Dual-Layer Baby Bottle with Sealing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing baby bottles lack durability and are not suitable for frequent use, as they can warp or crack, and existing pump-to-feed systems are complex and environmentally unfriendly, with issues related to air ingestion during feeding, particularly for infants with reflux.
Innovation Solution
A baby bottle design featuring a dual-layer structure with a resilient first layer (silicone, glass, or plastic) and a second layer (plastic, silicone, or rubber) that can be co-molded, molded, or applied as a coating, providing flexibility and durability, along with a sealing mechanism to prevent air ingestion, and compatibility with breast pumps and storage systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If plastic bottles are used, then they are lightweight and easy to handle, but they can warp, crack, and become obsolete
Solution Approach 1:
The patent employs a composite material structure consisting of an inner layer (silicone, glass, or resilient plastic) and an outer layer (plastic, silicone, or thermoplastic/rubber material). This composite construction combines the lightweight advantage of plastic with the durability and crack resistance of silicone or glass, resolving the contradiction between weight and reliability.
2Reliability
If glass bottles are used, then they are durable and resistant to cracking, but they can still crack and become hazardous
Solution Approach 1:
The patent applies a protective outer layer made of resilient materials (silicone, thermoplastic, or rubber) that surrounds the inner glass or rigid plastic layer. This outer layer acts as a cushion that absorbs impact forces before they can cause cracks in the inner layer, preventing the hazardous cracking issue while maintaining durability.
Solution Approach 2:
The composite structure with an inner rigid layer (glass or plastic) and an outer resilient layer combines the durability of glass with the crack resistance and safety of flexible materials, eliminating the hazard of glass cracking while preserving durability.
3Adaptability or versatility
If conventional pump-to-feed systems are used, then they enable working moms to pump and store milk, but they include multiple parts requiring maintenance, cleaning, and storage
Solution Approach 1:
The bottle is designed with a universal interface that is compatible with multiple breast pump systems and can function both as a pumping container and a feeding bottle. The standardized opening and collar design allow it to work with various pumps while serving dual purposes, reducing the need for separate pumping and feeding equipment.
Solution Approach 2:
The patent combines the pumping chamber and feeding bottle into a single integrated unit. The bottle can be used for both pumping and feeding without requiring separate containers, thereby reducing the number of parts that need maintenance, cleaning, and storage while maintaining pump compatibility.
4Device complexity
If conventional bottles are used, then they are simple in design, but they allow air ingestion during feeding which worsens reflux symptoms
Solution Approach 1:
The patent incorporates a visual indicator (such as a colored ring or marker) that changes appearance or position to indicate the correct filling level. This allows users to easily identify the maximum fill line without complex markings, preventing overfilling that would cause air ingestion while maintaining a relatively simple bottle design.

AI summary
A cup or container assembly having a lip activated input feature. The lip activated feature permits removal of the contents from the cup or container while mitigating against leaks and/or spills. The lid includes a movable member and a baffle. The cup assembly is constructed to have streamlined assembly method due to a reduced number of parts needing separation and/or improved connecting features. The improved geometry of lid components lends to heightened ease of cleaning.
