Ink Bottle Valve and Restriction Member for Leakage Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ink bottles face issues with ink leakage when tilted or subjected to compressive forces, compromising convenience due to the lack of effective sealing mechanisms and air introduction methods.
Innovation Solution
The design incorporates a valve system in the guiding portion to control ink flow, a restriction member to prevent compression deformation, and a closing portion to manage air introduction, along with a nozzle member that breaks through a film for easy ink flow and air exchange, ensuring minimal leakage and efficient ink dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the bottle is tilted downward to facilitate ink flow, then ink dispensing is improved, but ink leaks from the outflow port
Solution Approach 1:
A valve member is introduced as an intermediary component between the ink container and the outflow port. This valve selectively opens and closes the flow passage based on the bottle's orientation, allowing ink to flow when the bottle is upright while preventing leakage when tilted. The valve acts as a mediator that responds to gravitational forces and user actions to control ink flow accordingly.
2Ease of operation
If the bottle is subjected to compressive forces to improve portability, then ease of carrying is improved, but the container deforms and causes ink leakage
Solution Approach 1:
A restriction member is pre-installed within the container to provide structural support and prevent deformation before compressive forces are applied during carrying. This restriction member acts as a cushioning element that maintains the container's shape and prevents the walls from collapsing or deforming under compression, thereby avoiding ink leakage while allowing the bottle to be portable.
3Reliability
If the container is made airtight to prevent leakage, then ink preservation is improved, but air cannot be introduced for ink flow
Solution Approach 1:
The valve member is designed to dynamically change the state of the flow passage between closed and open based on the bottle's orientation and user actions. When the bottle is upright, the valve opens to allow both ink flow and air introduction. When tilted or subjected to compression, the valve closes to maintain airtightness and prevent leakage. This dynamic behavior resolves the contradiction between maintaining airtightness and allowing air flow.
4Strength
If a cover is added to protect the container end, then protection against deformation is improved, but device complexity increases
Solution Approach 1:
The cover is merged with the existing bottle structure, specifically integrating with the cap assembly that already covers the outflow port. By combining the protective cover function with the existing cap structure, the design provides enhanced protection against deformation and damage without significantly increasing overall complexity. The cover works synergistically with the valve and restriction member to provide comprehensive protection.

AI summary
Convenience of an ink bottle and a bottle set is improved. An ink bottle includes: a container portion that contains ink; a guiding portion that is formed in one end portion of the container portion, and includes an outflow port from which the ink in the container portion flow out; and a cover that covers at least an end portion of the container portion on the opposite side of the guiding portion.
