Liquid Discharge Head Attachment Inclination Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid discharge apparatuses face issues with component damage and deformation due to inclination of the head attachment during operation failures, leading to collisions with lifts, which can result in damage to the liquid discharge head and other components.
Innovation Solution
Incorporation of contact members on the side faces of the head attachment that contact the lift when the head attachment is inclined, preventing further movement and potential collisions, or the use of elastic members that deform to stop the lifting operation when the head attachment is inclined.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the lift continues to move the head attachment during operation failure, then the lifting operation can be completed, but the head attachment may collide with the lift and cause component damage
Solution Approach 1:
The contact member is positioned to preemptively contact the lift before the head attachment can collide with it during inclination. This preliminary contact stops the lifting operation in advance, preventing the harmful collision while allowing the lifting operation to be completed under normal conditions.
2Ease of operation
If the head attachment is allowed to move freely during inclination, then the lifting operation can proceed, but components may deform or break due to collision
Solution Approach 1:
The contact member acts as an intermediary element between the head attachment and the lift. During inclination, the contact member first contacts the lift, mediating the interaction and stopping the lifting operation before the head attachment can collide with the lift, thus protecting components from damage.
3Reliability
If a contact member is added to prevent collision, then component damage is prevented, but the device complexity increases
Solution Approach 1:
The contact member is designed as a simple, inexpensive component that can be easily installed on the side of the head attachment. It serves its protective function during inclination and can be replaced if damaged, providing reliable protection without significantly increasing device complexity or cost.

Function Achieved in This Case
Prevents damage and deformation of components by stopping the lifting operation when the head attachment is inclined, enhancing the reliability of the liquid discharge apparatus by avoiding collisions with the lift and other components.
Implementation Method 1
The elastic member is elastically deformable in response to an inclination of the head attachment with respect to the plane

AI summary
A liquid discharge apparatus includes a liquid discharge head, a lift, and a contact member. The liquid discharge head discharges a liquid in a discharge direction. The liquid discharge head is attached onto the head attachment. The lift moves the head attachment back and forth in the discharge direction and keeps an orientation of the head attachment in a plane orthogonal to the discharge direction. The contact member is disposed on a side face of the head attachment. The contact member faces the lift and has a space with the lift in a width direction orthogonal to the discharge direction. The contact member is contactable the lift in response to an inclination of the head attachment with respect to the plane.
