Split Carton With Middle Tear Line For Confined Space Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carton designs, such as the 'FRIDGE PACK' carton, lack versatility when trying to access the dispenser section in confined spaces like refrigerator door shelves, requiring consumers to move the carton for easy article removal.
Innovation Solution
A carton design featuring a top wall with a handle cutout, side walls with middle tear lines, and a dispenser section that can be easily opened by tearing along curvilinear lines, allowing the carton to be split in half for improved accessibility and versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the carton is designed with a removable dispenser section for easy article removal, then ease of operation is improved, but the carton cannot be easily positioned in confined spaces like refrigerator door shelves
Solution Approach 1:
The carton is divided into two equal halves by a middle tear line that extends through the entire carton. This segmentation allows the carton to be easily separated into two accessible halves, enabling article removal without requiring the entire carton to be repositioned, thus resolving the contradiction between ease of operation and positioning versatility.
Solution Approach 2:
The invention introduces a new dimension of opening by adding a middle tear line that creates a horizontal separation plane. This allows the carton to be opened in a different dimension (horizontally splitting the carton) rather than requiring vertical repositioning or complex manipulation, thereby improving both accessibility and positioning flexibility.
2Ease of operation
If the dispenser section is positioned for optimal access in a standard refrigerator, then ease of operation is improved, but the carton cannot be easily placed in alternative locations such as refrigerator door shelves
Solution Approach 1:
The carton design serves multiple functions: it can be placed in standard refrigerator shelves, refrigerator door shelves, or other confined spaces. The middle tear line enables easy access to articles regardless of placement location, making the carton universally adaptable to different storage environments while maintaining ease of operation.
Solution Approach 2:
By segmenting the carton into two accessible halves through the middle tear line, the design ensures that articles remain easily accessible regardless of where the carton is placed. This segmentation decouples the access function from the placement location, allowing the carton to be universally positioned while maintaining operational ease.
3Volume of moving object
If the carton is designed to be compact for storage, then space efficiency is improved, but accessibility to the dispenser section becomes difficult
Solution Approach 1:
The carton is segmented into two accessible halves by the middle tear line, allowing compact storage while maintaining ease of access. Users can easily separate and access articles from either half of the carton, resolving the contradiction between compact size and accessibility.
Solution Approach 2:
The middle tear line creates a new dimensional opening that allows access to articles without requiring the user to manipulate or reposition the entire compact carton. This dimensional separation enables easy access while maintaining the carton's compact form factor.
