Problem

The current use of cash in business transactions poses a significant risk of bacterial, viral, and germ transmission due to its handling by multiple individuals, necessitating effective sanitization or sterilization methods.

Innovation Solution

A cash sanitization device that utilizes ultraviolet-C (UV-C) light to sanitize cash paper bills, capable of processing multiple bills per minute and designed for compact integration into existing cash handling systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If cash is handled by multiple individuals for business transactions, then transaction flexibility and liquidity are improved, but bacterial, viral, and germ transmission increases

Engineering Contradiction:

Improvetransaction flexibilityVSAvoidbacterial, viral, and germ transmission

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies preliminary action by sanitizing cash paper bills before they are handled by multiple individuals. The UV-C LED illumination system activates prior to bill handling, pre-sanitizing the surface to reduce pathogen transmission risk during subsequent transactions.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent converts the harmful effect of UV-C light (which can be damaging to materials) into a beneficial sanitization process. The UV-C LEDs illuminate and sanitize the cash bills, transforming a potentially harmful radiation into a protective measure against pathogens.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

2Object-affected harmful factors

If traditional cleaning methods are used on cash paper bills, then sanitization is achieved, but processing speed and productivity are reduced

Engineering Contradiction:

Improvebacteria, viruses, and germsVSAvoidprocessing speed

Core Design Contradiction:

Object-affected harmful factorsVSProductivity

Solution Approach 1:

The patent replaces traditional mechanical cleaning methods with optical/UV-C illumination. Instead of physically cleaning bills through mechanical means, the system uses UV-C LED light to sanitize the surfaces, enabling faster processing without compromising sanitization effectiveness.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the sanitization parameter from mechanical contact-based cleaning to optical UV-C illumination. This parameter change allows for rapid sanitization of multiple bills sequentially, significantly improving processing speed while maintaining effective pathogen reduction.

Inventive Principle:

Principle #35Parameter changes

3Object-affected harmful factors

If comprehensive sanitization systems are implemented, then pathogen reduction is improved, but device complexity and integration difficulty increase

Engineering Contradiction:

Improvepathogen presenceVSAvoidsystem integration complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent applies universality by designing a multi-functional system where UV-C LEDs serve both illumination and sanitization purposes. The same light source provides visibility for handling cash while simultaneously acting as a sanitization mechanism, reducing the need for separate systems and simplifying integration.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system employs self-service principles through automatic UV-C activation upon bill insertion. The sanitization process occurs automatically without requiring manual intervention or complex control mechanisms, simplifying the overall system design while maintaining effective pathogen reduction.

Inventive Principle:

Principle #25Self-service
