Solution Overview

Problem

Current power management in communications devices leads to inefficient use of resources, with either low device density due to maximum power consumption calculations or frequent performance impacts from sudden load increases, as power consumption is not dynamically adjusted to match actual needs.

Innovation Solution

A method and apparatus that group devices into clusters, set dynamic power consumption thresholds, and adjust these thresholds based on current consumption levels using a formula that balances excess and shortfall power across devices, ensuring optimal resource allocation and performance without overloading.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If power consumption ceiling values are set for each device independently, then device performance is protected from overconsumption, but resource utilization efficiency decreases when total power budget is not fully used

Engineering Contradiction:
Improvedevice performance protectionVSAvoidpower budget utilization efficiency
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent combines individual device power ceiling management with group-level power budget management. The management module monitors both individual device power consumption and total group power consumption, allowing coordinated adjustment of power ceilings across multiple devices to optimize overall power budget utilization while maintaining individual device protection.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent implements dynamic adjustment of power consumption ceiling values based on real-time monitoring of actual power consumption and service requirements. The management module can increase or decrease power ceilings for individual devices or groups of devices dynamically, allowing the system to adapt to changing load conditions and fully utilize the power budget when available.

Inventive Principle:
Principle #15Dynamics

2Loss of energy

If power consumption ceiling values are set high to maximize resource utilization, then power budget can be fully used, but device performance may be affected when sudden load increases occur

Engineering Contradiction:
Improvepower budget utilization efficiencyVSAvoiddevice performance stability
Core Design Contradiction:
Loss of energyVSReliability

Solution Approach 1:

The patent implements a feedback mechanism where the management module continuously monitors actual power consumption of devices and compares it with the power consumption ceiling values. Based on this feedback, the system can dynamically adjust ceiling values - increasing them when power consumption is below the ceiling and service requirements demand more power, or maintaining them when approaching the limit, thus balancing resource utilization with performance stability.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent changes the power consumption ceiling parameter dynamically based on monitored conditions. The management module can adjust the ceiling value for individual devices or groups of devices according to actual power consumption patterns and service requirements, allowing the system to maximize power budget utilization while responding to sudden load increases without compromising device performance.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If power consumption is calculated based on maximum power consumption, then overcurrent protection is ensured, but device density and space utilization are limited

Engineering Contradiction:
Improveovercurrent protectionVSAvoiddevice density
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent replaces static maximum power consumption calculations with dynamic power consumption monitoring and adaptive ceiling management. The system monitors actual power consumption in real-time and adjusts power ceiling values dynamically, allowing devices to operate at higher average power levels while maintaining safety margins through the ceiling mechanism, thus increasing device density without compromising overcurrent protection.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the power consumption parameter from a fixed maximum value to a dynamic ceiling value that adapts to actual consumption patterns. By setting power ceilings based on monitored actual consumption rather than theoretical maximums, the system allows higher device density while maintaining overcurrent protection through the adaptive ceiling mechanism that responds to real-time power usage.

Inventive Principle:
Principle #35Parameter changes

4Loss of energy

If power consumption is reduced to meet power budget constraints, then power budget compliance is achieved, but device performance and service quality deteriorate

Engineering Contradiction:
Improvepower budget complianceVSAvoidservice processing capability
Core Design Contradiction:
Loss of energyVSProductivity

Solution Approach 1:

The patent applies different power management strategies to different devices or groups of devices based on their individual characteristics and service requirements. The management module can set customized power ceiling values for each device or group, allowing devices with critical service requirements to maintain higher power consumption while less critical devices operate at lower levels, thus achieving power budget compliance without uniformly degrading service quality.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent implements dynamic power ceiling adjustment that responds to actual service requirements and power consumption patterns. When services require higher performance, the system can temporarily increase power ceilings for affected devices while monitoring overall budget compliance. This dynamic approach allows the system to maintain power budget compliance while preserving service quality during periods of high demand.

Inventive Principle:
Principle #15Dynamics
