Lens Barrel Detachable Frame for Maintenance Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lens barrels require re-adjustment of lens position or tilt angle after disassembly for maintenance, such as dust removal, which is inconvenient and time-consuming.
Innovation Solution
A lens barrel design featuring a detachable lens frame attached to an adjustable lens adjusting frame, allowing the position or tilt angle of the lens to be maintained during disassembly and assembly, using a configuration with adjustable pins and screws to ensure precise alignment and adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the lens frame is made detachable from the lens adjusting frame, then maintenance becomes easier, but the lens position or tilt angle may change during disassembly and assembly
Solution Approach 1:
The lens frame is pre-adjusted to the correct position and tilt angle before detachment. Adjustment marks or reference features are established in advance, allowing the lens to be reattached at the same position without requiring re-adjustment, thus maintaining precision while enabling easy maintenance
Solution Approach 2:
A positioning mechanism or reference feature acts as an intermediary between the lens frame and lens adjusting frame. This intermediary ensures that when the lens frame is reattached, it automatically returns to the correct position and orientation, preventing precision loss during maintenance cycles
2Object-generated harmful factors
If the lens barrel is disassembled for maintenance, then dust removal is possible, but time is lost due to required re-adjustment
Solution Approach 1:
The lens frame is pre-adjusted and secured with reference marks before detachment. This preliminary action ensures that when the lens is reattached after dust removal, no re-adjustment is needed, eliminating time loss while maintaining the ability to perform maintenance
Solution Approach 2:
The lens frame is designed with self-positioning features that automatically guide it back to the correct position during reattachment. This self-service mechanism eliminates the need for manual re-adjustment, saving time while allowing routine maintenance

AI summary
A lens barrel includes: a lens frame including at least one lens; a lens adjusting frame to which the lens frame is attached; and a fixed frame to which the lens adjusting frame is attached. The lens adjusting frame is attached to the fixed frame such that a position or a tilt angle of the lens adjusting frame is adjustable. The lens frame is attached to the lens adjusting frame such that the lens frame is detachable from the lens adjusting frame.
