Rotatable Mobile Camera Filter Assembly for Aquarium Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Amateur photographers using mobile devices face challenges in obtaining quality images of aquarium scenes and similar optical environments due to the lack of a simple and effective optical color filter system for mobile device cameras.
Innovation Solution
A mobile device camera filter assembly featuring a holder and mounting plate that can be attached to a device case, with a rotatable filter frame and light filter system that can be easily positioned over the camera lens, allowing for the use of one or more filters and accommodating different device sizes and camera lens orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a filter system is added to mobile device cameras, then image quality in challenging optical environments is improved, but device complexity increases
Solution Approach 1:
The filter system is segmented into separate components: a mounting plate that attaches to the device case, a holder that receives the filter frame, and a rotatable filter frame containing the actual filter. This segmentation allows the filter functionality to be added without modifying the mobile device itself, thereby improving image quality while minimizing the increase in overall device complexity.
Solution Approach 2:
The patent introduces an intermediary mounting structure (mounting plate and holder) that mediates between the mobile device and the filter system. This intermediary approach allows the filter to be attached externally to the device case rather than integrating it into the device itself, resolving the contradiction by adding filter functionality while keeping the device structure relatively simple.
2Adaptability or versatility
If a rotatable filter frame is used, then adaptability to different camera lens orientations is improved, but device complexity increases
Solution Approach 1:
The filter frame is designed to be rotatable rather than fixed, allowing it to dynamically adjust to different camera lens orientations. The hinge connection between the holder and filter frame enables this rotational movement, providing adaptability to various device configurations while maintaining a relatively simple mechanical structure that does not significantly increase overall device complexity.
3Adaptability or versatility
If multiple filters are accommodated, then versatility of the filter system is improved, but device complexity increases
Solution Approach 1:
The holder and mounting plate structure is designed with universal functionality to accommodate multiple different filter frames. The standardized interface and rotatable design allow the same holder structure to work with various filters (e.g., different colors, polarizers), providing versatility without requiring separate mounting mechanisms for each filter type, thereby avoiding excessive increase in device complexity.
