Solution Overview
Problem
Current methods for testing hose kink resistance fail to provide a comprehensive and objective means to quantify and visually compare the performance of hoses under simulated usage conditions, particularly in terms of fluid flow rate, backpressure, torque, and twist resistance.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If hoses are tested under simulated usage conditions with fluid circulation and twisting, then the accuracy and comprehensiveness of kink resistance measurement is improved, but the complexity of the testing device increases
Solution Approach 1:
The testing device is divided into separate functional modules: a fixture for securing the hose, a pressure source for fluid circulation, a twist-inducing mechanism for applying rotational force, and measurement systems for monitoring flow rate, backpressure, and torque. This segmentation allows each component to be optimized independently while maintaining overall system functionality for comprehensive kink resistance testing
Solution Approach 2:
The testing device integrates multiple testing functions into a single system that can simultaneously measure flow rate, backpressure, and torque while circulating fluid through the hose. The fixture and twist-inducing mechanism work together to provide both mechanical constraint and controlled deformation, enabling comprehensive evaluation of hose performance under simulated usage conditions without requiring multiple separate testing apparatus
2Productivity
If multiple hoses are tested simultaneously with equal flow rates, then the productivity and efficiency of testing is improved, but the complexity of flow rate control increases
Solution Approach 1:
Multiple hoses are connected to a common fluid circulation system where a single pressure source supplies fluid to all hoses simultaneously. Flow rate control mechanisms are integrated into the fixture assembly, allowing equal or controlled differential flow rates to be maintained across multiple hoses without requiring separate pumping systems for each hose, thereby improving testing efficiency while managing system complexity
