Automated Cleaning Member Exchange for Viscous Fluid Printers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional printing apparatuses require manual exchange of cleaning members, which is labor-intensive and inefficient.
Innovation Solution
A printing apparatus with a cleaning section, a cleaning member moving section, and an exchange control section that enables automatic exchange of the cleaning member by moving it between a cleaning position and an exchange position, using a mechanism with an attachment member and a loading member to facilitate unloading and loading, and a support member to manage the exchange process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual exchange of cleaning member is performed, then operator control and flexibility are maintained, but operator workload increases and exchange efficiency decreases
Solution Approach 1:
The cleaning member moving section enables the system to automatically perform cleaning member exchange without operator intervention. The exchange control section coordinates the moving section to autonomously complete the entire exchange process, making the system self-servicing for this repetitive task.
Solution Approach 2:
The patent replaces the manual mechanical operation of cleaning member exchange with an automated mechanical system. The cleaning member moving section uses mechanical mechanisms (such as conveyors, grippers, or robotic arms) to automatically transport and install cleaning members, substituting human physical labor with automated mechanical action.
2Productivity
If cleaning member exchange is performed manually, then system simplicity is maintained, but operational efficiency and productivity are reduced
Solution Approach 1:
The cleaning member moving section is designed as a multi-functional module that can handle multiple cleaning members of different types. The exchange control section provides universal control capabilities that can manage various exchange scenarios, making the added complexity serve multiple purposes and justify the investment.
Solution Approach 2:
The cleaning member exchange function is segmented into distinct modular components: the cleaning member moving section for physical manipulation and the exchange control section for coordination. This segmentation allows the complexity to be distributed and managed independently, reducing the burden on any single component and facilitating easier maintenance and upgrades.
3Ease of operation
If automatic cleaning member exchange is implemented, then operator workload is reduced and productivity improves, but device complexity increases
Solution Approach 1:
The exchange control section serves as an intermediary between the automated moving section and the cleaning members. It translates high-level exchange commands into specific control signals for the moving section, abstracting the complexity away from the operator while maintaining ease of use through simple interface commands.
