Depressible Solidifying Agent Chamber in Fluid Collection Container
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid collection containers for medical suction systems have complex structures and external chambers that are costly to manufacture, prone to damage, and interfere with storage and transport, while also risking liquid escape during transport and disposal.
Innovation Solution
A fluid collection container with a closed, depressible chamber for a solidifying agent that protrudes into the container's interior, where the outer wall can be pressed inward to open the chamber, ensuring a tight seal and preventing liquid escape, featuring a one-piece design with a flexible outer wall and a transmission mechanism like a ram to facilitate the opening of the chamber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If external chambers are attached to the container for storing solidifying agents, then the solidifying agent can be introduced into the container, but the structure becomes complex and costly to manufacture
Solution Approach 1:
The chamber for the solidifying agent is integrated directly into the container wall structure, merging two previously separate components (container and chamber) into a single unified structure. This eliminates the need for separate external chambers and reduces manufacturing complexity and cost.
Solution Approach 2:
The chamber is nested within the container wall structure, with the chamber wall formed as an integral part of the container wall. The chamber protrudes into the container interior while being structurally integrated, creating a nested configuration that simplifies the overall design.
2Reliability
If external chambers are attached to the container, then the solidifying agent can be stored separately, but the chambers are prone to damage and interfere with storage and transport
Solution Approach 1:
By integrating the chamber into the container wall structure, the chamber becomes a protected internal component rather than a vulnerable external attachment. This merging eliminates the interference with storage and transport while improving damage resistance.
Solution Approach 2:
The chamber is positioned in a recessed area of the container wall, utilizing the wall thickness dimension to accommodate the chamber without increasing the external footprint of the container. This allows the chamber to be accessible while maintaining a compact form factor for storage and transport.
3Ease of operation
If the outer wall is made flexible to allow pressing, then the chamber can be opened easily, but the seal integrity may be compromised
Solution Approach 1:
The outer wall is segmented into different zones: a flexible pressing area that allows deformation for opening the chamber, and surrounding rigid sealing areas that maintain structural integrity and seal integrity. This segmentation allows localized flexibility without compromising overall seal integrity.
Solution Approach 2:
The outer wall has different mechanical properties at different locations: the pressing area is designed to be flexible and deformable, while the surrounding sealing areas maintain rigidity and structural strength. This local differentiation enables easy opening while preserving seal integrity.

Function Achieved in This Case
The solution provides a cost-effective, damage-resistant, and leak-proof mechanism for introducing a solidifying agent into the container, enhancing safety and ease of use while maintaining airtight and liquid-tight integrity during transport and storage.
Implementation Method 1
The chamber is closed on the outside of the container with an outer wall that can be pressed inwards, the chamber opening towards the interior of the fluid collection container when the outer wall is pressed in

AI summary
A fluid-collecting container for receiving a siphoned-off fluid has a closed chamber (3) for a solidifying agent (4), wherein the chamber (3) can be opened towards an internal space (5) in the fluid-collecting container under external application of force. At least part of the chamber (3) projects into the internal space (5) in the fluid-collecting container. On the outer side of the container, the chamber (3) is closed by an outer wall (31) which can be pressed inwards, wherein the chamber (3) is open towards the internal space (5) in the fluid-collecting container by the outer wall (31) being pressed in, wherein the internal space (5) continues to be closed to the outside in said region by the outer wall (31). The fluid-collecting container has a first and a second housing part (1, 2) which together form the internal space (5) in the fluid-collecting container. The outer wall (31) is formed integrally with a wall of the first housing part (1), said wall surrounding the outer wall. Said fluid-collecting container can be produced cost-effectively and prevents damage to the chamber containing the solidifying agent prior to the use thereof. Furthermore, the chamber can be opened in a simple and safe manner when required.
