Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If dedicated heat dissipation components (holding member, heat dissipation member) are added to release heat from the circuit protection component, then heat releasing property is improved, but the number of components increases and device complexity worsens

Engineering Contradiction:

Improveheat releasing propertyVSAvoidnumber of components

Core Design Contradiction:

TemperatureVSDevice complexity

Solution Approach 1:

The patent merges the heat dissipation function into the housing body itself by providing a heat dissipation portion that is integrally formed with the housing. This eliminates the need for separate dedicated heat dissipation components while maintaining effective heat release from the circuit protection component. The housing body thus serves dual purposes: structural enclosure and thermal management.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The housing body is designed to perform multiple functions simultaneously: it provides mechanical protection for internal components, structural support for the connector, and acts as a heat dissipation pathway. The heat dissipation portion of the housing body conducts heat from the circuit protection component to the external environment, making the housing a multi-functional element that reduces overall component count.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Temperature

If dedicated heat dissipation components are added to externally release heat, then heat releasing property is improved, but assembly complexity and manufacturing difficulty worsen

Engineering Contradiction:

Improveheat releasing propertyVSAvoidassembly complexity

Core Design Contradiction:

TemperatureVSEase of manufacture

Solution Approach 1:

By integrating the heat dissipation portion directly into the housing body as a single molded component, the patent eliminates separate assembly steps for installing dedicated heat dissipation components. The heat dissipation structure is formed simultaneously with the housing during the molding process, significantly simplifying manufacturing and assembly operations.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The heat dissipation portion is pre-formed as an integral part of the housing body during the molding process, before final assembly. This preliminary formation of the heat dissipation pathway eliminates the need for subsequent assembly operations to install separate heat dissipation components, reducing both assembly complexity and manufacturing steps.

Inventive Principle:
