Cap Construction Foil Cutting and Collection Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cap constructions for containers fail to efficiently remove additives, such as vitamins or drugs, from storage spaces without leaving residue or obstruction, posing safety risks and usability issues due to loose foil fragments.
Innovation Solution
A cap construction featuring a screw cap with a cutting element and support structure that curls and collects the cut foil, ensuring complete removal of additives and preventing loose foil from entering the container, utilizing a mutual screw-thread coupling and a stop means with a recess to contain the cut foil.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cutting element is used to cut the foil sealing the storage space, then the additive can be dispensed into the container, but the cut foil may become detached and enter the user's mouth or obstruct the opening
Solution Approach 1:
The harmful element (cut foil) is extracted from the dispensing path by directing it into a separate collection space (recess) within the cap construction, preventing it from entering the container or obstructing the opening
Solution Approach 2:
The recess acts as an intermediary space that captures and holds the cut foil, serving as a buffer between the cutting element and the container opening to prevent foil from reaching the user
2Productivity
If the foil is cut for opening the storage space, then the additive can flow into the container, but the foil removal is untidy and additives remain in the storage space
Solution Approach 1:
The recess is pre-positioned to guide and collect the foil as it is being cut, ensuring that the cutting action automatically directs foil into the collection space rather than allowing it to scatter or remain obstructive
Solution Approach 2:
The foil transitions from a static sealing barrier to a dynamic element that is actively directed into the recess during the cutting process, enabling complete opening of the storage space while capturing the foil
3Object-affected harmful factors
If a stop means with recess is added to collect the foil, then foil safety is improved, but the device complexity increases
Solution Approach 1:
The recess is integrated into the existing cap construction structure, serving dual functions as both a structural component and a foil collection mechanism, thereby minimizing additional complexity
Solution Approach 2:
The recess is nested within the existing cap geometry, utilizing the available internal space of the cap construction to house the foil collection function without adding external complexity
