Exposure Apparatus Housing Vibration Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing exposure apparatuses in image forming systems experience bending in the gravity direction due to unsupported structure sections, leading to increased vibration and potential errors in imaging quality.
Innovation Solution
The exposure apparatus incorporates a substrate with light emitting elements extending in the longitudinal direction, a housing with a support section for both end portions, and a vibration suppressor with a weight attached to an intermediate portion, supported by the support section to reduce bending and vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a structure section having a weight is attached to the housing to reduce vibration, then vibration reduction is achieved, but the housing bends in the gravity direction due to the unsupported weight
Solution Approach 1:
A support section is introduced as an intermediary component between the structure section and the housing. This support section extends from the housing to support the structure section, thereby preventing the housing from bending under the weight of the structure section while still enabling vibration reduction through the attached weight.
2Device complexity
If the structure section is supported only by the housing, then the configuration is simple, but the housing bends under gravity affecting imaging precision
Solution Approach 1:
The support section serves as a mediator that distributes the gravitational load from the structure section, preventing direct transmission of bending forces to the housing. This maintains imaging precision while adding only minimal structural complexity.
3Productivity
If the housing is made longer to accommodate more light emitting elements, then light emission capacity increases, but the housing becomes more susceptible to bending and vibration
Solution Approach 1:
The structure section with its weight acts as a counterweight that reduces vibrations of the housing. By strategically positioning this weighted section and supporting it properly, the system counteracts the increased susceptibility to vibration that comes with a longer housing containing more light emitting elements.
Applied Scientific Principles
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 configuration effectively reduces bending and vibration of the housing in the gravity direction, enhancing the imaging quality by stabilizing the position of the vibration suppressor and maintaining the relative positional relationship with the housing.
Implementation Method 1
a structure section having a weight that is attached to an intermediate portion of the housing in the longitudinal direction and supported by the support section in the gravity direction

AI summary
An exposure apparatus includes: a substrate that extends in a longitudinal direction intersecting with a gravity direction and has light emitting elements emitting light toward a gravity direction; a housing that extends in the longitudinal direction, to which the substrate is attached; a support section that supports both end side portions of the housing in the longitudinal direction against gravity; and a structure section having a weight that is attached to an intermediate portion of the housing in the longitudinal direction and supported by the support section in the gravity direction.
