Conductive Media Support Sections for Static-Free Sheet Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing medium discharge devices, static electricity accumulates on support sections due to repeated contact with media, causing alignment issues as the media is attracted to these sections, leading to degradation in stacking quality.
Innovation Solution
Incorporating conductive members into the support sections to dissipate static electricity, ensuring that the support sections are made of conductive materials or coated with conductive resins, and grounding these members to a static discharge section to effectively eliminate static charges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pair of support sections is used to support the medium, then the medium can be properly supported and discharged, but static electricity accumulates on the support sections causing degradation in medium alignment
Solution Approach 1:
The patent applies the grounding mechanism to convert the harmful static electricity accumulation into a beneficial state by providing a discharge path. The conductive member connected to ground potential allows static charge to be safely dissipated, transforming the harmful electrostatic attraction into a neutral state that preserves medium alignment quality.
Solution Approach 2:
The conductive member acts as an intermediary between the support section and ground. It provides a controlled path for static electricity to flow from the support section to ground, preventing direct accumulation on the support surfaces while maintaining the support function.
2Productivity
If repeated contact occurs between medium and support sections, then medium transport is enabled, but static electricity accumulates on the support sections
Solution Approach 1:
The patent extracts the harmful static electricity from the support section system by introducing a separate grounding path. The conductive member removes the accumulated charge from the support section, separating the useful support function from the harmful electrostatic effect.
Solution Approach 2:
The repeated contact that generates harmful static electricity is converted into a beneficial process by providing a grounding path. The same contact that causes charge accumulation now enables charge dissipation through the conductive member to ground, maintaining productivity while eliminating the harmful effect.
3Manufacturing precision
If the support sections are made conductive to discharge static electricity, then medium alignment is maintained, but device complexity increases
Solution Approach 1:
The conductive member serves multiple functions simultaneously: it provides structural support, enables static electricity discharge, and maintains medium alignment. By combining these functions into a single component, the patent avoids increasing overall device complexity while achieving the desired alignment precision.
Solution Approach 2:
The patent merges the support function and static electricity discharge function into a single integrated structure. The conductive member is incorporated directly into the support section, eliminating the need for separate components and reducing overall device complexity.
