Liquid Storage Container Sheet Fastening for Easy Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid storage containers with adhesive labels for joining the case and lid face separation issues, leading to damage and reduced recycling rates, especially in high-temperature environments and requiring tools for disassembly.
Innovation Solution
A liquid storage container design featuring a housing with recesses and a sheet that surrounds the outer circumference, allowing the lid and case to be held together without direct bonding, facilitating easy separation and recycling, and maintaining the housing shape through thermal welding of the sheet's ends.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If an adhesive label is used to join the case and lid, then the case and lid are securely joined together, but the case and lid become difficult to separate and may be damaged during separation
Solution Approach 1:
A sheet member is introduced as an intermediary component between the case and lid. The sheet is joined to both the case and lid, creating a removable intermediate layer that secures the case and lid together during use but can be easily removed to separate the case and lid without damage.
2Strength
If an adhesive label is used to join the case and lid, then the case and lid are securely joined together, but tools are required to remove the adhesive label for separation
Solution Approach 1:
The sheet member serves as a removable intermediary that simplifies disassembly. It can be easily removed by hand without requiring any special tools, thereby reducing the complexity of the disassembly process while still providing secure joining during use.
3Strength
If an adhesive label is used to join the case and lid, then the case and lid are securely joined together, but the adhesive label becomes more securely stuck in high-temperature environments making removal difficult
Solution Approach 1:
The sheet member is designed to be removable even in high-temperature environments where adhesive labels would become permanently stuck. This makes the joining system adaptable to various temperature conditions, allowing easy separation regardless of thermal exposure during use or storage.

AI summary
A liquid storage container includes: a housing including a case having a case opening, and a lid that closes the case opening; and a sheet that holds the lid and the case together, the sheet extending over lid exterior faces and case exterior faces and being disposed so as to surround the outer circumference of the housing.
