Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing metal salts used for binding pollutants and odor-forming substances are typically water-insoluble and lack surface-active properties, limiting their effectiveness in chemical binding and adsorption applications.
Innovation Solution
Complexed metal salts are formed by combining water-soluble ligands with bifunctional or polyfunctional complexing agents, creating water-soluble and surface-active compounds that can be deposited on carrier materials for enhanced pollutant and odor binding capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If water-insoluble metal salts are used for binding pollutants, then they can provide deodorizing effect and chemical binding capability, but they lack water solubility and surface-active properties which limits their effectiveness
Solution Approach 1:
The patent creates composite structures by combining water-insoluble metal salts with water-soluble surfactants to form complexed metal salts. This composite approach allows the material to simultaneously possess the deodorizing capability of the metal salt and the water solubility/surface activity of the surfactant, resolving the contradiction between reliability and ease of operation.
Solution Approach 2:
The patent changes the chemical parameters of the metal salt by forming complexes with ligands and complexing agents. This transformation modifies the solubility and surface activity parameters while preserving the core deodorizing function, allowing the material to meet both requirements of effectiveness and ease of use.
2Ease of operation
If complexed metal salts are formed with water-soluble ligands and complexing agents, then water solubility and surface activity are improved, but the complexity of the chemical composition increases
Solution Approach 1:
The patent segments the complexed metal salt into distinct functional components: the metal salt core providing deodorizing activity, ligands providing structural framework, and complexing agents providing water solubility. This segmentation allows each component to be optimized independently while maintaining overall functionality, managing composition complexity effectively.
3Reliability
If metal salts are deposited on carrier materials, then adsorption capability for pollutants is enhanced, but the manufacturing process becomes more complex
Solution Approach 1:
The patent applies complexed metal salts to carrier materials through straightforward deposition processes. The complexed metal salt is prepared in advance with all necessary solubility and activity properties, allowing simple subsequent application to the carrier without requiring complex in-situ formation processes, thus enhancing adsorption capability while maintaining manufacturing simplicity.
