Solution Overview

Problem

Existing water dispensers face challenges with heavy five-gallon water bottles, leakage issues with water retaining bags, and difficulty in replacing bags in bottom-loading systems, as well as inefficiencies in puncturing and dispensing from liquid retaining bags.

Innovation Solution

An apparatus with a liquid transport conduit oriented at an acute angle and a guide and retaining member that facilitates puncturing of the liquid retaining bag adjacent its sidewall, allowing for easy removal and replacement of bags while maintaining the conduit's position, using a storage container with a collapsible bag and a spike with uniformly spaced openings for secure dispensing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a spike is used to puncture the water retaining bag from above, then the bag can be secured for dispensing, but the spike cannot be readily removed and replaced with another bag

Engineering Contradiction:
Improvebag replacement capabilityVSAvoidconduit removal and reinstallation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The puncturing function is segmented from the dispensing function. The spike is used only for initial puncturing, then removed, allowing the conduit to be repositioned for subsequent dispensing operations without requiring spike removal and reinstallation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The bag is punctured in advance using the spike before the conduit is installed. This preliminary puncturing action allows the conduit to be positioned optimally for dispensing without the constraint of having to accommodate the spike's position throughout the entire dispensing cycle.

Inventive Principle:
Principle #10Preliminary action

2Ease of manufacture

If the liquid transport conduit is positioned vertically, then installation is simple, but puncturing adjacent to the sidewall is difficult

Engineering Contradiction:
Improveconduit installation easeVSAvoidbag puncturing effectiveness
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The conduit is designed with flexibility to change its position and orientation. It can be positioned at an angle during installation to facilitate sidewall puncturing, then adjusted to a vertical orientation for optimal dispensing operation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The conduit's angular parameter is changed during the installation process. It is initially positioned at an angle to enable effective sidewall puncturing, then repositioned to a vertical orientation for the dispensing phase, optimizing both puncturing and dispensing functions.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If pumps are used to dispense water from below, then heavy bottles can be stored at the bottom, but the system becomes more complex

Engineering Contradiction:
Improvewater bottle mounting easeVSAvoidpump system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The pump is extracted from the system entirely. Instead of using mechanical pumping to move water from below, the system uses gravity flow by positioning the conduit to draw water downward from the bag, eliminating the need for complex pumping mechanisms while maintaining bottom-loading functionality.

Inventive Principle:
Principle #2Taking out (Extraction)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

AI summary

An apparatus configured to store and dispense liquid from a liquid retaining bag (B). The apparatus preferably includes a storage container (24) for storing the liquid retaining bag (B). The liquid storage container (24) and the liquid retaining bag (B) are preferably housed in the bottom of a water cooler. The storage container (24) includes a base (26), an upper opening and at least one wall (28) extending upwardly from the base (26) and defining a hollow cavity (8). The hollow cavity (8) is sized to receive a liquid retaining bag (B). The apparatus further includes a liquid transport conduit (4, 6) for transporting liquid from the liquid retaining bag (B) to a dispensing location. A guide and retaining member (34) is operably associated with the storage container (B). The guide and retaining member (B) is configured to guide the liquid transport conduit (4, 6) from a first location to a second location. The second location is an operating position in which at least a portion of the liquid transport conduit (4, 6) extends into the liquid retaining bag and the first location is a location where no portion of the liquid transport conduit is within the liquid retaining bag.
