Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a scanner captures radiation from multiple viewpoints to create accurate 3D representations, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The scanning system is segmented into modular components: a sensor device (camera), a motorized positioning system, and a processor. The sensor device can be detached and reattached at different positions around the object, allowing multiple viewpoint capture without requiring a complex fixed multi-camera system. This segmentation reduces overall device complexity while maintaining measurement precision.
Solution Approach 2:
The system employs dynamic positioning where the sensor device is moved to different viewpoints around the object using a motorized positioning system. This dynamic approach allows a single sensor to capture radiation from multiple angles sequentially, replacing the need for multiple fixed sensors and reducing system complexity while achieving accurate 3D representations.
2Measurement precision
If the sensor device is moved to capture radiation from different viewpoints, then 3D representation quality is improved, but reliability decreases due to vibrations and disturbances
Solution Approach 1:
The system performs preliminary positioning of the sensor device to predetermined viewpoints before capturing radiation. The motorized positioning system moves the sensor to predetermined positions around the object, and the processor is configured to capture images only when the sensor is at these predetermined positions. This preliminary positioning ensures stability and reduces vibrations during the actual capture process, maintaining reliability while achieving high-quality 3D representations.
Solution Approach 2:
The system incorporates feedback mechanisms where the processor monitors the positioning of the sensor device and adjusts for any deviations. The processor is configured to capture radiation only when the sensor device is properly positioned at predetermined viewpoints, providing feedback control that reduces the impact of vibrations and disturbances, thereby maintaining scanning reliability.
3Ease of operation
If coupling members are used to connect toy construction elements, then ease of operation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The coupling members are designed to be self-aligning and self-latching, allowing users to easily connect toy construction elements without requiring precise manual alignment. The coupling mechanism automatically guides the elements into proper alignment and secures them, reducing the manufacturing precision requirements while maintaining ease of operation for end users.
