Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If cement-based materials are used for building structures, then structural strength is provided, but electrical energy storage capacity is lost
Solution Approach 1:
The patent merges the structural function of cement-based materials with the energy storage function of battery components by integrating electrodes, electrolyte solution, and porous materials directly into the cement matrix, creating a multi-functional composite that simultaneously provides structural strength and electrical energy storage capacity
Solution Approach 2:
The invention creates a composite material system combining cement, porous materials (such as activated carbon or metal foams), conductive materials, and electrolyte solution to form a battery-integrated cement composite that exhibits both structural properties and electrochemical energy storage capabilities
2Quantity of substance
If battery components are integrated into cement structures, then electrical energy storage capacity is improved, but manufacturing complexity increases
Solution Approach 1:
The patent incorporates battery components (electrodes, porous materials, electrolyte) into the cement mixture before casting and curing, allowing the battery structure to be formed simultaneously with the cement structure rather than requiring separate assembly steps after construction
Solution Approach 2:
The cement mixture itself serves as the battery assembly medium, where the pouring and curing process automatically positions and secures the electrodes and other components within the cement matrix, eliminating the need for complex external assembly equipment and procedures
3Quantity of substance
If porous materials are added to cement mixture, then electrical energy storage is enabled, but curing process difficulty increases
Solution Approach 1:
The patent incorporates porous materials (such as activated carbon, metal foams, or porous ceramics) into the cement mixture to provide electrolyte retention spaces and increase surface area for electrochemical reactions, enabling electrical energy storage while maintaining workability during mixing and pouring
Solution Approach 2:
The invention adjusts key parameters including the water-to-cement ratio, porous material particle size distribution, and mixing time to optimize both the workability of the cement mixture during placement and the curing characteristics after placement, ensuring that energy storage functionality is achieved without excessive curing difficulty
