Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical components are used in power distribution apparatus, then power distribution function is achieved, but excessive heat is generated leading to thermal failure risk
Solution Approach 1:
An insulating heat conduction member is introduced as an intermediary between the electrical component and the heat exchange member. This mediator transfers heat from the electrical component to the heat exchange member while maintaining electrical insulation, thus resolving the contradiction between heat dissipation needs and insulation requirements
Solution Approach 2:
The heat dissipation function is extracted from the electrical component itself and transferred to a dedicated heat exchange member through the insulating heat conduction member. This separates the electrical function from the thermal management function, allowing the electrical component to focus on power distribution while the heat exchange member handles heat dissipation
2Productivity
If heat exchange member is placed close to electrical component for heat dissipation, then heat dissipation efficiency is improved, but short circuit risk increases
Solution Approach 1:
The insulating heat conduction member serves as a mediator that enables thermal coupling between the electrical component and heat exchange member while maintaining electrical insulation. This allows the components to be positioned close together for efficient heat dissipation without creating a short circuit path
Solution Approach 2:
The insulating heat conduction member exhibits different thermal and electrical properties at different locations: it has high thermal conductivity to transfer heat effectively, while maintaining high electrical insulation properties to prevent short circuits. This local differentiation of material properties resolves the contradiction between heat dissipation and insulation
