Solution Overview

Problem

Medicament delivery devices often require sensors to be switched off during storage and then turned on before use, but existing solutions are inadequate for ensuring this functionality.

Innovation Solution

A label assembly with a first and second label section, where the second label section is releasably connected to the first, featuring a switch mechanism that activates the processor only when the sections are separated, using various switch configurations such as magnetic reed switches, photo-detectors, or temperature sensors to ensure the processor is activated just before use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If sensors are kept on during storage period, then sensor readings are immediately available when needed, but power is consumed unnecessarily during storage

Engineering Contradiction:
Improvesensor readinessVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The label assembly is prepared in advance with the processor deactivated during storage. The switch mechanism is pre-configured so that when the cap is removed, the switch automatically activates the processor, ensuring immediate sensor readiness without continuous power consumption during storage period

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The device automatically activates the processor through the switch mechanism when the cap is removed, without requiring manual intervention. The system self-regulates power consumption by keeping the processor deactivated during storage and automatically activating it when needed

Inventive Principle:
Principle #25Self-service

2Use of energy by moving object

If sensors are switched off during storage, then power consumption is minimized, but sensors may not be activated at the right time before use

Engineering Contradiction:
Improvepower consumptionVSAvoidsensor activation timing
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The switch mechanism is pre-configured on the label assembly to detect cap removal and automatically activate the processor at the precise moment when the device is ready for use, ensuring correct activation timing without continuous power consumption

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The switch mechanism provides feedback about the cap position (attached or removed) to the processor, enabling the system to automatically determine when activation is appropriate and ensuring sensors are activated at the correct time based on real-time status

Inventive Principle:
Principle #23Feedback

3Use of energy by moving object

If a switch mechanism is added to control processor activation, then power consumption during storage is reduced, but device complexity increases

Engineering Contradiction:
Improvepower consumptionVSAvoidswitch mechanism
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The switch mechanism is integrated into the label assembly itself, merging the switching function with the existing label structure. This combines multiple functions (labeling, switching, and processor control) into a single integrated component, minimizing additional complexity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The label assembly serves multiple functions: it provides device identification information and simultaneously houses the switch mechanism for processor control. This multi-functional design reduces the need for separate components, thereby limiting the increase in device complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Ensures that the processor and associated sensors are activated only when the device is ready for use, preventing unnecessary power consumption during storage and ensuring accurate sensor readings at the right time.

Implementation Method 1

The switch part of the first label section comprises a magnetic reed switch. The counter switch part of the second label section comprises a magnet.

Methodology Applied
Scientific EffectMagnetic reed switch: Magnetic Field

Implementation Method 2

The switch part of the first label section comprises a photo-detector arranged under the transparent portion of the first label section. The photo-detector of the switch part is electrically connected to the processor and is configured to activate the processor when light is detected.

AI summary

The present disclosure provides a label assembly of a medicament delivery device, the label assembly comprising a first label section, a second label section, and a switch. The second label section is releasably connected to the first label section. The switch is formed by a switch part on the first label section and a counter switch part on the second label section. The switch part is connected to the counter switch part when the second label section is connected to the first label section, and the switch part is disconnected to the counter switch part when the second label section are spaced apart from the first label section.
