Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional single spherical head lever structure is used, then the device complexity is low, but the adjustment range of the optical axis is limited
Solution Approach 1:
The lever arm is divided into multiple segments with spherical heads at different positions. Each spherical head can rotate independently around its own axis, allowing the lever arm to achieve complex spatial adjustments by combining multiple rotational movements, thereby significantly expanding the optical axis adjustment range while maintaining reasonable structural complexity
Solution Approach 2:
The patent transitions from a single spherical head providing two-degree-of-freedom rotation to a double spherical head configuration that adds a third dimension of rotation. This dimensional expansion enables the lever arm to achieve universal rotation in three-dimensional space, transforming the adjustment capability from a limited conical range to a comprehensive spatial range
2Adaptability or versatility
If a double spherical head lever arm is used, then the adjustment range is significantly expanded, but the device complexity increases
Solution Approach 1:
The double spherical head lever arm serves multiple functions: the first spherical head enables rotation around a first axis, the second spherical head enables rotation around a second axis, and together they achieve universal rotation around a third axis. This multi-functional design allows a single lever arm structure to provide comprehensive adjustment capabilities that would otherwise require multiple separate mechanisms
Solution Approach 2:
The patent employs spherical heads at both ends of the lever arm, utilizing the geometric properties of spheres to enable smooth rotation around multiple axes. The spherical geometry naturally provides the necessary degrees of freedom for universal rotation, simplifying the mechanical design compared to using complex articulated mechanisms while achieving the same adjustment range
