Camera Adapter Tripod Mount Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When using an adapter to mount an interchangeable lens with a long barrel length or heavy weight on a camera, the presence of a tripod-mounting portion on the adapter can cause inconvenience, particularly due to space constraints and potential interference with the camera body and lens.
Innovation Solution
The adapter design includes a first housing portion for attaching to the camera body and a second housing portion for attaching the interchangeable lens, with a tripod-mounting seat positioned internally relative to the lens's mounting seat, allowing for tripod attachment without interfering with the camera or lens, and featuring a movable member and driving apparatus to control the diaphragm-driving member of the lens.

Engineering Contradiction Analysis
1Ease of operation
If a tripod-mounting portion is provided on the adapter, then convenience of tripod mounting is improved, but space constraints and potential interference with camera body and lens occur
Solution Approach 1:
The patent positions the adapter's tripod-mounting portion in a different radial dimension relative to the lens's mounting portion. Specifically, the adapter's mounting portion is arranged further in the radial direction toward the camera body side compared to the lens's mounting portion, effectively using spatial dimensionality to avoid interference while maintaining both tripod mounting capabilities.
2Ease of operation
If a tripod-mounting portion is provided on the adapter, then tripod mounting capability is improved, but interference with camera body and lens occurs
Solution Approach 1:
The patent resolves the interference issue by arranging the adapter's tripod-mounting portion in a different radial position than the lens's mounting portion. The adapter's mounting portion is positioned further toward the camera body, creating radial separation that prevents physical interference between the adapter's mounting structure and the lens assembly.
Solution Approach 2:
The patent separates the tripod mounting function into distinct portions: the adapter includes its own tripod-mounting portion, while the lens includes its separate mounting portion. This segmentation allows both functions to coexist without interference by assigning different spatial locations to each mounting function.

AI summary
An adapter includes a first housing member that includes a first mount portion to which a camera body can be attached and detached and a second mount portion to which an interchangeable lens can be attached and detached, a second housing member that is integrally formed with the first housing member and includes a screw-receiving part, which can be attached to and detached from a tripod, in a side opposite to the first housing member, a driven member, and an actuator of a drive system for driving the driven member. The screw-receiving part is arranged in the vicinity of a center of an end of the second housing member, and at least a portion of the actuator is arranged in the periphery of the screw-receiving part in the second housing member.
