Solution Overview

Problem

In modern retail environments, there is a need to improve customer experience and convenience, as customers often go unanswered during peak hours due to insufficient staff, high turnover rates, and challenges with tasks like maintaining store cleanliness and inventory management, leading to low satisfaction and increased competition from online shopping.

Innovation Solution

A shopping assistance system utilizing motorized transport units controlled by a central computer system to assist customers and workers, including features like item delivery, inventory management, and route optimization, to enhance the shopping experience and operational efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If more employees are hired to assist customers during peak hours, then customer service quality improves, but labor cost increases

Engineering Contradiction:
Improvecustomer service availabilityVSAvoidlabor cost
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The system enables self-service through automated monitoring where the retail system automatically detects item availability status using sensors and cameras, and notifies customers via mobile devices without requiring staff intervention for routine availability checks

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Manual inventory checking by employees is replaced with automated sensing systems including weight sensors, computer vision cameras, and RFID readers that continuously monitor item availability and transmit data to the central processing system

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

2Measurement precision

If manual inventory monitoring is performed frequently, then inventory accuracy improves, but time consumption increases

Engineering Contradiction:
Improveinventory accuracyVSAvoidtime for inventory checks
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The sensing systems operate continuously to monitor item availability in real-time as customers pick up or return items, eliminating the need for periodic manual inventory counts and providing continuous accurate stock information

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

Manual visual inspection and physical counting of inventory by staff is replaced with automated weight sensors on shelves that detect item removal/addition, computer vision systems that track item locations, and RFID readers that monitor stock levels without human intervention

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

3Stability of the object's composition

If employees are deployed to handle routine tasks like cart collection and aisle maintenance, then store organization improves, but time available for customer assistance decreases

Engineering Contradiction:
Improvestore organizationVSAvoidtime for customer assistance
Core Design Contradiction:
Stability of the object's compositionVSLoss of time

Solution Approach 1:

The system automatically detects abandoned carts through sensors and cameras, and notifies staff only when collection is needed, allowing employees to respond to actual organizational needs rather than performing routine manual checks and maintenance tasks

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Sensors and cameras provide real-time feedback on store conditions such as aisle blockages, abandoned carts, and out-of-stock items, enabling employees to respond to actual problems rather than performing predetermined routine tasks

Inventive Principle:
Principle #23Feedback

AI summary

Systems, apparatuses, and methods for determining item availability are provided. A computer implemented method for determining item availability in a shopping space comprising: receiving a request for an item for purchase from a customer, querying an inventory database to determine whether the item for purchase is in stock, in an event that the item for purchase is not in stock according to the inventory database: determining an out of stock response to present to the customer, in an event that the item for purchase is in stock according the inventory database: instructing a motorized transport unit to travel to a display space in the shopping space corresponding to the item for the purchase, determining whether the item is available in the display space based on information captured by one or more sensors of the motorized transport unit, and in an event that the item for purchase is not available in the display space: determining an item unavailable response to present to the customer.
