Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the smart circuit breaker uses an integrated structure of the product body and smart electronic unit, then the structural integrity is improved, but the replacement cost increases when parts are damaged

Engineering Contradiction:
Improvestructural integrityVSAvoidreplacement cost
Core Design Contradiction:
Stability of the object's compositionVSEase of repair

Solution Approach 1:

The circuit breaker is divided into separate modular components: the circuit breaker body and the smart module, connected through a detachable connector. This segmentation allows the smart module to be replaced independently without replacing the entire circuit breaker, reducing replacement costs while maintaining structural integrity through the connector design.

Inventive Principle:
Principle #1Segmentation

2Ease of manufacture

If the smart circuit breaker uses an integrated structure, then the manufacturing simplicity is improved, but the application scenario diversification is limited

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidapplication scenario diversification
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

By segmenting the circuit breaker into a standard body and interchangeable smart modules, the design enables different smart modules to be developed for different application scenarios while using the same proven circuit breaker body, thus diversifying applications without repeating manufacturing processes.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The circuit breaker body is designed as a universal platform that can accommodate multiple types of smart modules through the standardized connector interface. This universality allows a single circuit breaker body design to serve multiple application scenarios by simply changing the smart module.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of repair

If the circuit breaker body and smart module are detachably connected, then the module replacement flexibility is improved, but the device complexity increases

Engineering Contradiction:
Improvemodule replacement flexibilityVSAvoiddevice complexity
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

A connector is introduced as an intermediary component between the circuit breaker body and the smart module. This connector simplifies the detachable connection by providing a standardized interface with guide grooves and engagement features, making the replacement process straightforward while managing the complexity of the detachable connection mechanism.

Inventive Principle:
Principle #24Intermediary (Mediator)
