Dynamic Setup Identifier for Wireless Sensor Pairing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In environments with multiple sensor and information systems, such as logistics centers or production lines, connecting portable secondary devices to the correct main device is a significant challenge due to the complexity of wireless communication connections.
Innovation Solution
A method is introduced where a setup identifier is used to establish a wireless communication connection between a main device and a secondary device, which is then discarded upon termination, ensuring that only desired connections are maintained, and re-establishing connections requires a new setup identifier, preventing unintended reconnections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless communication connections are used to connect secondary devices to main devices, then communication flexibility is improved, but connection reliability deteriorates due to difficulty in connecting to the correct main device
Solution Approach 1:
The patent applies preliminary action by generating and transmitting a setup identifier before the actual wireless connection is established. This identifier serves as a pre-arranged key that enables the secondary device to reliably connect to the correct main device without confusion in environments with multiple devices. The setup identifier is transmitted through various channels (optical, acoustic, wireless) prior to connection, ensuring reliable device pairing.
2Reliability
If setup identifiers are discarded after connection termination, then connection management reliability is improved by preventing unintended reconnections, but device complexity increases
Solution Approach 1:
The patent implements the discarding and recovering principle by automatically discarding the setup identifier after the communication connection is terminated. This ensures that the identifier cannot be reused for unintended reconnections, improving connection management reliability. The system recovers by generating a new setup identifier when a new connection is needed, maintaining security while managing the identifier lifecycle automatically without requiring complex manual intervention.
3Stability of the object's composition
If static identifiers like MAC addresses are used for connection, then connection stability is improved, but adaptability deteriorates as devices cannot easily connect to different main devices
Solution Approach 1:
The patent applies dynamics by transitioning from static identifiers (MAC addresses) to dynamic setup identifiers. The setup identifier can be changed for each connection session or as needed, allowing secondary devices to dynamically connect to different main devices while maintaining connection stability through the use of a predetermined identifier for each connection attempt. This dynamic approach enables both stability and adaptability.
