Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for identifying and removing contaminants from textiles, such as clothing and bedding, are unreliable and often require manual inspection, making it difficult to determine the composition and origin of contaminants, which can lead to ineffective cleaning processes.
Innovation Solution
A biosensor-based system that uses biologically active immobilized systems, such as antibodies, enzymes, or microorganisms, to measure physicochemical changes caused by contaminants, providing reliable information on their composition and recommending optimal cleaning strategies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional sensors (pH, conductivity, turbidity) are used to detect contamination, then the device complexity is low, but the measurement precision and reliability of contaminant composition identification are insufficient
Solution Approach 1:
The patent changes the detection parameter from general physical properties (turbidity, conductivity) to specific biochemical parameters (enzyme activity, antigen-antibody binding) that directly indicate contaminant composition. This allows precise identification of contaminant type while using targeted biosensors rather than complex multi-parameter systems.
Solution Approach 2:
The patent introduces biosensors as intermediary elements that specifically interact with contaminants through biochemical mechanisms (enzyme-substrate binding, antigen-antibody recognition). These biosensors act as mediators that convert complex contaminant composition information into measurable signals, achieving high precision without requiring direct complex analysis of all contaminant properties.
2Productivity
If manual inspection is used to identify contaminants, then the device complexity is low, but the productivity and reliability of contaminant detection are reduced
Solution Approach 1:
The patent replaces manual visual inspection (mechanical/human system) with automated biosensor-based detection. The biosensors automatically interact with contaminants and generate measurable signals, eliminating the need for manual inspection while providing faster, more reliable results. This substitution introduces controlled complexity in exchange for significant gains in productivity and reliability.
3Reliability
If general cleaning programs are used without contaminant identification, then the ease of operation is high, but the cleaning effectiveness is reduced
Solution Approach 1:
The patent implements feedback by using biosensor measurement results to determine appropriate cleaning parameters. The system automatically adjusts cleaning program selection and parameters based on identified contaminant composition, ensuring effective cleaning without requiring user expertise. This feedback loop maintains ease of operation while significantly improving cleaning reliability.
