Capsule with inward beads for cylindrical vessel protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing capsules for cylindrical vessels, particularly in the pharmaceutical and analytical sectors, fail to provide comprehensive protection against breakage when exposed to heat or during falls, as they are either heat-sensitive or only protect the upper opening area of fragile vessels.
Innovation Solution
A capsule with a cylindrical jacket surface, an upper open end, and a lower closed end, featuring a means to create a free space with inwardly directed beads or projections that prevent further insertion of the vessel, ensuring a form-fitting connection without thermal fixation, and filled with damping materials to cushion impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a capsule is pushed onto the opening of a cylindrical vessel without thermal fixation, then the application is simple and cost-effective, but the capsule only protects the upper opening area and not the entire vessel from breakage
Solution Approach 1:
The protective capsule extends from the upper opening down to the lower end of the vessel, utilizing the vertical dimension to provide comprehensive protection along the entire vessel length, not just at the opening area
Solution Approach 2:
The capsule is made of flexible plastic film material that can be pushed onto the vessel without thermal fixation, maintaining simplicity of application while providing full-length protection through the flexible nature of the material
2Reliability
If a shrink capsule is used to protect cylindrical vessels, then comprehensive protection against breakage is achieved, but heat-sensitive products cannot be protected due to heat sensitivity
Solution Approach 1:
The invention replaces the thermal fixation system (heat shrinkage) with a mechanical insertion system, where the capsule is pushed onto the vessel using manual or automated feeding devices, eliminating heat exposure for heat-sensitive products
Solution Approach 2:
The capsule material properties are designed to allow elastic deformation during insertion and then maintain form-fitting protection without requiring thermal activation, changing the activation parameter from temperature to mechanical force
3Ease of manufacture
If the capsule is made form-fitting without thermal fixation, then application is simple and cost-effective, but tolerance limits of vessel diameter must be compensated
Solution Approach 1:
The capsule material's elastic properties are utilized to accommodate diameter variations, allowing the capsule to deform elastically during insertion and then maintain a form-fitting connection despite tolerance variations in vessel diameter
Solution Approach 2:
The flexible plastic film construction allows the capsule to adapt to slight diameter variations in the vessel through elastic deformation, providing tolerance compensation without requiring precision machining or thermal processes
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The capsule effectively protects cylindrical vessels from breakage during falls by compensating for diameter tolerances and providing a cushioning effect, ensuring cost-effective and efficient protection without thermal fixation, while allowing for easy application and identification of counterfeit products.
Implementation Method 1
the free space - when the capsule is attached to the bottom end of the vessel - limited in the upper area by the bottom of the essentially cylindrical vessel. If the essentially cylindrical vessel with the capsule attached above the bottom hits the bottom with the bottom, the free space, since it padded the bottom area of the vessel, prevents breakage

AI summary
The invention relates to a capsule (1) for a substantially cylindrical vessel (2), comprising a casing surface (1a), an upper open end (1b) and a lower closed end (1c), wherein the casing surface is substantially cylindrical in the region of the open end. According to the invention, in order to protect substantially cylindrical vessels from breakage in a cost-effective manner, the casing surface has at least one means (3) above the closed end for forming a free space, which is a rib (3c) at least partially oriented inwards on the casing surface.
