Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing specimen measurement devices for self-monitoring blood glucose, particularly for diabetes patients, often have error displays that are overlooked due to their simplicity and small size, leading to potential waste of sensor pieces and physical stress from lost blood, and require cumbersome cable connections for data transmission.
Innovation Solution
A specimen measurement device with a measurement unit, a decision unit for assessing measurement conditions such as temperature, charge, and time, and a wireless data transmitter, which automatically determines suitability and alerts the user through a communication apparatus, ensuring measurements are conducted under appropriate conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple display screen with small symbols is used to reduce device complexity and cost, then device complexity is reduced, but the error display becomes unremarkable and is easily overlooked by users
Solution Approach 1:
The patent introduces a communication apparatus (such as a smartphone or PC) as an intermediary to receive and display measurement condition data wirelessly. This mediator handles the complex display tasks, allowing the specimen measurement device to maintain a simple structure while ensuring error alerts are prominently displayed on the communication apparatus's larger screen.
2Loss of information
If cable connection is used for data transmission between specimen measurement device and personal computer, then data can be transmitted and stored, but user burden increases due to cumbersome connection requirements
Solution Approach 1:
The patent replaces the mechanical cable connection system with a wireless communication system. The data transmitter in the specimen measurement device wirelessly transmits measurement condition data to the communication apparatus, eliminating the need for physical cable connections and significantly improving ease of operation for users.
3Productivity
If measurement is performed without checking measurement conditions, then measurement process is simplified and faster, but measurement accuracy and reliability are compromised
Solution Approach 1:
The patent implements preliminary action by having the measurement condition decision unit evaluate measurement conditions (temperature, charge amount, time-counting status) before the actual measurement is performed. This pre-check ensures that measurements are only conducted when conditions are suitable, maintaining reliability without significantly impacting measurement speed.
Solution Approach 2:
The system employs feedback by transmitting measurement condition data to the communication apparatus, which provides visual feedback to the user about whether measurement conditions are appropriate. This feedback loop ensures users are informed of measurement suitability while maintaining a streamlined measurement process.

AI summary
A specimen measurement system simplifies the function of a measurement device and facilitates measurement under an appropriate condition. Use is made of a specimen measurement device suitable for the system. The specimen measurement device includes a measurement unit, a measurement condition decision unit, and a communication unit. The measurement unit measures a specific component contained in the specimen. The measurement condition decision unit decides suitability of measurement conditions necessary for the measurement, and generates measurement condition data including decision result about the suitability of the measurement conditions. The communication unit transmits the measurement condition data through wireless communication.
