Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for fabricating insulating resin materials using core/shell particles require stringent control of temperature, pressure, and time, leading to limited molding conditions and increased energy costs, and often result in discontinuous shell layers due to the rigidity of inorganic shell layers.
Innovation Solution
The method involves swelling the macromolecular compound core with a good solvent before molding, allowing the core/shell particles to be molded into a compact without softening the core, and then removing the solvent to form a continuous shell layer, enabling flexible molding and reducing the need for high pressure and energy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If core/shell particles are molded by compression-molding, then insulating resin material can be formed, but temperature, pressure, and time control is required continuously, limiting molding conditions and increasing energy cost
Solution Approach 1:
The invention changes the physical state of the macromolecular compound from solid to swollen state by introducing a good solvent. This parameter change allows the material to be molded under much milder conditions without requiring continuous temperature and pressure control, thereby expanding molding flexibility while ensuring reliable shell layer formation.
Solution Approach 2:
The macromolecular compound is pre-swollen with a good solvent before molding occurs. This preliminary action softens the material in advance, allowing it to be molded into desired shapes without requiring stringent real-time control of temperature and pressure during the molding process itself.
2Reliability
If core/shell particles are molded by compression-molding, then insulating resin material can be formed, but large amount of energy is required for heating and pressurization, increasing fabrication cost
Solution Approach 1:
By changing the macromolecular compound to a swollen state through solvent absorption, the material becomes pliable at room temperature or with minimal heating. This eliminates the need for high-energy compression-molding processes, dramatically reducing energy consumption while maintaining shell layer integrity.
Solution Approach 2:
The invention replaces the mechanical compression-molding system with a chemical swelling process. Instead of using high pressure and heat to soften the material, a good solvent chemically swells the macromolecular compound, making it moldable without mechanical force, thereby substituting a high-energy mechanical process with a low-energy chemical process.
3Temperature
If inorganic filler particles are filled in resin to enhance heat conductivity, then heat conduction is improved, but large amount of inorganic filler must be filled, affecting resin properties
Solution Approach 1:
The invention creates a composite structure where inorganic filler particles are embedded within macromolecular compound cores, which are then coated with shell layers. This composite architecture allows heat conduction pathways to form through the inorganic fillers while the organic matrix maintains resin properties, achieving heat dissipation with optimized filler ratios.
Solution Approach 2:
The structure nests inorganic filler particles inside macromolecular compound cores, which are themselves enclosed by shell layers. This nested configuration maximizes the heat conduction efficiency of the inorganic fillers while minimizing the quantity needed, as the nested arrangement creates efficient heat transfer pathways without requiring high filler concentrations that would compromise resin properties.
