Solution Overview

Problem

Current power management techniques in mobile devices are inefficient, as they constantly drain power to maintain connections and communicate with peripheral devices, even when they are not in use, leading to unnecessary power depletion.

Innovation Solution

A power management system that includes a peripheral power management component, which uses observed attributes and adaptive power management schemas to dynamically set states for peripheral devices, such as activating or deactivating them based on usage patterns, to optimize power distribution and reduce unnecessary power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If power is constantly provided to peripheral devices to maintain connection and communication, then communication reliability is improved, but power consumption increases

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system dynamically adjusts the power state of peripheral devices based on their activity status and communication requirements. The power management component transitions devices between active, idle, and low-power states, making the power provision adaptive rather than static, thus maintaining communication reliability only when necessary while reducing overall power consumption.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the power state parameter of peripheral devices based on observed attributes and communication needs. By monitoring device activity and adjusting power parameters dynamically, the system maintains adequate communication reliability during active periods while significantly reducing power consumption during inactive periods.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If power is constantly provided to peripheral devices, then device functionality is improved, but power availability for other resources decreases

Engineering Contradiction:

Improvedevice functionalityVSAvoidpower availability

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The power management system dynamically allocates power to peripheral devices based on their current functionality requirements and observed usage patterns. By making power allocation adaptive rather than constant, the system ensures adequate power availability for devices that need it while freeing up power for other critical resources in the mobile device.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Instead of providing full power to all peripheral devices continuously, the system applies partial power action only when and where needed. This selective power provision maintains necessary device functionality while preventing excessive power consumption that would deplete available power for other resources.

Inventive Principle:

Principle #16Partial or excessive action

3Device complexity

If typical power management techniques are used, then simplicity is improved, but power management efficiency deteriorates

Engineering Contradiction:

Improvepower management simplicityVSAvoidpower management efficiency

Core Design Contradiction:

Device complexityVSLoss of energy

Solution Approach 1:

The power management component autonomously monitors peripheral device attributes, determines appropriate power states, and executes power allocation decisions without requiring complex user intervention or manual configuration. This self-service approach improves power management efficiency by making intelligent, context-aware decisions while maintaining operational simplicity for the user.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system implements feedback mechanisms by continuously observing peripheral device attributes and communication states, then using this information to adjust power allocation decisions. This closed-loop feedback approach significantly improves power management efficiency compared to open-loop typical techniques, enabling the system to respond adaptively to changing conditions and eliminate wasteful power consumption.

Inventive Principle:

Principle #23Feedback

AI summary

The invention relates to systems and or methodologies for intelligent and adaptive power management in mobile devices. A peripheral power management component can set peripheral devices to active or inactive based on one or more schemas. The schemas can be predetermined or generated by the peripheral power management component. In addition, an adaptive component can modify the schemas to reflect actual usage or changing trends for each peripheral device.
