VSEngineering Contradiction Analysis

1Temperature

If power consumption is controlled by distributing available power at a fixed ratio among modules, then heat generation can be suppressed, but performance degradation occurs uniformly across all modules without considering their specific usage conditions

Engineering Contradiction:
Improveheat generationVSAvoidmodule performance
Core Design Contradiction:
TemperatureVSProductivity

Solution Approach 1:

The patent implements dynamic power distribution by calculating individual coefficients for each module based on their current operation rates and usage conditions. Instead of using a fixed distribution ratio, the system continuously adjusts the power allocation coefficients (α1, α2, ..., αn) for each module according to their real-time operational state, enabling adaptive heat management that responds to changing workload conditions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent applies local quality by treating each module individually with its own power distribution coefficient rather than applying a uniform fixed ratio to all modules. Each module's power consumption is controlled based on its specific operation rate and usage conditions, allowing tailored thermal management for each component according to its local operational characteristics.

Inventive Principle:
Principle #3Local quality

2Productivity

If power is supplied to each device at a fixed ratio to maximize total performance, then overall system performance is optimized, but individual modules cannot receive appropriate power based on their specific load status

Engineering Contradiction:
Improvetotal performanceVSAvoidusage condition adaptability
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts power distribution coefficients based on real-time operation rates of each module. The coefficients (α1, α2, ..., αn) are calculated and updated according to current workload conditions, enabling the system to adapt power allocation to changing usage patterns while maintaining overall performance optimization.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent incorporates feedback mechanisms by monitoring the operation rates of each module and using this information to adjust the power distribution coefficients. The system continuously receives feedback on module performance and thermal state, then modifies power allocation accordingly to maintain optimal balance between performance and thermal management.

Inventive Principle:
Principle #23Feedback
