Beverage Cap Perforation Mechanism for Additive Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage bottle designs that separate water and additives by storing the additive in powder form in the cap face difficulties due to the resistance of compressed additives, which can prevent the arm and cutting member from pivoting and perforating the foil, making it hard to release the additive effectively.
Innovation Solution
A device with a basic structure and a releasable closing element, featuring an axially displaceable holder partially filled with additives, where a lower perforation structure under the holder allows easy perforation and release of the additive under gravitational force, facilitated by a pivot arm mechanism that ensures controlled and reliable perforation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If the additive is compressed in powder form in the holder, then the storage stability and shelf-life of the beverage is improved, but the resistance of the additive increases, preventing the arm and cutting member from pivoting and perforating the foil
Solution Approach 1:
Instead of having the cutting member pierce through compressed powder from above, the invention inverts the approach by having the holder itself be perforated from below. The foil closing the holder is pierced by the perforation structure, causing the holder to collapse and release powder through gravity, eliminating the need to pierce through compressed material.
Solution Approach 2:
The invention extracts the cutting member from the system and replaces it with a perforation structure that acts on the foil rather than the powder. The cutting function is separated from the powder interaction, applying force only to the foil to initiate holder collapse and powder release.
2Duration of action of stationary object
If the additive is stored in the cap to separate it from water, then the shelf-life is improved and transport costs are reduced, but the mechanism to release the additive becomes complex and unreliable
Solution Approach 1:
The holder is pre-formed with a foil closure that is designed to be perforated. The perforation structure is pre-positioned to engage the foil at the correct location, ensuring reliable and consistent release without requiring complex mechanisms during operation.
Solution Approach 2:
The system uses gravity as a self-service mechanism to release the powder. Once the foil is perforated, the holder automatically collapses and powder flows out through gravity without requiring additional actuation or complex release mechanisms.
3Ease of operation
If an arm with a cutting member is used to pierce the foil, then the additive can be released, but the mechanism is complex and may fail due to resistance from compressed powder
Solution Approach 1:
The arm and cutting member mechanism is completely removed from the system. Instead, a simple perforation structure with piercing elements directly engages the foil, eliminating the need for pivoting arms and complex mechanical linkages.
Solution Approach 2:
The complex mechanical arm-pivoting system is replaced with a simpler direct perforation mechanism. The piercing elements directly puncture the foil without requiring intermediate mechanical transformations or multiple moving parts.
