Solution Overview

Problem

Conventional sensor housing containers are inconvenient for elderly or visually impaired users, as they struggle to extract and properly mount sensors due to the sensors' thinness and exposed electrodes, leading to potential damage during insertion.

Innovation Solution

A container design featuring a pull-out sensor case with a guide protrusion and push-out protrusion, allowing for easy alignment and mounting of sensors into a measurement device without exposing electrodes, ensuring safe and secure insertion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If sensors are housed in a cylindrical container in no order, then multiple sensors can be stored in a compact space, but elderly or visually impaired users cannot easily take out a single sensor

Engineering Contradiction:

Improvenumber of sensors storedVSAvoidease of extracting a single sensor

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

The container is divided into multiple storage chambers, each capable of holding a single sensor. This segmentation allows users to easily identify and access one sensor at a time without having to search through a jumbled collection, while still maintaining compact storage capacity for multiple sensors.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If sensors are discharged with exposed electrodes, then the sensor can be removed from the container, but the thin sensor with exposed electrodes is difficult to connect properly and may bend or be damaged

Engineering Contradiction:

Improveease of removing sensor from containerVSAvoidrisk of sensor damage during insertion

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

A protective sheath or guide structure is introduced as an intermediary element between the sensor and the insertion port. This intermediary protects the thin sensor body and exposed electrodes during the transfer process, preventing bending or damage while still allowing the sensor to be removed from the container and inserted into the measurement device.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The sensor is pre-positioned or pre-oriented within the storage chamber or discharge mechanism so that when it is removed, it is already in the correct orientation and position for insertion. This preliminary action eliminates the need for manual manipulation that could cause damage to the thin sensor.

Inventive Principle:

Principle #10Preliminary action

AI summary

A sensor housing container comprises a container having an opening, a lid that covers the opening, and a sensor housing body that can be pulled out of the opening of the container. The sensor housing body includes a sensor case, a plurality of sensors, and a spring that biases these sensors. The sensor case is provided with a sensor discharge port at the portion where the sensors are biased by the spring. Also, this sensor discharge port is provided with a guide protrusion for aligning the sensor discharge port with a sensor insertion port of a measurement device. Furthermore, the inner face of the container is provided with a push-out protrusion that contacts with the end of the sensors on the opposite side from electrodes, at the portion corresponding to the end of the sensors on the opposite side from the electrodes inside the sensor case.
