Liquid Container Screw-Fixed Adapter Assembly for Stable Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid containers that attach members via snap-fitting often suffer from reduced rigidity, leading to unintentional detachment, damage, or positional deviations, which can cause connection failures and liquid leaks.
Innovation Solution
A liquid container design that incorporates a screw member to fix the supply member and adapter, supplemented by a snap-fitting mechanism, ensuring stable attachment and reducing positional deviations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If members are attached to each other by snap-fitting, then the attachment process is simple and quick, but the rigidity of the attachment is lower and unintentional release may occur
Solution Approach 1:
The attachment system is divided into two functional segments: snap-fitting for quick attachment and screw members for securing. The snap-fitting portion (144) provides initial attachment while the screw member (103) provides definitive securing, allowing each segment to optimize for its specific function without compromising the other.
Solution Approach 2:
The patent combines two attachment mechanisms (snap-fitting and screw fastening) into a unified attachment system. The snap-fitting portion (144) and screw member (103) work together to achieve both quick attachment and secure fixation, merging the advantages of both methods into a single integrated solution.
2Productivity
If members are attached to each other by snap-fitting, then the assembly process is fast, but positional deviation between members may occur
Solution Approach 1:
The snap-fitting mechanism performs preliminary positioning and alignment of the supply path member (101) and adapter (102) before the screw member (103) is inserted. This preliminary action ensures that the members are correctly positioned, and the screw member then secures them in place, preventing positional deviation while maintaining fast assembly.
3Device complexity
If snap-fitting is used for attachment, then the structure is simpler, but the portions constituting the snap fit are more prone to damage
Solution Approach 1:
The attachment structure is segmented into a snap-fitting portion (144) that provides simple, low-complexity attachment and a screw member (103) that provides high-strength securing. By dividing the attachment function into two segments with different complexity levels, the system achieves both structural simplicity and attachment strength.
Solution Approach 2:
The screw member (103) acts as an intermediary element that bridges the snap-fitting portion (144) and the supply path member (101)-adapter (102) connection. This intermediary provides the additional strength needed to prevent damage while maintaining the simplicity of the snap-fitting design.

AI summary
A liquid container includes a liquid containing bag including a bag main body for containing a liquid and a supply member that is attached to one end portion side of the bag main body and that includes a liquid supply portion, an adapter disposed on the one end portion side of the bag main body, and a screw member that fixes the supply member and the adapter.
