Pre-Shipped Wireless Pairing via Non-Volatile Memory Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication settings for paired wireless devices, such as information processing devices and peripherals, require manual pairing by users upon initial setup, which can be inconvenient and lacks security measures to prevent information leakage.
Innovation Solution
A communication setting method where the storage control units in both devices store communication connection information before shipping, allowing for automatic pairing upon first startup, using non-volatile memory for secure storage and limited advertising for pairing to reduce information exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual pairing is required for wireless devices upon initial setup, then user control over connection is maintained, but user convenience deteriorates and setup time increases
Solution Approach 1:
The patent applies preliminary action by pre-storing communication connection information in both the information processing device and peripheral device before shipping. This advance preparation eliminates the need for manual pairing operations at the time of use, as the connection information is already in place and ready for automatic pairing upon first startup.
2Reliability
If communication connection information is stored in volatile memory, then easy access during operation is achieved, but security deteriorates due to risk of information leakage
Solution Approach 1:
The patent applies this principle by using non-volatile memory for storing communication connection information, which maintains security through persistent storage while being cost-effective. The non-volatile memory retains information without requiring continuous power, providing secure long-term storage that prevents information leakage while remaining economically viable.
3Reliability
If advertising for pairing is executed continuously, then ease of connection is improved, but information exposure increases and security deteriorates
Solution Approach 1:
The patent applies periodic action by limiting advertising for pairing to execute only within a specific time window from the first startup after shipping. This time-limited periodic advertising ensures connection reliability during the critical initial setup period while automatically stopping information exposure after the designated period, thereby preventing prolonged vulnerability to malicious access.

AI summary
A communication setting method of enabling a first communication device and a second communication device that are shipped together as a set and are compliant with common wireless communication to be connected to each other by the wireless communication includes a step in which a storage controller in the first communication device causes a storage in the first communication device to store, at a predetermined stage before the shipping, communication connection information that is issued for the first communication device and includes predetermined identification information used for the connection; and a step in which a storage controller in the second communication device causes a storage in the second communication device to store, at a predetermined stage before the shipping, the same communication connection information as stored in the storage in the first communication device.
