Solution Overview

Problem

Digital power supply devices face inefficiencies as individual power supply modules stop providing power when loads are not in operation, leading to suboptimal operating conditions.

Innovation Solution

A digital power supply device with a digital power supply controller, switch, and control module that allows power supply modules corresponding to inoperative loads to be dynamically rerouted to other active loads, enhancing usage and efficiency by combining power sources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If each power supply module provides power to a corresponding load separately, then the system structure is simple and easy to control, but the operating efficiency cannot achieve optimal condition when some loads are not in operation

Engineering Contradiction:
Improvecontrol simplicityVSAvoidoperating efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent implements dynamic load matching by enabling power supply modules to switch between different operational states (dedicated mode vs. shared mode) based on real-time load conditions. The controller dynamically adjusts the connection configuration through switching elements, allowing the system to adapt its power distribution topology optimally for current operating conditions, thereby resolving the contradiction between simple control structure and optimal operating efficiency.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent makes power supply modules universal by enabling them to serve both their dedicated loads and shared loads. Each power supply module can operate in multiple functional modes: providing power exclusively to its corresponding load, or sharing its output with other loads when the dedicated load is inactive. This multi-functionality allows the system to maintain simple modular architecture while achieving high operating efficiency through flexible resource allocation.

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

2Loss of energy

If power supply modules stop providing power when loads are not in operation, then the system avoids unnecessary energy consumption, but the overall usage and efficiency of the power supply device is reduced

Engineering Contradiction:
Improveenergy wasteVSAvoidusage efficiency
Core Design Contradiction:
Loss of energyVSProductivity

Solution Approach 1:

The patent implements a power recovery mechanism where power supply modules that would otherwise be idle (when their dedicated loads are inactive) are instead connected to provide power to active shared loads. The controller detects the operational state of each load and redirects power flow accordingly, effectively 'recovering' otherwise wasted power supply capacity and utilizing it to support system operations, thereby eliminating both energy waste and underutilization.

Inventive Principle:
Principle #34Discarding and recovering

Solution Approach 2:

The system implements self-service power allocation where the power supply device automatically adjusts its internal power distribution based on detected load conditions. The controller monitors the operational state of each load and autonomously reconfigures the power supply topology to match current demands, enabling the system to self-optimize its efficiency without external intervention while preventing both energy waste and underutilization.

Inventive Principle:
Principle #25Self-service

3Reliability

If multiple power supply modules operate independently, then the system has high reliability for each load, but the overall system efficiency decreases when some loads are inactive

Engineering Contradiction:
Improveload power supply reliabilityVSAvoidpower supply efficiency
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent implements conditional merging of power supply modules by maintaining independent dedicated power supply paths for reliability while enabling combination with shared power supply paths for efficiency. When dedicated loads are active, their power supply modules operate independently to ensure reliable power delivery. When dedicated loads are inactive, their power supply modules merge with the shared power supply network to support other loads, thereby achieving both high reliability and optimal efficiency through dynamic topology adjustment.

Inventive Principle:
Principle #5Merging (Combining)
