Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If complex measuring structures are used for force measurement, then measurement capability is improved, but device complexity increases and installation space requirements worsen
Solution Approach 1:
The patent replaces complex mechanical measuring structures with a magnetic field-based sensor system. Instead of using strain gauges on calibrated metal components or cable pull potentiometers, the invention employs magnetic field sources and sensors to detect relative movements and calculate forces, thereby eliminating the need for complex mechanical measurement apparatus while maintaining measurement capability.
Solution Approach 2:
The magnetic sensor device serves multiple functions: it detects relative movements between components, measures both static and dynamic loads, and provides data for calculating forces without requiring separate mechanical measurement systems. This multi-functionality reduces overall device complexity while improving measurement precision.
2Measurement precision
If displacement measurement on several axes is implemented, then measurement capability is improved, but installation space requirements worsen
Solution Approach 1:
The patent replaces mechanical multi-axis measurement systems with a magnetic field-based sensor arrangement. By positioning multiple magnetic field sources and sensors in specific spatial configurations, the system achieves multi-axis displacement measurement capability without requiring the extensive mechanical structures and installation space that traditional methods would demand.
3Measurement precision
If acceleration measurement is used for dynamic load detection, then measurement capability is improved, but measurement precision worsens
Solution Approach 1:
The patent replaces acceleration-based measurement with direct magnetic field sensing of relative movements. The magnetic sensors directly detect positional changes between components, and forces are calculated from these position measurements, providing more accurate and reliable dynamic load detection compared to acceleration measurement which suffers from integration errors and noise amplification.
4Device complexity
If immersion anchor principle sensors are used, then device simplicity is improved, but measurement capability for highly dynamic loads worsens
Solution Approach 1:
The patent replaces immersion anchor principle sensors with a magnetic field-based sensor system that has no mechanical contact or anchoring requirements. The magnetic sensors can detect highly dynamic movements without the limitations of mechanical anchoring, achieving both device simplicity and superior measurement capability for highly dynamic loads.
