Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a typical multilayer capacitor array is used, then the structure is simple and easy to manufacture, but it cannot simultaneously eliminate both differential-mode noise and common-mode noise
Solution Approach 1:
The patent applies multi-functionality by enabling a single multilayer capacitor array to perform both differential-mode noise elimination and common-mode noise elimination functions simultaneously. This is achieved through specific connection methods that allow the capacitor array to construct equivalent circuits capable of handling both types of noise, thus making one component serve multiple noise elimination purposes without requiring separate dedicated components for each noise type.
Solution Approach 2:
The patent utilizes parameter changes by varying the connection configuration of the capacitor array terminals to achieve different equivalent circuits. By changing how the terminals are connected (different connection methods), the same physical capacitor array can be adapted to eliminate different types of noise or provide different impedance characteristics, effectively changing the functional parameters of the device without altering its physical structure.
2Object-affected harmful factors
If multiple separate capacitor arrays are used to eliminate different noise types, then each noise type can be eliminated effectively, but the device complexity and number of components increase
Solution Approach 1:
The patent applies merging by combining the functions of multiple separate capacitor arrays into a single multilayer capacitor array. Instead of using separate arrays for differential-mode noise and common-mode noise elimination, the invention integrates both noise elimination capabilities into one unified capacitor array through appropriate terminal connections, thereby reducing the total number of components and simplifying the overall device structure while maintaining effective noise elimination for both types.
3Device complexity
If a single capacitor array is used, then the device complexity is reduced, but the ability to construct various equivalent circuits is limited
Solution Approach 1:
The patent applies dynamics by making the functional configuration of the capacitor array changeable through different connection methods. Although the physical structure remains static, the electrical configuration can be dynamically adjusted by selecting different terminal connection schemes, allowing the same capacitor array to construct various equivalent circuits adapted to different circuit board structures and noise elimination requirements, thus providing versatility without increasing physical complexity.
