliability by enabling immediate detection of abnormal forces, vibrations, or tilting, allowing for timely intervention while maintaining a relatively simple detection system architecture.
