Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a fixed barcode scanner is used at point-of-sale systems, then the scanner can continuously scan barcodes, but the operator must manually position and rotate the article to make the barcode visible
Solution Approach 1:
The patent transitions from a single fixed scanning position to multiple scanning positions arranged in an arcuate path. This dimensional change allows the robotic arm to access barcodes from various angles and positions, automatically detecting barcodes without requiring manual article rotation by the operator.
Solution Approach 2:
The system enables self-service by allowing the robotic arm to autonomously position itself at appropriate scanning locations and detect barcodes without human intervention. The robotic arm independently navigates the arcuate structure and positions scanning devices to automatically read barcodes on articles.
2Productivity
If manual barcode scanning is used, then the operator can identify articles, but the sorting process requires significant human labor and time
Solution Approach 1:
The patent replaces manual mechanical sorting operations with an automated robotic system. The robotic arm, controlled by a processor, automatically positions scanning devices and reads barcodes, eliminating the need for human operators to manually handle and scan each article, thereby significantly increasing sorting speed and automation.
3Adaptability or versatility
If industrial barcode scanners are placed in fixed locations relative to a conveyor, then scanning can be automated, but the range of barcode positions and orientations is tightly controlled and limited
Solution Approach 1:
The patent introduces dynamic positioning capabilities where the robotic arm can move scanning devices to various positions along an arcuate structure. This dynamic adjustment allows the system to adapt to different barcode positions and orientations on articles, overcoming the limitations of fixed-location scanners while managing complexity through controlled robotic movement.
Solution Approach 2:
The robotic arm system serves multiple functions: it can position scanning devices at various locations, adjust scanning angles, and handle different article types and orientations. This multi-functionality allows a single system to replace multiple fixed scanners, increasing adaptability to various barcode positions while consolidating system complexity into one versatile platform.
