Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple filters are installed for different shooting effects, then the imaging device's versatility is improved, but the device complexity and ease of operation deteriorate due to requiring disassembly and assembly
Solution Approach 1:
Multiple filters with different shooting effects are merged into a single integrated filter assembly. The filter assembly includes multiple filters arranged in different regions, allowing the imaging device to achieve multiple shooting effects without requiring separate filters to be physically attached and detached. This resolves the contradiction by combining multiple functions into one unified structure.
Solution Approach 2:
The filter assembly is designed as a universal component that performs multiple functions simultaneously. Different regions of the filter assembly correspond to different filters, enabling a single assembly to provide various shooting effects (e.g., wide-angle, telephoto, portrait modes). This multi-functional design eliminates the need for separate filter installations while maintaining versatility.
2Adaptability or versatility
If multiple filters are carried for different shooting effects, then the imaging device's versatility is improved, but the loss of time increases due to disassembly and assembly operations
Solution Approach 1:
The filter assembly incorporates a movable structure that allows dynamic switching between different filter regions. The assembly can be positioned at different locations along the optical path depending on the desired shooting effect, enabling rapid transitions between modes without physical assembly or disassembly operations. This dynamic design significantly reduces the time required to switch between different shooting effects.
3Device complexity
If a compact housing is used, then the device complexity is reduced, but the adaptability deteriorates due to limited space for filter integration
Solution Approach 1:
The filter assembly is designed as a nested structure where multiple filters are arranged in different regions within a compact housing. The assembly includes a first filter in a first region and a second filter in a second region, allowing multiple filtering functions to be nested within a single compact structure. This nesting approach maintains device simplicity while achieving multi-functionality.
Solution Approach 2:
The filter assembly utilizes spatial arrangement in different regions (dimensions) to accommodate multiple filters within a compact housing. By distributing filters across different spatial zones rather than stacking them linearly, the design maximizes space utilization and maintains a compact form factor while providing multiple shooting effects.

AI summary
An imaging device includes a housing, a cover, a supporting plate, a filter assembly, a driving mechanism, and an imaging mechanism. The housing and the cover cooperate to define a mounting cavity. The supporting plate divides the mounting cavity into a first portion and a second portion in a first direction. A second light through hole is defined by the supporting plate. The filter assembly includes a first filter and a second filter in the first portion along a second direction. The driving mechanism extending through the supporting plate includes two driving assemblies respectively connected to the first and second filters, the driving assemblies are configured to drive the first or second filter to cover the second light through hole, or drive the first and second filters to be located on opposite sides of the second light through hole. The imaging mechanism is received in the second portion.
