Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing enzymatic detergents are predominantly liquid, posing stability and spillage risks, and are difficult to incorporate into solid compositions while maintaining efficacy, particularly for cleaning medical and dental instruments and ware.
Innovation Solution
Development of stable solid enzymatic detergent compositions comprising alkali metal carbonate, acid, and surfactant, which form a solidification matrix, allowing enzymes like proteases, amylases, and cellulases to maintain efficacy in solid form, with pH adjustment to near neutral to moderately alkaline ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If enzymes are incorporated into solid detergent compositions, then packaging and safety concerns related to spillage are reduced, but enzyme stability and efficacy are compromised
Solution Approach 1:
The patent changes the physical state parameter of the detergent from liquid to solid form while adjusting pH parameters to near neutral to moderately alkaline ranges (pH 6-11 upon dilution), enabling enzyme incorporation into solid compositions without compromising stability or efficacy. This is achieved through careful selection of alkaline builders and buffering systems that maintain optimal pH for enzyme activity in solid format.
Solution Approach 2:
The patent creates a composite solid detergent composition combining multiple components including enzymes, alkaline builders (carbonates, silicates), surfactants, and buffering agents. This composite structure allows the solid formulation to maintain both structural integrity for spill-free handling and chemical conditions necessary for enzyme activity, resolving the contradiction between solid form stability and enzyme efficacy.
2Volume of stationary object
If enzymes are incorporated into solid detergent compositions, then packaging volume is reduced, but formulation complexity increases
Solution Approach 1:
The patent merges multiple functional components into a single solid detergent composition: enzymes for soil breakdown, alkaline builders for pH maintenance and water softening, surfactants for emulsification, and buffering agents for pH stability. This consolidation achieves space-efficient packaging while managing formulation complexity through synergistic component selection where each ingredient serves multiple functions.
Solution Approach 2:
The solid detergent composition is designed with multi-functional ingredients that perform multiple roles. For example, alkaline builders provide both pH control and water softening, while buffering agents maintain pH stability and enhance enzyme activity. This multi-functionality reduces the number of separate components needed, simplifying the overall formulation despite the solid state requirements.
3Reliability
If liquid enzymatic detergents are used, then enzyme activity is maintained, but stability and spillage risks increase
Solution Approach 1:
The patent transforms the composition from liquid to solid state while adjusting pH parameters to ranges optimal for enzyme stability and activity (pH 6-11 upon dilution). This parameter change enables the formulation to achieve both composition stability for spill-free handling and maintained enzyme activity through careful selection of alkaline builders and buffering systems.
Solution Approach 2:
The solid detergent composition is designed as a stable, shelf-ready product that eliminates the need for complex liquid formulations requiring special containers and spill prevention measures. The solid format provides inherent stability and safety, making the product more reliable for storage and handling while maintaining enzyme efficacy until use.
