Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing gas-generating materials are used, then the micro pump can be constructed, but the gas production amount per unit time is insufficient and storage stability is poor
Solution Approach 1:
The patent uses a composite material system comprising a gas-generating agent (azo or azide compound), tertiary amine, photosensitizing agent, and binder resin. This composite formulation enables simultaneous achievement of high gas production rate and storage stability, resolving the contradiction between productivity and reliability.
Solution Approach 2:
The patent optimizes the content ratios of each component within specific ranges: gas-generating agent 1-90 parts by mass, tertiary amine 0.1-50 parts by mass, photosensitizing agent 0.1-50 parts by mass, and binder resin 10-300 parts by mass. This parameter optimization enables the material to achieve both high gas production and storage stability.
2Ease of manufacture
If micro pump structure is simplified, then manufacturing is easier, but gas generation efficiency may be reduced
Solution Approach 1:
The patent combines multiple functional components (gas-generating agent, tertiary amine, photosensitizing agent, and binder resin) into a single integrated gas-generating material layer. This merging allows the micro pump to maintain high gas generation efficiency while simplifying the overall structure by eliminating the need for separate complex subsystems.
