Peripheral Device Power Saving via LED State Transition

Solution Overview

Problem

Peripheral devices in wireless operation mode face significant power consumption challenges due to LED light effects, which shorten battery life and operation time, necessitating effective power saving methods to extend usage.

Innovation Solution

A power saving method that transitions peripheral devices through idle, power saving, and suspend modes based on startup and wakeup events, adjusting light source states to minimize power consumption, including entering low or off states for light sources outside operation regions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the peripheral device provides LED light effects to enhance user experience, then the user experience is improved, but the power consumption increases

Engineering Contradiction:

Improveuser experienceVSAvoidpower consumption

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic action by transitioning the peripheral device between idle mode (with LED light effects) and power saving mode (without LED light effects) based on user interaction detection. The device provides dazzling LED light effects during active use, then periodically switches to power saving mode when no startup trigger events are detected, and returns to idle mode when events are detected, creating a cyclic pattern that balances user experience with power conservation.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The patent applies dynamics by making the LED light effects adjustable and conditional rather than static. The system dynamically changes the state of light sources based on operational conditions - fully active during user interaction, partially active or inactive during idle periods. This dynamic adjustment allows the device to adapt its power consumption characteristics to actual usage patterns while maintaining user experience during active use.

Inventive Principle:

Principle #15Dynamics

2Illumination intensity

If the peripheral device operates in wireless mode with continuous LED light effects, then the visual appeal is maintained, but the battery life is shortened

Engineering Contradiction:

Improvevisual appealVSAvoidbattery life

Core Design Contradiction:

Illumination intensityVSDuration of action of moving object

Solution Approach 1:

The patent implements periodic action by transitioning the peripheral device between idle mode (with LED light effects) and power saving mode (without LED light effects) based on user interaction detection. The device provides dazzling LED light effects during active use, then periodically switches to power saving mode when no startup trigger events are detected, and returns to idle mode when events are detected, creating a cyclic pattern that balances user experience with power conservation.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The patent applies local quality by differentiating the operational states of different light sources based on their location and function. The system identifies operation region light sources versus non-operation region light sources, and applies different control strategies - operation region light sources are activated during user interaction while non-operation region light sources are deactivated during idle periods. This localized quality control maintains visual appeal where needed while conserving battery life in less critical areas.

Inventive Principle:

Principle #3Local quality

3Adaptability or versatility

If the peripheral device switches from wired to wireless operation mode, then the operational flexibility is improved, but the power consumption management becomes more critical

Engineering Contradiction:

Improveoperational flexibilityVSAvoidpower consumption management

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic action by transitioning the peripheral device between idle mode (with LED light effects) and power saving mode (without LED light effects) based on user interaction detection. The device provides dazzling LED light effects during active use, then periodically switches to power saving mode when no startup trigger events are detected, and returns to idle mode when events are detected, creating a cyclic pattern that balances user experience with power conservation.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The patent applies self-service by enabling the peripheral device to automatically monitor its own operational state and autonomously transition between power modes without requiring external control. The device detects startup trigger events itself, determines when to switch between idle and power saving modes, and manages its own power consumption. This self-service capability provides operational flexibility while intelligently managing power consumption based on actual usage patterns.

Inventive Principle:

Principle #25Self-service

AI summary

A power saving method for a peripheral device in a wireless operation mode is provided. The power saving method at least includes the steps of allowing the peripheral device to enter an idle mode and judging whether the peripheral device receives a startup trigger event. In the idle mode, the light source in an operation region of the peripheral device is in an on state or a high-brightness state. If the peripheral device receives the startup trigger event, the peripheral device is switched from the idle mode to a power saving mode. In the power saving mode, the light source in the operation region of the peripheral device is in an off state or a low-brightness state. The peripheral device in the power saving mode consumes less electric power than the peripheral device in the idle mode.
