Solution Overview

Problem

Existing packages are limited in shape complexity and cannot easily form triangular autobottoms, which restricts their geometric versatility.

Innovation Solution

A package design featuring a three-sided body formed of three or more body panels, with an autobottom connected to the body panels, allowing the autobottom to form a triangular shape that fully encloses the package's bottom opening.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If conventional package designs are used, then manufacturing simplicity is maintained, but shape complexity and geometric versatility are limited

Engineering Contradiction:
Improveshape complexityVSAvoidpackage structure complexity
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The package is divided into multiple body panels (first, second, third, and fourth body panels) that can be separately formed and then assembled together. This segmentation allows each panel to be manufactured using standard processes while the combination creates complex triangular geometries with autobottoms, resolving the contradiction between manufacturing simplicity and shape complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The autobottom structure is nested within the body panels, with bottom panels integrated into the panel assemblies. This nesting allows the complex triangular shape with enclosed bottoms to be formed from simpler individual components that can be manufactured separately, maintaining manufacturing simplicity while achieving geometric versatility.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Adaptability or versatility

If triangular autobottoms are formed, then geometric versatility is enhanced, but manufacturing complexity increases

Engineering Contradiction:
Improvegeometric versatilityVSAvoidmanufacturing ease
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The triangular package with autobottom is segmented into multiple body panels that can be manufactured using conventional processes. Each panel assembly can be produced independently with standard equipment, then assembled to form the complete triangular structure, maintaining manufacturing ease while achieving geometric versatility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The body panels are pre-formed with integrated bottom panels attached before final assembly. This preliminary action allows complex triangular geometries to be constructed from pre-prepared components, reducing the complexity of the final assembly process and maintaining manufacturing ease while achieving the desired geometric versatility.

Inventive Principle:
Principle #10Preliminary action

3Shape

If multiple body panels are used to form triangular shape, then shape complexity increases, but device complexity increases

Engineering Contradiction:
Improvetriangular shape complexityVSAvoidpanel assembly complexity
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

Multiple body panels are merged together through assembly operations to form the complete triangular package. The panels are designed to interconnect through standardized joints and attachments, allowing complex triangular shapes to be built from simpler individual components, thus increasing shape complexity while managing device complexity through modular design.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

Bottom panels are nested within and attached to the body panels, with the autobottom structure integrated into the overall panel assembly. This nesting reduces the number of separate components needed and simplifies the assembly process, allowing triangular shape complexity to increase without proportionally increasing device complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

In accordance with at least one aspect of this disclosure, a package can include a three-sided body formed of three or more body panels and an autobottom connected to the three-sided body and formed of three or more bottom panels extending from a respective body panel of the plurality of the three or more body panels. The autobottom can connect all of the three or more body panels together in a triangular shape when the three or more bottom panels are interacting with each other.
