Chamfered Corner Box Design for Stable Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing boxes used for packaging absorbent articles require significant manual effort for folding and erection, especially for larger boxes containing multiple flexible packages, and lack sufficient stability during stacking.
Innovation Solution
A box design featuring two chamfered corners with specific angles and overlapping flaps that form a stable structure, allowing for easy and precise folding and erection from a continuous blank of foldable sheet material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of stationary object
If boxes are made from thinner cardboard material to reduce cost and weight, then material cost and box weight are reduced, but box stability and resistance to deformation during stacking deteriorate
Solution Approach 1:
The box is divided into multiple panels (front, back, side panels) and corner panels that are interconnected through fold lines. This segmentation allows the box to maintain stability through its geometric structure rather than relying solely on thick material, enabling the use of thinner cardboard while preserving stacking strength.
Solution Approach 2:
The box incorporates corner panels at specific corners rather than uniform reinforcement throughout. This asymmetric placement of structural elements provides enhanced stability at critical stress points during stacking, allowing thinner material to be used in non-critical areas while maintaining overall box strength.
2Ease of operation
If manual folding and erection of large boxes is simplified to reduce labor effort, then ease of operation improves, but manufacturing precision and consistency may deteriorate
Solution Approach 1:
The box design includes pre-configured fold lines, creases, and panel arrangements that are prepared in advance on the blank sheet. This preliminary structuring guides the folding process, ensuring that even with reduced manual effort, the box maintains consistent precision and quality across production batches.
