Solution Overview

Problem

Existing pouring spout systems do not effectively allow for pouring stored contents in a safe, convenient, and economical manner.

Innovation Solution

A pouring spout system comprising a bag with a fixed and movable component, where the movable component slides or pivots to facilitate pouring, and an adhesive for attachment, ensuring safe and convenient use while being cost-effective to manufacture and market.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional pouring spout system is used, then the structure is simple, but the pouring safety and convenience are insufficient

Engineering Contradiction:

Improvepouring safetyVSAvoidspout system structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The spout system incorporates a movable component that can transition between retracted and extended positions. When the bag is full, the spout is retracted to prevent leakage. When pouring is needed, the spout extends to allow controlled flow. This dynamic adjustment mechanism resolves the contradiction by adding movement capability to an otherwise simple structure, improving pouring safety without excessive complexity.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The spout system is divided into distinct components: a fixed component attached to the bag and a movable component that can independently position the spout opening. This segmentation allows the movable portion to be optimized for pouring control while the fixed portion maintains structural simplicity, thereby improving reliability without uniformly increasing overall device complexity.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If a movable component is added to improve pouring convenience, then the ease of operation increases, but the manufacturing cost increases

Engineering Contradiction:

Improvepouring convenienceVSAvoidmanufacturing cost

Core Design Contradiction:

Ease of operationVSEase of manufacture

Solution Approach 1:

The movable component utilizes flexible materials and thin-film structures that can be easily formed through standard manufacturing processes. The spout mechanism relies on material flexibility rather than complex mechanical assemblies, reducing manufacturing complexity and cost while still enabling convenient pouring operation through simple actuation.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The spout system is designed as a disposable component integrated with the bag, eliminating the need for expensive, durable materials and complex assembly processes. By optimizing for low-cost manufacturing rather than long-term durability, the system achieves ease of operation at minimal manufacturing cost, aligning with single-use packaging economics.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

AI summary

A pouring device is for use with a bag having an open top and a closed bottom and side walls between the open top and the closed bottom, the bag having a domain between the side walls laterally and the open top and closed bottom elevationally for contents to be poured. The pouring device is located within the domain. The pouring device includes a fixed component and a movable component.
