Rotary Drum Ampule Opener Angular Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for opening fluid containers, such as ampules, are cumbersome, require excessive force, and pose risks of injury and contamination due to their complex designs and lack of separation from mixing and dispensing functions.
Innovation Solution
A device with a housing featuring a rotary drum and offset separating elements that allows for easy, angled rotation to separate the ampule head with minimal force, incorporating a filter and vacuum connector for safe and efficient fluid handling and mixing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a rotary device with separating elements is used to break open an ampule, then the ampule can be separated, but a great deal of force has to be applied and the device has a long projecting configuration
Solution Approach 1:
The rotary drum is arranged at an angle to the ampule axis rather than parallel, changing the dimensional relationship between the separating elements and the ampule. This angular arrangement allows the separating elements to strike the ampule head more effectively during rotation, reducing the force required for separation while maintaining a compact device configuration.
2Ease of operation
If the ampule is broken open by purely rotational force, then the ampule can be opened, but broken parts may drop into the interior and contaminate the fluid
Solution Approach 1:
The broken-off ampule head is extracted from the housing by the separating elements during the rotary motion. The housing is designed with an opening that allows the separated head to be removed from the interior space, preventing contamination of the fluid while maintaining simple rotational operation.
3Ease of manufacture
If two elements are turned relative to each other along a single rotation axis, then the ampule can be broken open, but the device complexity increases and excessive force is required
Solution Approach 1:
The rotary drum serves multiple functions: it holds the separating elements, provides the rotational motion for breaking the ampule, and its angular arrangement relative to the ampule axis optimizes the separation force. This multi-functionality reduces the need for additional components, simplifying the overall device structure while maintaining ease of manufacture.

Function Achieved in This Case
Enables safe, efficient, and hygienic handling of fluid containers with reduced force requirements, preventing contamination and injury, and allows for a space-saving design that can be used independently of mixing and dispensing devices.
Implementation Method 1
a rotary drum disposed in the second chamber rotatably about a rotation axis and having at least one separating element which, in a starting position, is offset in relation to the separable container part and, by a rotation of the rotary drum about the rotation axis, is adapted to be brought to a separating position, in which it separates the separable container part from the fluid container

AI summary
An opening device for opening a closed fluid container comprises a housing having a first chamber (1) for receiving the fluid container (3) and a second chamber (2) having an outlet (13). A part (6) of the fluid container that can be separated is arranged in the second chamber. A rotary drum (8) is rotatably supported in the second chamber. Said drum can be rotated from a starting position into a separating position in which it separates the separable container part from the fluid container. The rotational axis of the rotary drum is disposed at an angle to the connecting axis between the first and second chambers. A system for mixing at least two components uses such an opening device and a mixing container (18) having a connecting piece (19), to which the opening device is removably connected to establish a fluid connection.
