Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for measuring and mixing additives with fluids, such as baby formula milk powder, are cumbersome and inaccurate, leading to potential deterioration due to exposure to air and improper wetting before use.
Innovation Solution
A multiple dosing device with a magazine system that includes moveable tubes for additives, controlled by push buttons, ensuring precise dosing and protection from moisture until use, compatible with various additives and adaptable for different brewing devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If additive is stored in a can and measured by hand, then the device complexity is low, but the measurement precision is poor and the additive deteriorates due to air exposure
Solution Approach 1:
The additive container is divided into multiple separate tubes, each containing a pre-measured dose of additive. This segmentation allows for precise dosing without complex measurement mechanisms, as each tube represents a ready-to-use portion with accurate quantity control.
Solution Approach 2:
The additive is pre-measured and pre-packaged into individual tubes before use. This preliminary action eliminates the need for complex dosing mechanisms during operation, as the precise measurement is already completed during manufacturing, thereby improving dosing accuracy without increasing device complexity.
2Reliability
If additive is stored in a can and exposed to air, then the device complexity is low, but the additive deteriorates due to moisture and air exposure
Solution Approach 1:
The additive is divided into multiple sealed tubes, each hermetically sealed to prevent contact with air and moisture. This segmentation provides reliable protection against deterioration while maintaining relatively simple device structure, as the sealing function is built into the tube design rather than requiring complex protective systems.
Solution Approach 2:
Each tube provides an inert, sealed environment for the additive, isolating it from harmful air and moisture exposure. This creates a protective atmosphere around each dose without requiring the entire device to be complex, as the inert environment is achieved through simple tube sealing.
3Measurement precision
If multiple types of magazines are used for different additives, then the measurement precision can be optimized for each additive, but the ease of manufacture and handling decreases
Solution Approach 1:
The magazine is designed with a universal structure that can accommodate tubes of different additives through a standardized tube holder and through-opening system. This universality allows the same magazine design to handle various additives with consistent precision, eliminating the need to manufacture multiple specialized magazine types for different additives.
4Ease of operation
If tubes are fixed in the magazine, then the device complexity is low, but the ease of operation decreases when tube activation is needed
Solution Approach 1:
The tubes are designed to be movable within the magazine rather than fixed, allowing them to be easily pushed or pulled out as needed. This dynamic arrangement enables simple tube activation and replacement operations without requiring complex locking or release mechanisms, maintaining low device complexity while improving ease of operation.

AI summary
The present invention concerns a multiple dosing device and magazine for releasing one or more doses of additive. The multiple dosing device comprises a magazine (1) having a number of through openings (10),each receiving a tube (2), containing a dose of additive. The through openings (10) and tubes (2) extended axially between two opposite ends of the magazine (1).The tubes (2) are arranged moveable in an axial direction inside respective through opening (10).Each tube (2) has a pointed lower end (14).An upper foil (3) and a lower foil (4) are placed adhered to the opposite ends of the magazine (1).The ends of the tubes (2) are placed abutting or adjacent the upper and lower foils (3, 4), respectively. The multiple dosing device further comprises an activation part (5, 24) with push buttons (6, 26), which push buttons (6, 26) are placed for controlling the axial position of one tube (2) each.
