Elastic Coupling for Imaging Unit Drive Shaft Oscillation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image formation apparatuses face compatibility issues with single-body and double-body type imaging units, leading to color deviation due to differences in structure, which cannot be resolved without changing the imaging unit structures, and solutions like adding elastic parts or increasing rigidity increase costs.
Innovation Solution
The imaging unit is designed with a toner bottle and print unit coupled via an elastic member, allowing for compatibility between single-body and double-body types without the need for additional elastic parts in the main body, using a flexible drive transmission and positioning system to prevent color deviation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the toner bottle and print unit are rigidly fixed in a single-body type imaging unit, then the structure is simple and cost is reduced, but oscillation from the drive shaft is transmitted to the print unit causing color deviation
Solution Approach 1:
An elastic member is introduced as an intermediary between the toner bottle and print unit. This elastic member absorbs oscillations from the drive shaft before they can be transmitted to the print unit, preventing color deviation while maintaining the simple single-body structure
Solution Approach 2:
The coupling between toner bottle and print unit is changed from rigid to elastic by introducing an elastic member. This parameter change allows the system to absorb vibrations and oscillations, preventing color deviation without complicating the overall structure
2Manufacturing precision
If an elastic member is provided between the toner bottle and print unit in a double-body type imaging unit, then oscillation transmission is suppressed, but the structure becomes more complex and cost increases
Solution Approach 1:
The elastic member is designed to serve multiple functions: it absorbs oscillations to prevent color deviation, provides flexible coupling between the toner bottle and print unit, and enables compatibility between single-body and double-body type imaging units. This multi-functionality reduces the need for additional separate components
3Device complexity
If the attached part in the main body is designed for single-body type imaging units, then the structure is simple, but it cannot be commonly used with double-body type imaging units
Solution Approach 1:
The attached part in the main body is designed with universal compatibility to accommodate both single-body and double-body type imaging units. The elastic member in the imaging unit adapts to this universal interface, allowing the same attached part design to work with both types without modification

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design ensures compatibility and prevents color deviation by using an elastic member to couple the toner bottle and print unit, reducing the need for additional elastic parts and maintaining a simple structure, thus suppressing cost increases.
