Elastic Filter Insert Collar for Secure Vessel Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter inserts for beverage preparation are laborious to insert, prone to falling out of vessels during pouring, and often require disposable materials, which can lead to damage and inefficiency in manufacturing and use.
Innovation Solution
A filter insert with a main body and a collar featuring an elastic wave-form outside contour that adapts to the vessel's opening, preventing it from falling and allowing for easy removal and universal compatibility, along with a flange for secure holding and a one-piece collar for cost-effective production and heat insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a filter insert with a rigid collar is used, then it provides stable support, but it cannot adapt to manufacturing tolerances and may damage the vessel
Solution Approach 1:
The collar is designed with a wave-form outside contour that provides flexibility, allowing it to adapt to manufacturing tolerances of the vessel opening while maintaining stable support. The flexible collar can deform to fit different opening dimensions without causing damage.
Solution Approach 2:
The collar's physical state is changed from rigid to elastic through material selection and structural design (wave-form contour). This parameter change enables the collar to dynamically adjust its shape to match the vessel opening while providing consistent support.
2Ease of manufacture
If a filter insert with a smooth collar is used, then it is easy to manufacture, but it cannot prevent the filter insert from falling out during pouring
Solution Approach 1:
The collar is designed with a wave-form outside contour featuring multiple curved ridges and grooves. This curved geometry creates friction and mechanical interlocking with the vessel opening, preventing the filter insert from falling out during pouring while remaining manufacturable.
3Area of stationary object
If the collar extends fully over the main body, then it provides complete coverage, but it becomes difficult to remove with bare hands when hot
Solution Approach 1:
The collar is segmented into distinct regions: a wave-form outside contour region for engagement with the vessel opening, and an upper region that extends over only part of the outer rim to provide heat insulation. This segmentation allows the filter insert to be gripped and removed by hand while maintaining adequate thermal protection.
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 filter insert is easily inserted and removed without damaging the vessel, prevents falling during pouring, and can be used universally, reducing manufacturing costs and ensuring safe handling even when hot.
Implementation Method 1
The collar has an elastic wave-form outside contour over a circumferential region. The outside contour serves for the flexible adaptation to an inside dimension of the insertion opening of the vessel.
Implementation Method 2
The collar being made in one piece offers the advantage of the collar being cost-effectively produced and simply installed. Moreover, handling by the user is simplified.

AI summary
A filter insert (1) for insertion into an insert opening (91) of a vessel (9) for the purpose of extracting beverages has a base body (3), which has filter openings (51), and a sleeve. A circumferential region of the sleeve has a corrugated elastic outer contour (21) which serves to flexibly match said filter insert to an internal dimension of the insert opening (91) of the vessel (9).
