Product Location Confirmation Using Subset of Identifier Digits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-store voice workflows require product verification, but the display of separate check digits clutters the environment and confuses shoppers, making them unsuitable for in-store use.
Innovation Solution
A method and system that use a subset of digits from existing product identifiers like UPC or SKU for product location confirmation, reducing the need for additional check digits and minimizing environmental clutter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate check digits are displayed for product verification, then verification accuracy is improved, but visual clutter and shopper confusion increase
Solution Approach 1:
The patent merges the check digit function with existing product identification codes (UPC, SKU, or location codes) that are already displayed on shelves. Instead of displaying separate check digits, the system uses a subset of digits from these existing codes to serve as check digits, thereby eliminating additional visual clutter while maintaining verification accuracy.
Solution Approach 2:
The existing product identification codes serve multiple functions: they identify the product/location and simultaneously provide the check digits for verification. This multi-functionality eliminates the need for separate check digit displays while maintaining verification capabilities.
2Reliability
If additional check digits are displayed, then product verification reliability is improved, but device complexity and visual clutter increase
Solution Approach 1:
The verification function is merged with the existing product identification display. The same code that identifies the product also serves as the verification mechanism, eliminating the need for separate check digit displays and reducing overall system complexity.
Solution Approach 2:
The existing product identification codes perform dual functions: product identification and verification. This eliminates the need for additional verification components while maintaining reliability.
3Object-affected harmful factors
If a subset of digits is used instead of full check digits, then visual clutter is reduced, but verification precision may be compromised
Solution Approach 1:
Instead of using the full product identification code for verification, the system uses a strategically selected subset of digits (typically 2-5 digits) that provides sufficient verification precision while minimizing visual clutter. This partial action approach achieves the minimum necessary verification without displaying excessive information.
Data Source
AI summary
A system and method include providing product location information to a user; prompting a user to provide check digits; receiving a subset of digits from a set of digits associated with a product that are used for a purpose different than for check digits; and comparing the subset of digits to product check digits to confirm the user has located the product.
