Measurement Device With Movable Portion for Sensor Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Downsized measurement devices are difficult to hold and insert sensors due to their compact size.
Innovation Solution
A measurement device with a movable portion that can be shifted between a storage position and an extension position, increasing the device's area for easier handling and providing an insertion guide and ejection mechanism for the sensor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the measurement device is downsized, then portability is improved, but ease of holding and sensor insertion deteriorates
Solution Approach 1:
The measurement device incorporates a movable portion that can shift between a storage position and an extension position. When extended, it increases the device's area to provide better grip and facilitate sensor insertion. This dynamic transformation allows the device to adapt its physical characteristics during operation, resolving the contradiction between compact size and ease of handling.
Solution Approach 2:
The movable portion extends in a direction along the sheet surface of the inserted sensor, effectively utilizing the longitudinal dimension of the device. By expanding along this dimension, the device increases its effective area for handling without significantly increasing its overall volume, thus maintaining portability while improving ease of operation.
2Ease of operation
If the movable portion is extended to improve handling, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The movable portion is integrated as part of the main body structure, merging the expansion mechanism with the overall device design. This integration reduces the need for separate components and simplifies the structural complexity, while still providing the benefit of extended handling area when needed.
Solution Approach 2:
The movable portion can be manually extended and retracted by the user without requiring additional actuators or complex control systems. This self-service mechanism allows the device to change its configuration on-demand, reducing mechanical complexity while maintaining operational ease.
3Object-affected harmful factors
If the movable portion covers the insertion guide at storage position, then foreign matter entry is prevented, but ease of sensor insertion requires additional action
Solution Approach 1:
The movable portion is designed to automatically or easily extend before sensor insertion, preliminarily exposing the insertion guide portion. This preliminary action ensures the insertion path is clear and accessible, preventing foreign matter entry while facilitating smooth sensor insertion without requiring additional steps during the actual insertion process.

AI summary
Provided is a measurement device that measures a specimen using a sheet-shaped sensor. The measurement device includes: a main body portion in which an insertion port into which the sensor is inserted is formed and a measurement unit that executes measurement related to the specimen is provided; and a movable portion that is movable with respect to the main body portion in a direction along a sheet surface of the sensor in a state of being inserted into the insertion port, and is movable between a storage position and an extension position where an area of the main body portion in planar view is increased more than an area when the movable portion is disposed at the storage position.
