Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses face challenges in effectively reducing noise generated by driving devices due to vibrations, as previous countermeasures are not universally effective across different types of apparatuses and mechanisms.
Innovation Solution
A driving device design featuring a holding part with a first member and a second member that are partially coupled, allowing vibrations to interfere and cancel out, with the grounding member contacting the more difficult-to-vibrate member to stabilize electrical grounding and reduce noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If vibration insulating members are used to reduce noise, then noise is reduced to some extent, but the solution is not universally effective across different types of image forming apparatuses and driving devices
Solution Approach 1:
The patent applies the principle of mechanical vibration by intentionally generating vibrations from a vibration generation unit that match the frequency of vibrations from the driving device. These controlled vibrations interfere with and cancel out the harmful vibrations, reducing noise. This approach is universally applicable to different types of image forming apparatuses regardless of their specific driving device configurations.
Solution Approach 2:
The patent introduces a vibration generation unit as an intermediary component that produces counter-vibrations to cancel harmful vibrations. This mediator approach allows the solution to work across different apparatus types without requiring modification of the original driving devices, providing universal applicability while effectively reducing noise.
2Object-affected harmful factors
If multiple countermeasures are implemented for different types of image forming apparatuses, then noise reduction effectiveness improves, but device complexity and number of parts increase
Solution Approach 1:
The vibration generation unit is designed as a universal component that can be applied to different types of image forming apparatuses without requiring apparatus-specific customization. The unit generates vibrations at frequencies that match various driving devices, providing effective noise reduction across multiple apparatus types while maintaining a simple, standardized structure that does not increase overall device complexity.
3Object-affected harmful factors
If vibration cancellation is achieved through complex multi-member coupling structures, then vibration reduction improves, but manufacturing cost and structural complexity increase
Solution Approach 1:
The patent segments the vibration control function into a separate, dedicated vibration generation unit rather than using complex multi-member coupling structures. This segmented approach simplifies manufacturing by allowing the vibration generation unit to be produced as a standardized component, reducing production costs while maintaining effective vibration cancellation through frequency-matched counter-vibrations.
