Solution Overview

Problem

Ambient commerce systems struggle to handle restricted items, particularly age-restricted goods, as they lack the capability to verify a customer's age during the checkout process, necessitating a traditional checkout process.

Innovation Solution

An ambient commerce system equipped with sensors and processors that detect engagement with restricted items, identify the entity, obtain a profile, determine eligibility, and generate notifications or prompts for secondary identity verification on electronic devices, enabling age affirmation without manual intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If ambient commerce system uses traditional checkout process to verify customer age, then age verification accuracy is improved, but checkout speed deteriorates

Engineering Contradiction:
Improveage verification accuracyVSAvoidcheckout speed
Core Design Contradiction:
Measurement precisionVSSpeed

Solution Approach 1:

The system performs age verification in advance by detecting customer characteristics (such as facial recognition or ID scanning) before the checkout process completes. This preliminary action ensures age verification accuracy is achieved without requiring a separate traditional checkout step, thereby maintaining fast checkout speed.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces the manual mechanical checkout process with an automated sensor-based system that uses optical, acoustic, or other non-contact sensing methods to verify customer age and process payment. This substitution eliminates the need for physical interaction at the checkout counter while maintaining verification accuracy.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If ambient commerce system implements traditional checkout process for restricted items, then age verification capability is improved, but device complexity deteriorates

Engineering Contradiction:
Improveage verification capabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The ambient commerce system integrates multiple functions into a single unified process: customer identification, age verification, restricted item detection, and payment processing all occur simultaneously through the sensor network. This multi-functionality eliminates the need for separate traditional checkout infrastructure while maintaining age verification capability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system introduces an intermediary processing layer that acts as a bridge between sensor detection and checkout execution. This intermediary automatically handles age verification logic and coordination, simplifying the overall system architecture by centralizing control rather than requiring complex point-to-point integrations between multiple systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If ambient commerce system allows cashier-less experience, then ease of operation is improved, but ability to handle restricted items deteriorates

Engineering Contradiction:
Improvecashier-less experienceVSAvoidrestricted item handling capability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system enables self-service for restricted items by automatically performing age verification and compliance checks without requiring cashier intervention. Sensors detect customer identity and verify eligibility for restricted items in real-time, allowing the cashier-less experience to continue uninterrupted while maintaining restricted item handling capability.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The ambient commerce system implements real-time feedback loops where sensors continuously monitor customer actions and system responses. When a restricted item is detected, the system immediately verifies customer eligibility and provides feedback (such as notifications or access control) to ensure compliance, all within the cashier-less framework.

Inventive Principle:
Principle #23Feedback

AI summary

An ambient commerce system may include a sensor at an ambient commerce premises, a processor coupled to the one or more sensors, a memory coupled to the processor. The memory may store processor-executable instructions which cause the processor to: detect, based on an output of one or more of the sensors, engagement of an entity with a restricted item; identify the entity; obtain at least a portion of a profile for the entity; determine, based on the at least a portion of the profile for the identified entity, eligibility for the entity to acquire the restricted item; and selectively generate, based on the determined eligibility for the entity, a notification on an electronic device associated with the entity. When the entity is eligible to exit the premise with the restricted item, a notification may trigger on a device to collect input via facial recognition from an image recognition sensor.
