Low-Power Control Method for Smart Home Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart home devices face challenges in efficiently managing power consumption when multiple electronic devices are in use, leading to increased inconvenience and energy wastage, as existing solutions require manual settings for power-saving modes and lack adaptive control based on user interest levels.
Innovation Solution
A low-power control method that adjusts settings for electronic devices based on the user's interest level in other devices, determined by factors like interaction duration, power consumption, and content association, using a power control module to activate low-power settings dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If manual power-saving settings are implemented for each device, then power consumption can be reduced, but user convenience deteriorates due to multiple configuration steps
Solution Approach 1:
The system automatically detects user attention focus through camera-based eye tracking and interest level analysis, then autonomously activates or deactivates power-saving modes on appropriate devices without requiring any manual user configuration. The electronic devices self-adjust their power states based on real-time analysis of user behavior patterns.
Solution Approach 2:
The system continuously monitors user interaction patterns, eye gaze duration, and device usage metrics to dynamically adjust power-saving settings. When the system detects that user interest shifts to a different device, it provides feedback by automatically modifying power states, creating a closed-loop control system that adapts to changing user preferences in real-time.
2Loss of energy
If power-saving mode is activated automatically based on device usage, then energy efficiency improves, but system complexity increases due to additional sensors and processing requirements
Solution Approach 1:
A centralized power control module serves as an intermediary that receives interest level information from one or more electronic devices and coordinates power-saving activations across the system. This mediator architecture allows individual devices to remain relatively simple while achieving system-wide energy optimization through centralized decision-making.
Solution Approach 2:
The power control module performs multiple functions including receiving operation signals, determining effective devices, analyzing interest levels, and activating power-saving modes across different device types. This multi-functional component reduces overall system complexity by consolidating control logic in a single universal controller rather than requiring complex intelligence in each individual device.
3Productivity
If multiple electronic devices are used simultaneously, then user productivity improves, but power consumption increases due to multiple active displays
Solution Approach 1:
Instead of completely shutting down devices that are not the primary focus, the system applies partial power-saving measures by activating power-saving modes only on devices determined to have low user interest. This allows the system to maintain productivity by keeping necessary devices fully functional while applying energy-saving actions only where appropriate, avoiding excessive power reduction that would impact user workflow.
