Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If magnetically attractable filters are used for ease of use and installation, then the ease of operation is improved, but the reliability deteriorates as they are prone to falling off during use
Solution Approach 1:
The filter system is divided into separate modular components (adapter ring, filter frames, lens elements) that can be independently assembled and disassembled. Each component has specific locking parts designed to engage with corresponding parts on adjacent components, allowing for reliable assembly while maintaining ease of operation through modular design
Solution Approach 2:
The locking parts are pre-configured on the adapter ring and filter frames in specific positions and orientations. When components are assembled, the locking parts automatically engage with each other through rotational movement, ensuring reliable connection before use without requiring additional fastening operations
2Reliability
If locking parts are added to prevent filter separation, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The locking parts are integrated directly into the existing adapter ring and filter frame structures rather than being separate additional components. The locking features are formed as part of the protruding rings and filter frame designs, combining the locking function with the structural elements already present in the filter system
Solution Approach 2:
The locking parts are designed to engage through rotational movement rather than requiring complex mechanical fastening mechanisms. The dynamic engagement of locking parts through rotation provides a simple yet reliable connection method that maintains ease of operation while ensuring safety during use

Function Achieved in This Case
Enhances safety and convenience by preventing filter separation, maintaining lens cleanliness, and simplifying operations, thus improving user experience.
Implementation Method 1
the adapter ring and adjacent filters are magnetically attracted to each other
Implementation Method 2
the first locking part and the second locking part engage with each other to achieve locking through mutual rotations between the adapter ring and the filter, and between the filters

AI summary
A magnetically attractable filter device includes an adapter ring, designed to be arranged at the front end of a lens; one or more filters, each of which includes a filter frame and a lens element, with the lens element mounted on the filter frame. The filters are sequentially stacked at the front end of the adapter ring, with the adapter ring and the adjacent filters being magnetically attracted to each other, adjacent filters being magnetically attracted to each other. Magnetically attracted ends of the adapter ring and the filter frames of the adjacent filters, as well as magnetically attracted ends of the filter frames of the adjacent filters, are respectively provided with a first locking part and a second locking part. The first locking part and the second locking part engage with each other to achieve locking through mutual rotations between the adapter ring and the filter, between the filters.
