Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless device pairing techniques consume significant power and result in latency due to regular beacon transmission and reception, degrading user experience and reducing device operating time.
Innovation Solution
A method for predefined pairing of electronic devices using out-of-band communication, where identification and encryption information is exchanged via an Internet or cloud-based approach, allowing secure wireless connection establishment when devices are in range, reducing power consumption and latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If regular beacon transmission and reception is used for device detection, then devices can be paired wirelessly, but power consumption increases and latency increases
Solution Approach 1:
The patent applies preliminary action by pre-establishing pairing information through out-of-band communication (e.g., via QR code, NFC, or cloud service) before actual wireless connection is needed. This preliminary pairing setup stores authentication data and connection parameters in advance, so when devices need to connect, they can skip the lengthy beacon scanning and authentication process, directly using the pre-configured information to establish connection rapidly with minimal power consumption.

3Ease of operation
If traditional wireless pairing is used, then devices can connect, but security is vulnerable to sniffing attacks
Solution Approach 1:
The patent applies the intermediary principle by introducing a trusted third-party service (cloud-based pairing service or out-of-band communication channel) as a mediator in the pairing process. This intermediary securely transmits pairing information between devices through a controlled channel that is resistant to eavesdropping. The pairing data is authenticated and encrypted by the intermediary service, making it extremely difficult for attackers to intercept or manipulate the pairing process, thus eliminating sniffing risks while maintaining ease of operation.
Data Source
AI summary
In order to reduce latency and overhead during the device discovery process, operations involved in pairing of two electronic devices may be predefined. In particular, when a user specifies a new electronic device in a list of their electronic devices, a computer provides a notification to these electronic devices. In response to the notification, a given one of the electronic devices generates encryption information and identification information for the given electronic device, and provides this encryption information and identification information to the new electronic device via a network (such as the Internet). Then, the new electronic device generates encryption information and identification information for the new electronic device, and provides this encryption information and identification information to the given electronic device via the network. This pairing information may subsequently facilitate secure wireless communication between the two electronic devices.
