Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the medical device frequently establishes communication sessions to maintain responsiveness, then user responsiveness is improved, but energy consumption increases
Solution Approach 1:
The medical device performs preliminary actions by advertising connection parameters and session status in advance, allowing external devices to prepare connection requests without requiring immediate session establishment. This enables the medical device to respond to connection requests more quickly while avoiding the need for frequent full communication session establishments, thus reducing energy consumption.
Solution Approach 2:
The patent introduces an intermediary mechanism where the medical device advertises connection information to external devices, and these external devices can establish connections based on the advertised parameters without requiring constant direct communication sessions with the medical device. This intermediary advertising mechanism reduces the frequency of direct communication sessions while maintaining responsiveness.
2Loss of information
If the medical device establishes frequent communication sessions to collect information, then information availability is improved, but device longevity decreases
Solution Approach 1:
The medical device advertises connection parameters and session status in advance, allowing external devices to collect information based on this pre-advertised information without establishing frequent communication sessions. This preliminary advertising of connection information enables information availability while preserving device battery life and longevity.
3Use of energy by moving object
If the medical device reduces communication session frequency to conserve energy, then energy consumption is reduced, but communication responsiveness deteriorates
Solution Approach 1:
The medical device performs preliminary advertising of connection parameters and session status, which enables external devices to quickly establish connections when needed without requiring frequent full communication sessions. This preliminary action maintains communication responsiveness while significantly reducing energy consumption by avoiding repeated session establishment procedures.
Data Source
AI summary
An example system includes telemetry circuitry configured for communication between a medical device and an external device associated with the medical device and processing circuitry. The processing circuitry is configured to receive, with the telemetry circuitry, an advertisement from the medical device. The advertisement includes connection parameters for a potential communication session with the medical device and an indication that the medical device is connected by an established communication session between the medical device and a connected device. The processing circuitry is further configured to identify the connected device using the indication of the advertisement, initiate a communication session between the telemetry circuitry and the connected device, and output, with the telemetry circuitry and using the communication session between the telemetry circuitry and the connected device, a request for information from the medical device.
