Engineering Contradiction Analysis
1Loss of energy
If heat dissipation is performed by making use of heat conduction using a fin-type heat sink, then heat dissipation efficiency is improved, but device size increases
Solution Approach 1:
The patent replaces the mechanical heat dissipation system (fin-type heat sink requiring physical contact and large surface area) with a radiation-based heat dissipation system that uses electromagnetic waves. The radiation sheet contains specific inorganic particles and polymerizable monomers that enable effective thermal radiation, allowing heat to be dissipated without mechanical conduction structures.
Solution Approach 2:
The patent changes the thermal management approach from conduction-based to radiation-based by modifying the material properties of the heat dissipation component. The radiation sheet is designed with specific composition (polymerizable monomer, inorganic particles, silane coupling agent) that enables it to radiate heat effectively at operational temperatures, fundamentally changing how heat is transferred from the heating element.
2Volume of stationary object
If heat dissipation is performed by making use of radiation, then device size is reduced, but heat dissipation efficiency may be insufficient
Solution Approach 1:
The patent employs a composite material system consisting of polymerizable monomer (A), inorganic particles (B), and silane coupling agent (C). This composite structure combines the advantages of organic polymers (flexibility, adhesion) with inorganic particles (thermal radiation properties), creating a material that achieves both compact size and effective heat dissipation through radiation.
Solution Approach 2:
The silane coupling agent acts as an intermediary between the polymerizable monomer and inorganic particles, ensuring strong bonding and effective heat transfer. This intermediary component enables the inorganic particles to effectively transfer heat to the polymer matrix, which then radiates the heat efficiently, solving the efficiency concern of radiation-based heat dissipation.
3Reliability
If conventional heat dissipation devices are used, then heat dissipation function is provided, but the device becomes large-sized requiring additional space
Solution Approach 1:
The patent merges the heat dissipation function directly into a compact sheet structure that can be applied directly to the heating element. The radiation sheet integrates thermal conduction (through the polymer matrix), thermal radiation (through inorganic particles), and adhesion (through silane coupling agent) into a single unified component, eliminating the need for separate fin-type heat sinks and mounting structures.
Solution Approach 2:
The patent uses a thin film structure made from curable paste that can be applied as a coating on the heating element. This flexible, thin-film approach replaces bulky rigid heat sinks, providing effective heat dissipation through radiation while occupying minimal space and conforming to the surface of the heating element.
