Mounting Device for Printhead Assembly with Interconnect Latching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Printing devices with 'on-axis' printhead assemblies face limitations in printing composition capacity, requiring frequent replacements and increasing costs when converting to 'off-axis' designs, which add complexity and expense due to the need for redesigned carriages and latching assemblies.
Innovation Solution
A mounting device that integrates a separate printing composition supply and tube assembly, allowing for increased capacity without the need for costly redesigns, featuring a latching mechanism that ensures secure attachment and easy disengagement of the printhead assembly, enabling seamless transition between 'on-axis' and 'off-axis' configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If an 'on-axis' printhead assembly design is used, then the device structure is simple and manufacturing cost is low, but the printing composition capacity is limited and requires frequent replacements
Solution Approach 1:
The system is divided into separate functional modules: the printhead assembly remains on-axis and simple, while a separate off-axis printing composition supply system is introduced. This segmentation allows the printing composition capacity to be increased without redesigning the entire carriage structure, as the supply system operates independently from the printhead assembly.
Solution Approach 2:
A mounting device acts as an intermediary between the existing on-axis printhead assembly and the new off-axis printing composition supply. This mounting device enables the integration of the separate supply system without requiring direct modification of the printhead assembly or carriage structure, thus increasing capacity while maintaining structural simplicity.
2Quantity of substance
If an 'off-axis' printhead assembly design is implemented, then printing composition capacity is increased, but the carriage and latching assembly must be redesigned increasing cost and complexity
Solution Approach 1:
The printing composition supply system is segmented from the printhead assembly, allowing the supply to be positioned off-axis without requiring changes to the carriage or latching assembly. The mounting device provides a simple interface that enables this separation, avoiding costly redesigns of existing components.
Solution Approach 2:
The mounting device is designed to be universally compatible with existing on-axis printhead assemblies while accommodating off-axis printing composition supplies. This multi-functional design allows the same mounting device to work with both configurations, eliminating the need for specialized redesigned carriages and reducing manufacturing costs.
3Quantity of substance
If an 'off-axis' printing composition supply is added to an existing printing device, then printing composition capacity is increased, but the latching assembly and carriage must be redesigned
Solution Approach 1:
The printing composition supply is extracted from the traditional on-axis integration and positioned as a separate off-axis component. The mounting device provides a simple attachment mechanism that does not require complex latching assembly modifications, as the supply can be independently mounted and secured without interfering with the existing carriage latching mechanism.
4Productivity
If frequent printhead assembly replacements are required due to limited capacity, then device simplicity is maintained, but user time is consumed and productivity decreases
Solution Approach 1:
The printing composition supply is positioned and secured in advance using the mounting device, allowing users to refill or replace the supply without removing the entire printhead assembly. This preliminary preparation enables continuous printing operations by allowing quick replacement of only the composition supply, minimizing downtime and maintaining productivity.

AI summary
Examples of a mounting device and method are disclosed herein. An example of the mounting device includes a carriage to hold a printhead assembly and an interconnect assembly to supply printing composition to the printhead assembly. The mounting device also includes a first latching assembly having an engaged condition to lock the interconnect assembly to a manifold of the printhead assembly and a disengaged condition to unlock the interconnect assembly from the manifold of the printhead assembly. The mounting device additionally includes a second latching assembly having an engaged condition to lock the printhead assembly to the carriage and a disengaged condition to unlock the printhead assembly from the carriage. In this example of the mounting device, the second latching assembly cannot be moved from the engaged condition to the disengaged condition unless the fast latching assembly is in the disengaged condition.
