Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If power consumption is adjusted based on historical load status, then power consumption management is implemented, but significant delay occurs and adjustment effect is poor

Engineering Contradiction:
Improveadjustment delayVSAvoidadjustment accuracy
Core Design Contradiction:
Loss of timeVSReliability

Solution Approach 1:

The patent applies preliminary action by predicting future load status trends before they actually occur. The prediction module analyzes historical load data to forecast upcoming power consumption patterns, allowing the system to adjust power consumption proactively rather than reactively. This eliminates the delay inherent in waiting for historical data to fully manifest and enables timely power management adjustments.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback by continuously monitoring actual load status and comparing it with predicted trends. The system uses this feedback loop to refine its predictions and adjust power consumption dynamically. The feedback mechanism ensures that power management decisions are based on both historical patterns and real-time conditions, improving both responsiveness and accuracy.

Inventive Principle:
Principle #23Feedback

2Ease of operation

If terminal device is designed with slim and lightweight body, then portability is enhanced, but battery capacity and heat dissipation capability are limited

Engineering Contradiction:
ImproveportabilityVSAvoidbattery capacity
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The patent applies dynamics by implementing dynamic power consumption adjustment that adapts to changing operational conditions. Instead of using a fixed power management strategy, the system continuously monitors load status, predicts future demands, and adjusts power consumption in real-time. This dynamic approach allows the device to optimize battery usage during portable use scenarios while maintaining performance when needed, effectively extending battery life without increasing physical battery capacity.

Inventive Principle:
Principle #15Dynamics

3Productivity

If processor performance is adjusted without relying on load status, then efficiency of performance adjustment is improved, but resource waste may occur

Engineering Contradiction:
Improveperformance adjustment efficiencyVSAvoidresource waste
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The patent applies parameter changes by dynamically adjusting the energy performance preference parameter based on predicted load status. Rather than using fixed performance levels or simple load-based thresholds, the system modifies the energy performance preference parameter according to forecasted power consumption patterns. This allows fine-grained control over processor performance, optimizing the balance between responsiveness and energy efficiency by changing performance parameters proactively before load increases occur.

Inventive Principle:
Principle #35Parameter changes
