Wireless Communication Device Automatic Reconnection Using Stored Settings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication methods require users to perform manual reconnection operations, such as bringing devices into proximity, every time a wireless connection is reestablished, which is cumbersome and inconvenient.
Innovation Solution
A wireless communication system and method that stores setting data in a storage medium during the initial connection and uses this data to automatically reconnect devices without the need for manual input or proximity operations, utilizing non-contact communication for data transfer and storage of settings for reestablishing connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual reconnection operations are required every time wireless connection is released, then connection reliability is improved, but user convenience deteriorates
Solution Approach 1:
The patent applies preliminary action by storing connection setting data in advance in a storage medium during the initial connection phase. When reconnection is needed, the system retrieves and uses this pre-stored data automatically, eliminating the need for users to manually re-input settings. This resolves the contradiction by maintaining connection reliability through structured reconnection procedures while dramatically improving user convenience through automation.
2Speed
If non-contact communication is used for data transfer, then connection speed is improved, but operational complexity increases
Solution Approach 1:
The patent extracts the complex non-contact communication data transfer process into a separate, dedicated function. The system uses non-contact communication specifically for transferring connection setting data during initial setup, while subsequent reconnections rely on retrieving stored data through simpler operations. This extraction reduces operational complexity for users while preserving the speed benefits of non-contact communication where applicable.

AI summary
A communication device includes a control unit that establishes a wireless communication between a communication unit and an external device by using setting data received from the external device. The device also includes a data processing unit that stores the setting data in a storage unit before the wireless communication is released. Further, the device includes a power input unit that receives power from outside. A communication releasing unit releases the wireless communication between the communication unit and the external device. The control unit uses the setting data stored in the storage unit at a time of re-performing a wireless communication between the communication unit and the external device. The communication releasing unit does not release the wireless communication when the power is being supplied via the power input unit even when a predetermined time has passed.
