Product Recognition Apparatus Using Weight Verification for Settlement Accuracy

The patent introduces an intermediary verification mechanism that compares the sum of recognized product weights with the total weight detected by the weighing sensor. This intermediary comparison step enables weight measurement confirmation without requiring direct integration of complex weighing systems into the recognition apparatus, thus improving settlement accuracy while controlling device complexity through modular design.

The weighing sensor serves multiple functions: it detects total weight for verification purposes, provides data for unrecognized product detection, and supports settlement accuracy validation. By making the weighing component multi-functional, the patent improves reliability without proportionally increasing device complexity, as the same hardware performs multiple verification tasks.

The system implements a feedback mechanism where the weighing sensor continuously monitors total weight and compares it against the sum of recognized product weights. When a discrepancy is detected, the system generates feedback signals to identify unrecognized products and triggers re-scanning or alerts. This feedback loop improves recognition completeness by enabling continuous verification without requiring complex additional detection hardware.

The patent replaces complex mechanical detection systems with a simpler weight-based verification approach. Instead of using multiple cameras or sensors to detect each product's presence and orientation, the system uses a single weighing sensor to infer the presence of unrecognized products through weight discrepancy analysis, thereby improving recognition completeness while reducing device complexity.

The system performs preliminary weight measurement before product recognition to establish an expected total weight baseline. This preliminary action enables the system to anticipate and compensate for potential recognition failures due to obscured or misaligned bar codes, as the weight baseline provides a reference for detecting missing products even when visual identification fails, thereby improving adaptability without sacrificing identification accuracy for properly oriented products.

The weighing sensor acts as an intermediary verification layer between the bar code recognition system and the final settlement process. When bar code recognition fails or produces incomplete results, the weight measurement serves as an intermediate check to identify discrepancies and trigger corrective actions, thus enhancing adaptability to various product orientations and conditions while maintaining high identification accuracy for successfully scanned items.
