Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining the deterioration state of hoses, such as those described in Patent Document 1, require the installation of high-precision temperature sensors, which are costly and difficult to attach, especially for outdoor use.
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, where a first indicator is attached to the external surface of the hose body and a second indicator is attached to the fitting, and the color components are compared to determine the deterioration state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a temperature sensor is installed in the hose to detect temperature, then the deterioration state can be determined with high accuracy, but the cost increases and the device becomes difficult to attach
Solution Approach 1:
The patent uses color indicators as visual copies or proxies for temperature data instead of installing physical temperature sensors. The indicators change color based on temperature exposure, allowing deterioration assessment through color comparison rather than direct electronic measurement, thereby eliminating sensor installation complexity while maintaining determination accuracy
Solution Approach 2:
The patent replaces the mechanical/electronic temperature sensor system with a chemical/color-based indicator system. Instead of using electronic sensors to measure temperature, the invention uses color-changing materials that respond to temperature and other deterioration factors, substituting a complex electronic measurement system with a simple visual indication system
2Measurement precision
If a high-precision temperature sensor is used for outdoor hose monitoring, then measurement accuracy is improved, but the cost becomes prohibitively high
Solution Approach 1:
The patent employs inexpensive color indicators that can be easily manufactured and attached to hoses instead of costly high-precision temperature sensors. These indicators are simple color-changing materials that provide sufficient information for deterioration assessment at a fraction of the cost of electronic sensor systems
Solution Approach 2:
The invention uses color indicators as low-cost visual proxies for temperature monitoring. Rather than investing in expensive electronic sensors, the system captures temperature and deterioration information through color changes that can be read by standard imaging devices, dramatically reducing manufacturing costs while maintaining adequate measurement precision
3Reliability
If multiple indicators are attached to different positions, then comprehensive deterioration monitoring is achieved, but the device complexity increases
Solution Approach 1:
The patent divides the monitoring function into multiple color indicators placed at different positions on the hose (such as near the fitting and at intermediate points). Each indicator independently monitors local conditions, and by comparing their color states, the system comprehensively assesses overall hose deterioration without requiring a single complex sensor system
Solution Approach 2:
The patent combines multiple color indicators into a unified visual monitoring system. By capturing images of all indicators and comparing their color components, the system integrates information from multiple locations into a single deterioration assessment, achieving comprehensive monitoring while keeping the overall system simple through unified image processing
