Solution Overview

Problem

Existing systems in materials handling facilities face challenges in accurately determining user, action, and item aspects of events, such as picking or placing items, due to uncertainties in image processing and sensor data interpretation.

Innovation Solution

A system and method that utilize image capture devices, sensors, and inventory management software to process images and sensor data to determine the user, action, and item involved in events, with confidence scoring to ensure accuracy and generate user interfaces for confirmation when necessary.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If image processing and sensor data interpretation are used to determine event aspects, then automation and productivity are improved, but measurement precision and reliability deteriorate due to uncertainties in data interpretation

Engineering Contradiction:

Improveautomation of event determinationVSAvoidaccuracy of event aspect determination

Core Design Contradiction:

Extent of automationVSMeasurement precision

Solution Approach 1:

The system presents determined event aspects to the user through a user interface and requests confirmation or correction. This feedback loop allows the automated system to verify its determinations and correct errors, thereby maintaining high automation while improving measurement precision through user validation.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The determination process is divided into discrete event aspects (user, action, item) that are determined and presented separately. This segmentation allows the system to handle each aspect independently and seek specific confirmations, improving overall accuracy while maintaining automation.

Inventive Principle:

Principle #1Segmentation

2Reliability

If confidence scoring is implemented to ensure accuracy, then reliability is improved, but loss of time increases due to additional verification steps

Engineering Contradiction:

Improveconfidence in event determinationVSAvoidtime for verification

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system requests user confirmation only when confidence scores indicate uncertainty about event aspects. When confidence is high, the system proceeds without additional verification. This partial application of verification reduces time loss while maintaining reliability for critical determinations.

Inventive Principle:

Principle #16Partial or excessive action

3Measurement precision

If user interfaces are generated for confirmation requests, then measurement precision is improved, but device complexity increases

Engineering Contradiction:

Improveaccuracy of event determinationVSAvoidcomplexity of system architecture

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The user interface serves multiple functions: displaying determined event aspects, requesting user confirmation, and receiving corrections. This multi-functional approach improves measurement precision through user verification while avoiding the need for separate dedicated components for each function, thereby limiting the increase in device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Described is a system and method for presenting event information to a user and, if necessary, obtaining confirmation of different aspects (user, item, action) of the event. In some implementations, an event includes a user, an action, and an item. For example, an event may include a user picking an item from an inventory location, a user placing an item into a tote associated with the user, etc. If the aspects of the event cannot be determined with a high enough degree of confidence, a user interface may be generated and sent to the user requesting confirmation of one or more of the aspects of the event.
