Optical Scanning Attachment Mechanism for Imaging Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical scanning devices face challenges in accurately adjusting the imaging distance and position due to component dimension errors and assembly issues, requiring separate position fixing members and dedicated tools, which are labor-intensive and time-consuming.
Innovation Solution
An attachment mechanism featuring a position fixing member with an erection plate, first, and second supporting plates that adjust the plane position and height of a fitted hole to align the optical scanning device, allowing for simultaneous adjustment of imaging distance and position using a single mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a position fixing member is used to adjust imaging distance and imaging position, then the optical scanning device can be positioned accurately, but multiple separate position fixing members and dedicated tools are required, increasing device complexity and adjustment time
Solution Approach 1:
The patent combines multiple position fixing members into a single integrated position fixing member that includes a first supporting plate with a first fitted hole for imaging distance adjustment and a second supporting plate with a second fitted hole for imaging position adjustment. This merging eliminates the need for multiple separate components and dedicated adjustment tools, reducing device complexity while maintaining positioning accuracy
Solution Approach 2:
The single position fixing member performs multiple functions: it adjusts both imaging distance and imaging position, and can accommodate different optical scanning devices through universal engagement with positioning bosses. This multi-functionality reduces the number of components needed and simplifies the adjustment process
2Measurement precision
If separate position fixing members are used for imaging distance and imaging position adjustment, then positioning accuracy can be achieved, but adjustment time increases due to the need to replace multiple components
Solution Approach 1:
By merging the first supporting plate and second supporting plate into a single position fixing member assembly, the patent enables simultaneous adjustment of both imaging distance and imaging position without requiring sequential replacement of multiple separate components, significantly reducing adjustment time
3Manufacturing precision
If dedicated tools and jigs are required for position adjustment, then precise positioning can be achieved, but ease of operation decreases due to the need for specialized equipment
Solution Approach 1:
The position fixing member is designed to be self-adjusting through its engagement with positioning bosses on the optical scanning device. The first and second fitted holes automatically align with the positioning bosses when the position fixing member is attached to the supporting base, eliminating the need for dedicated adjustment tools or jigs while maintaining positioning precision

AI summary
An attachment mechanism of an optical scanning device includes a frame body provided with a supporting base having engaging parts; and a position fixing member arranged between the optical scanning device and the supporting base to have an erection plate, a first supporting plate and a second supporting plate. The first or second supporting plate includes a fitted hole fitting with a positioning boss of the optical scanning device. The first and second supporting plates respectively include first engaged parts and second engaged parts. The position fixing member is attached to the supporting base by engaging one of the first engaged parts and one of the second engaged parts with the engaging parts. The position fixing member changes a plane position of the fitted hole by engaging positions of the engaging parts with the first and second engaged parts and changes a height of the fitted hole by inverting.
