Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual barcode scanning is performed by store workers, then product checkout can be accurately performed, but customer waiting time increases and operational costs increase due to employee hiring

Engineering Contradiction:
Improveproduct recognition accuracyVSAvoidcustomer waiting time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system enables self-service checkout where customers place products on the transfer unit and the automated system performs scanning, identification, and classification without requiring store employees. The guide devices automatically guide products through the scanning path, and the processor automatically identifies products using barcode scanning and image recognition, eliminating the need for manual operation while maintaining accuracy.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical barcode scanning with automated optical scanning systems. The scan unit uses optical sensors to capture barcode images and product images, which are then processed by the processor using image recognition algorithms. This substitution of mechanical manual scanning with automated optical and computational systems eliminates human labor while improving scanning speed and accuracy.
