Solution Overview

Problem

Existing transportation methods for medical equipment, such as endoscopes, often result in contamination due to gaps between the transport bag or box and the equipment tray, which can compromise the cleanliness and safety of the equipment during transport.

Innovation Solution

A transport bag and box design featuring a bag body with a folding mechanism and connecting edges that securely enclose a tray, minimizing gaps and preventing contamination, along with a transport box that uses a cover plate to seal the accommodating space and prevent external dust or impurities from entering.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional transport bag with two closed edges is used to cover the tray, then the structure is simple and easy to manufacture, but gaps between the bag and tray occur causing contamination

Engineering Contradiction:
Improvecontamination preventionVSAvoidbag structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The transport bag is divided into multiple parts (first part and second part) that are folded and connected along folding sides. The first part includes multiple first connecting sides and the second part includes multiple second connecting sides, creating a segmented structure that can adapt to the tray dimensions and eliminate gaps, thereby preventing contamination while maintaining reasonable structural complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The transport bag is designed to completely enclose the tray with its multiple connecting edges forming a nested configuration around the tray perimeter. The bag body with accommodating cavity nests the tray inside, creating a gap-free enclosure that prevents contamination while maintaining structural integrity

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of manufacture

If gaps exist between the transport bag and tray, then the bag structure remains simple, but contamination risk increases

Engineering Contradiction:
Improvebag manufacturing simplicityVSAvoidcontamination risk
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The transport bag incorporates folding sides that allow dynamic adjustment of the bag structure to match different tray dimensions. The folding mechanism enables the bag to adapt its shape and size to completely enclose the tray without gaps, preventing contamination while maintaining ease of manufacture through flexible material usage

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The transport bag is constructed as a flexible shell that can be folded and shaped to conform to the tray contours. The flexible material allows the bag to create a tight, gap-free enclosure around the tray, eliminating contamination pathways while remaining simple to manufacture from flexible plastic or similar materials

Inventive Principle:
Principle #30Flexible shells and thin films

AI summary

The embodiment of the present application relates to the technical field of transportation tools for medical equipment, and particularly discloses a transport bag and a transport box. The transport bag includes a bag body, which is provided with an accommodating cavity and a bag opening communicated with the accommodating cavity. The bag body includes a first and a second part connected with each other. A first folding side is provided between the first and second parts. The first and second parts are folded and connected with each other along the first folding side. The bag opening is located on the first part. The first part includes several first connecting sides. The second part includes several second connecting sides, and one of the second connecting sides is correspondingly connected with one of the first connecting sides so that the bag body forms a plurality of connecting edges.
