Solution Overview
Problem
Existing adapters for coupling smartphones to optical devices, such as telescopes, lack adjustable mechanisms, leading to poor image quality due to misalignment and vignetting, and insecure attachments that cause shifting during use.
Innovation Solution
A smartphone adapter with a spring-loaded clamp and adjustable rack-and-pinion mechanisms for precise positioning along the X, Y, and Z axes, along with a locking mechanism to secure the adapter to the optical device, ensuring stable and focused image capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple clamp connection is used to attach the adapter to the optical device, then the device complexity is reduced and ease of manufacture is improved, but the reliability of the connection deteriorates due to sagging and shifting under gravity and user pressure
Solution Approach 1:
The clamp mechanism incorporates a spring element that provides dynamic adjustment capability. The spring allows the clamp to adapt to different optical device diameters and maintains consistent clamping force despite variations in device weight or external pressures, resolving the contradiction between simple design and reliable connection.
Solution Approach 2:
The clamp mechanism allows adjustment of clamping force and position parameters. By changing the clamping force parameter through the spring mechanism and adjusting the position parameter along the optical axis, the system achieves reliable connection without requiring an overly complex fixed-connection design.
2Reliability
If the spring clamp is made very tight to prevent movement, then the connection reliability is improved, but the ease of operation deteriorates because the clamp becomes very difficult to open by hand
Solution Approach 1:
The clamp mechanism is segmented into a spring-loaded clamping component and a separate locking component. This segmentation allows the spring to provide gentle, easily operable clamping force for attachment, while the locking mechanism provides the additional security needed for reliable connection during use, resolving the contradiction between ease of opening and connection stability.
3Device complexity
If no adjustment mechanism is provided, then the device complexity is reduced, but the manufacturing precision of image capture deteriorates due to vignetting and cropping from improper positioning
Solution Approach 1:
The adapter incorporates adjustable mechanisms along the optical axis that allow dynamic positioning of the smartphone camera relative to the optical device. This dynamic adjustment capability enables precise positioning to eliminate vignetting and cropping, resolving the contradiction between simple design and positioning accuracy.

AI summary
An adapter may be used to couple an imaging device, such as a smartphone, to an optical device such as a telescope. The adapter may have an optical device mounting feature that mounts the adapter to the optical device, an imaging device mounting feature that mounts the imaging device to the adapter, and a positioning mechanism that adjustably positions the imaging device mounting feature relative to the optical device mounting feature. The optical device mounting feature may have a first arm, a second arm that is movable relative to the first arm to clamp a portion of the optical device between the first arm and the second arm, and a lock that can be actuated to restrict motion of the second arm away from the first arm. The positioning mechanism may be actuatable to move the imaging device, relative to the optical device, along three orthogonal axes.
