Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in reducing power consumption of home electronic devices while ensuring user privacy, as they require installing additional sensors to detect user presence, which can be intrusive.
Innovation Solution
A device and method that estimate user presence or absence in a given space based on user interaction or control information for home electronic devices, using sensors or communication links to detect the user's current state and control the power or operational state of multiple devices accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If sensors are used to detect user presence, then power consumption can be reduced by accurately detecting user state, but device complexity and privacy intrusion risk increase
Solution Approach 1:
The patent uses a server as an intermediary to process user presence detection. Instead of installing sensors in every home device, the server receives signals from existing devices (smartphones, tablets, computers) and determines user presence centrally. This mediator approach reduces the complexity of deploying sensors while maintaining accurate detection capability.
Solution Approach 2:
The patent creates a virtual copy of user presence detection by using communication signals from existing devices. Rather than physically detecting presence with sensors, the system copies presence information through network communications from devices the user already owns, eliminating the need for additional hardware installation.
2Loss of energy
If sensors are installed to detect user presence, then power saving management becomes possible, but user privacy is compromised due to data transmission
Solution Approach 1:
The server acts as a privacy-protecting intermediary that processes presence information without requiring local sensors in home devices. Existing devices communicate their status to the server, which then determines presence without collecting detailed user behavior data, thus reducing privacy intrusion while enabling power management.
Solution Approach 2:
The patent extracts the presence detection function from local devices and places it in the server. By taking out the detection capability from individual home devices and consolidating it centrally, the system eliminates the need for sensors in homes while maintaining the ability to manage power consumption based on user presence.
3Device complexity
If existing devices are used for presence detection, then device complexity is reduced, but measurement precision may be insufficient for accurate power management
Solution Approach 1:
The patent merges signals from multiple existing devices (smartphones, tablets, computers) to determine user presence. By combining data from various device types and their communication patterns, the system achieves high measurement precision without adding complexity at the local device level, as the server integrates information from multiple sources.
Solution Approach 2:
The system uses feedback from device signals to continuously update presence determination. Devices communicate their operational state to the server, which processes this feedback information to accurately determine user presence. This feedback mechanism ensures precise detection while maintaining simple device architecture, as existing devices simply report their status.
