Modular Ink Supply Unit Layout for Compact Stable Liquid Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inkjet recording apparatuses lack a modular and efficient system for attaching and detaching ink supply and collection tanks, which are independent of a box-like ink tank guide, limiting flexibility and increasing the size of the apparatus.
Innovation Solution
A detachable liquid supply unit comprising a support that attaches to an apparatus body, incorporating a supply tank and a collection tank, allowing for easy mounting and detachment, and includes a frame structure that optimizes space usage and maintains pressure differentials for stable liquid flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the supply tank and collection tank are made independent and detachable from the apparatus body, then the flexibility and ease of maintenance are improved, but the device complexity increases due to the need for separate support structures and attachment mechanisms
Solution Approach 1:
The patent combines the supply tank, collection tank, and support structure into an integrated liquid supply unit. This merging allows the tanks to be detachable from the apparatus body while sharing common support structures and attachment mechanisms, thereby improving ease of maintenance without proportionally increasing device complexity.
Solution Approach 2:
The liquid supply unit is designed as a separate modular component that can be detached from the apparatus body. This segmentation enables independent maintenance and replacement of the tank system without affecting the main recording apparatus, improving ease of maintenance while the shared support structure minimizes the increase in overall device complexity.
2Volume of moving object
If the supply tank and collection tank are positioned close to each other to reduce apparatus size, then the volume of the apparatus is reduced, but the stability of liquid flow may be compromised due to interference between the tanks
Solution Approach 1:
The patent positions the supply tank and collection tank in different spatial dimensions and orientations, with the supply tank extending in a first direction and the collection tank extending in a second direction different from the first. This dimensional arrangement allows close positioning for compact volume while maintaining separate liquid flow paths that prevent interference, thus preserving liquid flow stability.
Solution Approach 2:
The patent applies different structural characteristics to different parts of the tank system. The supply tank and collection tank have different extension directions and are supported at different locations on the support structure. This local differentiation allows optimized spatial arrangement for compact volume while maintaining independent, stable liquid flow paths for each tank.
3Adaptability or versatility
If the tanks are attached to a support structure that extends in multiple directions, then the adaptability and versatility of the liquid supply unit are improved, but the manufacturing complexity increases
Solution Approach 1:
The support structure is designed with multiple extension directions and universal attachment capabilities that can accommodate different tank configurations and orientations. This multi-functional support structure provides adaptability for various liquid supply unit arrangements while being manufactured as a single integrated component, balancing versatility with manufacturing simplicity.

AI summary
A liquid supply unit includes a supply tank that stores a liquid to be supplied to a supply destination, a collection tank that stores the liquid collected from the supply destination, and a support that supports the supply tank and the collection tank. The support is detachably attachable to an apparatus body including the supply destination.
