Multi-Filter Lens Hood for Independent Yaw, Roll, and Pitch Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lens hoods and filters are often incompatible, leading to issues such as vignetting and difficulty in handling large filters, and there is a need for a solution that allows for simultaneous use and independent rotation of multiple filters during photography.
Innovation Solution
A lens hood design with recesses for receiving multiple filters, featuring independent yaw, roll, and pitch rotations, allowing for easy attachment and detachment without removing the hood, and incorporating non-reflective inner surfaces to prevent light interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple filters are used simultaneously, then light control capability is improved, but device complexity and handling difficulty increase
Solution Approach 1:
The patent combines multiple filters into a single integrated filter system mounted within the lens hood structure. The filter holder assembly integrates multiple filter slots, rotation mechanisms, and mounting features into one unified device that attaches to the lens, eliminating the need to manage separate filters and reducing overall system complexity.
Solution Approach 2:
The lens hood is designed with multi-functionality to serve both as a traditional lens hood and as an integrated filter holder. The structure includes universal mounting features that can accommodate various filter types and configurations, allowing a single device to perform multiple functions including light blocking and multi-filter manipulation.
2Adaptability or versatility
If large filters are used, then light control capability is improved, but ease of operation deteriorates due to handling difficulty
Solution Approach 1:
The filter system is segmented into multiple independent slots within the holder, each capable of holding and rotating filters independently. This segmentation allows operators to access and adjust individual filters without manipulating the entire assembly, making large filter handling easier while maintaining comprehensive light control capability.
Solution Approach 2:
The filter holder incorporates dynamic rotation mechanisms that allow filters to be rotated independently around the optical axis. This dynamic capability enables easy adjustment of filter orientations and facilitates quick changes between different filter configurations without requiring complete removal and reattachment of the filter system.
3Stability of the object's composition
If filters are fixed to the lens hood, then stability is improved, but adaptability deteriorates due to inability to rotate independently
Solution Approach 1:
The patent implements dynamic rotation mechanisms that allow filters to be securely mounted yet freely rotated around the optical axis. Each filter is held in a dedicated slot with rotation features that provide stable mounting during exposure while enabling independent rotation for different filter orientations and configurations.
Solution Approach 2:
The filter holder system allows changes in orientation parameters for each filter independently. The rotation mechanisms enable adjustment of angular parameters while maintaining radial positioning stability, providing both stable mounting and adaptability for different photographic requirements.
4Adaptability or versatility
If recesses for filters are added to the lens hood, then filter integration is improved, but manufacturing complexity increases
Solution Approach 1:
The filter recesses and holder features are merged into the lens hood manufacturing process as integrated components. The holder assembly includes molded-in recesses, snap-fit features, and mounting threads that are incorporated during lens hood production, reducing the need for separate manufacturing steps and assemblies.
Solution Approach 2:
The lens hood structure incorporates universal mounting features and standardized recess geometries that can accommodate various filter types. This universal design approach simplifies manufacturing by using standardized features rather than custom-designed interfaces for each filter type.

AI summary
A lens hood system designed to accommodate one or more lens filters via one or more recesses. The lens filters may be inserted through various access points, including front, back, or side openings, and can be secured using methods such as threading, snap-fit tabs, or sliding mechanisms. The lens hood may be equipped with movable frame portions allowing for roll, pitch, and yaw rotations of the filters, independently or collectively, to optimize filter alignment. Additionally, the inner surfaces of the lens hood may be non-reflective or feature designs to minimize unwanted light reflections, enhancing image quality.
