Hazardous Flexible Material Disinfection via Compression and Convection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current disinfection methods for hazardous flexible materials, such as ultraviolet radiation, high-pressure steam, and chemical disinfectants, are inefficient, energy-intensive, and unsuitable for on-site rapid treatment, failing to effectively disinfect both surfaces and interiors of materials, and often leave chemical residues, posing risks and inefficiencies in storage and transfer.
Innovation Solution
A fast harmless treatment device that uses mechanical compression and high-temperature convection disinfection within a sealed chamber, employing heating tubes and a blowing device to ensure thorough disinfection of both surfaces and interiors of hazardous flexible materials without chemical reagents, reducing energy consumption and space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ultraviolet radiation is used for disinfection, then surface disinfection is achieved, but interior disinfection is not effective
Solution Approach 1:
The device segments the disinfection process into two distinct phases: first ultraviolet radiation for surface disinfection, then high-temperature heating for interior disinfection. This segmentation allows each method to target specific areas (surface vs. interior) that the other cannot reach effectively.
Solution Approach 2:
The device changes the physical parameters of the disinfection environment by transitioning from ultraviolet radiation (electromagnetic parameter) to high-temperature heating (thermal parameter). This parameter change enables the disinfection mechanism to penetrate from surface to interior, overcoming the limitation of ultraviolet radiation alone.
2Reliability
If high-pressure steam equipment is used, then disinfection is achieved, but energy consumption is high and efficiency is low
Solution Approach 1:
The device uses periodic action by alternating between ultraviolet radiation phase and high-temperature heating phase. This periodic operation allows the system to achieve thorough disinfection through multiple stages rather than requiring continuous high-energy steam input, thereby reducing overall energy consumption while maintaining effectiveness.
3Reliability
If chemical disinfectants are used, then disinfection is achieved, but chemical residues remain affecting subsequent treatment
Solution Approach 1:
The device replaces chemical disinfection mechanisms with physical mechanisms: ultraviolet radiation and high-temperature heating. These physical methods achieve disinfection without introducing chemical substances, thereby eliminating the problem of chemical residues that would interfere with subsequent incineration or reuse processes.
4Volume of moving object
If disposable hazardous flexible materials are compressed, then storage efficiency is improved, but storage risks increase
Solution Approach 1:
The device performs preliminary disinfection action (ultraviolet radiation followed by high-temperature heating) before compression and storage. By eliminating pathogens in advance through the two-stage disinfection process, the materials become safe for compression and storage, removing the harmful factors that would otherwise be present during stored compressed state.
