Optical Scanning Apparatus Dust-Proof Transparent Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical scanning apparatuses face issues with dust ingress during the cleaning or replacement of transparent members, leading to performance deterioration and image quality issues due to dust accumulation on optical elements.
Innovation Solution
The apparatus incorporates a deflection unit, a casing with an aperture, a first light transmission member for dust-proofing, and a detachable second light transmission member to prevent dust entry during maintenance, ensuring the optical elements remain clean and functional.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the transparent member is adhesively fixed to the aperture portion, then the dust-proofing effect is improved, but the ease of cleaning and replacement deteriorates
Solution Approach 1:
The transparent member is divided into two separate components: a first transparent member that is adhesively fixed to the aperture portion for dust-proofing, and a second transparent member that is detachably mounted for easy cleaning and replacement. This segmentation allows each component to serve its specific function optimally without compromising the other.
2Ease of repair
If the transparent member is removed for cleaning, then the ease of cleaning is improved, but the dust entry into casing increases
Solution Approach 1:
By separating the transparent member into two detachable components, the second transparent member can be removed for cleaning while the first transparent member remains in place to maintain the dust-proof seal. This eliminates the need to remove the entire assembly, thus preventing dust entry during maintenance.
Solution Approach 2:
The first transparent member acts as an intermediary dust-proof barrier that remains installed in the casing, while the second transparent member serves as a removable cleaning target. This intermediary structure allows maintenance operations without compromising the dust-proof integrity of the system.
3Device complexity
If a single transparent member is used, then the device complexity is reduced, but the reliability of dust-proofing and maintainability deteriorates
Solution Approach 1:
The transparent member is segmented into two functional components with distinct roles: the first transparent member provides permanent dust-proofing through adhesive fixation, while the second transparent member provides maintainability through detachable mounting. This segmentation increases reliability by allowing selective maintenance without compromising the dust-proof seal.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively suppresses dust entry into the casing during cleaning or replacement, maintaining image quality and preventing dust accumulation on optical elements, thus ensuring consistent performance.
Implementation Method 1
a first light transmission member provided on the aperture for dust-proofing an interior of the casing, which is configured to transmit the light beam
Implementation Method 2
a support member configured to support a second light transmission member for transmitting a light beam that has been transmitted through the first light transmission member
