Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an ionic conductive agent is added to an insulative resin to impart electroconductivity, then electroconductivity is improved, but the ionic conductive agent migrates to the resin surface over time causing bleeding and contamination
Solution Approach 1:
The patent combines the ionic conductive agent with a polyisocyanate compound through chemical reaction to form a crosslinked structure. This merging of the conductive agent into the resin matrix prevents migration while maintaining electroconductivity, directly resolving the bleeding issue.
Solution Approach 2:
The invention creates a composite material system where the ionic conductive agent is chemically bonded with polyisocyanate and incorporated into the resin matrix. This composite structure ensures the conductive agent remains fixed within the resin, eliminating surface migration while preserving electroconductivity.
2Reliability
If conventional ionic conductive agents are used, then electroconductivity can be achieved, but reactivity with the resin is insufficient limiting applications
Solution Approach 1:
The patent changes the chemical parameters of the conductive agent by selecting specific ionic conductive agents with functional groups that can react with polyisocyanate. This parameter change enables chemical bonding and crosslinking, significantly improving reactivity with the resin and expanding application versatility.
Solution Approach 2:
The polyisocyanate compound acts as an intermediary that chemically bridges the ionic conductive agent and the resin matrix. This intermediary enables strong chemical bonding and crosslinking, enhancing reactivity and ensuring the conductive agent is firmly integrated into the resin structure.
