Light Scanning Device Cleaner With Recessed Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light scanning devices face challenges in maintaining high-quality image formation due to contamination from toner particles and dust, particularly with spherical toner, which is difficult to clean and often re-contaminates transparent covering members, leading to deteriorated electrostatic images and reduced laser light emitting performance over time.
Innovation Solution
A light scanning device equipped with a detachable cleaner featuring an elastic cleaning member and a recessed portion to prevent dust and toner particles from re-adhering to the transparent covering member, ensuring effective cleaning and maintaining the device's performance over a long period.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a transparent covering member is provided to prevent dust entry, then dust protection is improved, but contamination from toner particles and dust occurs leading to deteriorated image quality
Solution Approach 1:
The cleaning blade is positioned to contact and clean the transparent covering member before toner particles can accumulate and cause contamination. This preliminary cleaning action prevents toner adhesion to the covering member, maintaining both dust protection and image quality without requiring the covering member to be removed or replaced
2Manufacturing precision
If spherical toner is used for high quality images, then image quality is improved, but cleaning property deteriorates causing increased residual toner particles
Solution Approach 1:
The cleaning blade acts as an intermediary between the spherical toner particles and the transparent covering member. The blade's specific structure and material properties enable it to effectively remove spherical toner particles that would otherwise be difficult to clean, allowing high image quality to be maintained without compromising cleaning effectiveness
3Object-affected harmful factors
If a cleaning mechanism is provided to remove dust, then dust removal is improved, but complex structures and frequent maintenance are required
Solution Approach 1:
The cleaning blade is designed to automatically clean the transparent covering member during the normal operation of the light scanning device. The blade is positioned to contact the covering member as it moves, enabling continuous self-cleaning without requiring separate cleaning mechanisms, frequent maintenance interventions, or complex structural additions
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents re-contamination of the transparent covering member, ensuring consistent high-quality image formation and extended maintenance of the light scanning device's performance, even with spherical toner, by securely removing dust and toner particles during user-friendly cleaning operations.
Implementation Method 1
a cleaner which is detachably attached to the light scanning device and which has an elastic cleaning member on one side of a body thereof for cleaning the surface of the transparent covering member
