Solution Overview
Problem
Existing injector needles are inadequate for preparing drinks with milk-based ingredients, as they fail to dissolve and extract these ingredients effectively, leading to impaired flavor and wastage due to the formation of solid blocks within the capsule.
Innovation Solution
The injector needle features a hexagonal central portion with a slanted second inner channel creating a turbulent flow of pressurized hot water, along with a specific angle and diameter configuration to enhance dissolution and extraction of ingredients, and a modular design with M5 threads for secure connection to the machine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If hot water at high pressure is injected perpendicular to the capsule base, then coffee preparation is effective, but milk-based ingredients waste due to undissolved blocks
Solution Approach 1:
The water injection is segmented into multiple streams from different outlets, creating multiple contact points with the ingredients. This increases the effective surface area of water-ingredient contact, improving dissolution of milk-based ingredients and reducing wastage
Solution Approach 2:
The multi-outlet configuration creates turbulent flow and mechanical agitation within the capsule. This mechanical action helps break up solid blocks of milk-based ingredients, enhancing dissolution and preventing ingredient wastage
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
This design effectively dissolves and extracts milk-based ingredients, improving the flavor and reducing wastage by maintaining turbulent flow and increased water pressure within the capsule, ensuring efficient preparation of milk-based drinks.
