Solution Overview

Problem

Conventional money dispensing systems face issues with cash shortages when used for multiple purposes, such as cash-out and change dispensing, leading to impeded transactions due to insufficient change reserves.

Innovation Solution

A money dispensing management apparatus that stores inventory quantity information and reserved change quantities, determining if secondary purpose dispensing is possible based on these data, and performing notification control to prevent cash shortages by limiting or promoting dispensing accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If cash is used for cash-out purpose, then cash-out service is provided, but change inventory becomes insufficient and cash settlement is impeded

Engineering Contradiction:

Improvecash-out service capabilityVSAvoidcash settlement reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system performs preliminary determination of dispensability before actual cash dispensing for cash-out. The control unit checks whether the cash to be dispensed for cash-out can be determined as dispensable based on current change inventory and reserved change quantity, preventing future cash settlement issues before they occur.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback control by continuously monitoring change inventory levels and reserved change quantities. When cash-out requests are made, the system feedbacks information about dispensability determination results, and adjusts cash dispensing decisions based on this feedback to maintain reliable cash settlement capability.

Inventive Principle:

Principle #23Feedback

2Reliability

If change inventory is reserved for primary purpose, then cash settlement is ensured, but cash-out service is limited

Engineering Contradiction:

Improvecash settlement reliabilityVSAvoidcash-out service capability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts the allocation of cash between change inventory and cash-out dispensing based on real-time conditions. The control unit determines dispensability by comparing current inventory against reserved quantities and can flexibly manage cash distribution to balance cash settlement reliability with cash-out service capability.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the parameter of reserved change quantity based on operational needs. By adjusting the reserved change quantity parameter, the system can optimize the balance between maintaining sufficient change for cash settlements and providing cash-out services, adapting to different operational scenarios.

Inventive Principle:

Principle #35Parameter changes

3Productivity

If cash dispensing is allowed without restriction, then cash-out service is smooth, but change shortage occurs

Engineering Contradiction:

Improvecash-out service efficiencyVSAvoidchange inventory quantity

Core Design Contradiction:

ProductivityVSQuantity of substance

Solution Approach 1:

The system applies preliminary anti-action by determining dispensability before cash-out dispensing. The control unit assesses whether dispensing cash for cash-out will cause change shortage by comparing against reserved change quantities, and prevents cash-out dispensing that would lead to change inventory insufficiency, thereby counteracting potential harmful effects before they occur.

Inventive Principle:

Principle #9Preliminary anti-action

4Reliability

If cash dispensing is restricted to maintain change reserve, then cash settlement is protected, but cash-out service is impeded

Engineering Contradiction:

Improvecash settlement reliabilityVSAvoidcash-out service efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The system performs preliminary determination of dispensability before restricting cash-out dispensing. By checking whether the requested cash amount can be dispensed without compromising change reserves, the system can proactively inform users of dispensability status and prevent cash-out transactions that would impede future cash settlements, maintaining both reliability and efficiency.

Inventive Principle:

Principle #10Preliminary action

AI summary

The POS register 20 receives a withdrawal amount of cash to be withdrawn (S1), and transmits a withdrawal possibility determination request to a change machine 30 (S2a). The change machine 30 determines whether withdrawal is possible, based on the withdrawal amount in the withdrawal possibility determination request, inventory quantity data, and reserved-for-change quantity data (S2b), and transmits a determination result to the POS register 20 (S2c). When the determination result is “withdrawal impossible”, the POS register 20 notifies that dispensing of money is impossible. When the determination result is “withdrawal possible”, cash is dispensed from the change machine 30 (S9) through notification of a settlement request amount to a debit terminal 70 (S3), reading of a debit card (S4), a settlement request to a management server 100 (S5), reception of settlement permission (S6, S7), and dispensing instruction to the change machine 30 (S8).
