Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing sealants face a trade-off between void removal and temperature conditions, making it difficult to maintain both mass productivity and discharge ability over time, especially when sealants are stored and thawed.
Innovation Solution
A method that involves weighing and mixing components, followed by kneading, stirring, and defoaming, where the kneaded product is stirred at specific rotational speeds for predetermined times to achieve an arithmetic product within set limits, ensuring effective void removal and discharge ability, with the option to freeze the filled product for storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the stirring amount is increased to improve mass productivity, then productivity is improved, but the trade-off relationship between void conditions and temperature conditions breaks down, making it impossible to satisfy both void removal and discharge ability
Solution Approach 1:
The patent applies dynamics by making the stirring rotational speed variable rather than constant. The speed is adjusted based on the stirring time to maintain a constant arithmetic product (stirring rotational speed × stirring time). This dynamic adjustment allows the system to handle larger stirring amounts while maintaining optimal void removal and discharge ability, thereby improving mass productivity without sacrificing reliability.
Solution Approach 2:
The patent changes the parameter of stirring rotational speed as a function of stirring time. By establishing a relationship where the arithmetic product of stirring rotational speed and stirring time remains constant, the system can optimize the stirring process for different batch sizes. This parameter change enables processing of larger amounts while maintaining the same effectiveness in void removal and discharge ability.
2Reliability
If the stirring rotational speed is increased to improve void removal, then void removal ability is improved, but the stirring time must be reduced which may affect discharge ability
Solution Approach 1:
The patent applies dynamics by making the stirring rotational speed variable rather than constant. The speed is adjusted based on the stirring time to maintain a constant arithmetic product (stirring rotational speed × stirring time). This dynamic adjustment allows the system to handle larger stirring amounts while maintaining optimal void removal and discharge ability, thereby improving mass productivity without sacrificing reliability.

3Reliability
If the stirring time is extended to improve void removal, then void removal ability is improved, but the temperature increases due to Joule heat which may affect discharge ability

AI summary
A method for producing a sealant includes a weighing and mixing step (S01), a kneading step (S02), a stirring and defoaming step (S03), and a filling step (S04). In the weighing and mixing step (S01), a main component and a curing agent are weighed out and mixed together. In the kneading step (S02), the mixture mixed in the weighing and mixing step (S01) is kneaded. In the stirring and defoaming step (S03), the kneaded product kneaded in the kneading step (S02) is stirred and defoamed. In the filling step (S04), the kneaded product defoamed in the stirring and defoaming step (S03) is filled into a container. In the stirring and defoaming step (S03), the kneaded product is stirred under a condition in which a product of a stirring rotational speed at which the kneaded product is stirred and a stirring time for which the kneaded product is stirred is within a range from a product lower limit value to a product upper limit value that are predetermined according to a stirring amount of the kneaded product.
