Sales Data Processing Apparatus with Transmission Confirmation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sales data processing apparatuses lack efficient methods for sending aggregated transaction data to terminal devices and providing confirmation of successful data transfer, leading to potential errors and incomplete data reporting.
Innovation Solution
Incorporating a sending control section to transmit sales data to a terminal apparatus and a printing control section to print sending result information, along with a notification system for confirming data receipt, ensuring reliable data transfer and reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If sales data is sent to terminal apparatus without confirmation mechanism, then data transmission speed is improved, but data reliability deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the terminal apparatus sends back sending result information to the sales data processing apparatus, confirming whether the sales data was successfully received. This feedback loop ensures data reliability while maintaining efficient transmission, as the apparatus only prints the sales report when confirmation is received or timeout occurs.
Solution Approach 2:
The patent sets a predetermined timeout period before printing the sales report. This preliminary action ensures that if data transmission fails or is delayed, the system automatically proceeds with printing after the timeout, preventing indefinite waiting while maintaining data integrity through the timeout mechanism.
2Reliability
If sending confirmation mechanism is implemented, then data reliability is improved, but device complexity increases
Solution Approach 1:
The patent extracts the confirmation function into a separate, simple message type called 'sending result information' that is transmitted along with the sales data. This separation keeps the core communication protocol simple while adding reliability through the optional confirmation mechanism, avoiding the need for complex handshake protocols.
Solution Approach 2:
The terminal apparatus automatically sends back the sending result information without requiring additional user intervention or complex protocol negotiations. This self-service approach maintains simplicity while ensuring reliability, as the confirmation is handled automatically as part of the data transmission process.
3Productivity
If sales report is printed immediately without sending confirmation, then operational efficiency is improved, but data integrity deteriorates
Solution Approach 1:
The patent sets a predetermined timeout period that serves as a preliminary action before printing the sales report. If the sending confirmation is not received within this timeout, the system automatically proceeds with printing, ensuring both efficiency (no indefinite waiting) and integrity (timeout-based fallback).
Solution Approach 2:
The system uses feedback from the terminal apparatus to determine whether to print the sales report. When confirmation is received, printing is triggered immediately; when timeout occurs, printing also proceeds. This feedback mechanism ensures data integrity while maintaining operational efficiency through automated decision-making.
Data Source
AI summary
A sales data processing apparatus includes a sending control section and a printing control section. The sending control section performs control to send, to a predetermined terminal apparatus, sales data obtained by aggregating predetermined transaction data. The printing control section performs control to print, together with the sales data, sending result information indicating whether or not the sales data has been sent.
