Diagnostic Pouch With Fold-Out Buffer Support for Upright Storage

Solution Overview

Problem

Conventional pouches for in-vitro diagnostic items require a separate manufacturing step for a buffer supporter, which increases the size of the storage space needed, making them less efficient for storing multiple items.

Innovation Solution

The pouch integrates a buffer supporter formation portion that extends from the pocket portion, allowing the buffer supporter to be formed by bending motion without additional manufacturing steps, with marked bending lines and grooves for precise folding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a separate buffer supporter is manufactured and stored in the pouch, then the buffer can be supported in an upright state, but the storage space size increases and manufacturing complexity increases

Engineering Contradiction:

Improvebuffer support stabilityVSAvoidstorage space size

Core Design Contradiction:

ReliabilityVSVolume of stationary object

Solution Approach 1:

The buffer supporter function is merged with the pouch structure itself. The pouch includes a buffer support formation portion that can be bent to form a supporter, eliminating the need for a separate buffer supporter component. This integration reduces the overall storage space required while maintaining the buffer support function.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The buffer support formation portion is designed to be dynamically transformable. It can be bent along predetermined bending lines to transition from a flat state (during storage) to an upright supporter state (during use). This dynamic transformation allows the pouch to adapt its structure based on operational needs without requiring additional components.

Inventive Principle:

Principle #15Dynamics

AI summary

A pouch for a diagnosis item includes (i) a pocket portion with a storage space configured to hold a buffer that has an elongate shape and is configured to hold a sample diluent, and (ii) a buffer supporter formation portion that is connected to one side of the pocket portion. The buffer supporter formation portion includes a buffer support hole that is sized to receive the buffer and support the buffer such that the buffer is oriented in an upright state to avoid spilling of the sample diluent. The buffer supporter formation portion includes a shelf supported by leg portions. The shelf includes the buffer support hole. The buffer supporter formation portion is configured to allow bending of the buffer supporter formation portion into a U shape, and to hold the U shape after being detached from the pocket portion.
