Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a fixed capacity switch is used in the power distribution system, then the switch can reliably handle the rated power, but the power distribution becomes inflexible when power demands change

Engineering Contradiction:
Improveswitch reliabilityVSAvoidpower distribution flexibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent applies the dynamics principle by transitioning from a fixed-capacity switch to a controllable switch whose capacity can be dynamically adjusted. The network management center remotely controls the switch capacity based on real-time power demands of IT equipment, allowing the system to adapt flexibly while maintaining reliability through controlled adjustment within safe limits.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements parameter changes by modifying the switch capacity parameter from a fixed value to an adjustable value. The network management center changes the switch capacity parameter according to the power consumption characteristics of IT equipment, enabling the system to adapt to different power demands without physical hardware changes.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If the switch capacity does not match the power demand, then the system becomes adaptable, but frequent replacement of switches and power cables increases engineering workload

Engineering Contradiction:
Improvepower demand adaptabilityVSAvoidengineering efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent replaces the mechanical system of physically replacing switches and power cables with an electronic control system. The network management center electronically adjusts the switch capacity and controls power distribution through software, eliminating the need for manual hardware replacement and significantly improving engineering efficiency.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system implements self-service by automatically monitoring power demands of IT equipment and autonomously adjusting switch capacity through remote control. The power distribution system adapts to changing demands without requiring manual intervention for hardware replacement, reducing engineering workload.

Inventive Principle:
Principle #25Self-service

3Extent of automation

If remote power control is implemented, then management efficiency improves, but system complexity increases

Engineering Contradiction:
Improveremote management capabilityVSAvoidcontrol system complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The patent applies universality by designing a network management center that performs multiple functions: monitoring power consumption of IT equipment, controlling switch capacity adjustment, and managing power distribution. This multi-functional approach consolidates control operations into a single centralized system, improving remote management efficiency while managing complexity through functional integration.

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