Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple cameras and light sources are used to achieve 3D imaging and object inspection, then measurement precision and inspection capability are improved, but device complexity increases
Solution Approach 1:
The patent combines multiple cameras (first and second cameras) and multiple light sources (first and second light sources) into a single integrated optical assembly. This merging approach maintains the 3D imaging and inspection capabilities while reducing overall system complexity by consolidating components into one unified structure rather than separate units.
Solution Approach 2:
The optical assembly is designed as a multi-functional unit that performs multiple functions simultaneously: 3D imaging, object inspection, and illumination. The first and second cameras work together to capture depth and texture information, while the light sources provide structured illumination for enhanced inspection capabilities, all within a single versatile assembly.
2Adaptability or versatility
If the object handling station is designed for high flexibility to handle various objects, then adaptability is improved, but device complexity increases
Solution Approach 1:
The object handling station is designed as a universal system capable of handling multiple types of objects (pallets, totes, trays, individual items) using the same infrastructure. The optical assembly and robotic end effectors can be configured for different object types without requiring completely separate handling systems, maintaining flexibility while avoiding excessive complexity.
Solution Approach 2:
The station incorporates dynamically adjustable components including reconfigurable optical assemblies and programmable robotic end effectors that can adapt their configuration based on the specific object being handled. This dynamic reconfiguration capability provides versatility while maintaining a relatively simple base structure.
