Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional batteries use traditional components without ceramic particles, then the battery structure remains simple, but the operability and discharge capabilities are limited
Solution Approach 1:
The patent introduces ceramic particles with specific parameters (size: 0.1-5mm, composition: alkali aluminum silicate with SiO2 40-70%, Al2O3 20-40%, Na2O 5-15%, K2O 2-10%) into the electrolyte to modify the chemical and physical parameters of the battery system, thereby improving operability without fundamentally changing the battery structure
Solution Approach 2:
The patent creates a composite electrolyte system by combining traditional liquid/gel electrolyte with ceramic particles (alkali aluminum silicate), forming a composite material that enhances battery performance. The ceramic particles serve as a new phase in the electrolyte, creating a composite structure that improves ionic conductivity and thermal stability
2Productivity
If ceramic particles are added to enhance discharge capabilities, then battery performance improves, but the manufacturing process becomes more complex
Solution Approach 1:
The ceramic particles are prepared in advance with controlled size (0.1-5mm) and composition before being added to the electrolyte. This preliminary preparation ensures consistent performance while simplifying the manufacturing process, as the particles can be directly incorporated without complex in-situ synthesis steps
Solution Approach 2:
The ceramic particles possess porous structures that facilitate ion transport, enhancing discharge capabilities. The porosity allows electrolyte penetration and increases surface area for electrochemical reactions, improving productivity without requiring complex dense structure fabrication
3Reliability
If loose ceramic particles are used in the electrolyte, then contact with both electrodes is achieved, but particle size and shape control becomes more difficult
Solution Approach 1:
The patent specifies a broad but controlled particle size range (0.1-5mm) and describes acceptable shape variations (spherical to irregular). This parameter specification balances the need for electrode contact with the practical difficulties of particle control, allowing manufacturing flexibility while ensuring functional reliability
Solution Approach 2:
The patent uses loose particles rather than requiring precise positioning or attachment to electrodes. This partial action approach (allowing particles to float and contact electrodes naturally) simplifies manufacturing by not requiring precise placement, while still achieving the necessary electrode contact for functionality
