Bottle With Membrane-Sealed Receptacle for On-Demand Formula Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing baby formula bottles require pre-mixing and temperature maintenance when traveling, making it inconvenient to mix water with formula on demand in a sterile environment.
Innovation Solution
A bottle design featuring a membrane-sealed receptacle that releases contents into the bottle body upon membrane separation, allowing for easy mixing of formula powder with water, with flexible arms retaining the receptacle during membrane removal and aiding in mixing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If formula is mixed before leaving when traveling, then the bottle is ready for feeding, but temperature maintenance is required and it cannot be prepared on demand
Solution Approach 1:
The formula powder is pre-measured and sealed in the receptacle before travel, and the bottle is pre-sterilized. When needed, only the membrane needs to be removed and water added, eliminating the time-consuming processes of measuring, mixing, and temperature maintenance while enabling on-demand preparation
2Ease of operation
If formula is mixed before leaving when traveling, then the bottle is ready for feeding, but it requires keeping the bottle at appropriate temperature
Solution Approach 1:
The formula is pre-measured and sealed in the receptacle, and the bottle is pre-sterilized. When feeding is needed, only water addition and membrane removal are required, eliminating the need for temperature maintenance equipment and procedures while enabling convenient on-demand preparation
3Adaptability or versatility
If a membrane-sealed receptacle system is used, then on-demand mixing is enabled, but the device structure becomes more complex
Solution Approach 1:
The bottle is divided into functional segments: the body for water storage, the receptacle for pre-measured formula powder, and the membrane as a seal. This segmentation allows each component to perform its specific function efficiently, enabling on-demand mixing while keeping the overall structure manageable through modular design
4Reliability
If the receptacle is retained by flexible arms, then the receptacle stays in position during membrane removal, but the device complexity increases
Solution Approach 1:
The retaining arms are designed as flexible resilient members that can dynamically adjust their position. During membrane removal, the arms expand to engage under the shoulder and retain the receptacle. After formula release, the arms can compress to allow the receptacle to be removed or remain in position, providing adaptive retention without complex mechanical structures
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
Enables convenient and sterile mixing of baby formula on demand by releasing the receptacle's contents into the bottle, ensuring a pre-measured amount of formula is mixed with water efficiently, improving travel convenience.
Implementation Method 1
each of the arms comprises a flexible resilient member moveable to a compressed position in which the arm is located adjacent a side wall of the receptacle and the receptacle can be received inside of the neck, and wherein upon release of force from the arm, the arm moves to an expanded position in which the arm engages under the shoulder

AI summary
A bottle comprises a body having an opening in an upper end for receiving fluid; a membrane provided to seal across the opening; and a receptacle sealingly secured to a surface of the membrane within the body. Separation of the membrane from the opening in the receptacle releases the receptacle such that the contents of the receptacle are released into the body.
