Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing test devices for high-pressure water tightness of profiled components can only test either water tightness or mechanical performances, requiring multiple stages and increasing test time and component damage due to repeated loading.
Innovation Solution
A test device with a toggle mechanism that includes a drive assembly and toggle levers, allowing simultaneous testing of electrical and mechanical performances under high-pressure water conditions, using a carrier stage with a receiving groove and sealing assembly to facilitate both types of tests without damaging the components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing test devices test only one performance at a time, then testing accuracy is maintained, but test time increases and component damage occurs due to repeated loading
Solution Approach 1:
The patent combines water tightness testing and mechanical performance testing into a single integrated test device. The testing platform simultaneously performs both types of tests on profiled components, eliminating the need for sequential testing and reducing test time while maintaining accuracy through dedicated sensing systems for each test type
Solution Approach 2:
The test device is designed with multi-functional capabilities to perform both water tightness testing and mechanical performance testing on the same component within a single test cycle. The system includes multiple carrier stages and toggle mechanisms that enable diverse testing functions without requiring component transfer between different test equipment
2Adaptability or versatility
If components are transferred between carrier stages for different tests, then testing completeness is achieved, but component damage increases due to repeated loading
Solution Approach 1:
The patent integrates multiple testing functions into a single stationary test platform where components remain on one carrier stage throughout the testing process. The toggle mechanism enables both water tightness and mechanical tests to be performed on the same component without transfer, reducing handling and repeated loading that could damage the component
Solution Approach 2:
The test device employs a toggle mechanism that can dynamically adjust between different testing modes. The mechanism allows the system to switch between water tightness testing configuration and mechanical performance testing configuration without moving the component between carrier stages, thereby maintaining component integrity while achieving comprehensive testing
3Ease of manufacture
If test devices have simple structure, then manufacturing cost is reduced, but testing capability is limited for complex profiled components
Solution Approach 1:
The test device is designed with modular segmented structures including multiple independent carrier stages, separate toggle mechanisms for different test types, and distinct sensing systems. This segmentation allows the complex testing capabilities to be achieved through combinations of standardized modules, balancing manufacturing cost with enhanced testing capability for complex profiled components
