Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If functionalized carbons are used for energy storage, then capacitance is improved, but electrical conductance and meeting required standards deteriorate
Solution Approach 1:
The patent creates composite materials by combining two-dimensional organic polymers with activated carbon. The polymer component provides high electrical conductance through its conjugated structure, while the activated carbon provides high capacitance through its porous structure. This composite approach allows both requirements to be met simultaneously.
Solution Approach 2:
The patent changes the physical and chemical parameters of the electrode material by synthesizing two-dimensional polymers with specific molecular structures (such as pyromellitic diimide and hexaamino benzene derivatives) that inherently possess high electrical conductance. This structural parameter change enables the material to meet both conductance and capacitance standards.
2Reliability
If metal-based catalysts are used to synthesize polymers, then electrical conductance is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent extracts and eliminates metal-based catalysts from the synthesis process. Instead, it uses organic catalysts or catalyst-free methods to synthesize the two-dimensional polymers. This removal of metal catalysts simplifies the manufacturing process, reduces costs, and avoids trace metal contamination while maintaining the electrical conductance of the polymers.
Solution Approach 2:
The patent employs inexpensive organic catalysts or catalyst-free synthesis methods that are easier to handle and dispose of compared to metal-based catalysts. This approach reduces manufacturing complexity and cost while achieving the desired polymer conductance.
3Reliability
If complex synthesis processes are used to create advanced materials, then performance is improved, but ease of synthesis and scalability deteriorate
Solution Approach 1:
The patent segments the synthesis process into distinct, manageable steps: (1) synthesis of the two-dimensional polymer, (2) activation of carbon, and (3) combination to form the composite. Each step uses well-established, scalable techniques, making the overall process easier to execute and scale up while maintaining high performance.
Solution Approach 2:
The patent optimizes synthesis parameters such as temperature, pressure, and reaction time to achieve high-performance materials through straightforward processes. By carefully controlling these parameters, the patent maintains excellent performance while keeping the synthesis process simple and scalable.
