Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mechanical adjustment mechanism with threaded elements is used to adjust the reticle position, then the reticle position can be adjusted, but the complexity of precisely determining the reticle position increases
Solution Approach 1:
The patent replaces complex mechanical position determination mechanisms with a magnetic detection system. Magnetic elements are integrated into the adjustment mechanism, and magnetic sensors detect their position to determine reticle position, thereby simplifying the overall system while maintaining adjustment functionality
Solution Approach 2:
The patent introduces magnetic elements as intermediaries between the mechanical adjustment mechanism and the detection system. These magnetic elements couple the mechanical movement to the magnetic sensors, enabling indirect but precise detection of the reticle position without complex direct mechanical measurement
2Measurement precision
If magnetic elements are integrated into the adjustment mechanism to detect reticle position, then detection precision is improved, but device complexity increases
Solution Approach 1:
The patent merges the magnetic detection elements directly into the existing adjustment mechanism components. The magnetic elements are integrated into the movable parts of the adjustment mechanism, combining the adjustment function and detection function into a unified structure, thereby improving precision without proportionally increasing complexity
Solution Approach 2:
The adjustment mechanism components serve dual functions: mechanical adjustment of the reticle position and magnetic field generation for position detection. This multi-functionality reduces the need for separate detection components, balancing precision improvement with complexity management
