Rotatable Lid Ink Carriage Prevents Scattering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ink scattering occurs when the ink injecting unit is inserted into or removed from the connection port in printers, making it difficult to clean ink adhered to the carriage and surrounding areas.
Innovation Solution
A printer design featuring a rotatable lid member on the carriage that exposes or conceals the ink storage unit's supply port, allowing the lid member to position itself to limit removal of the ink storage unit, cover scattered ink, and facilitate cleaning by moving to different positions based on the operational state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a wall for preventing ink scattering is provided to the carriage, then ink scattering is reduced, but it becomes difficult to clean the ink adhered to the wall and surrounding areas
Solution Approach 1:
The lid member is made rotatable between a first position (covering the supply port) and a second position (exposed for cleaning). This dynamic configuration allows the lid to function as an ink scattering barrier during operation, while being movable to facilitate easy cleaning when needed.
2Ease of operation
If the supply port is exposed for ink injection, then ink can be supplied to the sub-tank, but ink may scatter during the injection process
Solution Approach 1:
The lid member can be rotated to a first position that covers the supply port during ink injection, preventing ink scattering while still allowing ink to be supplied through the connection port. When cleaning is needed, the lid rotates to a second position exposing the supply port for easy access.

AI summary
A printer includes a carriage in which a discharging head configured to discharge ink and an ink storage unit configured to store the ink to be supplied to the discharging head are mounted, and a lid member provided to the carriage. The lid member is rotatable to a first position and a second position, when the lid member is located at the first position, a supply port included in the ink storage unit is exposed, a first portion is located above the ink storage unit so as to limit removal of the ink storage unit from the carriage, and a lower end of a second portion is located below the supply port, and when the lid member is located at the second position, the ink storage unit is removable from the carriage, and the first portion and the second portion are located above the supply port.
