Solution Overview

Problem

Large-sized electronic devices require high-power supply systems that are complex, difficult to maintain, and have poor cooling efficiency, making them unsuitable for meeting the demands of supersized display devices.

Innovation Solution

A power supply system comprising at least two independent power supplies connected in parallel, each simple in structure and easy to maintain, with a control module to manage power distribution based on the electronic device's electricity demand, allowing flexible control of power supply states.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If a single large-sized power supply system is used to meet high power demands, then power supply capacity is sufficient, but the structure becomes complex and difficult to maintain

Engineering Contradiction:
Improvepower supply capacityVSAvoidstructure complexity
Core Design Contradiction:
PowerVSDevice complexity

Solution Approach 1:

The power supply system is divided into multiple independent small-sized power supply modules instead of using a single large power supply. Each module can operate independently, and they work in parallel to meet the total power demand. This segmentation reduces the complexity of each individual module while maintaining sufficient overall power capacity.

Inventive Principle:
Principle #1Segmentation

2Power

If multiple components are integrated into one power supply to meet high power demands, then power capacity is sufficient, but the cooling effect becomes poor

Engineering Contradiction:
Improvepower supply capacityVSAvoidcooling efficiency
Core Design Contradiction:
PowerVSTemperature

Solution Approach 1:

By dividing the power supply into multiple separate modules, each module has its own cooling space and heat dissipation path. This prevents heat accumulation that would occur in a tightly integrated single power supply, thereby improving overall cooling efficiency while maintaining sufficient power capacity.

Inventive Principle:
Principle #1Segmentation

3Power

If a single large power supply is used, then power capacity is sufficient, but maintenance and management become more difficult

Engineering Contradiction:
Improvepower supply capacityVSAvoidmaintenance difficulty
Core Design Contradiction:
PowerVSEase of repair

Solution Approach 1:

The modular architecture allows each power supply module to be independently maintained and replaced. If one module fails, only that specific module needs to be serviced rather than the entire power supply system, significantly easing maintenance and management tasks while providing sufficient total power capacity.

Inventive Principle:
Principle #1Segmentation

4Power

If multiple transformers and rectifying filtering modules are integrated, then power capacity is sufficient, but the failure rate increases

Engineering Contradiction:
Improvepower supply capacityVSAvoidfailure rate
Core Design Contradiction:
PowerVSReliability

Solution Approach 1:

By distributing the transformers and rectifying filtering modules across multiple independent power supply modules, the failure of one module does not affect the others. This modular approach reduces the overall system failure rate while maintaining sufficient power capacity through the parallel operation of healthy modules.

Inventive Principle:
Principle #1Segmentation
