Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If software adjusts power consumption based on application scenarios over long time windows, then power consumption control is achieved, but timeliness is poor and cannot match dynamic needs of components

Engineering Contradiction:

Improvetime window for power consumption adjustmentVSAvoidtimeliness of power consumption control

Core Design Contradiction:

Loss of timeVSReliability

Solution Approach 1:

The patent uses hardware prediction circuits to predict future event parameters before they actually occur. The prediction unit calculates predicted values for upcoming time windows based on historical event data, allowing the system to prepare power consumption adjustments in advance rather than reacting after the fact. This preliminary action eliminates the delay inherent in software-based detection and adjustment.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent replaces the software-based power consumption control mechanism with a hardware-based prediction and control system. The event parameter detection, prediction, and power consumption control are all implemented through hardware circuits that operate in parallel and real-time, substituting the sequential software processing that caused the time window delay. This mechanical substitution enables immediate response to component needs.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If software control is used with long time windows, then power consumption adjustment is achieved, but the control cannot match the dynamic needs of various modules

Engineering Contradiction:

Improveability to match component needsVSAvoidresponse time to component changes

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent divides the power consumption control system into independent prediction units and control units for different components. Each prediction unit monitors event parameters specific to its associated component, and each control unit adjusts power consumption for its specific target. This segmentation allows each module to be controlled independently based on its own dynamic needs, rather than applying a unified software control policy to all components.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic, real-time prediction of event parameters using hardware circuits that continuously update predicted values based on current and historical data. The prediction period and control period can be dynamically adjusted to match the specific temporal characteristics of different components. This dynamic approach allows the system to adapt to changing component needs immediately, rather than relying on fixed software control intervals.

Inventive Principle:

Principle #15Dynamics

3Reliability

If hardware prediction circuits are used with shorter periods, then timeliness is improved, but system complexity increases

Engineering Contradiction:

Improvetimeliness of power consumption controlVSAvoidcomplexity of prediction and control system

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a prediction unit as an intermediary between event detection and power consumption control. This prediction unit acts as a buffer that processes event parameters and generates predicted values that are then used by control units. The prediction unit simplifies the overall system architecture by separating the complex prediction logic from the control logic, allowing each to be optimized independently while maintaining real-time performance.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent designs the prediction unit and control units with universal functionality that can handle multiple types of event parameters and control different components through standardized interfaces. The prediction circuit uses general-purpose calculation logic that can adapt to various component types without requiring completely separate hardware for each component. This universality reduces overall system complexity compared to having dedicated specialized circuits for each component type.

Inventive Principle:

Principle #6Universality (Multi-functionality)
