Force-Measuring Device Radial Press Elastic Spreader Segmentation

The device segments the force measurement function into two distinct parts: (1) elastic spreader members that perform the force conversion from radial to axial direction, and (2) a separate measurement system (strain gauges or displacement sensors) that accurately measures the resulting axial displacement or force without being affected by the compliance of the elastic elements. This segmentation allows the elastic elements to fulfill their mechanical function while the measurement system independently captures accurate data.

The patent introduces an intermediary measurement system that mediates between the elastic spreader members and the final measurement output. Instead of measuring the force directly through the compliant elastic elements, the system uses strain gauges or displacement sensors as intermediaries to measure the axial displacement or force generated by the spreader members, thereby isolating the measurement process from the compliance effects.

The device separates the motion function from the force measurement function. The thrust members with chamfers provide the necessary swiveling motion capability, while the spreader members and measurement system independently handle the force measurement. This segmentation allows each component to be optimized for its specific function without compromising overall performance.

Instead of making the force-bearing elements swivel (as in prior art), the patent inverts the approach by making the thrust members swivel through chamfered surfaces while the force measurement is performed on the rigid spreader members. This inversion allows swiveling motion to occur in components not intended for force measurement, preserving the strength and measurement accuracy of the force-bearing elements.

The patent replaces complex mechanical force measurement systems with a simpler mechanical-to-electrical transduction system. Instead of using multiple mechanical sensors to directly measure radial forces, the device uses elastic spreader members to convert radial forces into axial displacement or force, which is then measured by simple strain gauges or displacement sensors. This substitution dramatically simplifies the device while maintaining or improving measurement capability.

The patent changes the measurement parameter from direct radial force measurement to axial displacement or axial force measurement. By converting the measurement parameter to a different direction (axial instead of radial), the device can use simple, inexpensive sensors to measure the converted parameter, avoiding the need for complex radial force sensors.
