Printhead Ink Connector Rotation for Accurate Head Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing printing apparatuses face challenges in maintaining accurate connection between the printhead and the connecting member due to loose or tight fittings, which can lead to posture changes and reduced connection accuracy.
Innovation Solution
A printing apparatus with a support member, connecting member, rotation member, and biasing portion that allows for a changeable posture of the connecting member, ensuring precise alignment and connection between the ink introduction portion and the connecting portion through a rotatable mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the fitting between the joint member and the groove is tight, then the connection strength is improved, but the movement smoothness deteriorates
Solution Approach 1:
The joint member is designed to rotate relative to the carriage cover, transitioning from a static fixed connection to a dynamic adjustable connection. This allows the system to adapt between tight fitting for strength and loose fitting for smooth movement through rotational degrees of freedom.
Solution Approach 2:
The fitting parameters between the joint member and groove are optimized to achieve a balance - not too tight to prevent rotation, not too loose to maintain connection strength. The groove dimensions and joint member geometry are specifically designed to allow controlled movement while maintaining adequate connection.
2Ease of operation
If the fitting between the joint member and the groove is loosened, then the movement smoothness is improved, but the connection accuracy deteriorates
Solution Approach 1:
The groove acts as an intermediary guide structure that constrains the joint member's movement path. By providing guided rotation through the groove geometry, the system achieves smooth movement while maintaining connection accuracy through the groove's positioning function.
Solution Approach 2:
The joint member rotates dynamically within the groove, allowing smooth movement while the groove's geometric constraints maintain positioning accuracy. The rotational degree of freedom enables smooth operation without sacrificing connection precision.
3Ease of operation
If the joint member is loosely fitted in the groove, then the movement smoothness is improved, but the posture stability deteriorates
Solution Approach 1:
The joint member is designed with rotational capability relative to the carriage cover, allowing it to dynamically adjust its posture while moving. This dynamic design enables smooth movement through controlled rotation while maintaining adequate posture stability during operation.
Solution Approach 2:
The groove serves as a guiding intermediary that constrains the joint member's rotational path. This guidance mechanism enables smooth movement while preventing unintended posture changes, thereby maintaining posture stability during operation.
4Stability of the object's composition
If the joint member is tightly fitted in the groove, then the posture stability is improved, but the movement smoothness deteriorates
Solution Approach 1:
The joint member is designed to rotate relative to the carriage cover, transitioning from a static tightly-fixed connection to a dynamic adjustable connection. This allows the system to achieve both posture stability during operation and smooth movement during positioning through rotational degrees of freedom.
Solution Approach 2:
The fitting parameters between the joint member and groove are optimized to allow controlled rotation - not so tight as to prevent movement, not so loose as to compromise posture stability. The groove dimensions and joint member geometry are specifically designed to balance these requirements.

AI summary
A printing apparatus includes a support member configured to support a printhead that performs printing by discharging ink to a print medium, a connecting member including a connecting portion connected to an ink introduction portion of the printhead and through which the ink introduction portion communicates with an ink supply passage via the connecting portion, a rotation member configured to hold the connecting member such that a posture of the connecting member is changeable, and configured to be supported by the support member to be rotatable between a connecting position at which the ink introduction portion and the connecting portion are connected and a connection releasing position at which the ink introduction portion and the connecting portion are not connected, and a biasing portion configured to bias the connecting member to a first posture with respect to the rotation member.
