Solution Overview
Problem
Conventional solid or powdered additives in silicone compositions pose challenges such as dispersion in the air, inhalation risks, and uneven mixing, leading to inconsistent incorporation into curable silicone products.
Innovation Solution
A liquid additive delivery composition using a carrier like polyvinyl acetate or polyvinyl alcohol facilitates uniform mixing and incorporation of additives into curable silicone compositions, reducing environmental dispersion and inhalation risks, and allowing for easier measurement and handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If solid or powdered additives are used in silicone compositions, then the additive can be incorporated into the composition, but the additive may disperse in the air and pose inhalation risks
Solution Approach 1:
The patent changes the physical state of the additive from solid/powdered to liquid form. The additive is formulated as a liquid composition that can be mixed with the silicone composition, eliminating air dispersion and inhalation risks while maintaining ease of handling through liquid flow properties
Solution Approach 2:
The patent introduces a liquid carrier as an intermediary substance that dissolves or suspends the additive. This carrier medium allows the additive to be transported and mixed without direct contact with air, reducing inhalation hazards while facilitating easy measurement and incorporation into the silicone composition
2Manufacturing precision
If solid or powdered additives are used in silicone compositions, then the additive can be incorporated into the composition, but uneven mixing occurs
Solution Approach 1:
The patent changes the physical state of the additive from solid/powdered to liquid form. Liquid additives mix more uniformly with liquid silicone compositions through better wetting and dispersion, achieving homogeneous distribution without requiring complex mixing procedures or additional equipment
Solution Approach 2:
The patent formulates the additive as a liquid composition that is homogeneous with the silicone composition medium. This ensures uniform distribution of the additive throughout the composition, achieving consistent manufacturing quality without complex mixing processes
3Manufacturing precision
If liquid additive delivery composition is used, then uniform mixing and incorporation is achieved, but the composition includes additional components (polyvinyl acetate or polyvinyl alcohol)
Solution Approach 1:
The patent uses polyvinyl acetate or polyvinyl alcohol as intermediary carrier substances that facilitate uniform incorporation of the additive into the silicone composition. These carriers are specifically selected for their compatibility with both the additive and silicone matrix, enabling consistent distribution without significantly complicating the overall composition
Solution Approach 2:
The patent optimizes the concentration range of the liquid carrier (5-20% by weight) to achieve uniform mixing while minimizing the impact on the final product. This parameter optimization ensures that the added complexity of the carrier system does not excessively affect the silicone composition's final properties
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The liquid additive delivery composition ensures uniform distribution and mixing of additives within the silicone products, resulting in a more consistent cured product with improved texture and cure time, even at up to 15% by weight of polyvinyl acetate or polyvinyl alcohol.
Implementation Method 1
The liquid carrier may include one or both of polyvinyl acetate or polyvinyl alcohol
Implementation Method 2
