Liquid Housing Body Recycling Method with Filter Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid housing containers with filters inside face challenges in recycling without damaging the filter, as existing methods do not provide a constitution for injecting liquid without harming the filter during the recycling process.
Innovation Solution
A recycling method for liquid housing bodies with filters involves forming an opening outside the filter area, injecting liquid through this opening, and then sealing it, ensuring the filter is not damaged during the recycling process. This method includes forming an opening on the liquid housing unit outside the area facing the filter, injecting liquid, and sealing the opening to prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If liquid is injected into the liquid housing unit through the supply port during recycling, then the liquid housing body can be refilled, but the filter may be damaged
Solution Approach 1:
The liquid housing unit is segmented into two functional areas: the supply port region for liquid injection and the filter region for filtration. By creating a separate injection port distinct from the supply port, the system allows liquid refilling without directing injection flow through the filter, thus preventing filter damage while maintaining recycling efficiency
Solution Approach 2:
A separate injection port is introduced as an intermediary structure that enables liquid injection without involving the filter. This intermediary port provides a dedicated pathway for recycling operations, isolating the filter from the injection process and allowing both refilling and filtration functions to coexist without interference
2Device complexity
If the supply port is used for both liquid supply and recycling injection, then the device structure is simplified, but the filter cannot be protected during injection
Solution Approach 1:
The port system is segmented into two distinct ports: the supply port for normal liquid discharge through the filter, and a separate injection port for recycling operations. This segmentation prevents the harmful interaction between injection flow and the filter while maintaining overall structural simplicity
Solution Approach 2:
Instead of using the supply port for injection (which would expose the filter to damage), the system inverts the approach by creating a dedicated injection port that bypasses the filter entirely. This inversion of the normal flow path protects the filter while enabling recycling functionality

AI summary
A liquid housing body recycling method is provided for a liquid housing body that includes a liquid housing unit that is configured to house liquid, a supply member with a supply port that is configured to be connected to a liquid supply tube of a liquid consuming device, and a filter through which the liquid is configured to pass, with the liquid inside the liquid housing unit being supplied to the liquid consuming device via the supply port by passing through the filter. The liquid housing body recycling method includes forming an opening part on the liquid housing unit at a position outside an area facing opposite the filter on the liquid housing unit, injecting the liquid from the opening part of the liquid housing unit on which the opening part has been formed, and sealing the opening part.
