Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless transmission is used for biosensor signals, then convenience and mobility are improved, but signal noise contamination and interference increase
Solution Approach 1:
The patent introduces an intermediary interface device that converts biosensor signals into a format compatible with mobile device connectors. This mediator enables wired connection benefits (noise-free transmission) while maintaining the convenience of using existing mobile devices for monitoring.
2Ease of operation
If wireless transmission is used for biosensor signals, then mobility is improved, but power consumption increases
Solution Approach 1:
The patent extracts the wireless transmission requirement from the biosensor connection by using wired connectors that leverage existing mobile device infrastructure. This eliminates the need for additional power consumption associated with wireless RF transmission while maintaining the ability to use mobile devices for monitoring.
3Reliability
If wired connection is used for biosensor signals, then signal reliability and security are improved, but device complexity increases
Solution Approach 1:
The patent makes the mobile device universal by utilizing its existing connectors (audio jack, USB, headphone jack) for biosensor signal reception. This approach avoids adding complexity by instead leveraging the multi-functional nature of these existing connectors that can handle audio, data, and power transmission.
4Ease of manufacture
If existing mobile connectors are used for biosensor interface, then cost is reduced and reliability is improved, but adaptability to different connector types is limited
Solution Approach 1:
The patent segments the interface solution into separate functional components: a biosensor interface module that can adapt to different connector types (audio, USB, headphone jack). This segmentation allows the system to maintain low cost by using existing connectors while improving adaptability through modular design that can interface with multiple connector types.

AI summary
A biosensor interface apparatus that utilizes pre-existing or standard electrical connectors of mobile devices such as smart phones, mobile media players, and tablets. The interface device transforms the input biosensor signals to compatible electrical signals for input to one or more of the mobile's connectors. That signals are then conducted via one or more input conductors in the connectors to the mobile's microprocessor, which may display or transmit the biosensor signals and derive further measurements from them.
