Solution Overview

Problem

Ostomy barrier ring packages often topple when stacked due to lack of positive positioning features, leading to instability and potential accidents.

Innovation Solution

A stackable clamshell package design with nesting structures and a hinge mechanism that allows shells to rotate between open and closed positions, featuring lugs and grooves for secure closure and nesting configurations to prevent toppling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If individual barrier ring packages are stacked for storage, then storage space utilization is improved, but the stack becomes unstable and may topple

Engineering Contradiction:
Improvestorage capacityVSAvoidstack stability
Core Design Contradiction:
Quantity of substanceVSStability of the object's composition

Solution Approach 1:

The patent implements nesting structures consisting of outwardly extending lugs on one shell and corresponding grooves on the opposing shell. These features interlock when packages are stacked, with the lugs of one package fitting into the grooves of the package below, creating a nested configuration that provides positive positioning and prevents toppling while maximizing storage space utilization.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of operation

If a hinge mechanism is used to allow package opening, then ease of operation is improved, but the package may accidentally open

Engineering Contradiction:
Improvepackage openingVSAvoidaccidental opening prevention
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The hinge mechanism is designed with pre-positioned lugs and grooves that engage before the package is fully opened. This preliminary engagement action secures the package in a stable intermediate position, preventing accidental opening while still allowing intentional opening when needed. The nesting structures are pre-configured to interlock, providing stability before complete deployment.

Inventive Principle:
Principle #10Preliminary action

AI summary

A package for an ostomy barrier ring is provided. The package includes a first shell, a second shell and a hinge connecting the first and second shells. The first shell includes a first stacking wall having a first interior side and a first exterior side, a first nesting structure formed on the first stacking wall, and a first sidewall extending from and about the first stacking wall. The second shell includes a second stacking wall having a second interior side and a second exterior side, a second nesting structure formed on the second stacking wall, and a second sidewall extending from and about the second stacking wall. The hinge allows the first shell and second shell to rotate relative to one another. A plurality of packages may be stacked with the first nesting structure of one package received in the second nesting structure of an adjacent package.
