Package Box With Multi-Side Engagement Structures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cartons typically offer limited open sides, making it inconvenient to retrieve heavy objects or those located at high heights, and may result in carton damage during extraction.
Innovation Solution
A package box design that can be opened from the top, right, or left side, featuring a foldable sheet material with multiple plate portions and engagement structures, allowing for flexible access and secure closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional carton is designed with only one or two open sides, then the structure is simple and easy to manufacture, but it is inconvenient for users to take out objects especially heavy objects or objects located at high heights
Solution Approach 1:
The carton is divided into multiple separable plate portions (front plate portion, rear plate portion, first top plate portion, second top plate portion, first right side plate portion, second right side plate portion, first left side plate portion, second left side plate portion) that can be independently opened through respective engagement structures, allowing access from multiple sides without requiring the entire carton structure to be complex
2Reliability
If the carton is too high or has limited open sides, then the structural integrity is maintained, but it may result in carton damage during the taking-out process of heavy objects
Solution Approach 1:
By segmenting the carton into multiple plate portions with independent engagement structures (top engagement structure, right engagement structure, left engagement structure), the design allows users to open only the necessary side for object retrieval, preventing damage to the entire carton structure while maintaining integrity of the closed portions
Solution Approach 2:
The engagement structures (top engagement structure, right engagement structure, left engagement structure) are extracted as separate functional elements that can be independently opened, allowing the useful action of object retrieval to be performed without compromising the overall carton integrity
3Adaptability or versatility
If a carton is designed specially for each object, then the object protection is optimized, but the use scope of the carton is limited
Solution Approach 1:
The carton design with multiple openable sides serves multiple functions: it can be opened from top, right, or left sides depending on the object being stored and retrieved, making a single carton design adaptable to various objects and usage scenarios rather than requiring specialized designs for each object type

AI summary
A package box includes two top plate portions at its top side, which are superimposed on each other and detachably fixed with each other through an engagement structure. The package box includes two right side plate portions at its right side, which are superimposed on each other and detachably fixed with each other through an engagement structure. The package box includes two left side plate portions at its left side, which are superimposed on each other and detachably fixed with each other through an engagement structure. The package box can be opened from the top side, the right side, or the left side after the corresponding engagement structure is opened. The package box can be formed by folding a foldable sheet material.
