Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-function office machines with automatic document feeders face issues with feeding thicker or harder data carriers due to inconsistent thicknesses, leading to paper jams and inefficient processing.
Innovation Solution
A transmission assembly with a body, first and second rollers, a flexible element, and a transmission element that adjusts to accommodate varying thicknesses by rotating in the same direction, ensuring smooth data carrier transfer through a data carrier transferring channel with additional rollers and a friction element for enhanced friction and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the feeding mechanism of the ADF is adjusted for processing general papers, then general papers can be fed smoothly, but thicker or harder data carriers cannot be fed properly due to inconsistent thicknesses
Solution Approach 1:
The patent employs a dynamic feeding mechanism where the lower roller is mounted on a movable guide rail that can adjust its position vertically. This allows the roller to adapt to different data carrier thicknesses by moving along the guide rail, maintaining proper contact pressure for both thin papers and thick cards without requiring manual mechanism adjustment.
Solution Approach 2:
The system changes the positional parameter of the lower roller along the guide rail to accommodate different data carrier thicknesses. By varying the vertical position of the roller, the mechanism optimizes the feeding parameters for each type of data carrier, enabling smooth feeding of both general papers and thicker cards.
2Adaptability or versatility
If the ADF feeding mechanism is designed for thick data carriers, then thicker cards can be fed, but general papers may experience feeding issues due to insufficient contact pressure
Solution Approach 1:
The movable lower roller on the guide rail provides dynamic adjustment capability, allowing the system to optimize contact pressure for different data carrier types. When processing thick cards, the roller position adjusts to provide adequate pressure, while for general papers, the roller moves to maintain appropriate contact without excessive force.
Solution Approach 2:
The guide rail mechanism serves multiple functions: it enables the lower roller to adapt to different data carrier thicknesses, maintains proper feeding pressure for various materials, and prevents paper jams across different carrier types. This single structural feature provides universal adaptability for both thin papers and thick cards.
3Reliability
If manual adjustment of the feeding mechanism is required for different data carrier types, then proper feeding can be achieved, but user operation becomes complicated and time-consuming
Solution Approach 1:
The system performs self-adjustment through the movable lower roller that automatically adapts to different data carrier thicknesses as they are loaded. The guide rail mechanism allows the roller to find its optimal position autonomously, eliminating the need for users to manually adjust the feeding mechanism for different carrier types.
Solution Approach 2:
The dynamic positioning of the lower roller along the guide rail enables automatic adaptation to different data carrier thicknesses. This dynamic adjustment occurs passively as data carriers are loaded, providing reliable feeding for various materials without requiring active user intervention or complex manual adjustments.
