Glass Ampoule Breaking Bevel and Contact Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for breaking off the head of a glass ampoule are complex and costly to produce, necessitating a simpler and more economical solution.
Innovation Solution
A device with a bevel that projects obliquely to the ampoule axis, featuring contact surfaces on either side of the ampoule to absorb forces and break off the head at a predetermined point, with optional spring elements and varying designs such as cradles or cylindrical forms with bevels and contact surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a separate movable slope body is used to break off the ampoule head, then the breaking function is achieved, but the device complexity increases and production cost rises
Solution Approach 1:
The patent merges the slope (bevel A) directly into the ampoule receptacle body, eliminating the need for a separate movable slope body. The bevel is formed as an integrated component of the receptacle, which simplifies the overall device structure and reduces production costs while maintaining the head-breaking function.
Solution Approach 2:
The ampoule receptacle serves multiple functions: it holds the ampoule, provides the breaking bevel, and includes contact surfaces for force absorption. This multi-functional design eliminates the need for separate components, reducing device complexity and manufacturing cost.
2Reliability
If contact surfaces are added to absorb breaking forces, then the reliability of the device improves, but the device complexity increases
Solution Approach 1:
The contact surfaces B and C are integrated into the ampoule receptacle body rather than being separate components. This integration allows the receptacle to absorb breaking forces directly, improving reliability without adding device complexity.
Solution Approach 2:
The ampoule receptacle simultaneously provides holding, breaking (via bevel A), and force absorption (via contact surfaces B and C) functions. This multi-functionality ensures reliable operation while maintaining simple device construction.

AI summary
An apparatus for breaking off the head of a glass ampoule that is composed of a cylindrical body, a neck forming a predetermined breaking point and a head, comprising an incline A extending in an inclined manner to the axis of the ampoule to be inserted toward the same, wherein a first support surface (C) is disposed on the side of the incline (A) causing a break-off of the head in the region above the bottom of the ampoule to be inserted at a radius of the ampoule from the axis of the apparatus and a second support surface (B) is disposed on the opposite side beneath the neck of the ampoule (inserted in the apparatus) at a distance from the axis of the apparatus that corresponds to the radius of the ampoule, wherein during a relative movement of the apparatus to the ampoule in the direction of the axis thereof the incline (A) breaks off the head at the neck.
