Liquid Container Circuit Board and Fixation Structure Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid container designs for ink jet printing and similar applications face challenges in high-density arrangement due to the positioning of circuit boards and fixation structures, leading to gaps between containers and potential electrical connection failures, especially as container size increases and urging forces become stronger.
Innovation Solution
The design features a liquid container with a circuit board on one side surface and a container fixation structure on the opposite side, allowing for parallel arrangement without the need for additional fixation structures between containers, with a liquid supply port on the front end and positioning mechanisms to maintain precise electrical connections and prevent ink leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the circuit board and fixation structure are positioned on perpendicular surfaces of the container, then the electrical connection between the circuit board and apparatus terminal can be maintained, but the containers cannot be arranged in high density due to required gaps between adjacent containers
Solution Approach 1:
The invention repositions both the circuit board and the container fixation structure from perpendicular surfaces to the same surface (the front end surface) of the container. This dimensional reorganization allows containers to be arranged in parallel without requiring gaps for fixation structures on side surfaces, thereby achieving high-density arrangement while maintaining electrical connection reliability through the circuit board's position on the front end surface.
2Quantity of substance
If the container size is increased to accommodate larger liquid volumes, then the storage capacity is improved, but the urging force in the direction opposite to insertion direction becomes stronger making detachment and mounting more difficult
Solution Approach 1:
The container fixation structure is designed to engage with the apparatus fixation structure before the container is fully inserted, creating a preliminary mechanical linkage. This preliminary engagement guides the container into proper alignment and distributes the mounting force, reducing the opposing urging force experienced during insertion and detachment operations even for larger containers.
3Reliability
If the circuit board is positioned on the side surface of the container, then the electrical connection can be established, but the positioning precision between the contact point and apparatus terminal deteriorates leading to connection failures
Solution Approach 1:
The invention merges the positioning function with the electrical connection function by integrating the circuit board directly onto the front end surface of the container, which is the same surface that receives the apparatus fixation structure. This merging ensures that both the mechanical fixation and electrical contact points are precisely positioned relative to each other on the same surface, eliminating positioning errors that would occur with separate mounting locations.

AI summary
A liquid container that has a container body storing a liquid to be supplied to a liquid consuming apparatus and that is detachably mounted on a container mounting portion of the liquid consuming apparatus, wherein a liquid supply port for sending out the liquid to be supplied to the liquid consuming apparatus is formed on a front end surface in an insertion direction of the container body having a substantially rectangular shape, wherein a circuit board having a contact point with the liquid consuming apparatus is formed on one side surface perpendicular to one corresponding short side of the front end surface in the insertion direction, and wherein a container fixation structure for releasably regulating a movement of the container body in a direction opposite to the insertion direction thereof in cooperation with an apparatus fixation structure formed on the container mounting portion is formed on the other side surface perpendicular to the other corresponding short side of the front end surface in the insertion direction in a state where the container body is mounted on the container mounting portion against an urging force in the direction opposite to the insertion direction.
