Solution Overview

Problem

There is a need for a paperboard container that is stackable, structurally rigid, easy to set up, and minimizes material usage while maintaining a stable configuration during stacking, as existing containers often require additional reinforcing structures and waste material in their construction.

Innovation Solution

The development of an octagonal flush end container/tray with a mitered-bridging portion and a medial layer with horizontally arranged corrugation, which enhances stacking strength by sandwiching additional material between the inner and outer flaps, reducing waste and improving blank utilization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If multiple thicknesses and additional reinforcing structures are used in side and end walls, then structural strength and rigidity are improved, but device complexity and material usage increase

Engineering Contradiction:
Improvestructural strength and rigidityVSAvoiddevice complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The patent applies nesting by placing inner flaps within outer flaps to create reinforced corner structures. The inner flaps are positioned inside the outer flaps and secured thereto, forming a nested configuration that strengthens corners without adding external reinforcing structures. This nested arrangement provides structural reinforcement while maintaining simplicity in the overall container design.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Strength

If flutes of corrugated material are arranged to extend vertically, then structural strength is improved, but material usage increases

Engineering Contradiction:
Improvestructural strengthVSAvoidmaterial usage
Core Design Contradiction:
StrengthVSQuantity of substance

Solution Approach 1:

The patent applies local quality by orienting flutes horizontally in specific areas where strength is needed, rather than uniformly vertical orientation throughout. The flutes are arranged horizontally in the bottom wall and in the portions of side and end walls below the flaps, providing localized reinforcement where stacking loads are applied, while reducing overall material usage compared to uniform vertical flute orientation.

Inventive Principle:
Principle #3Local quality

3Strength

If overlapping corner flaps are used in traditional designs, then corner strength is improved, but material waste increases

Engineering Contradiction:
Improvecorner strengthVSAvoidmaterial waste
Core Design Contradiction:
StrengthVSLoss of substance

Solution Approach 1:

The patent applies discarding and recovering by eliminating the traditional overlapping corner flap configuration that creates scrap material. Instead, the design uses non-overlapping flaps with nested inner flaps secured to outer flaps, which maintains corner strength while preventing material waste. The blank is designed to utilize material efficiently without creating discarded scraps during the forming process.

Inventive Principle:
Principle #34Discarding and recovering

4Adaptability or versatility

If inner flaps are divided and shared with outer flaps, then four additional corners are provided, but structural complexity increases

Engineering Contradiction:
Improvecorner configurationVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the flaps into distinct inner and outer components. The inner flaps are separate from the outer flaps and are secured to the outer flaps, creating a segmented structure that forms reinforced corners. This segmentation provides the necessary corner configurations while maintaining clarity in the structural design and simplifying the manufacturing process compared to integrated flap designs.

Inventive Principle:
Principle #1Segmentation

AI summary

An article-transport container comprises a floor having a respective left-side and right-side closures that are foldably joined thereto. A front end wall is foldably joined to the floor and to the respective left-side and right-side closures. A rear end wall is foldably joined to the floor and to the respective left-side and right-side closures and at least one tri-layers corner cooperate with the respective left-side and right-side closures to define an interior region adapted to receive articles therein. The least one tri-layer corner includes respective outer and inner layers and a medical layer which is sandwiched between the respective outer and inner layers and a medical layer which is sandwiched between the respective outer and inner layers to enhance stacking strength of the container while minimizing scarps produced during construction of the container.
