Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing supplemental nursing systems are not widely used due to a steep learning curve, daily replacement needs, formula leakage, and high financial and waste costs, and they do not provide a leakproof solution for breastfeeding challenges such as low milk supply, baby latching issues, and bonding difficulties.

Innovation Solution

A leakproof supplemental nursing system featuring a silicone squeeze pouch with an airtight seal and a connecting silicone tube with a flow controller, including a BPA-free lid, adjustable flow rate, and a leak-proof design, allowing easy setup and use without the need for lactation consultants.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional plastic supplemental nursing systems are used, then the system can be manufactured simply and at low cost, but the system requires daily replacement and causes formula leakage

Engineering Contradiction:

Improveleakproof performanceVSAvoidsystem structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses silicone material for both the pouch and tube components, creating a composite system that combines flexibility, durability, and leakproof performance. The silicone material allows the system to be reused multiple times unlike traditional plastic systems, while maintaining simplicity in design and assembly.

Inventive Principle:

Principle #40Composite materials

2Ease of operation

If traditional supplemental nursing systems are used, then the basic function of milk transfer is achieved, but the system requires lactation consultant training and has a steep learning curve

Engineering Contradiction:

Improveease of setupVSAvoidsystem configuration

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system incorporates a flow controller that automatically regulates milk flow without requiring user intervention or training. The squeeze pouch design allows mothers to easily control milk delivery by simply squeezing the pouch, eliminating the need for lactation consultant training while maintaining safe and effective milk transfer.

Inventive Principle:

Principle #25Self-service

3Loss of substance

If traditional plastic supplemental nursing systems are used, then the system can be produced with simple manufacturing processes, but formula leakage causes waste and additional financial cost

Engineering Contradiction:

Improveformula wasteVSAvoidmanufacturing process

Core Design Contradiction:

Loss of substanceVSEase of manufacture

Solution Approach 1:

While the silicone components are reusable, the system incorporates disposable elements such as the nipple cover and tube that can be easily replaced. This hybrid approach prevents formula leakage and waste while keeping the overall system cost-effective and simple to manufacture, as only small components need to be disposable rather than the entire system.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

AI summary

Disclosed in the present invention is a leakproof supplemental nursing system, comprising a silicone squeeze pouch with an airtight seal and connecting a silicone tube with a flow controller. The system further comprises a leakproof BPA-free lid instead of the artificial nipple that is normally used including an attached airtight tube inserted that can be changed out every 24-48 hours for safety. It also has a silicone BPA-free milk storage pouch that is used for easy suction and cleaning. This pouch includes a handle for hanging on taller surfaces for easy gravitation. It has a thin tube that is easy to clean and has a flow control attachment that can adjust the supplemental milk from a drip flow to a medium or a faster flow.
