Solution Overview

Problem

Medical devices, such as infusion pumps and sensors, face challenges in energy-efficient data transmission due to the need for continuous power consumption during data communication, which is not optimized for low energy usage.

Innovation Solution

A medical device system that activates data transmission only when necessary, using an activation switch connected to a transceiver unit, which can be activated by an external signal, ensuring communication occurs only when the transmitter and receiver are in close proximity, reducing energy requirements by limiting data transmission distance and power usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If data transmission is performed continuously or with long activation periods, then data communication reliability is improved, but energy consumption increases

Engineering Contradiction:
Improvedata communication reliabilityVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system uses periodic activation where the transceiver unit is switched on only during brief intervals when data transmission is actually needed, rather than remaining continuously active. This periodic operation mode allows the device to maintain communication reliability by activating only when necessary while dramatically reducing overall energy consumption during idle periods.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system dynamically adjusts the activation state of the transceiver unit based on communication needs. An activation switch controls whether the transceiver is in a low-power state or an active transmission state, allowing the device to adapt its energy consumption profile to actual operational requirements rather than maintaining a fixed operational mode.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If transmission distance is increased to allow remote control, then ease of operation is improved, but energy consumption and device size increase

Engineering Contradiction:
Improveremote control capabilityVSAvoidenergy consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The system is designed for local proximity operation where the external control device must be placed close to the medical device (within a short distance). This local quality approach allows the use of low-power transmission components that would not be sufficient for long-range communication, thereby maintaining ease of operation within the intended use scenario while minimizing energy consumption.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system changes the operational parameter of transmission distance to be short-range, which enables the use of lower power transmission settings. By optimizing the distance parameter rather than attempting to maximize it, the system achieves adequate ease of operation for the intended application while significantly reducing the energy requirements of the transceiver unit.

Inventive Principle:
Principle #35Parameter changes

3Use of energy by moving object

If transmission distance is decreased to reduce energy consumption, then energy efficiency is improved, but ease of operation deteriorates

Engineering Contradiction:
Improveenergy efficiencyVSAvoidease of operation
Core Design Contradiction:
Use of energy by moving objectVSEase of operation

Solution Approach 1:

The system uses partial activation where the transceiver unit is activated only for the minimum necessary duration and at the minimum necessary power level required to complete the data transmission task. This partial action approach achieves energy efficiency by avoiding excessive transmission power and duration while still maintaining adequate ease of operation for the specific intended use case of proximity-based control.

Inventive Principle:
Principle #16Partial or excessive action
