Rotatable Imaging Camera Base for Aspect Ratio Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surveillance cameras with multiple lenses face limitations in monitoring large areas due to fixed aspect ratios, preventing selective monitoring of horizontal or vertical regions based on installation purposes.
Innovation Solution
An imaging apparatus with a rotatable base and guide system, including a torsion spring, allows for changing photographing modes between horizontal and vertical orientations by rotating the camera lenses and sensors within a preset angle, maintaining a constant central axis of rotation and improving position representation and stitching performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single imaging apparatus with fixed lenses is used, then the device complexity is reduced, but the adaptability to monitor different areas (horizontal or vertical) is limited
Solution Approach 1:
The patent applies the dynamics principle by making the base rotatable to change the photographing mode between horizontal and vertical orientations. The base can rotate within a preset angle range about a central axis of rotation, allowing the imaging apparatus to dynamically adapt to different monitoring requirements without changing the physical installation position. This resolves the contradiction by enabling adaptability through motion rather than through multiple fixed devices.
2Adaptability or versatility
If the base rotates to change photographing mode, then the adaptability is improved, but the position representation and stitching performance may deteriorate due to central axis movement
Solution Approach 1:
The patent applies equipotentiality by ensuring that the guide contacts the frame at multiple points along the rotation path, creating a constraint system where the central axis of rotation remains at a constant potential position. The guide body with multiple guide contacts prevents radial displacement of the central axis during rotation, maintaining consistent reference points for position representation and image stitching across different photographing modes.
3Ease of operation
If the base rotates without guide constraint, then the ease of operation is improved, but the stability of the central axis position deteriorates
Solution Approach 1:
The patent introduces the guide as an intermediary component between the base and the frame. The guide body, which rotates with the base, makes contact with the frame at multiple guide contact points. This intermediary structure allows the base to rotate freely for ease of operation while simultaneously constraining the central axis position through the frame contacts, thus maintaining stability without interfering with the rotation operation.
