Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing testing devices for measuring interfacial shear properties between fibers and media fail to account for anchoring force, anchoring length, and anchoring area, and are not adjustable in height, limiting their adaptability to various testing schemes.
Innovation Solution
A testing device with a main body, mounting piece, and fixing plate, featuring L-shaped plates, a connecting rod, displacement micrometer, guiding rods, and adjustable components, allowing for precise measurement of shear performance and height adjustment, enabling the recording of data affected by anchoring force, length, and area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing testing devices are used to measure shear performance, then basic shear testing can be performed, but the device cannot test the influence of anchoring force, anchoring length and anchoring area on shear performance
Solution Approach 1:
The testing device is divided into multiple functional modules: a loading mechanism for applying anchoring force, a measurement mechanism for recording shear performance data, and an adjustable mounting structure. This segmentation allows independent optimization of each function to achieve comprehensive testing capability while maintaining data accuracy.
Solution Approach 2:
The testing device is designed with universal components that can test multiple parameters including anchoring force, anchoring length, anchoring area, and shear performance. The adjustable mounting structure and multi-functional measurement system enable the same device to accommodate various testing requirements without requiring separate specialized equipment.
2Adaptability or versatility
If existing testing devices are used, then shear performance can be measured, but the device is not adjustable in height to adapt to different testing schemes
Solution Approach 1:
The mounting structure incorporates adjustable height components that allow the testing device to dynamically adapt to different testing schemes. The height adjustment mechanism is designed to be operationally convenient, enabling users to quickly modify the device configuration without complex procedures.
3Loss of information
If existing testing devices are used, then basic testing can be performed, but full data recording throughout the testing process is not achieved
Solution Approach 1:
The testing device incorporates data recording mechanisms that continuously monitor and record testing parameters throughout the process. This feedback system ensures complete data capture without requiring overly complex additional equipment, as the recording function is integrated into the existing testing framework.

AI summary
Disclosed is a testing device for measuring interfacial shear properties between fibers and media, including a main body, which is a rectangular plate-like structure with L-shaped plates provided at the bottom ends of the main body, a connecting rod provided at a top right of the main body, a groove provided at the top of the main body; and four rotating grooves are provided inside the groove. The rotating grooves are cylindrical structures with raised centers at both ends; and a mounting piece is installed above the left end of the main body; a magnet of a displacement micrometer is connected to a tension trolley, a high-definition camera is turned on, weights are added into a loading bucket and the fiber movement is observed until the fiber is pulled out or sliding friction occurs, and then the camera is stopped and accurate data is tested.
