Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed capacitor structure is used, then the manufacturing process is simple, but the capacitance cannot be adjusted to meet varying practical application requirements
Solution Approach 1:
The capacitor structure is divided into multiple capacitor banks, each with adjustable connections to capacitor plates. This segmentation allows selective activation of different capacitor units to achieve varying total capacitance values, resolving the contradiction between adaptability and complexity by enabling adjustment through modular configuration rather than redesigning the entire structure.
Solution Approach 2:
The patent implements dynamic capacitance adjustment by allowing selective electrical connection between capacitor banks and capacitor plates through controllable switches or connection mechanisms. This dynamic reconfiguration capability enables the capacitor structure to adapt its total capacitance value based on circuit requirements while maintaining a fixed physical structure, thus achieving adaptability without proportionally increasing structural complexity.
2Reliability
If the entire capacitor structure is redesigned to adjust capacitance, then the capacitance can be optimized, but the manufacturing complexity and time increase significantly
Solution Approach 1:
The capacitor structure is manufactured with pre-positioned capacitor banks and capacitor plates in a fixed physical arrangement. The adaptability for capacitance adjustment is built into the design through pre-established connection points and switchable pathways, allowing capacitance optimization to be achieved through electrical configuration rather than physical redesign. This preliminary structuring maintains manufacturing simplicity while enabling post-manufacturing flexibility.
Solution Approach 2:
The patent enables capacitance adjustment by changing electrical connection parameters (which capacitor banks connect to which plates) rather than changing physical structural parameters. This approach allows optimization of capacitance values for different applications while maintaining the same manufactured structure, thus improving reliability through parameter adjustment without increasing manufacturing complexity.
3Adaptability or versatility
If multiple capacitor configurations are provided for different applications, then the adaptability increases, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent designs a universal capacitor structure where a single physical configuration of capacitor banks and plates can serve multiple capacitance requirements through different connection configurations. This multi-functionality is achieved by providing switchable connection pathways that allow the same hardware to be configured for different total capacitance values, thus maintaining ease of operation while achieving high adaptability.
Solution Approach 2:
The capacitor structure incorporates self-service adjustment mechanisms where the selection of different capacitance values is achieved through automatic or semi-automatic connection switching based on detected circuit requirements. This reduces the operational burden on users while maintaining high adaptability, as the system can autonomously or semi-autonomously configure the appropriate capacitance without requiring complex manual reconfiguration.
