Ink Accommodation Device Finger-Hooking Cap Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in operability when injecting sublimation transfer ink from a bottle into an ink accommodation device due to the need to grip a cap, especially when wearing gloves, as the cap is difficult to handle.
Innovation Solution
An ink accommodation device with an inner cover that has a cap capable of moving between closing and opening positions, featuring a finger-hooking portion that allows the cap to be inserted and pulled out in the opening direction, eliminating the need for users to grip the cap during ink injection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cap is used to seal the injection port, then the injection port is sealed, but the user cannot easily open it when wearing a glove
Solution Approach 1:
The inner cover acts as an intermediary component between the user and the cap. By pressing the inner cover, the user indirectly opens the cap without needing to directly grip it. This mediator approach allows users wearing gloves to operate the device easily while maintaining the cap's sealing function.
Solution Approach 2:
The sealing function is divided into two independent components: the cap that provides the seal and the inner cover that provides the opening mechanism. This segmentation allows the cap to maintain its sealing reliability while the inner cover handles the ease of operation, resolving the contradiction between these two requirements.
2Ease of operation
If the cap is designed to be gripped and removed, then the injection port can be opened, but it becomes difficult to operate when wearing a glove
Solution Approach 1:
The inner cover serves as a mediator that translates user pressure into cap opening action. Users press the inner cover with their finger or palm (even through a glove), and this force is transmitted to open the cap. This maintains ease of operation while the cap itself retains its sealing function when closed.
Solution Approach 2:
The cap is designed to open automatically when the inner cover is pressed, without requiring the user to manually grip and remove the cap. The system serves itself by converting the pressing motion on the inner cover into cap opening action, making operation easy even when wearing gloves.

AI summary
An ink accommodation body capable of accommodating a sublimation transfer ink injected, via an injection port from, a bottle accommodating the sublimation transfer ink, and a first cover having a cap capable of closing the injection port, and movable between a closing position at which the cap closes the injection port and an opening position at which the cap opens the injection port, are included, and the cap can be inserted into and pulled out of the injection port in an opening direction of the injection port when the first cover moves between the closing position and the opening position, and the first cover has a finger-hooking portion enabling insertion and pulling of the cap with a finger.
