Interchangeable Lens Mount Insert for Smartphone Adapters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smartphone cameras lack the ability to capture images comparable to dedicated cameras due to smaller lenses, and existing lens adapters do not effectively prevent unwanted light or debris from entering, nor allow for the attachment of nonstandard external lenses.
Innovation Solution
A removable insert for lens adapters that fits into the lens mount, featuring an aperture shroud and attachment mechanisms to block unwanted light and debris while enabling the attachment of nonstandard external lenses by providing a secure and versatile interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a lens adapter is used to attach external lenses to a smartphone, then the image capturing capabilities are improved, but unwanted light and debris can still enter the camera lens
Solution Approach 1:
The lens adapter is divided into separate functional components: an adapter body that interfaces with the smartphone, and a removable insert that fits into the adapter's lens mount. This segmentation allows the insert to specifically address light and debris blocking while the adapter body provides the mounting functionality.
Solution Approach 2:
A removable insert is introduced as an intermediary component between the adapter's lens mount and the external lens. This insert acts as a mediator that selectively blocks unwanted light and debris while allowing desired light to pass through to the camera sensor.
2Device complexity
If a fixed lens mount is used in the adapter, then the structure is simple, but nonstandard external lenses cannot be attached
Solution Approach 1:
The lens mount is transformed from a fixed structure to a dynamic, interchangeable system. The removable insert can be exchanged to accommodate different lens types and mounting standards, allowing the adapter to adapt to various lens configurations while maintaining a relatively simple overall structure.
Solution Approach 2:
The adapter system achieves multi-functionality through the interchangeable insert mechanism. A single adapter body can support multiple types of external lenses by simply changing the insert, making the system universal across different lens standards without requiring multiple dedicated adapters.
3Ease of operation
If the lens mount is left open to accommodate lenses, then lens attachment is enabled, but light and debris can enter and mar the picture
Solution Approach 1:
The insert provides localized protection by blocking unwanted light and debris only at the specific locations where they would cause harm, while leaving the aperture openings necessary for desired light to reach the sensor. This selective blocking maintains ease of lens attachment while preventing contamination.
Solution Approach 2:
The insert is installed in advance before attaching the external lens, creating a protective barrier that prevents light and debris from entering the camera system. This preliminary action ensures protection is already in place when the lens is mounted, eliminating the need for additional protective measures.

AI summary
An interchangeable lens mount insert for lens adapters is positioned into a lens mount to prevent unwanted light from entering a camera lens and to allow for the attachment of nonstandard external lenses to the lens adapter. The interchangeable lens mount insert includes an aperture shroud, an aperture hole, a lens attachment mechanism, and a mount attachment mechanism. The aperture shroud obstructs the camera lens from unwanted light and debris, while the mount attachment mechanism provides a means for securing the aperture shroud to the lens mount. The aperture hole traverses the aperture shroud and allows a select amount of light to reach the camera lens. Meanwhile, the lens attachment mechanism provides a means for securing external lenses to the aperture shroud.
