Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In environments with multiple portable and counterpart apparatuses, such as in a health club setting, it is challenging to determine which portable apparatus should be paired with a specific counterpart apparatus for communication, as multiple devices may be transmitting identifiers simultaneously, leading to confusion during the pairing process.
Innovation Solution
The use of induction-based technology to wirelessly transmit an identifier from the portable apparatus to the counterpart apparatus via a magnetic field, allowing the counterpart apparatus to recognize and pair with the correct portable device, followed by radio-based communication for data exchange using the established pairing protocol.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If radio transceivers execute pairing protocol in environments with multiple portable and counterpart apparatuses, then communication between devices is established, but it becomes problematic to identify which portable apparatus wishes to be paired with a specific counterpart apparatus
Solution Approach 1:
The patent introduces an intermediary mechanism using induction-based technology as a mediator between portable and counterpart apparatuses. This intermediary system transmits unique identifiers through magnetic fields, enabling reliable device identification and pairing selection in environments with multiple devices without requiring complex manual intervention
2Quantity of substance
If multiple portable apparatuses transmit identifiers simultaneously in crowded environments, then all devices can be detected, but confusion arises during the pairing process
Solution Approach 1:
The patent segments the identification process into two distinct phases: first, induction-based technology transmits unique identifiers through magnetic fields for reliable detection; second, radio-based communication completes the pairing protocol. This segmentation allows the system to handle multiple devices simultaneously while maintaining pairing accuracy by using different communication technologies for different purposes
