Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a battery is designed to be compact with high energy density, then the volume available for other systems increases, but temperature control becomes more difficult due to limited space for cooling systems
Solution Approach 1:
The patent combines the thin film serving as both mechanical support and electrical connection carrier with integrated temperature control functionality. The thin film acts as a multifunctional component that simultaneously provides structural support, electrical connectivity between battery cells, and thermal management through embedded temperature control devices, thereby achieving compact design without sacrificing temperature control capability
Solution Approach 2:
The thin film is designed as a universal component performing multiple functions: mechanical support for battery cells, electrical connection medium between cells, and thermal management platform. This multi-functionality eliminates the need for separate cooling systems, achieving both compactness and effective temperature control
2Reliability
If temperature control devices are added to ensure battery safety and performance, then battery safety improves, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent merges the temperature control functionality directly into the thin film structure that already serves as mechanical and electrical support. By integrating temperature sensors and control elements into the existing thin film rather than adding separate systems, the patent achieves improved safety while minimizing increases in overall device complexity
Solution Approach 2:
The thin film with integrated temperature control devices enables the battery to self-monitor and self-regulate its temperature. The system uses the thin film's own structure to detect temperature changes and activate cooling or heating as needed, reducing the need for external control systems and simplifying overall device architecture
3Adaptability or versatility
If a thin film with integrated temperature control is used, then the battery becomes more compact and multifunctional, but the manufacturing precision and assembly difficulty increase
Solution Approach 1:
The patent segments the thin film into functional zones with different properties: support sections providing mechanical strength, conductive tracks for electrical connection, and temperature control zones with embedded sensors and actuators. This segmentation allows each zone to be optimized and manufactured separately using appropriate techniques, then integrated into the complete thin film structure
Solution Approach 2:
The patent employs parameter changes in the thin film material properties and structure to achieve different functions in different regions. By varying thickness, conductivity, thermal properties, and material composition across the thin film, the patent creates a multifunctional component that can be manufactured using standard thin film deposition and fabrication techniques with controlled parameter variations
