Tissue Paper Container with Nested Connection for Easy Refilling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing home tissue paper accommodation containers require significant effort to refill due to the need to lift, turn over, and open the container body, and integrally forming the upper and lower parts with a connection portion results in a protrusion that affects appearance and functionality.
Innovation Solution
A home tissue paper accommodation container design featuring a detachably assembled upper and lower container body with a connection portion that is integrally formed but positioned to minimize protrusion, allowing for easier refilling and improved airtightness, while maintaining manufacturing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the upper container body and lower container body are formed separately and connected, then the container can be detachably assembled for easy refilling, but the connection portion protrudes to the outside affecting appearance
Solution Approach 1:
The container body is divided into an upper container body and a lower container body that can be detachably assembled. This segmentation allows the container to be opened at the middle for refilling without needing to lift or turn over the entire container, improving ease of operation while maintaining a relatively smooth external appearance through proper design of the connection portion
Solution Approach 2:
The connection portion is designed to be positioned inside the accommodation space rather than protruding outward. The upper and lower container bodies are connected in a nested manner where the connection structure is concealed within the container's internal volume, eliminating the appearance defect while preserving the detachable assembly function
2Productivity
If the upper container body and lower container body are integrally formed, then manufacturing efficiency is improved, but it is difficult to consider the structure of a mold for direct connection
Solution Approach 1:
The container body is segmented into upper and lower parts that are integrally formed through a single molding process. This segmentation allows the mold to be designed with separate cavities for each part while maintaining integral formation, solving both the manufacturing efficiency requirement and the mold structure constraint
Solution Approach 2:
The connection portion is positioned in the internal dimension (inside the accommodation space) rather than extending in the external dimension. This dimensional repositioning allows integral formation without requiring complex external mold structures, as the connection features can be formed internally during the molding process
3Shape
If the connection portion is positioned to minimize protrusion, then appearance is improved, but the connection portion length must be precisely controlled
Solution Approach 1:
The connection portion is nested within the accommodation space, utilizing the internal volume of the container. This nesting approach naturally limits the connection portion length to the available internal depth, eliminating the need for precise external length control while maintaining a smooth appearance
Solution Approach 2:
The connection portion is designed to extend equally from both the upper and lower container bodies toward the center of the accommodation space. This equipotential design distributes the connection length symmetrically, reducing manufacturing precision requirements as any variation tends to balance out from both sides

AI summary
A home tissue paper accommodation container includes a container body having an accommodation space. The container body includes a container body upper part and a container body lower part which are connected to each other by a connection part and integrally formed. The container body upper part and the container body lower part can be detachably combined with respect to each other so as to seal the accommodation space. The connection part connects surfaces oriented in the same direction in a state in which the container body upper part and the container body lower part are combined with each other. The connection part connects a position separated from the lower end of the container body upper part and a position separated from the upper end of the container body lower part to each other.
