Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning systems leave unwanted residues on surfaces and pose health and environmental risks due to the use of chemical detergents, and there is a need for improved cleaning methods that reduce detergent usage while maintaining cleaning and disinfecting effectiveness.
Innovation Solution
The use of electrochemically activated (EA) water, produced by a functional generator that separates anolyte and catholyte liquids, which are then used as a cleaning solution without surfactants, enhancing cleaning and sanitizing properties through the introduction of fine gas bubbles via sparging devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional chemical detergents are used for cleaning, then cleaning effectiveness is improved, but unwanted residue is left on surfaces and health/environmental risks increase
Solution Approach 1:
The patent applies parameter changes by transitioning from chemical detergent-based cleaning to electrochemically activated water with controlled pH levels (acidic or alkaline) and oxidation-reduction potential. The cleaning mechanism shifts from chemical surfactants to electrochemical parameters (pH, ORP, dissolved oxygen) that can be adjusted to achieve effective cleaning without harmful residues.
Solution Approach 2:
The patent replaces the chemical cleaning mechanism (surfactants and solvents) with an electrochemical system using electrodes, power supplies, and electrolysis cells to generate active species in situ. This substitution eliminates the need for stored chemical detergents and their associated harmful residues while maintaining cleaning effectiveness through electrochemically generated reactive oxygen species and pH control.
2Object-generated harmful factors
If electrochemically activated water is used without surfactants, then residue and environmental impact are reduced, but cleaning efficiency may be compromised
Solution Approach 1:
The patent compensates for the lack of surfactants by precisely controlling electrochemical parameters: pH levels (adjusted to acidic or alkaline ranges), oxidation-reduction potential (ORP), and dissolved oxygen concentration. These parameter adjustments create optimal conditions for cleaning without requiring traditional surfactants, thereby maintaining efficiency while reducing harmful residues.
Solution Approach 2:
The patent introduces fine gas bubbles (oxygen, air, or other gases) as intermediaries to enhance the cleaning action of electrochemically activated water. The bubbles increase surface area contact, improve wetting properties, and provide mechanical agitation that compensates for the absence of surfactants, thereby maintaining cleaning efficiency without adding harmful chemical residues.
3Reliability
If a membrane separates anode and cathode for one-way ion transport, then anolyte and catholyte properties are optimized, but device complexity increases
Solution Approach 1:
The patent uses ion-exchange membranes as intermediaries to selectively separate anolyte and catholyte while allowing controlled ion transport. The membranes enable one-way transport of specific ions (cations or anions) to maintain optimal pH and composition in each compartment without requiring complex mechanical separation systems, thus balancing device complexity with optimized electrolyte properties.

AI summary
A method and an apparatus of manufacturing airtight safety garments via ultrasonic welding, and more particularly, to a method and an apparatus of manufacturing safety garments by heating and melting synthetic fiber sheets at a melting point or higher via ultrasonic welding and then pressing the fiber sheets against each other to bond them together. The method includes: (a) feeding two fiber sheets; (b) automatically aligning edges of the fiber sheets so that the fiber sheets overlap partially with each other; (c) adjusting a height of a pattern roller according to a thickness of overlaps of the fiber sheets; and (d) transmitting energy to the pattern roller, by an ultrasonic generator, to weld and bond the overlaps of the fiber sheets.
