Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If active components are distributed within the polymer binder matrix, then the energetic material can be formed into a consolidated mass, but the homogeneity and mechanical properties are insufficient
Solution Approach 1:
A tackifying resin is introduced as an intermediary substance between the active components and the polymer binder matrix. The resin improves adhesion and dispersion of active components within the matrix, resulting in enhanced homogeneity and mechanical properties of the consolidated energetic material.
Solution Approach 2:
The invention creates a composite binder system consisting of polymer binder and tackifying resin. This composite material combines the structural properties of the polymer with the adhesive and dispersive properties of the resin, achieving both homogeneity and mechanical strength simultaneously.
2Ease of manufacture
If conventional mixing methods are used, then the processing is simple, but the energy required for mixing is high and homogeneity is poor
Solution Approach 1:
The tackifying resin acts as a mediator that facilitates better distribution of active components during mixing. This improves homogeneity while maintaining conventional mixing methods, thus keeping the process simple and energy-efficient.
3Device complexity
If the polymer binder matrix is used alone, then the formulation is simple, but the adhesive tack and mechanical properties are insufficient
Solution Approach 1:
The formulation evolves from a simple polymer binder matrix to a composite system containing polymer binder and tackifying resin. This composite approach enhances adhesive tack and mechanical properties while maintaining formulation simplicity through the synergistic interaction of the two components.
