Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sleep disordered breathing treatment systems, particularly those using positive airway pressure (PAP) therapy, lack automated solutions for wireless peripheral device charging and pairing, requiring user intervention and prone to spurious pairing in environments with multiple devices.
Innovation Solution
A near-field wireless coupling interface is established between a pressure generating device base unit and a wireless peripheral device for both charging and data transfer, enabling automatic pairing and reducing spurious connections by ensuring only docked peripherals can establish a pairing relationship.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual charging and pairing methods are used for wireless peripheral devices, then user control and device compatibility are maintained, but user intervention time and pairing error risk increase
Solution Approach 1:
The system enables automatic charging and pairing through near-field coupling detection. When a peripheral device is placed on the base unit, the system automatically detects the coupling, initiates charging, and establishes pairing without requiring user intervention, thus reducing time loss while maintaining reliability through automated verification protocols
Solution Approach 2:
The system implements feedback mechanisms where the base unit continuously monitors the coupling status between the peripheral device and charging contact. Based on this feedback, the system automatically adjusts charging parameters and pairing protocols to ensure accurate pairing while minimizing user intervention time
2Extent of automation
If automated near-field coupling pairing is implemented, then pairing speed and automation are improved, but risk of spurious pairing in multi-device environments increases
Solution Approach 1:
The system uses near-field coupling detection to create a localized pairing zone. Only devices physically placed on the base unit's charging surface can establish coupling, ensuring that automation occurs only in the intended local area and preventing spurious pairing with distant devices
Solution Approach 2:
The near-field coupling interface acts as an intermediary that must be physically established before automated pairing can occur. This intermediary mechanism ensures that even in multi-device environments, only the device in direct contact with the base unit can pair, eliminating spurious connections while maintaining high automation
3Ease of operation
If wireless peripheral devices are used with PAP therapy systems, then patient comfort and mobility are improved, but charging convenience and connection reliability deteriorate
Solution Approach 1:
The system merges the charging function with the existing PAP device base unit. The base unit's surface serves dual purposes as both the PAP control interface and the wireless charging surface, eliminating the need for separate charging equipment and simplifying the overall charging operation for patients
