Copying Machine Original Cover Integrated Drive Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic original cover operators for copying machines are undesirable due to exposed driving parts, which complicate maintenance and design, and do not address the issue of appearance and operational complexity.
Innovation Solution
An automatic original cover operator design where the driving part is integrated with the original cover, allowing it to rotate independently, eliminating the need for protrusion on the main body and simplifying maintenance by being removable as a unit, with a rotation control mechanism using a combination of springs and an electromagnetic clutch for efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the driving part is mounted on the main body side, then the original cover can be automatically opened and closed, but the driving part protrudes on the main body side when the original cover is opened, resulting in undesirable appearance
Solution Approach 1:
The driving part is segmented from the main body and mounted on the original cover instead. The driving part includes a drive motor and reduction mechanism that are integrated into the original cover assembly, allowing the original cover to be removed as a unit without the driving part protruding on the main body.
Solution Approach 2:
The driving part is repositioned from a three-dimensional protrusion on the main body to a integrated component within the original cover assembly. This dimensional reorganization allows the driving mechanism to be concealed within the original cover's structure rather than protruding outward.
2Ease of operation
If the driving part is mounted on the main body, then automatic opening and closing is achieved, but maintenance requires additional steps and is complicated since the driving part must be removed from the main body when the original cover needs to be removed
Solution Approach 1:
The driving part is merged with the original cover into a single integrated assembly. The drive motor, reduction mechanism, and original cover form one unit that can be removed and installed together, eliminating the need for separate maintenance operations and simplifying repair procedures.
3Ease of manufacture
If the driving part is mechanically independent from the main body and mounted on the mounting member, then design changes on the main body are avoided, but the driving part remains exposed on the main body when the original cover is opened
Solution Approach 1:
The driving part is nested within the original cover assembly rather than being exposed on the main body. The drive motor and reduction mechanism are positioned inside the original cover's structure, with the original cover acting as a protective enclosure that conceals the driving mechanism while maintaining mechanical independence from the main body.

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 provides a sleeker appearance, simplified maintenance, and reduced operational complexity by integrating the driving mechanism within the original cover, enhancing usability and reducing the need for design changes to the main body.

AI summary
An automatic original cover operator of a copying machine, includes a hinge part and a driving part. The hinge part includes a mounting member attached to the main body of the copying machine, a supporting member rotatably mounted on the mounting member via a main shaft, a lifting member rotatably mounted on side plates of the supporting member via a drive shaft, a part for controlling rotation of the hinge part, the part for controlling rotation serving to urge the supporting member in an opening direction of the original cover and the lifting member to overlap the supporting member, and a rotation controlling mechanism for the lifting member. The driving part includes a drive case, a drive motor mounted in the drive case, and a reduction mechanism mounted in the drive case for transmitting a rotation drive force from the drive motor to the main shaft.
