Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple power sources and output converters are used to distribute DC power, then power distribution capability is improved, but device complexity and heat dissipation problems worsen

Engineering Contradiction:

Improvepower distribution capabilityVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple output converters (DC/DC converters for different power sources) into a single integrated converter unit. This merging approach maintains the ability to distribute power from multiple sources while reducing overall system complexity and improving heat dissipation by consolidating components rather than having separate converters for each power source.

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If multiple heat-generating output converters are provided on a distribution board, then power distribution capability is improved, but heat dissipation property worsens

Engineering Contradiction:

Improvepower distribution capabilityVSAvoidheat dissipation property

Core Design Contradiction:

Adaptability or versatilityVSTemperature

Solution Approach 1:

Multiple output converters are merged into a single integrated converter unit with unified heat dissipation structures. This consolidation reduces the total heat-generating components distributed across the board and allows for more effective thermal management through centralized cooling solutions.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces heat dissipation fins that extend in the vertical dimension, increasing the heat dissipation surface area without occupying more horizontal space on the distribution board. This dimensional approach allows effective heat rejection while maintaining compact system layout.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If multiple AC/DC converters are used to handle varying load amounts, then power supply adaptability is improved, but device complexity and cost increase

Engineering Contradiction:

Improveload adaptabilityVSAvoidconverter quantity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a dynamic load sharing mechanism where a single integrated converter unit can dynamically adjust its operation to handle varying load amounts. The converter automatically distributes power conversion tasks among its internal modules based on real-time load conditions, eliminating the need for multiple fixed-capacity converters and reducing system complexity.
