Solution Overview

Problem

The manual transport of cash cassettes between retail checkout areas and back offices poses a high risk for employees due to long distances and potential criminal threats, as existing autonomous transport solutions lack the necessary security features and operational flexibility.

Innovation Solution

A mobile, autonomous rack system equipped with a navigation unit, transmitting and receiving units, and a control unit that sets timers and activation/deactivation of validation units for secure data transmission and manipulation detection, allowing for fully automated transport between predetermined locations with enhanced security measures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual transport of cash boxes is used, then employees can handle cash boxes flexibly, but employees are exposed to high security risks during transport

Engineering Contradiction:
Improvesecurity riskVSAvoidautomated transport
Core Design Contradiction:
ReliabilityVSExtent of automation

Solution Approach 1:

The mobile rack is equipped with autonomous navigation capabilities, allowing it to transport cash boxes independently without human intervention during the transport phase, thereby eliminating employee exposure to security risks while maintaining operational flexibility

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The mobile rack serves as an intermediary between the checkout area and back office, taking over the transport function from employees and providing a secure, automated platform that reduces human exposure to criminal threats

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If autonomous transport system is implemented, then security risk is reduced, but system complexity increases

Engineering Contradiction:
Improvesecurity riskVSAvoidautonomous system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The mobile rack integrates multiple functions including autonomous navigation, cash box transport, and validation unit control into a single platform, reducing the need for separate systems while maintaining high security standards

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

Solution Approach 2:

The system incorporates validation units that monitor and verify the security status of cash boxes during transport, providing real-time feedback to ensure any tampering is detected and responded to automatically

Inventive Principle:
Principle #23Feedback

3Reliability

If validation units with timers are used, then cash security is enhanced through automatic invalidation, but device complexity increases

Engineering Contradiction:
Improvecash securityVSAvoidvalidation unit
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The validation units are pre-configured with timers that automatically invalidate cash boxes if tampering is detected within a specified time window, eliminating the need for complex real-time decision-making algorithms while maintaining high security

Inventive Principle:
Principle #10Preliminary action
