Solution Overview

Problem

Hand-held analysis devices for diabetics require improvements in user comfort and measurement efficiency, as users must manually prepare the device for measurements, which can be cumbersome and wasteful of consumables if not used immediately.

Innovation Solution

A hand-held analysis device with a mechanical assembly that can be activated only when needed, featuring a lancing drive and consumable supply system, allowing for automatic deactivation and sterility preservation, and a dual active state for measurement preparation and result display without mechanical assembly engagement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the mechanical assembly is activated to prepare for measurement, then the measurement can be performed, but the consumable elements (test strips, lancets) lose sterility and cannot be stored for later use

Engineering Contradiction:
Improvemeasurement preparationVSAvoidconsumable sterility
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The device transitions between different operational states (first active state for measurement preparation, second active state for viewing results) allowing the mechanical assembly to be dynamically activated only when needed, preserving consumable sterility during storage and inactive periods

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The device uses periodic activation of the mechanical assembly rather than continuous operation, activating it only during measurement preparation and keeping it inactive during result viewing or storage, thereby maintaining consumable element sterility

Inventive Principle:
Principle #19Periodic action

2Productivity

If the device remains in measurement preparation state, then quick measurements can be performed, but energy is continuously consumed and consumables are wasted if not used

Engineering Contradiction:
Improvemeasurement speedVSAvoiddevice energy consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The device alternates between active measurement preparation state and inactive state, consuming energy only periodically when measurements are actually performed rather than continuously, thereby reducing overall energy consumption while maintaining measurement readiness

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The mechanical assembly and display device dynamically transition between active and inactive states based on user interaction, activating components only when needed for measurement or result viewing, optimizing energy usage according to actual operational requirements

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If the device allows viewing previous results without measurement preparation, then user convenience is improved, but the device structure becomes more complex

Engineering Contradiction:
Improveresult viewing convenienceVSAvoiddevice structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The device uses different operational states (first active state for measurement, second active state for result viewing) to provide multiple functions without requiring separate physical structures, achieving versatility through dynamic state transitions rather than structural complexity

Inventive Principle:
Principle #15Dynamics

AI summary

The invention relates to a handheld analysis device having a mechanical assembly comprising a transport arrangement (9) for analytical consumable elements (4, 5), a display arrangement (7), a sensor (6) for inspecting a bodily fluid sample obtained by a lancet prick, a memory for saving a series of measurement results, a first activation element (13), wherein the activation thereof sets the device (1) to a first active state, activating the mechanical assembly and preparing a measurement, wherein a measurement is started by activating one of the activation elements (13, 15, 16, 17) and a second activation element (15), wherein the activation thereof sets the device (1) to a second active state. The device according to the invention is characterized in that by activating the second activation element (15), the display device (7) is switched on without activating the mechanical assembly.
