Innovation Solution
A physiological monitoring system comprising a biometric sensor device integrated into athletic apparel, a first handheld computing device, and a second handheld device, which operates in both slave and master modes for wireless communication, ensuring data transmission and storage even during communication disruptions, and compatibility with multiple devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If biometric data is transmitted wirelessly from sensor to handheld device, then data collection capability is improved, but data loss occurs when communication is interrupted
Solution Approach 1:
The sensor device stores biometric data in its internal memory buffer before transmission to the handheld device. This preliminary storage ensures that data is preserved even if communication is interrupted, allowing complete data sets to be transmitted when connectivity is restored.
Solution Approach 2:
The sensor device's internal memory acts as an intermediary buffer between data collection and transmission. This intermediary storage layer decouples the data collection process from the transmission process, ensuring data integrity regardless of communication status.
2Reliability
If sensor device is designed for specific handheld device compatibility, then communication reliability is improved, but adaptability to various devices is reduced
Solution Approach 1:
The sensor device is designed with universal communication capabilities that allow it to interface with multiple types of handheld devices (smartphones, tablets, computers, media players). The device can establish wireless connections using standard protocols, enabling a single sensor design to work across diverse device platforms without sacrificing communication reliability.
