Rotating Device Transmission Mechanism for Compact Drive Configuration
Solution Overview
Problem
Rotating devices become large and complex when multiple drive units are required to transmit drive forces in different directions to rotating bodies, leading to increased size and complexity in image forming apparatuses.
Innovation Solution
A rotating device with a transmission mechanism that outputs drive forces in both forward and reverse rotation directions to a first rotating body and a second rotating body, allowing the first rotating body to rotate in both directions while the second rotating body can rotate in forward and reverse directions, reducing the need for multiple drive units and simplifying the device's configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple drive units are used to transmit drive forces in different directions to rotating bodies, then the rotation control capability is improved, but the device size and complexity increase
Solution Approach 1:
The patent combines multiple drive units into a single drive unit that can output drive forces in both forward and reverse rotation directions. This merging reduces the number of separate drive units needed while maintaining the ability to control rotation in different directions, thereby reducing device size and complexity without sacrificing rotation control capability.
Solution Approach 2:
The single drive unit is designed to perform multiple functions by being capable of outputting drive forces in both forward and reverse rotation directions. This multi-functional design eliminates the need for separate drive units for different rotation directions, resolving the contradiction between versatility and device complexity.
2Adaptability or versatility
If multiple drive units are used to rotate rotating bodies in forward and reverse directions, then the rotation flexibility is improved, but the number of components increases
Solution Approach 1:
Multiple drive units are merged into a single drive unit that can provide drive forces for both forward and reverse rotation. This consolidation reduces the number of components while preserving rotation flexibility through the single unit's ability to operate in multiple directions.
Solution Approach 2:
The single drive unit is designed with universal capability to drive rotating bodies in both forward and reverse directions, eliminating the need for separate drive units and reducing the overall component count while maintaining rotation flexibility.
3Device complexity
If separate drive units are used for forward and reverse rotation, then the drive force transmission is simplified, but the device becomes larger
Solution Approach 1:
The patent merges separate drive units for forward and reverse rotation into a single drive unit. This combining reduces device volume while the transmission mechanism maintains simplified drive force transmission by efficiently directing power in the required direction.
Solution Approach 2:
The transmission mechanism dynamically adapts to transmit drive forces in different directions based on operational requirements. This dynamic capability allows a single drive unit to replace multiple static drive units, reducing device volume without compromising transmission simplicity.
