Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If conventional electric pan/tilt cameras use rotating mechanisms with complex structures (such as industrial multi-way slip rings) to achieve 360-degree rotation, then the monitoring range is expanded, but the device complexity increases and reliability decreases
Solution Approach 1:
The patent extracts and removes the complex slip ring component from the rotating mechanism. Instead of using a traditional slip ring structure, the invention employs a brushless direct current motor with a built-in encoder that directly drives the camera module to rotate, eliminating the need for external slip rings and complex wiring connections between rotating and stationary parts.
Solution Approach 2:
The patent merges the motor, encoder, and camera mounting structure into an integrated rotating mechanism. The brushless direct current motor's rotor is directly coupled to the camera module, and the encoder is integrated within the motor structure, combining multiple functions (rotation drive, position sensing, and camera mounting) into a single unified assembly that simplifies the overall device structure.
2Area of stationary object
If conventional electric pan/tilt cameras use complex rotating mechanisms to achieve 360-degree rotation, then the monitoring range is expanded, but the manufacturing cost increases
Solution Approach 1:
The patent removes the expensive industrial multi-way slip ring component from the design. By using a brushless direct current motor with integrated encoder and direct-drive mechanism, the invention eliminates the need for complex sliding contacts and associated high-precision manufacturing requirements, thereby reducing manufacturing costs.
Solution Approach 2:
The patent adopts a more economical rotating mechanism using standard brushless direct current motors that are widely available and cost-effective compared to specialized industrial slip ring systems. The simplified structure with fewer high-precision components reduces both initial manufacturing costs and long-term maintenance expenses.
3Area of stationary object
If conventional electric pan/tilt cameras use complex rotating mechanisms, then 360-degree rotation is achieved, but the product failure rate increases and reliability is reduced
Solution Approach 1:
The patent extracts and eliminates the slip ring component, which is a known failure point in rotating mechanisms due to wear, contact resistance, and mechanical stress. The brushless direct current motor with encoder and direct-drive configuration removes these reliability-critical components, resulting in a more robust and maintenance-free rotating system.
Solution Approach 2:
The patent replaces the mechanical slip ring contact system with an electromagnetic brushless direct current motor system. This substitution eliminates mechanical wear, contact resistance, and friction associated with sliding contacts, thereby significantly improving the reliability and lifespan of the rotating mechanism.
