Smart Home Appliance Presence Detection for Vacation Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional home appliances require manual adjustments to switch between operating modes, leading to potential energy wastage and increased costs due to users forgetting to change settings during periods of low or no usage.
Innovation Solution
A system and method that includes an interactive user interface, a timer, and a sensor to automatically adjust the operating mode of home appliances based on a predetermined time threshold, implementing a responsive action when the threshold is elapsed, such as switching to an energy-saving mode when the user is deemed absent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If manual adjustment is required to switch operating modes, then the appliance can be operated in different modes, but users may forget to change settings resulting in energy wastage
Solution Approach 1:
The appliance automatically detects user presence or absence and switches operating modes without requiring manual user intervention. The system monitors user interaction and autonomously transitions between normal operation mode and energy-saving mode, eliminating the need for users to manually adjust settings while preventing energy wastage.
Solution Approach 2:
The appliance incorporates sensors that detect user presence or absence and provide feedback to the control system. Based on this feedback, the system automatically adjusts operating modes - maintaining normal operation when users are present and switching to energy-saving mode when users are absent, thereby resolving the contradiction between manual operation requirements and energy efficiency.
2Loss of energy
If automatic operation is programmed into appliances, then energy savings can be achieved during periods of low usage, but users must perform manual adjustments to incorporate these settings
Solution Approach 1:
The appliance autonomously implements energy-saving operations by monitoring user presence through sensors and automatically switching modes without requiring users to manually program or adjust settings. The system self-manages the transition between operational states based on detected user activity patterns.
Solution Approach 2:
The appliance is pre-configured with automated presence detection and mode-switching capabilities that are ready to operate immediately. The system has built-in logic that automatically activates energy-saving modes when user absence is detected, eliminating the need for users to perform preliminary manual programming or configuration.
3Loss of energy
If users manually change settings before extended periods of low usage, then energy costs can be reduced, but users may forget to change settings resulting in excess energy expenditure
Solution Approach 1:
The appliance uses sensors to continuously monitor user presence and provides real-time feedback to the control system. When user absence is detected, the system automatically transitions to energy-saving mode, ensuring reliable energy cost reduction without depending on user memory or manual intervention. The feedback loop guarantees that energy-saving measures are implemented consistently.
Solution Approach 2:
The appliance autonomously manages its own energy consumption by detecting user absence and automatically switching to cost-effective operating modes. This self-service capability eliminates reliance on user action, ensuring that energy cost reduction is reliably achieved regardless of user forgetfulness or availability.

AI summary
A method of operating multiple home appliances within a smart home set up, including monitoring physical interactions with at least one appliance and measuring an amount of time since the interaction. The smart home network can activate a vacation mode including altering one or more operating modes of the appliance or alert a user via a mobile device to initiate a vacation mode.
