Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Benefit agents in consumer products, such as perfumes and silicones, are often expensive and less effective due to difficulties in improving their delivery efficiencies, which can be attributed to their physical or chemical characteristics and incompatibility with other components or the treated site.
Innovation Solution

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 the agents are still less effective due to delivery efficiency issues
Solution Approach 1:
The benefit agent is segmented into individual delivery particles, each containing a core material and wall material structure. This segmentation allows for controlled release and improved delivery efficiency, enabling lower overall quantities of benefit agent to be used while maintaining or enhancing effectiveness.
Solution Approach 2:
The invention changes the physical and chemical parameters of the benefit agent by encapsulating it within delivery particles with specific fracture strength, particle size, and wall thickness characteristics. This parameter transformation improves delivery efficiency and allows the benefit agent to be more effective at lower concentrations.
2Reliability
If benefit agents are used at high levels to compensate for delivery inefficiency, then the effectiveness is improved, but the manufacturing cost increases due to the expensive nature of benefit agents
Solution Approach 1:
By segmenting the benefit agent into delivery particles, the invention enables more efficient utilization of the expensive benefit agent material. Less benefit agent is required to achieve the same or better effect, directly reducing manufacturing costs.
Solution Approach 2:
The delivery particle is a composite material structure combining core material (benefit agent) and wall material. This composite structure protects and delivers the expensive benefit agent more efficiently, reducing the total quantity needed and thereby lowering manufacturing costs.
3Reliability
If benefit agents are used in consumer products, then the desired benefit is achieved, but the agents are lost due to their physical or chemical characteristics and incompatibility with other components
Solution Approach 1:
The wall material acts as an intermediary between the benefit agent core and the external environment (other product components). This intermediary layer protects the benefit agent from incompatibility issues and physical/chemical degradation, preventing loss while maintaining delivery efficiency.
Solution Approach 2:
Encapsulation within delivery particles changes the physical parameters of the benefit agent, protecting it from loss due to its inherent physical or chemical characteristics. The particle structure maintains stability and prevents premature release or degradation.
