Scanner Image Alignment Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional scanning devices require internal adjustments of guide rods to be made during manufacturing, making post-factory image scanning adjustments inconvenient and requiring housing removal, which complicates maintenance.
Innovation Solution
An image alignment adjustment mechanism with a housing and adjustment tool that allows external adjustment of the scanning module, featuring a guiding structure with a fixed and adjustable guide rod, and an adjustment tool with a handle and engagement portion for precise adjustments without exposing the adjustment portion externally.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the adjustment portion is exposed externally for easy adjustment, then ease of operation is improved, but reliability deteriorates due to risk of inadvertent touching
Solution Approach 1:
The adjustment portion is nested inside the adjustment hole, allowing it to be accessed and adjusted through the adjustment hole without being fully exposed externally. This nesting approach enables easy adjustment while preventing inadvertent touching during normal operation.
Solution Approach 2:
The adjustment hole serves as an intermediary interface between the external environment and the adjustment portion. It allows users to access and adjust the scanning module when needed, while simultaneously protecting the adjustment portion from accidental contact during normal scanner operation.
2Ease of repair
If the adjustment device is accessible from outside the housing, then ease of repair is improved, but device complexity increases due to additional structural components
Solution Approach 1:
The housing is segmented with a specific adjustment hole created in the housing wall, separating the adjustment function from the main housing structure. This allows the adjustment device to be accessed independently without requiring disassembly of the entire housing, simplifying maintenance while adding minimal structural complexity.
Solution Approach 2:
The adjustment portion is extracted from the internal housing structure and made accessible through an opening in the housing. This extraction allows maintenance personnel to access and adjust the scanning module from outside the housing without removing the entire housing assembly.
