Liquid Housing Container Recycling Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Recycling of liquid housing containers is challenging due to swelling issues when the initial liquid volume is injected, making it difficult to rehouse the container within the case member after the liquid is depleted, as the volume exceeds the initially housed capacity.
Innovation Solution
A recycling method involving the removal of the second case member, forming an opening part on the liquid housing body, injecting a volume of liquid smaller than the initially housed volume, and sealing it to facilitate rehousing within the case member, while using orientations to exhaust air bubbles effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the liquid housing body is taken out from the case member for liquid injection, then the opening part can be formed to communicate with the liquid housing unit, but the volume of liquid injected may exceed the initially housed volume causing the liquid housing unit to swell beyond the case member capacity
Solution Approach 1:
The patent applies preliminary action by forming the opening part on the liquid housing body before injecting liquid. This allows controlled liquid injection while preventing overfilling, as the opening part enables monitoring and regulation of the liquid volume being injected into the flexible liquid housing unit.
Solution Approach 2:
The patent changes the physical state by transitioning the liquid housing unit from a contracted state (when empty) to a partially expanded state (when filled with controlled volume). By controlling the liquid volume parameter to be less than the initially housed volume, the unit expands enough to contain liquid but remains within the case member's capacity constraints.
2Ease of repair
If the liquid housing body is removed from the case member for recycling, then liquid can be injected into the liquid housing unit, but the case member must be dismantled or the liquid housing body must be reinserted
Solution Approach 1:
The patent applies segmentation by separating the liquid housing body from the case member for the specific purpose of liquid injection, then reassembling them. The opening part formed on the liquid housing body allows liquid injection to be performed on the removed housing body, after which it can be reinserted into the case member without dismantling the case member itself.
Solution Approach 2:
The patent applies the taking out principle by extracting the liquid housing body from the case member to perform the opening formation and liquid injection operations. This allows the liquid refilling process to be performed on the isolated housing body, simplifying the injection process while maintaining the integrity of the case member structure.
3Measurement precision
If air bubbles remain in the liquid housing unit after liquid injection, then the liquid volume detection becomes inaccurate, but requiring specific orientations and air bubble exhaustion processes
Solution Approach 1:
The patent applies preliminary action by positioning the opening part at a specific location and orientation during liquid injection to facilitate air bubble exhaustion. This preliminary positioning ensures that air bubbles can escape during the injection process, preventing them from remaining in the liquid housing unit and interfering with accurate volume detection.

AI summary
The liquid housing container recycling method includes removing a second case member from a first case member, taking out a liquid housing body from inside of the first case member, forming on the liquid housing body an opening part that communicates with inside of a liquid housing unit, injecting into the inside of the liquid housing unit from the opening part that is formed liquid of a volume that is smaller than an initially housed volume when the liquid is initially injected and housed in the liquid housing unit of the liquid housing body in a state of being housed inside the case member, sealing the opening part of the liquid housing body, housing inside the first case member the liquid housing body for which the opening part is sealed, and attaching the second case member to the first case member.
