Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If base station operates in normal mode with full transmission and reception functions, then service quality and communication reliability are maintained, but power consumption increases

Engineering Contradiction:

Improvebase station power consumptionVSAvoidcommunication reliability

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

The base station dynamically switches between normal operation mode and energy saving mode based on traffic conditions and service requirements. The operation mode is adjusted in real-time to balance power consumption and communication reliability, allowing the system to adapt to varying load conditions while maintaining service quality when needed.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the operational parameters of the base station by adjusting transmission power levels, reception sensitivity thresholds, and resource allocation configurations when transitioning between modes. These parameter changes enable the base station to reduce power consumption in energy saving mode while still maintaining adequate communication functionality.

Inventive Principle:

Principle #35Parameter changes

2Loss of energy

If base station deactivates transmission and reception functions to save power, then energy consumption is reduced, but service provision capability deteriorates

Engineering Contradiction:

Improvenetwork energy consumptionVSAvoidservice provision capability

Core Design Contradiction:

Loss of energyVSProductivity

Solution Approach 1:

The base station implements periodic monitoring of traffic conditions and service demands, switching between normal and energy saving modes in regular intervals. This periodic operation allows the system to capture energy savings during low-traffic periods while ensuring service capability is restored when traffic demands increase, thus reducing overall energy consumption without permanently sacrificing productivity.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system employs feedback mechanisms where the base station continuously monitors service quality metrics, traffic load, and energy consumption levels. Based on this feedback, the operation mode is automatically adjusted - when service demands exceed thresholds, the system transitions from energy saving mode back to normal mode, ensuring that energy reduction does not compromise essential service provision.

Inventive Principle:

Principle #23Feedback

3Use of energy by stationary object

If base station operates in energy saving mode, then power consumption is reduced, but communication performance and transmission rate decrease

Engineering Contradiction:

Improvebase station energy usageVSAvoidtransmission rate

Core Design Contradiction:

Use of energy by stationary objectVSSpeed

Solution Approach 1:

The base station segments its operational functions into critical services that must be maintained and non-critical services that can be reduced or suspended. In energy saving mode, only essential communication functions operate at reduced capacity, while non-essential high-speed transmission functions are deactivated. This segmentation allows energy reduction without completely sacrificing transmission capability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The base station is designed with multi-functional capability that allows it to operate effectively in both normal and energy saving modes. The same hardware infrastructure supports multiple operational states, enabling the system to provide adequate service at reduced transmission rates in energy saving mode, and full-service high-speed operation when needed, using the same physical resources.

Inventive Principle:

Principle #6Universality (Multi-functionality)
