Solution Overview

Problem

Brick-and-mortar retailers face challenges in balancing product promotion through samples and live demonstrations while protecting inventory from damage, theft, and loss, as existing locking mechanisms restrict consumer interaction and hinder sales service.

Innovation Solution

A system and method for digitally providing access to articles using locking units that can be altered between locked and unlocked states via a digital key stored on a server and provided to a portable electronic device, allowing consumers to access products without payment authorization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional locking mechanisms (cables, RFID tags, locked encasements) are used to secure products, then inventory protection from theft and damage is improved, but consumer ability to access, touch, explore and test products is restricted

Engineering Contradiction:
Improveinventory protectionVSAvoidconsumer product access
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces traditional mechanical locking mechanisms (cables, RFID tags, locked encasements) with a digital locking system. The digital lock receives commands from a mobile device to transition between locked and unlocked states, eliminating the need for physical manipulation of locks by consumers. This substitution maintains security while enabling easier, more flexible product access.

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

Solution Approach 2:

The digital locking system enables consumers to independently unlock and lock products without requiring assistance from sales personnel. The system automatically manages the locking state through digital communication between the lock and consumer's mobile device, allowing self-service product access and eliminating the need for manual intervention.

Inventive Principle:
Principle #25Self-service

2Reliability

If products are secured with locking mechanisms to prevent theft, then inventory security is improved, but sales personnel productivity is reduced due to manual unlocking requirements

Engineering Contradiction:
Improveinventory securityVSAvoidsales personnel service capacity
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The digital locking system transfers the unlocking function from sales personnel to consumers. Consumers use their own mobile devices to communicate unlock commands to the digital lock, eliminating the need for employees to manually intervene in routine product access. This significantly increases employee productivity and allows them to service more customers.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical unlocking operations with automated digital communication. The digital lock receives unlock commands wirelessly from mobile devices, eliminating the need for employees to physically manipulate locks. This automation scales seamlessly to handle high volumes of consumers without requiring additional manual labor.

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

3Reliability

If manual unlocking processes are used, then inventory control is maintained, but consumer wait time increases and service quality decreases

Engineering Contradiction:
Improveinventory controlVSAvoidconsumer wait time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces slow manual unlocking operations with rapid digital communication. The digital lock receives unlock commands instantaneously from mobile devices, reducing the time required to access products from minutes to seconds. This eliminates consumer wait time while maintaining inventory control through continuous digital monitoring.

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

Solution Approach 2:

The system performs preliminary authentication and authorization actions before the consumer actually needs to access the product. The digital lock is pre-configured with security protocols and communication channels, so when a consumer presents their mobile device, the unlock process can begin immediately without requiring preliminary manual intervention or time-consuming verification procedures.

Inventive Principle:
Principle #10Preliminary action

AI summary

In one embodiment, a system for digitally providing access to one or more articles is disclosed. The system includes one or more locking units to secure the articles in a locked state. A server generates or stores a digital key associated with the article or the locking unit. When the digital key is provided to a portable electronic device of a user, the digital key enables the portable electronic device to alter the locking unit between the locked state and the unlocked state without the user paying for the article or authorizing payment for the article. Upon a first event, the digital key is assigned to the user and provided to the portable electronic device of the user. The first event includes the user initiating a request for access to the article or the digital key, and verification that the user satisfies a predetermined condition.
