Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a non-rotary (fixing) type torque sensor is used, then the configuration is simple and manufacturing cost is low, but it cannot be applied to high-speed rotating machines requiring rotary movement in both shafts
Solution Approach 1:
The patent merges the torque measurement function with the power transmission function by integrating the load cell directly into the power transmission apparatus structure. The load cell is formed between the outer body and inner body that are already present for power transmission, eliminating the need for separate torque measurement devices and allowing simultaneous rotary movement while measuring torque.
Solution Approach 2:
The power transmission apparatus is designed to serve dual purposes: transmitting power through the outer and inner bodies while simultaneously measuring torque through the integrated load cell. This multi-functional design allows the same structure to handle both power transmission and torque measurement in rotating machines.
2Adaptability or versatility
If a rotary torque sensor (contact or non-contact type) is used, then it can be freely used in various high-speed rotating machines, but the configuration becomes complicated and manufacturing cost increases
Solution Approach 1:
The patent combines the torque measurement function with the existing power transmission structure by integrating the load cell between the outer body and inner body. This eliminates the need for separate contact or non-contact signal transmission means, simplifying the configuration while maintaining applicability to high-speed rotating machines.
Solution Approach 2:
The load cell is positioned to directly measure torque through the power transmission components themselves (outer body and inner body), allowing the system to measure torque through its own operational components without requiring additional dedicated measurement infrastructure.
3Adaptability or versatility
If a rotary torque sensor (non-contact type) is used, then rotational motion is possible on both shafts and torque can be measured at a fixed position, but it is expensive due to magnetic field change or optical displacement detection
Solution Approach 1:
The patent replaces expensive magnetic field or optical detection systems with a mechanical load cell that directly measures torque through physical compression or tension. This mechanical approach achieves the same rotational measurement capability at a lower manufacturing cost.
Solution Approach 2:
The load cell provides a cost-effective alternative to expensive magnetic or optical sensors, using a simpler mechanical component that achieves torque measurement without the high manufacturing costs associated with magnetic field change or optical displacement detection systems.
4Measurement precision
If a separate torque sensor is added to measure shaft strain, then torque measurement is achieved, but additional space is required causing the shaft to be elongated
Solution Approach 1:
The patent merges the torque measurement function into the existing power transmission structure by positioning the load cell between the outer body and inner body. This integration eliminates the need for additional separate torque sensors and avoids elongating the shaft, as the measurement function is incorporated into the existing compact structure.
Solution Approach 2:
The load cell is nested within the existing power transmission apparatus structure, utilizing the space between the outer body and inner body. This nesting approach allows torque measurement without requiring additional external space that would elongate the shaft.
