External Optical Axis Adjustment Mechanism for Camera Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical axis adjusting mechanisms are inconvenient for installation and adjustment, as the adjusting devices are often located inside the imaging unit housing, requiring disassembly and reinstallation to correct axis direction errors.
Innovation Solution
An optical axis adjusting mechanism with a first and second adjusting plate, connected to a mounting bracket and imaging unit housing respectively, featuring rotatable axes outside the housing, along with a first and second rotation shaft, screws, pressure springs, and a jackscrew, allowing for convenient adjustment of the optical axis direction without disassembling the camera.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the adjusting device is located inside the imaging unit housing, then the structure is compact, but the adjustment becomes inconvenient requiring disassembly and reinstallation
Solution Approach 1:
The adjusting device is extracted from the imaging unit housing and mounted on the external mounting bracket. This allows the adjusting plates to be positioned outside the housing, enabling direct access for adjustment operations without requiring disassembly of the camera assembly.
Solution Approach 2:
An external mounting bracket is introduced as an intermediary structure between the camera and the adjusting mechanism. This mediator allows the adjusting device to be mounted externally while maintaining a stable connection, solving both the compactness and accessibility requirements.
2Ease of manufacture
If the adjusting device is installed inside the imaging unit housing, then the structure is integrated, but the optical axis adjustment requires taking out and reassembling the camera
Solution Approach 1:
The adjusting mechanism is segmented into independent components (mounting bracket, adjusting plates, rotation shafts) that can be assembled externally. This segmentation allows the adjustment function to be separated from the main camera assembly, enabling quick adjustments without full disassembly.
Solution Approach 2:
The mounting bracket and adjusting mechanism are pre-assembled as a separate unit before being integrated with the camera. This preliminary assembly allows the adjustment mechanism to be ready for use without requiring time-consuming on-site assembly of all components.
3Ease of operation
If the adjusting plates are located outside the imaging unit housing, then the adjustment is convenient and accessible, but the structure becomes more complex
Solution Approach 1:
The mounting bracket serves multiple functions: it provides external mounting for the adjusting mechanism, maintains structural support, and enables accessible adjustment operations. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in structural complexity.
