Cleaning Holder Segmentation for Easy Guide Rail Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electro-photographic image forming apparatuses face challenges in maintaining the cleanliness of transmissive members, leading to potential contamination and reduced image quality due to the difficulty in easily replacing and detaching the cleaning members from guide rails.
Innovation Solution
The design incorporates a holding member that integrally holds cleaning members, with a moving unit and guide portions allowing for easy longitudinal movement and detachment of the cleaning holders from guide rails, enhancing the exchangeability and cleaning efficiency of the transmissive members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cleaning member is held by a cleaning holder that is fixed to a wire and moves along a guide rail, then the cleaning member can clean the transmissive member, but the cleaning holder becomes difficult to detach from the guide rail after long-term use
Solution Approach 1:
The cleaning holder is divided into a holder body and a detachable engaging portion. The engaging portion can be separated from the guide rail by moving it in the longitudinal direction, allowing easy detachment and replacement of the cleaning member without affecting the overall cleaning function.
Solution Approach 2:
The engaging portion is designed to transition between engaged and disengaged states. When moved in the longitudinal direction, it disengages from the guide rail, providing dynamic adaptability for both stable cleaning operation and easy replacement.
2Manufacturing precision
If the cleaning member is pressed against the transmissive member to remove foreign matters, then cleaning effectiveness is improved, but the cleaning member itself becomes contaminated over time
Solution Approach 1:
The cleaning member is designed to be periodically replaced. When contaminated, the entire cleaning holder with the cleaning member can be easily detached from the guide rail and replaced with a new one, ensuring continuous cleaning effectiveness without accumulating contamination.
Solution Approach 2:
The cleaning member is extracted as a replaceable component from the cleaning holder system. This allows the contaminated cleaning member to be removed and replaced independently, maintaining the cleanliness of the transmissive member while managing the contamination of the cleaning member.
3Stability of the object's composition
If the cleaning holder is engaged with the guide rail for stable movement, then cleaning stability is improved, but the detachment and replacement process becomes complex
Solution Approach 1:
The cleaning holder is segmented into a stable holder body that remains engaged with the guide rail during cleaning, and a detachable engaging portion that can be easily separated. This segmentation maintains stability during operation while simplifying the replacement process.
Solution Approach 2:
The engaging portion provides dynamic engagement and disengagement capability. It maintains stable connection during cleaning operations but can be easily detached by moving in the longitudinal direction, reducing the complexity of the overall detachment mechanism.
