Camera Lens Adapter Ring for Interchangeable Mounts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera lens mounts are limited in interchangeability, requiring users to purchase specific lenses for each camera type, and intermediate mounts offer only limited compatibility due to geometrical constraints, leading to restricted lens compatibility across different camera systems.
Innovation Solution
A camera lens assembly with an adapter ring system that allows for interchangeable connection of various lens mounts to different camera systems, maintaining a constant flange focal distance and reducing component count to minimize optical misalignment and elasticity, featuring a focusing mount with a defined distance from the camera image plane and an adapter ring with planar surfaces for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If intermediate mounts are used between lens mount and camera mount, then lens compatibility is improved, but geometrical constraints limit interchangeability
Solution Approach 1:
The mount system is divided into three separate components: the lens mount with its own fixing elements, the adapter ring with planar surfaces, and the camera mount with fixing elements. This segmentation allows each component to be independently designed for specific functions while maintaining overall compatibility across different systems.
Solution Approach 2:
The adapter ring serves as an intermediary component between the lens mount and camera mount. It features planar surfaces that interface with both the lens mount's support surfaces and the camera mount, enabling geometric transformation and compatibility between different mount types without direct conflict.
2Adaptability or versatility
If multiple components are used between focusing mount and camera, then adaptability is improved, but optical misalignment and elasticity increase
Solution Approach 1:
The adapter ring acts as a precision intermediary that bridges the focusing mount and camera mount. Its planar surfaces provide stable, flat contact areas that facilitate precise optical alignment while accommodating the necessary adaptability for different camera systems.
Solution Approach 2:
The adapter ring can be designed with specific dimensional parameters (thickness, diameter, planar surface flatness) that can be adjusted to compensate for different flange focal distances between lens mounts and camera image planes, maintaining optical precision across compatible systems.
3Adaptability or versatility
If more components are used in the mount system, then versatility is improved, but mechanical strength is reduced
Solution Approach 1:
By segmenting the mount system into distinct components (lens mount, adapter ring, camera mount), each component can be optimized for its specific mechanical function while maintaining overall versatility. The modular design allows for robust connections at each interface.
Solution Approach 2:
The adapter ring serves as a mechanically robust intermediary that distributes loads between the lens mount and camera mount. Its planar contact surfaces provide stable mechanical support while enabling interchangeability across different systems.

AI summary
A camera lens assembly includes a focusing mount having a receiving lug and optical elements, which are arranged in the focusing mount, and define an optical axis. An adapter ring has a first planar surface and a second planar surface which are parallel to each other. The first planar surface is in contact engagement against a camera-side contact surface of the focus mount and the second planar surface is in contact with a lens-side contact surface of a lens mount. The lens mount has a tubular-shaped lens mount socket and lens mount attachment elements which are configured to coact with the camera mount attachment elements of a camera.
