Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single imaging assembly is used for barcode reading, then the device structure is simple, but the ability to detect shrink events and measure weight simultaneously is insufficient
Solution Approach 1:
The patent combines multiple imaging assemblies (first and second imaging assemblies with different fields of view) and a weigh platter with integrated sensors into a single barcode reader device. This merging allows simultaneous barcode reading, shrink event detection, and weight measurement, resolving the contradiction by enabling multiple detection capabilities while maintaining a unified device structure.
Solution Approach 2:
The imaging assemblies are designed to serve multiple functions: the first imaging assembly captures images through the horizontal window for barcode reading, while the second imaging assembly positioned at the distal edge detects shrink events. The weigh platter simultaneously measures weight and provides a scanning surface. This multi-functionality resolves the contradiction by enabling diverse detection capabilities within a single device.
2Loss of information
If imaging assemblies are positioned to cover all scanning regions, then comprehensive image data is captured, but operational interference between weight measurement and barcode reading increases
Solution Approach 1:
The patent divides the imaging function into two separate imaging assemblies with distinct fields of view: the first imaging assembly is positioned to capture images through the horizontal window for barcode reading, while the second imaging assembly is positioned near the distal edge to detect shrink events. This segmentation allows each assembly to operate independently without interfering with weight measurement, resolving the contradiction by capturing comprehensive image data while maintaining operational integrity.
Solution Approach 2:
Each imaging assembly is optimized for its specific function: the first imaging assembly has its field of view directed through the horizontal window for optimal barcode reading, while the second imaging assembly is positioned near the distal edge with its field of view oriented to detect shrink events. This local optimization ensures each component performs its specific function effectively without creating operational interference.
3Illumination intensity
If the weigh platter has a traditional flat design, then manufacturing is simple, but light transmission and multi-directional imaging are limited
Solution Approach 1:
The weigh platter is designed with an asymmetric structure featuring a proximal edge, a distal edge, and lateral edges at different positions. The distal edge is specifically positioned to allow the second imaging assembly to be mounted near it, enabling multi-directional imaging. This asymmetric design improves light transmission and imaging capability while remaining manufacturable through standard fabrication processes.
Solution Approach 2:
The patent transitions from a traditional flat two-dimensional platter design to a three-dimensional structure with elevated edges and a central scanning region. The distal edge is positioned at a specific location to accommodate the second imaging assembly, adding a vertical dimension to the platter structure. This dimensional change enables improved light transmission paths and multi-directional imaging while maintaining ease of manufacture through standard fabrication techniques.
