Liquid Ejecting Apparatus Adjustment Member Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing liquid ejecting apparatuses require increased space and longer manufacturing processes due to the need for adjustment members and fastening members that are not covered by the liquid container, leading to potential misalignment and increased complexity.
Innovation Solution
A method of manufacturing a liquid ejecting apparatus with a container holder that allows for the mounting of two liquid containers, where the adjustment member is positioned under the first container, enabling adjustments without the first container being mounted, thus reducing the number of attachment and detachment steps and minimizing the impact of container attachment and detachment forces on the adjustment mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the adjustment member is disposed at a position not covered by the liquid container, then the adjustment member can be accessed for alignment adjustment, but the size of the carriage and ejection mechanism is increased
Solution Approach 1:
The liquid container is designed to be movable between a mounted state and a detached state. When detached, the container allows access to the adjustment member; when mounted, it provides coverage and protection. This dynamic state change enables the system to optimize for different operational requirements without permanently increasing size.
Solution Approach 2:
The adjustment member is positioned in a spatial arrangement where it can be accessed from a direction not blocked by the liquid container when detached. The container holder structure is designed with multi-dimensional positioning capability, allowing the adjustment member to be reached from the side or rear when the container is removed, rather than requiring increased front-to-back depth.
2Manufacturing precision
If the adjustment member is disposed at a position not covered by the liquid container, then alignment adjustment can be performed, but the number of processes of attaching and detaching liquid storage member increases
Solution Approach 1:
The liquid container is detached in advance before alignment adjustment is performed. This preliminary detachment ensures that the adjustment member is accessible and not blocked by the container, allowing the alignment process to be completed in a single operation without requiring subsequent reattachment or readjustment.
Solution Approach 2:
The liquid container holder structure is designed to facilitate easy detachment and reattachment of the liquid container without requiring complex tools or procedures. The self-contained design allows the container to be quickly removed for adjustment and reinstalled afterward, minimizing the time loss from multiple attachment/detachment cycles.
3Manufacturing precision
If the adjustment member is disposed at a position not covered by the liquid container, then adjustment can be performed, but the position of the ejection mechanism shifts due to attachment and detachment
Solution Approach 1:
The liquid container is detached before alignment adjustment to prevent any potential shift during the adjustment process. By performing adjustment with the container removed, the system avoids the risk of the ejection mechanism position changing due to the container's attachment or detachment forces, thereby maintaining position stability.
Solution Approach 2:
The liquid container holder structure serves as an intermediary that provides a stable mounting base for the ejection mechanism. This holder structure is designed to maintain the ejection mechanism's position stable during adjustment operations, acting as a reference frame that prevents shifts even when the liquid container is detached or reattached.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach reduces the manufacturing time, enhances adjustment accuracy by using a second container with lower brightness for inspection, and allows for downsizing of the container holding member, while maintaining alignment precision and reducing external forces on the adjustment member.
