Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming systems face challenges in maintaining the cleaning elements without wastefully consuming image forming materials, particularly when microparticles are applied to improve transferability on surfaces with roughness, such as embossed media.
Innovation Solution
An image forming system that includes a rotatable image carrying element, an image forming element using an external additive, a transfer element, a plate-shaped cleaning element, a maintenance element forming band-shaped maintenance images, a microparticle application element, and a control element that adjusts the maintenance image amount based on microparticle application state to optimize cleaning and transfer efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If microparticles are applied to the image carrying element to improve transferability on rough surfaces, then transfer efficiency is improved, but the cleaning element wears out faster and requires more frequent maintenance
Solution Approach 1:
The system performs preliminary maintenance by forming a maintenance image on the image carrying element before the cleaning element becomes contaminated. This maintenance image is transferred to the cleaning element, restoring its cleaning capability proactively before wear affects performance, thus extending the cleaning element's usable life while maintaining high transfer efficiency
Solution Approach 2:
The cleaning element maintains its own functionality by receiving maintenance images transferred from the image carrying element. The system enables the cleaning element to self-renew its surface properties through the transfer of maintenance images, reducing the need for external intervention and replacement
2Reliability
If maintenance images are continuously formed to maintain cleaning element performance, then cleaning reliability is improved, but consumption of image forming materials increases
Solution Approach 1:
Instead of continuous maintenance image formation, the system uses periodic maintenance triggered by detection of cleaning element contamination or wear. The control unit determines when maintenance is needed based on operational conditions, forming maintenance images only at appropriate intervals, thus reducing unnecessary consumption of image forming materials while maintaining cleaning performance
Solution Approach 2:
The system incorporates detection of the cleaning element's state and uses this feedback to control when maintenance images are formed. The control unit adjusts maintenance frequency and timing based on actual cleaning element condition and image forming activity, optimizing the balance between cleaning reliability and material consumption

Function Achieved in This Case
The system effectively reduces the consumption of image forming materials by controlling the maintenance image amount and improving transferability on rough surfaces, preventing cleaning failures and maintaining the integrity of the cleaning elements.
Implementation Method 1
a microparticle application element that regularly or irregularly applies a microparticle having lubricity to the image carrying element
Implementation Method 2
a cleaning element having a plate shape, the cleaning element being disposed so that a leading end comes into contact with the image carrying element while being inclined in a direction opposite to a rotation direction of the image carrying element to clean a residue remaining on the image carrying element
Implementation Method 3
a transfer element that transfers the image carried by the image carrying element to a medium
