Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If benefit agents are used at high levels in consumer products, then the effectiveness of benefit agents is improved, but the cost of the product increases and delivery efficiency remains poor
Solution Approach 1:
The benefit agent is segmented into individual delivery particles, each containing a core material surrounded by a wall material. This segmentation allows the benefit agent to be delivered in controlled, discrete units, improving delivery efficiency and reducing the total quantity needed while maintaining effectiveness.
Solution Approach 2:
The patent applies parameter changes by controlling the physical and chemical characteristics of the delivery particles, including fracture strength (0.1-10 MPa), particle size (1-100 micrometers), and wall thickness (1-10 micrometers). These parameter optimizations enable efficient benefit agent delivery at lower concentrations, reducing cost while maintaining effectiveness.
2Reliability
If benefit agents are used at high levels in consumer products, then the effectiveness of benefit agents is improved, but the delivery efficiency remains poor due to physical or chemical characteristics
Solution Approach 1:
The patent optimizes delivery efficiency by controlling critical parameters of the delivery particles: fracture strength (0.1-10 MPa) for controlled release, particle size (1-100 micrometers) for distribution and penetration, and wall thickness (1-10 micrometers) for stability and release rate. These parameter changes enable efficient benefit agent delivery without requiring high concentrations.
Solution Approach 2:
The delivery particle is constructed as a composite material with a core material containing the benefit agent and a surrounding wall material with specific mechanical and chemical properties. This composite structure enables controlled release and improved delivery efficiency by protecting the benefit agent until the appropriate release conditions are met.
3Reliability
If benefit agents are used at high levels in consumer products, then the effectiveness of benefit agents is improved, but compatibility with other compositional components deteriorates
Solution Approach 1:
By segmenting the benefit agent into individual delivery particles with protective wall materials, the patent isolates the benefit agent from incompatible components in the consumer product formulation. This segmentation maintains compatibility with other ingredients while preserving the effectiveness of the benefit agent through controlled release mechanisms.
4Productivity
If delivery efficiency of benefit agents is improved, then the effectiveness of benefit agents is maximized, but the complexity of particle structure and manufacturing increases
Solution Approach 1:
The patent employs a composite particle structure with a core material and wall material that has specific, optimized properties (fracture strength 0.1-10 MPa, particle size 1-100 micrometers, wall thickness 1-10 micrometers). While this composite structure improves delivery efficiency, the patent balances complexity by defining specific parameter ranges that can be manufactured using established processes, avoiding excessive structural complexity.
