Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional anti-corrosion methods (paper, liquid, grease, oil, powder) are used for metal packaging, then corrosion protection is provided, but packaging costs increase and productivity decreases due to additional processes
Solution Approach 1:
The patent combines corrosion inhibition function and antistatic function into a single coating layer. The coating contains conductive fillers (carbon black, graphite, metal particles) that provide both corrosion protection and static electricity dissipation, eliminating the need for separate anti-corrosion and antistatic treatments.
Solution Approach 2:
The coating composition is designed to perform multiple functions simultaneously: corrosion inhibition, antistatic protection, and UV resistance. This multi-functional coating reduces the number of separate treatment steps and materials needed in the packaging process.

3Reliability
If plastics are used as packaging material, then light weight and corrosion resistance are achieved, but static electricity problems occur due to electrical insulation properties
Solution Approach 1:
The patent changes the electrical parameter of the plastic packaging by incorporating conductive fillers (carbon black, graphite, metal particles) into the coating. This modifies the surface electrical resistance from insulating to conductive, allowing static electricity dissipation while maintaining the bulk plastic's corrosion resistance and light weight properties.
4Object-affected harmful factors
If conductive materials are added to plastics to improve electrical properties, then static electricity is reduced, but dispersibility of carbon materials deteriorates
Solution Approach 1:
The patent uses coupling agents or surface treatment agents as intermediaries between the carbonaceous fillers and the plastic matrix. These intermediaries improve the interfacial adhesion and dispersibility of the conductive fillers within the plastic, preventing agglomeration and ensuring uniform electrical conductivity throughout the packaging material.
