Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless personal area networks (WPANs) face challenges in achieving low power consumption, low manufacturing cost, ad-hoc connectivity with little or no setup overhead, security, and high bandwidth for efficient data transfer, particularly in supporting high-speed applications like video/audio streaming and real-time communications.
Innovation Solution
The implementation of a hybrid solution using ultra-low power radios in collaboration with high-speed networks like 3G, 4G, LTE, and Wi-Fi, enabling devices to broadcast an intent to share data using low-power protocols and connect to a cloud server via high-speed protocols for secure, high-bandwidth data sharing without the need for traditional pairing or shared networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional wired data transfer or manual data collection is used, then data transfer can be achieved, but device complexity and ease of operation are reduced
Solution Approach 1:
The patent replaces manual data collection methods with automated wireless communication systems. Devices automatically broadcast their identity and capabilities, and data transfer is initiated and managed through software protocols rather than physical connection or manual intervention, thereby improving ease of operation while managing device complexity through standardized protocols
Solution Approach 2:
The system enables devices to automatically discover and connect to each other without manual configuration. The first device broadcasts its identity and the second device automatically responds, with the cloud server facilitating the connection setup, eliminating the need for user intervention in the data transfer process
2Productivity
If high-speed wireless protocols are used for data transfer, then bandwidth is improved, but power consumption increases
Solution Approach 1:
The patent segments the communication process into two distinct phases: discovery/broadcasting using low-power protocols, and actual data transfer using high-speed protocols. The first device uses ultra-low power radio to broadcast its identity, and only activates high-speed wireless communication when a connection is established and data transfer is actually needed, thereby achieving high productivity when required while minimizing power consumption during idle periods
Solution Approach 2:
The system uses periodic broadcasting at low power intervals to maintain connectivity awareness without continuous high-power transmission. The first device periodically broadcasts its identity using ultra-low power radio, and high-speed data transfer occurs only when triggered by a successful connection event, creating a rhythm of low-power monitoring punctuated by high-power data transfer when necessary
3Ease of operation
If ad-hoc networking with minimal setup is implemented, then ease of operation is improved, but security may be compromised
Solution Approach 1:
The patent introduces a cloud server as an intermediary that facilitates secure connection establishment between devices. The server receives connection requests, verifies device identities, and manages the pairing process, thereby maintaining security through centralized authentication while keeping the user experience simple with minimal setup overhead required on the end devices

AI summary
A first device broadcasts an intent to share data with a second device, using a first communications protocol, The first device connects to a cloud server using a second communications protocol, and shares the data with the second device on the cloud server when the second device is connected to the cloud server.
