Solution Overview

Problem

Conventional methods for monitoring blood glucose levels in diabetics are inconvenient and infrequent, leading to delayed detection of hyperglycemic or hypoglycemic conditions, as diabetic patients often measure glucose levels only two to four times a day, missing critical time intervals and risking dangerous side effects.

Innovation Solution

A method for transmitting data between a first communication device associated with an analyte sensor and a second communication device, utilizing a transceiver with a two-way communication channel and authentication scheme, activating and deactivating the transceiver periodically to conserve power, and implementing various data processing and transmission strategies to ensure efficient and secure data exchange.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If continuous monitoring is implemented to improve detection timeliness, then monitoring frequency is improved, but power consumption increases

Engineering Contradiction:

Improvedetection timelinessVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The transceiver is activated periodically at specific time intervals to transmit sensor data, rather than operating continuously. This periodic activation maintains timely detection capability while significantly reducing power consumption by keeping the transceiver in a low-power state between transmission events.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The transceiver dynamically switches between active and inactive states based on transmission needs. The system adjusts the transceiver's operational state, transitioning from a continuously active state to a dynamically controlled state where it activates only when data transmission is required, optimizing the balance between detection timeliness and power consumption.

Inventive Principle:

Principle #15Dynamics

2Loss of information

If frequent data transmission is implemented to improve monitoring continuity, then data availability is improved, but communication overhead increases

Engineering Contradiction:

Improvedata availabilityVSAvoidcommunication overhead

Core Design Contradiction:

Loss of informationVSLoss of time

Solution Approach 1:

The system transmits data selectively rather than continuously, sending only the necessary portions of data at optimized intervals. This partial action approach ensures adequate data availability for monitoring while reducing unnecessary communication overhead and associated time losses.

Inventive Principle:

Principle #16Partial or excessive action

3Reliability

If secure authentication is implemented to improve data security, then security is improved, but communication complexity increases

Engineering Contradiction:

Improvedata securityVSAvoidcommunication complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

Authentication credentials and security parameters are pre-configured and established before actual data transmission begins. This preliminary setup of secure communication channels ensures data security is maintained while reducing the complexity of real-time authentication processes during ongoing communications.

Inventive Principle:
