Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nursing bottles often leak, introduce air into liquids, and require orientation to prevent spills, leading to inefficient liquid consumption and complex venting structures that are difficult to clean.
Innovation Solution
A double venting system with a minimum number of components, including a vent tube and reservoir tube that seals to prevent vacuum formation and spills, allowing for easy assembly and cleaning, and incorporating color-changing components for visual appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional venting structure is used in a nursing bottle, then liquid can be consumed from the bottle, but vacuum formation occurs inside the bottle causing sucking difficulty for the infant
Solution Approach 1:
The venting function is divided into two separate tubes: a first vent tube that extends into the liquid to allow air intake during consumption, and a second vent tube that prevents vacuum formation by providing an alternative air path. This segmentation allows each tube to perform its specific function independently, resolving the contradiction between ease of consumption and vacuum prevention.
Solution Approach 2:
A valve mechanism acts as an intermediary between the two vent tubes and the bottle interior. The valve selectively opens and closes pathways based on liquid level and pressure conditions, mediating the flow of air to prevent vacuum formation while allowing liquid consumption. This intermediary control resolves the contradiction by dynamically managing the venting process.
2Reliability
If a double venting structure with multiple components is implemented, then vacuum prevention and spill prevention are improved, but the number of parts increases making cleaning difficult
Solution Approach 1:
Multiple venting components (first vent tube, second vent tube, valve mechanisms, and reservoir structures) are merged into a single integrated assembly that functions as one unified venting system. This combining maintains the reliability benefits of double venting while reducing the number of separate parts that need to be cleaned, as the entire assembly can be removed and cleaned as a single unit or with minimal disassembly.
Solution Approach 2:
The venting assembly is designed to perform multiple functions simultaneously: the first vent tube allows air intake, the second vent tube prevents vacuum, the valve mechanisms control flow directions, and the reservoir collects excess liquid. This multi-functionality reduces the need for separate components for each function, simplifying the overall structure while maintaining venting effectiveness and ease of cleaning.
3Productivity
If a vent tube is positioned to allow free pouring, then liquid flow is improved, but liquid leaks from the vent tube creating mess for the infant
Solution Approach 1:
The vent tube system incorporates localized quality variations: the first vent tube extends into the liquid to enable free pouring, while the second vent tube is positioned differently to prevent leakage. Additionally, valve mechanisms are placed at specific locations to control flow directions. This localized differentiation of tube positions and functions resolves the contradiction between improved liquid flow and leakage prevention.
Solution Approach 2:
The reservoir structure is designed to preliminarily collect and contain excess liquid that may enter the venting system during pouring. By providing this preliminary containment capacity, the system prevents liquid from leaking outward to create mess, while still allowing free pouring through the vent tubes. The reservoir acts as a buffer that captures potential leakage before it becomes a harmful external spill.
4Object-generated harmful factors
If the bottle requires specific orientation to prevent vent leakage, then spill prevention is improved, but the bottle cannot be used in various positions
Solution Approach 1:
The venting system incorporates dynamic elements including movable valve mechanisms that automatically adjust their position and opening based on the bottle's orientation and internal pressure conditions. This dynamic adaptation allows the system to maintain spill prevention functionality regardless of whether the bottle is held upright, tilted, or inverted, resolving the contradiction between spill prevention and orientation flexibility.
Solution Approach 2:
The vent tube system extends into the liquid in three-dimensional space, with tubes positioned at different depths and angles. This spatial arrangement creates multiple potential flow paths that remain functional across various orientations. By utilizing three-dimensional positioning rather than simple horizontal/vertical arrangements, the system maintains spill prevention while accommodating different usage positions.

AI summary
A vent prevents a vacuum from forming within an inverted container of liquid when the liquid is dispensed. The vent is a double vent, formed of a vent tube, upon which a reservoir and its integral vent tube locate, the reservoir securing with the vent tube that extends through the reservoir upper surface, to achieve the double venting of the interior of the container. The container is a nursing bottle, with a collar and nipple applied to the top, and the vent tube being integrally formed extending downwardly from the collar, and securing the reservoir and its integral tube thereon, when assembled for usage. The bottle may be formed of a transparent material, tinted to one coloration, while the reservoir and its reservoir tube may be tinted to a different coloration, which when they are assembled, exhibits a third coloration for the reservoir tube when viewed from exteriorly of the tinted nursing bottle during its application.
