Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed lens assembly is used in the optical video measurement system, then the measurement precision is maintained, but the adaptability to different magnification requirements is reduced
Solution Approach 1:
The patent implements a universal mounting system that accepts multiple interchangeable lens assemblies with different focal lengths and magnification capabilities. The standardized interface allows a single camera body to perform multiple measurement functions by simply changing the lens assembly, enabling the system to adapt to various part sizes and measurement requirements while maintaining precision through calibrated lens options.
2Adaptability or versatility
If interchangeable lens assemblies are introduced to improve adaptability, then the versatility increases, but the device complexity increases
Solution Approach 1:
The patent employs a standardized universal mounting interface that simplifies the interchangeability process. All lens assemblies use the same coupling mechanism, allowing users to switch between different lenses without complex alignment procedures or recalibration, thus reducing the operational complexity despite having multiple lens options.
Solution Approach 2:
The system includes pre-calibrated lens assemblies that are prepared in advance with known optical characteristics. This preliminary calibration eliminates the need for users to perform complex calibration procedures when changing lenses, as each lens assembly comes with predetermined optical parameters that the system already accounts for.
3Adaptability or versatility
If multiple interchangeable lens assemblies are provided, then the adaptability to different measurement tasks is improved, but the loss of time for lens changes increases
Solution Approach 1:
The patent implements a dynamic lens change capability where lens assemblies can be quickly swapped during measurement operations. The mounting system is designed to allow rapid attachment and detachment of lenses without requiring complex alignment or recalibration procedures, enabling the system to dynamically adapt to different measurement tasks with minimal time loss.
