Solution Overview
Problem
Photographers face the inconvenience of frequently swapping camera lenses and filters due to the need for specific sizes that match each other, leading to inefficiencies in capturing different scenes and requiring multiple sets of filters and lenses.
Innovation Solution
A camera filter adaptor kit with a lens engagement apparatus and a filter retaining apparatus that allows for quick and secure mounting of camera filters across different lens sizes through a locking mechanism, enabling the use of filters with varying diameters on a single lens and vice versa, facilitated by magnetic coupling for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If camera filters are directly mounted to camera lenses using traditional threading, then secure attachment is achieved, but frequent swapping of lenses and filters becomes time-consuming and inefficient
Solution Approach 1:
The system divides the filter mounting mechanism into separate components: a filter holder with magnetic attachment mechanism and the lens itself. This segmentation allows the filter holder to be quickly attached or detached from the lens without moving the entire lens assembly, enabling rapid filter changes while maintaining secure attachment during use.
Solution Approach 2:
The patent replaces traditional mechanical threading systems with a magnetic coupling mechanism. The magnetic attraction provides sufficient holding force for secure attachment during photography, while allowing for quick release when needed, dramatically reducing the time required for filter swaps compared to unscrewing and rescrewing threaded connections.
2Adaptability or versatility
If multiple sets of filters and lenses are maintained for different sizes, then compatibility across different lens diameters is ensured, but device complexity and the number of components required increases
Solution Approach 1:
The filter holder is designed with universal adaptability through interchangeable adapter rings that can accommodate different lens diameters. Instead of requiring separate filters for each lens size, the same filter can be mounted on different lenses by changing the adapter ring, reducing the total number of components needed while maintaining full compatibility across the lens collection.
Solution Approach 2:
The adapter ring serves as an intermediary component between the filter holder and the lens. This intermediate element allows the filter holder to interface with lenses of various diameters without requiring the filter itself to be customized for each lens size, simplifying the overall system while preserving adaptability.
3Productivity
If quick-release mechanisms are implemented for filter swapping, then operational efficiency improves, but attachment security and reliability may be compromised
Solution Approach 1:
The magnetic attachment mechanism provides dynamic characteristics: strong holding force during normal operation to ensure security, but easy release when a small release force is applied. This dynamic behavior allows the system to maintain reliability during use while enabling rapid changes when needed, resolving the contradiction between security and speed.
Solution Approach 2:
The magnetic force parameters are carefully selected to provide sufficient attraction strength for secure attachment under normal conditions, while the release mechanism is designed to overcome this magnetic force with minimal applied force. This parameter optimization ensures both reliable attachment during photography and quick release for filter changes.

AI summary
A kit for a camera filter adaptor includes a filter retaining apparatus and a lens engagement apparatus. The filter retaining apparatus has a filter retaining portion and a first interfacing portion opposite the filter retaining portion. The retaining portion is configured for retaining a camera filter. The lens engagement apparatus has a lens coupling portion and a second interfacing portion. The lens coupling portion is configured for being coupled to a camera lens. The second interfacing portion is configured for interfacing with the first interfacing portion of the filter retaining apparatus to form an engagement therewith. The interfacing defines an interfacing diameter that is greater than a lens coupling diameter. A method for using the kit is also provided.
