Camera Adjustment Arrangement with Interchangeable Gearwheels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera systems, particularly dome cameras, face challenges in efficiently adjusting the lens distance to achieve optimal lens configurations using the same parts and accommodating different lenses, which complicates the optical train assembly and increases costs.
Innovation Solution
The adjustment arrangement employs a turn plate, upper turn plate, gearwheel, and sprocket stick, allowing the gearwheel to be positioned based on the lens type, with interchangeable gearwheels of varying heights to accommodate multiple lens types, and utilizes a sprocket stick with a spring-loaded mechanism to facilitate gearwheel rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the same parts are used in the optical train assembly to enable different lens settings, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal adjustment arrangement where the turn plate, upper turn plate, gearwheel, and sprocket stick serve multiple functions across different lens types. The gearwheel can be positioned in bottom or top position depending on the lens used, and interchangeable gearwheels of varying heights accommodate multiple lens types, allowing the same mechanical components to achieve different lens configurations without requiring separate adjustment mechanisms for each lens type.
2Adaptability or versatility
If interchangeable gearwheels of varying heights are used to accommodate multiple lens types, then adaptability is improved, but manufacturing precision requirements increase
Solution Approach 1:
The adjustment arrangement employs a dynamic positioning system where the gearwheel can be moved between bottom and top positions, and interchangeable gearwheels of different heights can be selected based on the lens type. This dynamic adaptability allows the same mechanical structure to accommodate multiple lens types while maintaining precise optical alignment through the spring-loaded mechanism that ensures consistent engagement regardless of gearwheel height variations.
3Ease of operation
If a spring-loaded mechanism is used to facilitate gearwheel rotation, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The spring-loaded mechanism provides self-service functionality by automatically facilitating gearwheel rotation and positioning. The spring mechanism stores and releases energy to enable smooth gearwheel engagement and positioning without requiring additional actuators or complex control systems, making the adjustment process easier while keeping the overall structure relatively simple.
