Peer-to-Peer Power Control Device Bypassing Central Access Point
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Wi-Fi home automation systems require a central Access Point for communication, making them vulnerable to failure if the Access Point is disabled and prone to data latency due to overload, limiting the mobility and flexibility of device control.
Innovation Solution
A power control device that plugs into a standard mains outlet and communicates via a short-range wireless link with a smartphone or tablet acting as a controller, using Wi-Fi Direct technology to establish a peer-to-peer connection, allowing for independent control of electrical devices without the need for a central hub.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a central Access Point is used for Wi-Fi communication, then network infrastructure is established, but system reliability deteriorates when the Access Point is disabled or overloaded
Solution Approach 1:
The patent segments the centralized Wi-Fi network into multiple peer-to-peer communication links between controller devices and controlled devices. Each device establishes independent wireless connections without relying on a central Access Point, thereby eliminating the single point of failure and improving system reliability.
Solution Approach 2:
The patent extracts the central Access Point from the communication architecture and replaces it with direct peer-to-peer connections. By removing the mandatory central hub, the system eliminates the vulnerability to Access Point failures and overloads while maintaining wireless communication functionality.
2Ease of operation
If all communications pass through the Access Point, then network management is simplified, but data latency increases due to overload
Solution Approach 1:
The patent divides the communication path into direct peer-to-peer links between controller and controlled devices, eliminating the mandatory routing through the Access Point. This segmentation reduces the number of hops and intermediate processing steps, thereby decreasing data latency while maintaining simplified network management through direct connections.
3Adaptability or versatility
If conventional Wi-Fi networks are used, then wireless connectivity is provided, but mobility and flexibility of device control are limited
Solution Approach 1:
The patent extracts the requirement for fixed network infrastructure (Access Points and wired connections) and replaces it with mobile peer-to-peer wireless connections. Controllers can freely move and establish connections with controlled devices anywhere within wireless range, significantly improving mobility and flexibility without adding complex infrastructure.
