Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Universal dispensing spouts on baby food pouches are problematic due to their wide diameter, which leads to spills and limited control for young children, and the rigid structure with sharp corners poses a risk of injury from biting.

Innovation Solution

A protective spout cover made from flexible elastomer, such as silicone, that securely grips the spout, cushions it to prevent injuries, and includes a food regulating valve to control the flow of food, reducing spills and injuries.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a wide diameter dispensing spout is used for easy-flow of food, then food dispensing speed is improved, but spill control deteriorates

Engineering Contradiction:

Improvefood dispensing speedVSAvoidspill control

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The patent changes the flow control parameter from fixed (universal spout) to variable (adjustable valve mechanism). The valve can be opened wider for faster flow or partially closed for controlled dispensing, allowing adaptation to different feeding needs and preventing spills while maintaining dispensing speed capability.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent introduces a dynamic flow control valve that can adjust its opening degree during operation. This dynamic adjustment capability allows the spout to transition between high-speed dispensing and controlled flow, resolving the contradiction between productivity and ease of operation.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If pressure manipulation is increased for better flow control, then food flow regulation is improved, but motor skill requirements worsen

Engineering Contradiction:

Improvefood flow regulationVSAvoidmotor skill requirements

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent introduces a valve mechanism as an intermediary device between the pouch and the child. Instead of requiring the child to directly manipulate pressure, the valve provides a simple mechanical interface (turning or sliding motion) that controls flow, reducing the complexity of motor skills required while improving flow regulation.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Strength

If a rigid spout structure is used for safety during filling, then structural integrity is improved, but injury risk from biting worsens

Engineering Contradiction:

Improvestructural integrityVSAvoidinjury risk from biting

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the rigid spout structure with a flexible spout cover made of soft material. This flexible cover maintains structural integrity during filling through its elasticity while providing a soft, bite-safe surface that eliminates the injury risk from rigid corners, directly resolving the contradiction between strength and harmful factors.

Inventive Principle:

Principle #30Flexible shells and thin films

4Object-affected harmful factors

If a protective spout cover is added to prevent injuries, then safety is improved, but device complexity worsens

Engineering Contradiction:

Improveinjury preventionVSAvoidspout structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent merges multiple functions into a single integrated spout cover: protection (soft material), flow control (valve mechanism), and secure attachment (gripping features). By combining these functions into one component rather than adding separate devices, the patent improves safety while minimizing the increase in device complexity.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

Provided herein are protective spout covers adapted to couple to the universal dispensing spout of a food pouch, such as a baby food pouch. The protective spout covers may be formed from a flexible elastomer and may grip the spout securely via one or more gripping lips adapted to engage a corresponding groove on the universal spout. When so coupled, the protective spout cover may cushion the spout to protect the user's mouth and lips from injury. The protective spout cover also may include a food regulating valve that may control the flow of food from the pouch. The protective spout cover also may include a cap member to keep the protective spout cover clean when not in use, a gripping ring to facilitate use of the cap, and may have a size and durometer hardness sufficient to prevent the device from being a choking hazard.
