Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing capsules for mixing dry or liquid ingredients with liquids in bottles face issues such as mechanical failure, leakage, contamination, and inconvenience due to complex designs and fragile membranes, which lead to inefficiencies and safety hazards.
Innovation Solution
A dispensing capsule comprising a cup and base jointed during manufacturing, with a diaphragm button and stake mechanism that applies concentrated stress to rupture a conically shaped base plate, allowing controlled release of ingredients into a bottle without leakage or spillage, featuring a durable and hermetic seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a frangible membrane is used to seal the dispensing capsule, then the capsule can be ruptured to dispense contents, but the membrane is fragile and subject to mechanical failure under pressure or temperature changes
Solution Approach 1:
The patent changes the material parameters and structural properties of the sealing mechanism from a thin frangible membrane to a thicker base plate with integrated tear lines. This structural parameter change enhances reliability while maintaining dispensing functionality.
Solution Approach 2:
The sealing structure combines multiple functional elements into a composite base plate assembly including the base plate itself, integrated tear lines, and stake mechanism. This composite structure provides both durability and controlled rupture capability.
2Ease of operation
If a separate plunger welded to a diaphragm button is used, then the dispensing mechanism can be actuated, but the weld may be defective causing the plunger to detach and create a choking hazard
Solution Approach 1:
The patent merges the plunger function directly into the stake structure. The stake is formed as an integral part of the base plate assembly with the diaphragm button, eliminating the separate welded components. This integration ensures that no loose parts can detach and eliminates the welding defect risk.
Solution Approach 2:
The entire base plate assembly including the stake is designed as a single-use component that is discarded after dispensing. This disposable approach eliminates the need for durable welded joints while ensuring safety, as the entire mechanism is replaced rather than repaired.
3Ease of manufacture
If multiple separate components are used to manufacture the dispensing capsule, then assembly is possible, but the seal is less reliable and more expensive to manufacture
Solution Approach 1:
The patent combines multiple sealing functions into a single integrated base plate assembly that includes the base plate, tear lines, and stake mechanism. This reduction in component count simplifies assembly while enhancing seal reliability through integrated design.
Solution Approach 2:
While reducing overall component count, the base plate itself is segmented with integrated tear lines that create controlled separation zones. This segmentation allows the plate to rupture in a predictable pattern while maintaining structural integrity during normal use.
4Ease of operation
If a frangible membrane is used, then the capsule can be ruptured to mix ingredients, but capillary action may leak contents into the liquid before use
Solution Approach 1:
The patent changes the physical parameters of the sealing structure by using a thicker base plate with controlled tear lines instead of a thin frangible membrane. This parameter change eliminates capillary action leakage while preserving the ability to rupture for mixing.

AI summary
A dispensing capsule has a diaphragm button, stake and frangible membrane for a system for selectively dispersing the contents of a cup into an attached bottle. A frangible membraned cup has a diaphragm button operably attached to a stake with the stake's sharp point at one end and the diaphragm button on the opposing end. A cavity is disposed in the cup for consumable product defined by side walls and a base plate. Preloaded ingredients contained within the hermetically sealed cup are discharged from the dispensing capsule into a bottle by simply depressing a button disposed on the diaphragm of the cup, thereby actuating the stake to thrust forward and apply concentrated pressure abaxially to the frangible membrane. This concentrated pressure pierces substantially the center of the frangible membrane, causing it to rupture and progressively opening it. The diaphragm button locks in this downward position, holding the stake into the opened frangible membrane to maintain the opening, permitting the contents to flow through the frangible membrane and exit the cavity of the cup.
