Solution Overview

Problem

Conventional valving mechanisms for containers are large, cumbersome, and inefficient in venting air and preventing vacuum creation, failing to provide an effective spill-proof solution that allows for efficient priming and flow rate modulation during use.

Innovation Solution

A container assembly featuring an expandable nipple and a one-way vent valve that increases the volumetric area and allows for flexible fluid flow, using a resilient material to maintain a leak-proof seal and modulate fluid flow rates through the use of a one-way valve and accordion-style nipple design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional valving mechanisms are used, then air venting and vacuum prevention functions are provided, but the device size is large and assembly is cumbersome

Engineering Contradiction:
Improveair venting and vacuum preventionVSAvoiddevice size and assembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple valving functions (air venting, vacuum prevention, flow modulation) into a single integrated one-way valve mechanism located at the base of the nipple. This eliminates the need for separate vent valves and complex assembly, directly resolving the contradiction between functional reliability and device complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The one-way valve serves multiple functions simultaneously: it acts as an air vent, prevents vacuum formation, enables spill-proof operation, and allows flow rate modulation. This multi-functionality in a single component addresses the contradiction by providing comprehensive valving capabilities without increasing device size or assembly complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If conventional valving mechanisms are used, then basic venting function is provided, but flow rate modulation and spill-proof performance are insufficient

Engineering Contradiction:
Improvespill-proof performanceVSAvoidflow rate control
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent incorporates a collapsible reservoir and expandable nipple that dynamically adjust during feeding. The reservoir collapses to prevent spills when the bottle is tilted, while the nipple expands to maintain flow control. This dynamic adaptation resolves the contradiction between spill-proof reliability and ease of flow rate control.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The one-way valve allows caregivers to modulate flow rate by changing the opening size parameter. The valve can be adjusted to different opening degrees to control fluid flow, providing easy flow rate control while maintaining spill-proof performance through the same mechanism.

Inventive Principle:
Principle #35Parameter changes

3Stability of the object's composition

If rigid nipple design is used, then structural stability is provided, but adaptability to infant head alignment is poor

Engineering Contradiction:
Improvenipple structural stabilityVSAvoidadaptability to head alignment
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent uses an expandable nipple design that transitions from a compact stored state to an expanded feeding state. When expanded, the nipple becomes flexible and can adapt to various infant head alignments while maintaining structural integrity. This dynamic design resolves the contradiction between structural stability and adaptability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The expandable nipple is constructed from flexible material that allows it to bend and conform to different angles of infant head positioning. This flexibility maintains the nipple's structural composition while enabling adaptation to various orientations, directly addressing the contradiction between stability and versatility.

Inventive Principle:
Principle #30Flexible shells and thin films

4Reliability

If large valving mechanisms are integrated into the cap, then venting function is provided, but the overall device size and complexity increase

Engineering Contradiction:
Improveventing functionVSAvoidcontainer assembly size
Core Design Contradiction:
ReliabilityVSVolume of stationary object

Solution Approach 1:

The patent extracts the valving function from the cap structure and relocates it to a compact one-way valve at the nipple base. This extraction reduces the volume required for venting functionality in the main container assembly while maintaining effective air venting and vacuum prevention, resolving the contradiction between venting reliability and container size.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

An expandable container system including a container, an expandable nipple and a one-way valve. The expandable nipple is attached to the first end of the container and the valve is attached to a second end of the container. A counteracting bias force is generated within the container and a first fluid is drawn in through the valve by extending the expandable nipple. When the expandable nipple is released, the expandable nipple is biased back to an unextended state, and an increase in pressure created by the counteracting bias force induces a second fluid to flow out of an outlet in the expandable nipple.
