Household tissue storage container
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing household tissue storage containers risk the latch coming off when mistakenly pressed, leading to unintended opening.
Innovation Solution
A household tissue storage container design featuring an integrated upper and lower container main body with a connector, a button and ribs that prevent the latch from detaching, using injection molding to ensure structural integrity and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the latch is a separate body attached to the container main body, then the ease of manufacture is improved, but the reliability deteriorates because the latch may come off when mistakenly pressed
Solution Approach 1:
The latch and container main body are merged into a single integrated structure through injection molding. The latch is formed as an integral part of the container main body, eliminating the separate attachment process while maintaining manufacturing efficiency. This integration ensures that the latch cannot detach accidentally, resolving the reliability issue while preserving ease of manufacture through single-step molding.
2Ease of manufacture
If the button is attached to the upper container main body with simple fitting, then the ease of manufacture is improved, but the reliability deteriorates because the button may detach when mistakenly pressed
Solution Approach 1:
The button and button attaching portion feature asymmetric rib structures with varying heights and positions. The multiple ribs of different heights create an asymmetric fitting pattern that prevents the button from detaching in any direction except the intended pressing direction. This asymmetric design maintains simple injection molding manufacturing while significantly improving the button's retention reliability.
3Ease of operation
If the container main body is divided into upper and lower portions, then the ease of operation is improved for refilling, but the device complexity increases
Solution Approach 1:
The container main body is segmented into an upper container main body and a lower container main body that can be separated from each other. This segmentation allows easy refilling of the tissue package by removing the upper portion, while the connector design with positioning ribs and grooves ensures simple reassembly. The segmentation improves ease of operation without significantly increasing device complexity through straightforward modular construction.

AI summary
This household tissue storage container 1 comprises a container body 10 having a storage space S inside which household tissue paper P is stored, wherein the container body 10 comprises: a container body upper part 11; a container body lower part 12; a connection part 13 connecting the rear surface of the container body upper part 11 and the rear surface of the container body lower part 12; an opening/closing lid 2 which opens/closes a take-out hole 113a for taking out the household tissue paper; and a button part 3 for opening/closing the opening/closing lid 2. A plurality of body-side ribs 1163 are formed on the front surface side of the outer surface of a body-side fitting part 1161 of a button attachment part 116 to which the button part 3 is attached, and a plurality of button-side ribs 34 are formed on the front side of a button-side fitting part 32 that protrudes downward from an upper surface part 31 of the button part 3. During attachment of the button part 3, the button-side ribs 34 are inserted through and fitted between the adjacent body-side ribs 1163, 1163.
