Package With Segmented Rigidity For Controlled Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging containers deform excessively when opened, potentially damaging the contents due to the force required to break the weak portion, leading to inadequate protection of the merchandise.
Innovation Solution
A package designed with a flexible sheet material, featuring a hinge that connects two sides which pivot for opening, incorporating a first and second fitting portion with varying rigidity sections to allow controlled opening without excessive deformation, ensuring the contents are protected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a weak portion is provided to enable easy opening and confirmation of malicious opening, then the packaging container can be opened readily and opening can be confirmed, but excessive force deforms the packaging container and may damage the merchandise
Solution Approach 1:
The packaging container is segmented into multiple functional portions: a rigid portion that maintains structural integrity, a weak portion that breaks to indicate opening, and a fitting portion that enables controlled separation. This segmentation allows the container to open easily while protecting the merchandise from excessive deformation.
Solution Approach 2:
Different portions of the packaging container have different rigidity characteristics. The rigid portion maintains overall structural integrity, while the weak portion is specifically designed with lower rigidity to break at controlled locations. This local differentiation of mechanical properties enables easy opening without damaging the merchandise.
2Reliability
If the weak portion is designed to break during opening to confirm malicious opening, then opening confirmation is achieved, but the force required may greatly deform the packaging container
Solution Approach 1:
The container structure is divided into distinct functional segments including a weak portion specifically designed for breaking to indicate opening, while other portions maintain structural integrity. This segmentation ensures reliable opening confirmation without compromising the overall shape and protecting the merchandise.
Solution Approach 2:
The rigidity parameter is varied across different portions of the packaging container. The weak portion has lower rigidity to break easily for opening confirmation, while the rigid portion maintains higher rigidity to preserve the container's shape and protect the merchandise during the opening process.
3Object-affected harmful factors
If a rigid structure is used to protect the merchandise, then the merchandise is protected from deformation, but the packaging container cannot be opened easily due to excessive force requirements
Solution Approach 1:
The packaging container is segmented into a rigid portion for merchandise protection and a weak portion for easy opening. The rigid portion maintains structural integrity to protect the merchandise, while the weak portion is designed with lower strength to break easily, enabling convenient opening without requiring excessive force.
Solution Approach 2:
Different portions of the packaging container have different mechanical properties. The rigid portion provides structural support and merchandise protection, while the weak portion has locally reduced rigidity and strength to enable easy opening. This local differentiation resolves the contradiction between protection and ease of opening.

AI summary
A package includes a first side, a second side and a hinge. As the first side and the second side pivot around the hinge, the first side and the second side make transition between a closed state and an opened state. The first side includes a first fitting portion in a projecting shape, a rigid portion provided in a partial section on a line that goes around the first fitting portion, and a first weak portion provided in a remaining section on the line that goes around the first fitting portion and being lower in rigidity than the rigid portion. The second side includes a second fitting portion in a recessed shape and fitted to the first fitting portion in the closed state and a second weak portion provided on a line that goes around the second fitting portion and being lower in rigidity than the rigid portion.
