Solution Overview

Problem

Conventional cartons with uniform corners often result in inefficient packing and movement of containers due to empty space and lack of flexibility during shipping, as well as uniform visual appearance which may not effectively display indicia or attract consumer attention.

Innovation Solution

Designing cartons with asymmetrical corners, such as a combination of rounded, oblique, and square configurations, which allow for tighter packing and movement of containers while providing an alternating visual effect that enhances display opportunities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional cartons with uniform corners are used, then manufacturing simplicity is maintained, but packing efficiency and container movement are reduced due to empty space

Engineering Contradiction:
Improvepacking efficiencyVSAvoidcorner configuration complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies asymmetry by configuring corners with different radii of curvature - specifically, first and third corners have a first radius while second and fourth corners have a second radius that is different from the first. This asymmetric corner design eliminates empty spaces between containers and the carton walls, thereby improving packing efficiency without significantly complicating the manufacturing process

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The patent applies local quality by making each corner have a different radius of curvature tailored to its specific position and function. The first and third corners have one radius while the second and fourth corners have another radius, allowing each corner to be optimized for its local packing requirements rather than using a uniform design throughout

Inventive Principle:
Principle #3Local quality

2Adaptability or versatility

If uniform corner configurations are used, then visual consistency is maintained, but consumer attention and indicia display effectiveness are reduced

Engineering Contradiction:
Improveindicia display effectivenessVSAvoidcorner uniformity
Core Design Contradiction:
Adaptability or versatilityVSShape

Solution Approach 1:

The asymmetric corner design creates visual interest and breaks the monotony of uniform corners, allowing for more effective display of indicia and advertisements. The alternating pattern of different corner radii creates a more engaging visual appearance that can attract consumer attention while still maintaining a regular, predictable structure

Inventive Principle:
Principle #4Asymmetry

3Productivity

If asymmetrical corners with different radii are used, then packing efficiency is improved, but manufacturing precision requirements increase

Engineering Contradiction:
Improvecontainer movement efficiencyVSAvoidcorner radius precision
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent implements asymmetry with two distinct radius values that can be easily distinguished and manufactured. The first radius for corners 1 and 3, and the second radius for corners 2 and 4, creates a pattern that is asymmetric enough to improve packing but simple enough to manufacture with standard precision equipment

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The corner design segments the carton into distinct zones with different radii, where corners 1 and 3 share one radius and corners 2 and 4 share another. This segmentation allows for modular manufacturing approaches and simplifies the precision requirements by grouping corners into two manageable categories rather than requiring unique precision for each corner

Inventive Principle:
Principle #1Segmentation

AI summary

A carton for containing a plurality of articles. The carton comprises a plurality of panels that extends at least partially around an interior of the carton. The plurality of panels comprises a top panel, a bottom panel, a first side panel, and a second side panel. The carton comprises a first corner and a second corner at a closed end. The first corner has a first configuration and the second corner has a second configuration, the first configuration being different than the second configuration so that the first corner and second corner are asymmetrical.
