Distributed Smart Home Interaction for Gateway-Free Whole-House Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current smart home systems lack true whole house intelligence, requiring users to physically interact with centralized control devices and failing to adapt to individual family members' needs, with systems often crashing if the gateway is removed and not providing personalized services.
Innovation Solution
A smart home system composed of human-computer interaction devices placed in specific rooms or regions, equipped with processing, communication, audio, and sensing units, allowing for autonomous control and management of connected products through artificial intelligence, enabling seamless control and adaptation to user demands across the home.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a centralized control device is used to control whole-house products, then control functionality is provided, but users must physically go to the device location to control products
Solution Approach 1:
The patent divides the centralized control system into multiple distributed human-computer interaction devices placed in different rooms and regions. Each device independently controls products in its local area, eliminating the need for users to travel to a central control location. This segmentation transforms the single-point control into multi-point distributed control, solving the accessibility problem.
Solution Approach 2:
The patent introduces wireless communication technology to add a new dimension of control accessibility. Users can control products remotely through wireless networks without physical presence at the control device location. This transforms control from spatially-constrained to spatially-free, allowing control from any location in the home.
2Ease of operation
If a gateway is used as central control in smart home systems, then system control is achieved, but the entire system crashes when the gateway is removed
Solution Approach 1:
The patent eliminates the single gateway dependency by segmenting the control function across multiple human-computer interaction devices. Each device can independently control products in its region without requiring a central gateway. This distributed architecture ensures system reliability even when individual devices are removed or fail.
Solution Approach 2:
The patent extracts the gateway component from the system architecture entirely, replacing it with direct peer-to-peer communication between human-computer interaction devices and products. This removal of the mandatory central gateway eliminates the single point of failure while maintaining full control functionality through distributed devices.
3Device complexity
If existing smart home systems are designed with centralized control, then system structure is simplified, but they cannot provide personalized services for different family members
Solution Approach 1:
The patent segments the user profile and control authority across multiple human-computer interaction devices, with each device potentially associated with different users or user groups. This allows different family members to have personalized experiences at different locations without requiring complex centralized user management.
Solution Approach 2:
The patent enables each human-computer interaction device to have local customization capabilities, allowing different devices to provide different services tailored to the users who frequent those areas. This local quality approach provides personalized services distributed throughout the home rather than through a single centralized point.
4Ease of operation
If mobile phone assistance is used for product control, then remote control is enabled, but the control mode is backward and not truly intelligent
Solution Approach 1:
The patent implements intelligent automation where the human-computer interaction devices automatically detect user presence, preferences, and needs, then autonomously control products without requiring manual mobile phone commands. The system serves itself by learning and adapting to user behaviors, providing true intelligence rather than merely remote control capability.
Solution Approach 2:
The patent incorporates feedback mechanisms where human-computer interaction devices continuously monitor user interactions and product states, then use this feedback to automatically adjust control strategies and personalize services. This closed-loop feedback system enables intelligent adaptation rather than simple remote command execution.
