Low-Profile Lens Mount with Rotating Lock Ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Compact imaging devices, such as smartphones and action cameras, lack compatibility with high-quality lenses typically used in professional cameras due to differences in flange focal distance and mounting systems.
Innovation Solution
A low-profile, positive lock camera component with a rotatable lock ring and projections that allows for removable attachment of lenses, enabling a reduced flange focal distance and secure locking mechanism, compatible with various lens mounts and imaging devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional lens mount system is used in compact imaging devices, then the device maintains a compact size, but the lens compatibility is limited to lower quality lenses
Solution Approach 1:
The lens mount adapter incorporates a universal mounting interface that can accommodate multiple lens types and flange focal distances. The adapter includes a rotatable lock ring with projections that engage with corresponding recesses in the imaging device, allowing secure attachment of various lenses while maintaining compatibility across different camera systems.
Solution Approach 2:
The adapter serves as an intermediary component between the imaging device and the lens. It includes a first interface for attachment to the imaging device housing and a second interface for attachment to the lens, effectively mediating the connection between incompatible components and enabling universal lens compatibility.
2Length of moving object
If the flange focal distance is reduced to maintain compact device size, then the device remains small, but the mounting mechanism becomes more difficult to implement
Solution Approach 1:
The mounting mechanism is segmented into distinct functional components: a stationary plate with recesses, a rotatable lock ring with projections, and a button mechanism. This segmentation allows each component to be manufactured independently and assembled together, simplifying the manufacturing process while achieving the reduced flange focal distance.
Solution Approach 2:
The lock ring is designed to be rotatable, transforming a static mounting structure into a dynamic one. The rotation of the lock ring engages and disengages the projections with the recesses, providing a simple yet effective locking mechanism that is easy to manufacture and operate.
3Reliability
If a secure locking mechanism is implemented to prevent lens play during motion, then the lens attachment becomes secure, but the device profile increases
Solution Approach 1:
The locking mechanism is nested within the compact adapter structure. The projections are positioned within the recesses such that when engaged, they provide secure locking without protruding beyond the device profile. The button mechanism is integrated into the lock ring, allowing the entire assembly to remain compact while maintaining reliability.
