Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If a fixed power supply mode is used to supply power to peripherals, then the power supply mode is simple and stable, but the power distribution efficiency deteriorates because remaining power cannot be redistributed when system load power consumption changes

Engineering Contradiction:

Improvepower distribution efficiencyVSAvoidpower supply mode complexity

Core Design Contradiction:

Loss of energyVSDevice complexity

Solution Approach 1:

The patent implements dynamic power supply mode where the power supply capacity to peripherals is adjusted in real-time based on system load power consumption. The control unit continuously monitors system load and dynamically reallocates power between system load and peripherals, transforming the static fixed power supply mode into a dynamic adaptive mode that maximizes power distribution efficiency.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the power supply parameters (voltage and current) dynamically based on system load conditions. When system load power consumption decreases, the power supply parameters for peripherals are increased to utilize remaining power capacity, and vice versa. This parameter adjustment resolves the contradiction by adapting power distribution to actual system needs.

Inventive Principle:

Principle #35Parameter changes

2Power

If the power supply capacity to peripherals is increased, then more power is available for peripherals, but the system load power consumption may be insufficient causing wasteful power consumption

Engineering Contradiction:

Improvepower supply capacity to peripheralsVSAvoidwasteful power consumption

Core Design Contradiction:

PowerVSLoss of energy

Solution Approach 1:

The patent implements a feedback mechanism where the control unit continuously monitors system load power consumption and adjusts peripheral power supply capacity accordingly. When system load power consumption is low, the control unit increases power to peripherals; when system load power consumption is high, it reduces peripheral power. This closed-loop feedback control prevents wasteful power consumption by ensuring power is allocated according to actual system needs.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent performs preliminary assessment of system load power consumption before allocating power to peripherals. The control unit predicts future power consumption trends and proactively adjusts peripheral power supply capacity in advance, preventing both power waste and insufficient power supply scenarios.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If the power supply capacity to peripherals is reduced, then power is reserved for system load, but the remaining power cannot be utilized causing power distribution inefficiency

Engineering Contradiction:

Improvepower supply reliability for system loadVSAvoidpower distribution efficiency

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The patent dynamically changes power supply parameters based on system load conditions. When system load power consumption is low, the control unit increases voltage and current parameters for peripheral power supply, utilizing remaining power capacity. This parameter adaptation resolves the contradiction by ensuring power is not wasted while maintaining system load reliability.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The power supply system performs self-service by automatically monitoring its own power consumption status and autonomously reallocating power between system load and peripherals without external intervention. The control unit independently adjusts power distribution based on real-time system state, maximizing overall power utilization efficiency while ensuring system load reliability.

Inventive Principle:

Principle #25Self-service
