Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If all traffic is processed/transmitted with the fastest possible speed, then throughput is maximized, but power consumption increases and delay tolerance is ignored

Engineering Contradiction:
ImprovethroughputVSAvoidpower consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic control of CPU speed and transmission power based on real-time network conditions and application requirements. The system adjusts operating parameters dynamically rather than maintaining fixed high-speed operation, allowing throughput optimization while reducing power consumption when maximum speed is not required.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes key parameters including CPU speed, transmission power, and modulation coding based on network state and application delay tolerance. By varying these parameters adaptively, the system achieves optimal balance between throughput and power consumption for different traffic types.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If network selection, AMC, and transmission power are controlled independently considering only network environment, then control simplicity is maintained, but overall power consumption optimization is prevented

Engineering Contradiction:
Improvecontrol simplicityVSAvoidoverall power consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The patent merges previously independent control functions (network selection, AMC, transmission power control, and CPU speed management) into a unified control framework. This integrated approach considers interactions between all components simultaneously, enabling overall power consumption optimization while maintaining manageable complexity through centralized decision-making.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The control system performs multiple functions simultaneously: it selects networks, adjusts modulation coding, controls transmission power, and manages CPU speed based on a unified power consumption model. This multi-functional approach allows comprehensive optimization across all system components.

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

3Loss of time

If CPU speed is increased to process applications faster, then application response time is reduced, but power consumption of the terminal increases

Engineering Contradiction:
Improveapplication response timeVSAvoidterminal power consumption
Core Design Contradiction:
Loss of timeVSUse of energy by moving object

Solution Approach 1:

The system applies partial CPU power based on actual application needs rather than always operating at maximum speed. By matching CPU utilization to the specific requirements of running applications, the system reduces unnecessary power consumption while maintaining adequate response times.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The control system uses feedback from network conditions, application requirements, and power consumption models to dynamically adjust CPU speed. This closed-loop control ensures CPU operates at appropriate speeds to meet application response requirements without excessive power consumption.

Inventive Principle:
Principle #23Feedback
