Liquid Storage Container Fitting Guide for Compact Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid storage containers face challenges in downsizing due to the need for multiple positioning portions to secure the connection between the liquid storage container and the supply member, which occupy significant space.
Innovation Solution
A liquid storage container design featuring a single positioning portion and a guide portion in the fitting portion to facilitate the alignment and secure fitting of the supply member, reducing the need for additional positioning constraints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple positioning portions are provided to position the supply port and connection portion, then positioning accuracy is improved, but the liquid storage container cannot be downsized
Solution Approach 1:
The patent combines multiple positioning functions into a single integrated positioning portion. The connection portion is designed with an inclined surface that simultaneously provides positioning guidance and rotational restriction, eliminating the need for separate positioning portions while maintaining positioning accuracy.
Solution Approach 2:
The connection portion serves multiple functions: it provides positioning guidance through its inclined surface, restricts rotation through its geometric constraints, and establishes fluid communication. This multi-functional design reduces the number of components needed for positioning.
2Device complexity
If a single positioning portion is used to downsize the liquid storage container, then device complexity is reduced, but positioning accuracy may deteriorate
Solution Approach 1:
The connection portion features a locally optimized inclined surface with specific geometric properties that provide sufficient positioning accuracy for the application. The local geometric design compensates for the reduced number of positioning portions.
Solution Approach 2:
The patent changes the geometric parameters of the connection portion, specifically the angle and dimensions of the inclined surface, to optimize positioning accuracy while maintaining a compact design with fewer positioning features.

AI summary
A liquid storage container including a positioning configuration contributing to downsizing is provided. The container capable of storing liquid therein includes a fitting portion including a communication port establishing communication between an inside and an outside, wherein a supply member supplying liquid is fitted and can supply the inside with liquid via the communication port; a first positioning portion positioning the supply member at one point; and a second positioning portion including a guide provided in the fitting portion and capable of guiding the supply member to a position where the supply member is fitted into the fitting portion when the supply member is fitted into the fitting portion while being positioned by the first positioning portion and a restriction portion restricting movement of the supply member using the first positioning portion as a rotation axis in the position where the supply member is fitted into the fitting portion.
