Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If perfume microcapsules are incorporated into detergent powder, then olfactive performance and fragrance longevity are enhanced, but mechanical resistance and stability during high-shearing manufacturing processes deteriorate
Solution Approach 1:
The invention uses a composite granulated powder structure consisting of a water-soluble polymer matrix (such as starch or maltodextrin) combined with encapsulated oil containing perfume. This composite structure provides both mechanical strength to withstand manufacturing processes and controlled fragrance release, resolving the contradiction between durability and olfactive performance.
Solution Approach 2:
The invention optimizes the oil content parameter to a specific range (5-30% by weight, preferably 10-20%) within the granulated powder. This parameter optimization ensures sufficient fragrance loading while maintaining adequate mechanical strength and stability during high-shearing manufacturing processes, balancing fragrance longevity with mechanical resistance.
2Quantity of substance
If high oil content is used in granulated powder particles, then olfactive performance is improved, but particle stability and resistance to abrasion during manufacturing deteriorate
Solution Approach 1:
The invention establishes an optimal oil content range of 5-30% by weight (preferably 10-20%) in the granulated powder. This parameter optimization balances fragrance quantity with particle stability, ensuring sufficient perfume loading while maintaining mechanical strength and resistance to abrasion during high-shearing manufacturing processes.
Solution Approach 2:
The invention creates a structured granulated powder where oil is dispersed within a water-soluble polymer matrix rather than uniformly distributed. This local quality distribution ensures that fragrance is concentrated in specific regions while the polymer matrix provides structural integrity and stability throughout the particle, maintaining both olfactive performance and particle reliability.
3Stability of the object's composition
If extensive mixing is performed during manufacturing, then homogeneity of the detergent composition is improved, but particle breakage and perfume leakage increase
Solution Approach 1:
The invention pre-encapsulates perfume oil within a water-soluble polymer matrix to form stable granulated powder particles before the final mixing stage. This preliminary encapsulation protects the perfume from leakage during subsequent mixing operations, allowing extensive mixing to achieve homogeneity without significant perfume loss.
Solution Approach 2:
The water-soluble polymer matrix (such as starch or maltodextrin) forms a flexible protective shell around the encapsulated oil and perfume. This shell provides mechanical protection during high-shearing mixing while remaining soluble under washing conditions, enabling homogeneous mixing without excessive particle breakage or perfume leakage.
