Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional insulated separator materials are used, then the separator provides basic insulation, but the electrolyte saturation is insufficient leading to high internal resistance
Solution Approach 1:
The patent applies composite materials by combining agar (a gel-forming substance) with fiber materials (such as cellulose or synthetic fibers) to create an insulated separator with enhanced properties. The agar component absorbs and retains electrolyte effectively, while the fiber material provides structural integrity and porosity control, together achieving both high electrolyte saturation and low internal resistance that conventional single-material separators cannot achieve
2Productivity
If the insulated separator structure is optimized for ion migration, then ion conductivity improves, but mechanical strength may be compromised
Solution Approach 1:
The patent applies local quality by creating different regions within the separator with distinct properties: the agar-rich areas provide high ion conductivity and electrolyte retention, while the fiber-dense areas provide mechanical strength and structural support. This spatial differentiation of material properties allows the separator to simultaneously achieve excellent ion migration characteristics and sufficient mechanical integrity
