Solution Overview

Problem

Existing sales-data processing systems risk executing processing unsuited to the situation, leading to errors and inefficiencies, as they lack mechanisms to ensure that settlement and sending processes are properly synchronized and prohibited when necessary.

Innovation Solution

A sales-data processing device equipped with registration, settlement, and sending means, along with prohibition circuits that prevent execution of settlement or sending processes unless certain conditions are met, such as the presence of a deposit in a change machine or selection of a valid transaction type, ensuring that processing is suited to the situation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the system allows both settlement processing and sending processing to be executable at any time, then the system maintains high flexibility and adaptability, but the risk of erroneously executing processing unsuited to the situation increases

Engineering Contradiction:

Improveprocessing flexibilityVSAvoidexecution accuracy

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The prohibition means is configured to prohibit execution of settlement processing before sending processing is executed. This preliminary prohibition ensures that registration data is always sent to another sales-data processing device before local settlement processing occurs, preventing erroneous execution of settlement processing when sending is required and maintaining reliable data synchronization across the system.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If the system prohibits settlement processing before sending processing is executed, then execution accuracy is improved, but processing time and system complexity increase

Engineering Contradiction:

Improveexecution accuracyVSAvoidprocessing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system executes sending processing as a preliminary step before settlement processing is permitted. The prohibition means automatically lifts the prohibition once sending processing is completed, allowing settlement processing to proceed immediately afterward. This sequential arrangement ensures execution accuracy while minimizing time loss through automatic transition between processing states.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The prohibition means monitors the execution status of sending processing and provides feedback control by automatically lifting the prohibition on settlement processing once sending is complete. This feedback mechanism ensures that settlement processing is only permitted when appropriate conditions are met, maintaining execution accuracy without requiring manual intervention or complex timing control.

Inventive Principle:

Principle #23Feedback

3Reliability

If the system adds prohibition means to control processing execution, then execution accuracy is improved, but device complexity increases

Engineering Contradiction:

Improveexecution accuracyVSAvoidsystem structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The prohibition means acts as an intermediary control element between the sending processing means and settlement processing means. It mediates the execution permission by prohibiting settlement processing until sending processing is complete, then automatically permitting it afterward. This intermediary approach simplifies the overall system structure compared to implementing complex interlocking logic or multiple control layers, as the prohibition means handles all control decisions in a single dedicated component.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A sales-data processing device includes: a registering circuit that registers a product and generates registration data; a settlement processing circuit that executes settlement processing using the registration data; a sending circuit that sends the registration data to another sales-data processing device for execution of the settlement processing by the other sales-data processing device using the registration data; and a prohibiting circuit. Once the sales-data processing device has determined that the sending circuit will send the registration data, the prohibiting circuit prohibits the settlement processing circuit from executing the settlement processing before the sending circuit sends the registration data.
