Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-purpose inspection device is used, then the device structure is simple, but the versatility and adaptability for different lens types are limited
Solution Approach 1:
The inspection device is designed with multiple interchangeable lenses (e.g., +10.00D, +20.00D, +30.00D spherical lenses and cylindrical lenses) that can be selectively mounted on the same device platform. This allows a single device to perform multiple inspection functions for different lens types and prescriptions, achieving versatility without requiring separate dedicated devices for each lens type.
Solution Approach 2:
The lens system is segmented into interchangeable components rather than a fixed single lens. Each lens can be independently selected and mounted on the inspection device, allowing the system to be divided into modular functional units that can be reconfigured based on inspection requirements.
2Adaptability or versatility
If interchangeable lenses are added to enhance versatility, then the adaptability improves, but the device complexity and storage requirements increase
Solution Approach 1:
Multiple lenses are stored in a compact nested arrangement within the device housing. The lenses are arranged in a space-efficient manner where smaller lens cases or holders are nested within larger ones, or lenses are stacked in a compact configuration, allowing multiple lenses to be stored within the device without significantly increasing its external dimensions.
Solution Approach 2:
The storage mechanism is merged with the lens mounting mechanism. The same structural components serve dual purposes: storing the interchangeable lenses and facilitating their quick exchange. This integration reduces the need for separate storage compartments and simplifies the overall device structure.
3Measurement precision
If alignment mechanisms are implemented for interchangeable lenses, then the inspection accuracy improves, but the device complexity increases
Solution Approach 1:
The lens mounting structure incorporates self-aligning features such as tapered seats, cam-locked mechanisms, or spring-loaded holders that automatically center and position the interchangeable lens when mounted. This self-aligning capability ensures consistent optical alignment without requiring complex external adjustment mechanisms or manual calibration procedures.
Solution Approach 2:
Complex mechanical adjustment mechanisms for lens alignment are replaced with simpler optical alignment methods. The device may include reference marks, alignment indicators, or optical axes that guide the user in positioning the lens correctly, substituting complex mechanical adjustment systems with easier-to-use alignment aids.
