Liquid Storage Body Restoration via Bag Communication Port
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid storage bodies for liquid ejection apparatuses are often discarded when the residual liquid amount decreases below a certain limit, leading to waste and increased operational costs, as the constituent parts remain functional but are not reused.
Innovation Solution
A manufacturing method for restoring liquid storage bodies by forming a communication portion in the bag, injecting liquid, and sealing it, allowing the storage body to be reused and attached to the liquid ejection apparatus, thereby extending its functionality and reducing waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If liquid storage bodies are discarded when residual liquid amount decreases below a predetermined lower limit amount, then the liquid ejection apparatus can maintain reliable operation, but functional parts are wasted and operational costs increase
Solution Approach 1:
The patent enables recovery and reuse of the liquid storage body after liquid depletion. The bag is collected by the collection member, restored to its original state, and reused, thereby preventing waste of functional parts while maintaining reliable operation through proper disposal of depleted liquid
Solution Approach 2:
The liquid storage body is designed to be self-contained with a collection member that automatically collects and restores the bag after liquid depletion, eliminating the need for manual intervention and enabling continuous reuse without additional operational costs
2Ease of operation
If the liquid storage body is designed with a width in the Z direction smaller than widths in the Y and X directions, then the storage body can be properly positioned and mounted in the liquid ejection apparatus, but the mounting precision requirement increases
Solution Approach 1:
The liquid storage body employs an asymmetric width configuration where the width in the Z direction (depth) is deliberately made smaller than the widths in the Y (height) and X (width) directions. This asymmetric design creates a unique dimensional signature that enables straightforward identification and mounting in the liquid ejection apparatus without requiring high precision, as the asymmetric shape naturally guides proper orientation during installation

AI summary
A manufacturing method of a liquid storage body includes: preparing a pre-restored storage body that has a bag to which a connection member is attached, and that is thereby sealed, the connection member being provided with a liquid outlet port, a storage-body-side electrical connection portion, a first receiving portion that receives a first positioning portion, and a second receiving portion that receives a second positioning portion; forming a communication portion that is in communication with the internal space of the bag by processing the bag; injecting a liquid from the communication portion into the internal space of the bag; and closing the communication portion so as to seal the bag.
