Solution Overview

Problem

The existing physical seals on cash boxes are irreversibly destroyed when opened, requiring frequent replacement, leading to high costs and laborious adhesive residue removal, making them inefficient and costly.

Innovation Solution

A device with a sensor and display unit that detects unauthorized opening of the cash box cover, replacing the physical seal with an electronic seal that can be reused, eliminating the need for frequent replacements and simplifying handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a physical seal is used to indicate opening of the cover, then the seal can be easily applied and understood, but the seal must be replaced frequently and adhesive residue removal is laborious

Engineering Contradiction:
Improveease of seal application and understandingVSAvoidtime for seal replacement and residue removal
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent replaces the mechanical/physical seal system with an electronic sensor and display system. The sensor detects cover opening and the display unit visually indicates seal breach, eliminating the need for physical seal application, removal, and adhesive cleaning operations.

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

Solution Approach 2:

The patent creates an electronic copy or representation of the physical seal function. Instead of using actual physical seal material that degrades, the system uses a sensor-display mechanism that replicates the seal's monitoring function indefinitely without material degradation.

Inventive Principle:
Principle #26Copying

2Reliability

If a physical seal is used to indicate opening of the cover, then the seal provides clear indication of unauthorized opening, but high costs are incurred due to frequent replacement

Engineering Contradiction:
Improvereliability of seal indicationVSAvoidcost of seal replacement
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent substitutes the consumable physical seal with a durable electronic sensing and display system. The sensor and display unit can be manufactured once and reused indefinitely, eliminating repeated purchasing and installation costs associated with physical seals.

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

Solution Approach 2:

The patent eliminates the need to discard and replace physical seals by using a reusable electronic system. The sensor and display components are designed to last indefinitely without degradation, recovering the value of the sealing function across multiple use cycles.

Inventive Principle:
Principle #34Discarding and recovering

3Reliability

If a physical seal is applied to the cash box cover, then unauthorized opening can be detected, but a great deal of effort is required for seal removal and reapplication

Engineering Contradiction:
Improvedetection of unauthorized openingVSAvoideffort for seal removal and reapplication
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the manual seal application and removal process with an automated electronic detection system. The sensor automatically detects cover opening and the display unit automatically indicates seal breach, eliminating manual intervention in seal management.

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

Solution Approach 2:

The electronic seal system is self-sufficient, automatically detecting and indicating seal breach without requiring human intervention for application, removal, or reapplication. The system serves itself by using the sensor-display mechanism to monitor and communicate seal status continuously.

Inventive Principle:
Principle #25Self-service

AI summary

The invention relates to a device (10, 30, 40, 50) which is intended for accommodating notes of value and comprises a basic body (12) and a lid (14) for closing and opening of the basic body (12). A further aspect of the invention relates to a device (60) for indicating opening of a lid (14) which closes an opening of a basic body (12) of a cash cassette (10, 30, 40, 50, 80). Both devices (10, 30, 40, 50, 60) comprise a sensor (16, 64), detecting opening of the lid (14), and a display unit (18). The devices (10, 30, 40, 50, 60) also have a control unit (20) which, at least when the sensor (16, 64) has detected unauthorized opening of the lid (14), activates the display unit (18) such that the display unit (18) displays information regarding the opening of the lid (14).
