Engineering Contradiction Analysis
1Temperature
If a large amount of inorganic powder is added into resin to achieve high thermal conductivity, then thermal conductivity is improved, but processability deteriorates and mechanical properties are lost
Solution Approach 1:
The patent modifies the chemical structure parameters of the resin itself by introducing benzaldazine compounds with specific R1 groups (—NH2, —OH, or specific aromatic groups) to inherently increase thermal conductivity. This chemical parameter change allows achieving high thermal conductivity without relying on large amounts of inorganic powder, thus avoiding processability issues
Solution Approach 2:
The patent creates a composite polymer system by reacting benzaldazine compounds with diamine compounds, dianhydride compounds, or epoxy resins. This composite approach combines the thermal conductive properties of benzaldazine structures with the mechanical and processing advantages of the base resin, achieving both high thermal conductivity and good processability
2Temperature
If a large amount of inorganic powder is added into resin to achieve high thermal conductivity, then thermal conductivity is improved, but mechanical properties deteriorate
Solution Approach 1:
The patent changes the chemical composition parameters of the resin by incorporating benzaldazine compounds with specific functional groups. This chemical modification inherently enhances thermal conductivity at the molecular level, eliminating the need for excessive inorganic fillers that would compromise mechanical strength
Solution Approach 2:
The patent develops a composite polymer where benzaldazine compounds are chemically integrated with diamine or epoxy base materials. This creates a synergistic composite where the benzaldazine moieties provide thermal conductivity while the base polymer matrix maintains mechanical integrity, achieving both high thermal conductivity and preserved mechanical properties
3Temperature
If inorganic powder is added to improve thermal conductivity, then thermal conductivity is improved, but bonding surface quality deteriorates due to poor bonding and air barriers
Solution Approach 1:
The patent modifies the resin's chemical parameters by introducing benzaldazine compounds that provide inherent thermal conductivity. This eliminates the need for inorganic powder addition, thereby preventing bonding surface defects such as poor adhesion and air barrier formation while maintaining excellent bonding quality and reliability
