Solution Overview

Problem

Customers face inefficiencies in waiting in lines at deli or counter-served establishments, often having to choose between waiting and missing other shopping opportunities or skipping the line, which can result in missed sales for the store.

Innovation Solution

A virtual queuing system using portable computerized devices, such as smartphones or tablets, that communicate with a remote server to manage a customer's place in line, providing estimated waiting times and alerts, allowing pre-ordering, and adjusting based on location and order complexity, enabling customers to maintain their place without physical presence.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If customers wait in physical line at the counter, then they receive service in order, but they lose time and miss other shopping opportunities

Engineering Contradiction:
Improveservice orderVSAvoidwaiting time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent creates a virtual copy of the physical queue system using portable electronic devices. Customers receive digital queue tickets on their smartphones or tablets that replicate the functionality of physical tickets, allowing them to maintain their place in line remotely while continuing to shop elsewhere in the store.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent introduces a virtual queue management system as an intermediary between customers and the counter service. This system uses portable devices as mediators to communicate queue status, estimated wait times, and service notifications to customers, eliminating the need for direct physical presence in the queue.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of time

If customers skip the counter altogether, then they save time, but the store loses potential sales opportunities

Engineering Contradiction:
Improvewaiting timeVSAvoidmissed sales
Core Design Contradiction:
Loss of timeVSLoss of energy

Solution Approach 1:

The patent enables customers to perform preliminary actions by joining the virtual queue before they actually need service. Customers can join the queue, continue shopping, and receive notifications when their queue number is approaching, allowing them to time their arrival at the counter optimally without skipping service entirely.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent creates a dynamic queue system where customers can join, leave, or be bumped from the queue based on their needs and store conditions. The system adapts to customer behavior by allowing flexible participation while maintaining service order, transforming the static physical queue into a flexible virtual system.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If the system provides detailed queue information, then customers can manage their wait better, but the device complexity increases

Engineering Contradiction:
Improvequeue managementVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent implements a self-service virtual queue system where customers independently manage their own queue participation using their personal portable devices. The system automatically provides queue status, estimated wait times, and service notifications without requiring customer intervention, simplifying the user experience while managing complexity on the system side.

Inventive Principle:
Principle #25Self-service

AI summary

A computer-implemented process can be operated for entering and holding a place for a first customer in a queue while the first customer is waiting to be served at a retail store. The process includes, within a computerized processor, establishing a place in the queue for the first customer, wherein the queue operates to establish among a plurality of customers a customer currently being served by a store employee and an order in which other customers of the plurality will be served. The process further includes displaying upon a portable computerized device of the first customer an indication of a status of the first customer within the queue.
