Solution Overview

Problem

The production of erectable folding boxes with internal partitions faces challenges due to restoring forces that hinder easy erection and closure, especially when the adhesive is not fully dry, leading to undesirable shapes and increased production complexity.

Innovation Solution

A blank design featuring a body section, collar portion, and divider portion, where the collar section is loosely held between the body and divider sections, allowing for sliding and reducing restoring forces, enabling easier erection and closure without additional gluing steps.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the collar section is firmly glued to the body section and separating section, then the packaging structure is more stable, but restoring forces increase making erection and closure difficult

Engineering Contradiction:
Improvestructural stabilityVSAvoiderection ease
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The collar section is designed to be movable relative to the body section and separating section, transitioning from a static firmly glued state to a dynamic state where it can move during erection and then be secured in the final position. This allows the packaging to be easily erected while maintaining structural stability when closed.

Inventive Principle:
Principle #15Dynamics

2Stability of the object's composition

If the collar section is firmly glued to the body section and separating section, then the packaging structure is more stable, but additional gluing steps and production complexity increase

Engineering Contradiction:
Improvestructural stabilityVSAvoidproduction complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The collar section is designed to automatically position itself and be retained between the body section and separating section through its own geometric features and interaction with the other sections, eliminating the need for additional gluing steps or complex assembly devices. The structure serves itself by using the natural stacking and fitting of sections.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If the collar section is loosely held between body and divider sections, then erection and closure become easier, but structural stability may be compromised

Engineering Contradiction:
Improveclosure easeVSAvoidstructural stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The collar section transitions from a loosely held state during erection to a secured state in the final closed packaging, where it is retained between the body section and separating section. This dynamic positioning provides ease of operation during assembly while ensuring structural stability in the finished product.

Inventive Principle:
Principle #15Dynamics
