Tilted Camera Lens Mounting Barrel for Wide-Angle View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current camera lenses on terminal devices have limited view angles, making wide-angle photography impossible without modifying the existing camera lenses, which is difficult due to the fixed mounting mechanisms.
Innovation Solution
A camera device with a mounting barrel and rotating ring system that allows the camera lens to be tilted, utilizing elastic members and a driving motor to change the angle of the lens, enabling a larger view angle without rotating the lens itself, thus allowing for wide-angle photography with standard camera lenses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If camera lenses are directly mounted on terminals with fixed mounting mechanisms, then the structure is simple and easy to manufacture, but the view angle is limited and wide-angle photography is impossible
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed mounting structure into a movable one. The camera lens is mounted on a rotating ring that can rotate around a vertical axis, and the mounting barrel can tilt relative to the rotating ring. This dynamic structure allows the camera lens to capture images from multiple angles, achieving wide-angle photography capability while maintaining a relatively simple overall structure.
Solution Approach 2:
The patent implements dimensionality change by adding rotational and tilting degrees of freedom to the camera lens mounting. Instead of a single fixed position, the lens can now move in multiple dimensions - rotating around the vertical axis and tilting at an angle, thereby expanding the view angle without requiring a complex multi-component mounting system.
2Adaptability or versatility
If the camera lens is tilted using elastic members and driving motor, then wide-angle photography is enabled, but the device complexity increases
Solution Approach 1:
The patent partially applies mechanics substitution by using elastic members (such as elastic sheets or springs) to maintain the tilting state of the mounting barrel, replacing the need for complex mechanical locking mechanisms. The driving motor provides the necessary force to overcome elastic resistance and adjust the tilting angle, simplifying the overall control system while enabling versatile photographing capabilities.
3Adaptability or versatility
If the mounting barrel is inclined with respect to the rotating ring, then the view angle is enlarged, but the manufacturing precision requirements increase
Solution Approach 1:
The patent applies self-service principle through the elastic members that automatically maintain the inclined relationship between the mounting barrel and rotating ring. The elastic force continuously pushes the mounting barrel to its designated tilting angle, providing self-positioning and self-maintaining functionality. This reduces the need for high-precision fixed angular alignment during manufacturing, as the elastic mechanism compensates for minor variations.
