Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional detergent products containing soft beads made of polyethylene, polypropylene, or nylon can flow through sewers and into oceans, causing environmental harm due to their plastic composition.
Innovation Solution
A detergent composition and manufacturing method utilizing an aqueous phase with liquid water, an oil phase containing coffee grounds dispersed in oil droplets, and an emulsifying agent to form an oil-in-water emulsion, which isolates coffee grounds from water, preventing water absorption and precipitation issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If soft beads made of polyethylene, polypropylene, or nylon are added to detergent composition, then skin exfoliation capability is improved, but environmental harm increases due to plastic particles flowing into oceans
Solution Approach 1:
The patent replaces harmful plastic soft beads with coffee grounds, which are biodegradable and environmentally friendly. The coffee grounds provide the same exfoliation function while eliminating the environmental harm caused by plastic particles flowing into oceans and waterways.
Solution Approach 2:
The patent changes the material composition parameter from synthetic plastics (polyethylene, polypropylene, nylon) to natural organic material (coffee grounds). This parameter change maintains the exfoliation function while resolving the environmental harm issue.
2Reliability
If coffee grounds are directly mixed with aqueous phase, then exfoliation function is provided, but coffee grounds absorb water causing precipitation and storage problems
Solution Approach 1:
The patent introduces an oil phase as an intermediary substance between the coffee grounds and aqueous phase. The coffee grounds are dispersed in the oil phase first, which prevents them from directly contacting and absorbing water. This intermediary layer maintains uniform dispersion and prevents precipitation during storage.
Solution Approach 2:
The patent creates a nested structure where coffee grounds are embedded within oil droplets, which are then dispersed in the aqueous phase. This nested arrangement (coffee grounds inside oil droplets inside aqueous phase) prevents water absorption by coffee grounds while maintaining stable suspension.
3Stability of the object's composition
If oil phase containing coffee grounds is dispersed in aqueous phase, then uniform suspension is achieved, but emulsifying agent is required to maintain stability
Solution Approach 1:
The patent utilizes the natural surface-active properties of coffee grounds themselves to provide emulsification. The coffee grounds act as their own emulsifying agent, reducing the need for additional chemical emulsifiers and simplifying the overall composition while maintaining stable oil-in-water emulsion.
