Detachable Liquid Holder Support for Printing Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid discharge apparatuses face challenges in efficiently replacing heavy liquid holders during dummy discharge operations, particularly in large-sized printing systems where the weight and height of the liquid holders make manual replacement cumbersome and inefficient.
Innovation Solution
The design incorporates a detachable liquid holder system with a support structure that allows the liquid holder to be displaced to a lower detachment position, facilitated by a slider and elastic members, enabling easier access and replacement without the need for additional framing or complex mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the liquid holder is installed at a high position to receive liquid from the discharge head, then the liquid discharge function is improved, but the replacement operation becomes difficult and requires more physical effort
Solution Approach 1:
The support structure is designed to be movable between a first position (high installation position) and a second position (low replacement position). The support can be shifted downward by operating members to enable easy replacement of the liquid holder at a lower position, then returned to the first position for normal operation. This dynamic positioning resolves the contradiction between maintaining high-position liquid discharge function and enabling easy replacement operation.
2Quantity of substance
If the liquid holder is made large to increase liquid storage capacity, then the liquid storage function is improved, but the weight increases making replacement more difficult
Solution Approach 1:
The movable support structure allows the liquid holder to be temporarily repositioned to a lower second position during replacement operations. This dynamic positioning reduces the physical effort required to handle heavy liquid holders with large storage capacity, resolving the contradiction between maintaining adequate liquid storage and enabling easy replacement despite increased weight.
3Ease of operation
If additional framing or complex mechanisms are added to facilitate liquid holder replacement, then the ease of replacement is improved, but the device complexity increases
Solution Approach 1:
The support structure serves multiple functions: it holds the liquid holder during normal operation, provides a lowering mechanism for easy replacement, and returns to its original position. The operating members are integrated into the existing structure rather than being separate complex mechanisms. This multi-functionality approach improves replacement ease without significantly increasing device complexity.

AI summary
A liquid discharge apparatus includes a head configured to discharge a liquid, and a discharge receptacle configured to receive the liquid discharged from the head at an installation position. The discharge receptacle includes a liquid holder configured to receive the liquid discharged from the head, and a support configured to detachably support the liquid holder. At least a part of the support is displaceable to a detachment position at which the liquid holder is detachable from the support, and the detachment position is lower than the installation position.
