Multi-Angle Hose Indicator for Rubber Deterioration Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining the deterioration state of rubber hoses, especially the inner rubber, are challenging due to the difficulty in attaching high-precision temperature sensors and ensuring visibility of indicators regardless of the hose's usage state.
Innovation Solution
A hose with an indicator that uses color components extracted by a deterioration state determination device with a deterioration determination model and color change database to determine the deterioration state, featuring color patterns sensitive to deterioration factors attached to the hose body in a visible manner from multiple directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a temperature sensor is installed in the hose to detect temperature, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces the mechanical temperature sensor system with a chemical indicator system. The indicator uses color-changing materials that respond to temperature changes through chemical reactions, eliminating the need for electronic sensors, wiring, and power sources while providing sufficient measurement precision for deterioration assessment
Solution Approach 2:
The patent employs inexpensive indicator materials that can be easily attached to the hose surface. These indicators are designed as simple, disposable components that provide accurate deterioration information without requiring maintenance, calibration, or complex installation infrastructure
2Illumination intensity
If an indicator is attached to a specific location on the hose, then visibility is improved from that location, but visibility deteriorates when the hose is used in different orientations
Solution Approach 1:
The patent transitions from a single-point indicator location to a distributed pattern of indicators across the hose surface. By placing multiple indicators at different positions and orientations, the system ensures that at least one indicator remains visible regardless of how the hose is routed or positioned in three-dimensional space
Solution Approach 2:
The patent divides the indicator system into multiple separate indicator elements distributed across the hose surface. This segmentation allows different portions of the indicator pattern to be visible from different directions, ensuring continuous monitorability regardless of hose orientation or installation configuration
