Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If heat treatment at 350°C or higher is applied, then electrical conductivity is improved, but the electrode becomes a firing type which is not suitable for certain applications
Solution Approach 1:
The patent changes the temperature parameter from conventional high-temperature firing (350°C or higher) to low-temperature processing (50-350°C), thereby achieving sufficient conductivity while maintaining non-firing type characteristics suitable for specific applications
2Reliability
If only heat treatment is applied without pressure, then the manufacturing process is simple, but sufficient electrical conductivity cannot be achieved
Solution Approach 1:
The patent merges heat treatment and pressure application into a combined processing step, where the conductive paste is heated to 50-350°C and simultaneously pressed with 10-1000 kN/m² pressure, achieving sufficient conductivity while maintaining process simplicity
Solution Approach 2:
The patent introduces pressure as a new parameter (10-1000 kN/m²) in combination with temperature control (50-350°C), changing the processing conditions to achieve both sufficient conductivity and process efficiency
3Reliability
If pressure of 10 to 1000 kN/m² is applied, then electrical conductivity is improved, but the equipment complexity increases
Solution Approach 1:
The patent specifies a pressure range of 10-1000 kN/m² that balances conductivity improvement with equipment feasibility, avoiding excessively high pressures that would require complex equipment while ensuring sufficient electrical properties
