Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If resistance and capacitor elements are integrated in a closed loop configuration, then device integration is achieved, but circuit design freedom is reduced

Engineering Contradiction:

Improvecircuit design freedomVSAvoidintegration structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The capacitor body is segmented into multiple independent external electrodes (first, second, third, and fourth external electrodes) that can be independently connected to different circuit nodes. This segmentation allows the resistance and capacitor elements to be connected in various configurations (series, parallel, or independent connections) rather than being constrained to a fixed closed loop structure, thereby resolving the contradiction between integration and design freedom.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a multi-dimensional electrode arrangement where external electrodes are positioned on different surfaces and orientations of the capacitor body. The first and second external electrodes are isolated in a length direction, while the third and fourth external electrodes are located between them. This spatial dimensionality enables flexible circuit board mounting and connection configurations, achieving both integration and design versatility.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If multiple external electrodes are provided on capacitor body surfaces, then connection flexibility is improved, but manufacturing complexity increases

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The capacitor body is designed with a universal multi-electrode structure where the first, second, third, and fourth external electrodes can serve multiple functions depending on the circuit requirements. These electrodes can be configured for series connections, parallel connections, or independent connections to resistance elements. This universal design achieves connection flexibility while using standard capacitor manufacturing processes, avoiding excessive manufacturing complexity.
