Capsule Container Joint Length for Secure Yet Easy Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing article accommodation containers, such as those described in Japanese Utility Patent Application Publication No. S53-110977, lack a user-friendly configuration that allows easy opening and secure closure, particularly for small children, and do not maintain the enclosed article during manufacturing and use.
Innovation Solution
An article accommodation container comprising a body portion made of two main components, where one component has a projecting portion that connects with the other, with a length of the projecting portion being ⅕ to ⅓ of the maximum diameter of the body portion, allowing for a stable and easy connection and disconnection mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the capsule is designed to be securely closed during manufacturing, then the reliability of article containment is improved, but the ease of operation for opening becomes difficult
Solution Approach 1:
The capsule is divided into two separate hemispherical parts that can be connected and disconnected. The connecting portion includes a projecting part on one hemisphere that fits into a recess on the other hemisphere, allowing the capsule to be securely assembled during manufacturing while enabling easy separation by small children through simple pulling motion.
Solution Approach 2:
The connecting portion acts as an intermediary mechanism between the two hemispherical parts. It provides a controlled interface that maintains secure containment when connected but allows easy opening when disconnected, resolving the contradiction between security and ease of operation.
2Device complexity
If the connecting portion is made short for simple structure, then the device complexity is reduced, but the reliability of maintaining enclosed article during manufacturing deteriorates
Solution Approach 1:
The length of the projecting part in the connecting portion is specifically set to 1/5 or more of the maximum diameter of the body portion. This parameter change ensures that the connecting portion is long enough to provide reliable containment during manufacturing and transport, while maintaining a relatively simple overall structure.
3Reliability
If the projecting portion is made long for secure connection, then the reliability of connection is improved, but the device complexity increases
Solution Approach 1:
The length of the projecting portion is optimized to be 1/5 or more of the maximum diameter of the body portion. This specific parameter range provides sufficient connection stability for secure containment while avoiding excessive length that would increase structural complexity and make the capsule cumbersome.

AI summary
An article accommodating container comprises a body portion which includes a first main component and a second main component, which can be connected to each other, wherein the first main component comprises a main body and a projecting portion, which projects from the main body and forms a connecting portion to be connected to the second main component, and a length of the projecting portion in a connecting direction of the first main component and the second main component is ⅕ or more of a length of a maximum diameter of the body portion in a connected state.
