Automatic Lens Mounting Mechanism for Camera Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional DSLR cameras require manual operation to attach and detach lenses, which can be cumbersome and time-consuming, especially when frequently changing lenses.
Innovation Solution
An automatic lens connection system that detects lens insertion and automatically screws the lens into place using a mount with a lens detector, driver, and mount connector, allowing for quick and easy lens changes without manual operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation is used to attach and detach lenses, then the connection can be securely made, but the process becomes cumbersome and time-consuming
Solution Approach 1:
The lens attachment system performs the screwing operation automatically without requiring manual operation. The drive unit detects lens insertion and autonomously drives the mount connector to screw the lens into the mount, making the system serve itself rather than requiring user intervention for the fastening process.
Solution Approach 2:
The manual mechanical operation of screwing the lens by hand is replaced with an automated drive unit that uses a drive screw and mount connector mechanism. This substitution transforms the purely manual mechanical process into an automated electromechanical system, eliminating the need for manual manipulation while maintaining secure connection.
2Productivity
If automatic lens connection is implemented, then lens changing speed is improved, but the device complexity increases
Solution Approach 1:
The detection function and drive function are merged into an integrated mount structure. The drive unit combines the drive screw, mount connector, and detection capability in a single compact assembly that is built into the mount, rather than being separate components. This merging reduces overall system complexity while achieving automatic lens connection.
Solution Approach 2:
The mount connector serves multiple functions: it acts as both the detection target for lens insertion and the mechanical connector for securing the lens. The drive screw simultaneously provides both the driving force for attachment and the securing mechanism. This multi-functionality reduces the number of separate components needed, thereby reducing device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables rapid and secure attachment and detachment of lenses, improving user convenience and efficiency by automating the lens mounting process while ensuring a tight and safe connection.
Implementation Method 1
a lens detector for detecting insertion of the lens module insertion part into the mount
Implementation Method 2
a driver for driving the mount connector when the lens detector detects the insertion of the lens module insertion part
Implementation Method 3
a screw element having a screw thread that is disposed on an inner surface of the connection gear and combined with the lens module insertion part
Implementation Method 4
The mount connector may further include a plurality of bearings, which are interposed between the mount connector and the mount and between the mount connector and the mount support. The bearings may be a plurality of ball bearings

AI summary
An automatic-lens-connection-type camera system, which detects insertion of a lens unit into a mount part and automatically screws a mount connector to connect the lens unit with the mount part, and a method for controlling the camera system. The camera system includes a body, a lens module mounted to be attachable to and detachable from the body, a lens module insertion part mounted on a surface of the lens module that faces the body, and a mount part for detecting insertion of the lens module into the body to mount the lens module insertion part on the body.
