Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medium processing apparatuses face issues with liquid adhering to crimping teeth, leading to rust and reduced functionality, particularly in crimp binding processes without metal staples.
Innovation Solution
A medium processing apparatus with a liquid applier and post-processing device that includes a control system to manage liquid application and binding processes, featuring a rust adhesion prevention mode to minimize liquid contact with crimping teeth, and a separation assembly to remove adhering moisture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If liquid application is performed on medium bundle before crimp binding, then binding strength is improved, but liquid adheres to crimping teeth causing rust
Solution Approach 1:
The patent extracts the harmful liquid from the crimping teeth using a separate extraction mechanism. A brush or cloth is introduced to remove liquid adhering to the crimping teeth after the binding process, preventing rust while maintaining the binding strength benefits of liquid application.
Solution Approach 2:
The patent introduces an intermediary cleaning mechanism between the liquid application and crimp binding processes. This intermediary component (brush or cloth assembly) serves as a mediator to remove residual liquid from crimping teeth, allowing liquid application to enhance binding strength without causing rust.
2Object-affected harmful factors
If crimp binding is performed without liquid application, then rust on crimping teeth is prevented, but binding strength is reduced
Solution Approach 1:
The patent applies liquid to the medium bundle before crimp binding as a preliminary action. This preliminary liquid application enhances binding strength, and subsequent cleaning actions remove residual liquid from crimping teeth to prevent rust.
Solution Approach 2:
The cleaning mechanism is designed to automatically remove liquid from crimping teeth during or after the binding process without requiring manual intervention. The brush or cloth assembly is actuated by the existing driving mechanism, enabling self-service cleaning that prevents rust while maintaining binding strength.
3Ease of operation
If sheet separation assembly is provided in crimper, then sheet sticking is prevented, but liquid adhering to crimping teeth remains causing rust
Solution Approach 1:
The patent merges the sheet separation function with the liquid removal function by integrating a brush or cloth assembly into the existing crimp binding mechanism. This combined assembly performs both sheet separation and liquid removal from crimping teeth, preventing rust while maintaining ease of operation.
Solution Approach 2:
The cleaning component (brush or cloth) is designed to serve multiple functions: it removes liquid from crimping teeth to prevent rust, and assists in sheet separation. This multi-functional approach addresses both problems simultaneously without adding excessive complexity to the system.

AI summary
A medium processing apparatus includes a liquid applier, a post-processing device, and circuitry. The liquid applier performs liquid application on a medium. The post-processing device performs a binding process on a media bundle including the medium subjected to the liquid application by the liquid applier, or a medium not subjected to the liquid application. The circuitry is to control operations of the liquid applier and the post-processing device according to operation modes. The operation modes of the post-processing device include a first mode to perform the binding process on the media bundle including the medium on which the liquid application is performed, and a second mode to perform the binding process on the medium on which the liquid application is not performed.
