Solution Overview

Problem

Existing food and beverage provision systems struggle to accurately record the start time of eating or drinking, leading to inaccuracies in billing and customer analysis, especially if staff forget to set the start time correctly.

Innovation Solution

A food and beverage item provision system that includes an entrance accepting unit, a vacant seat processing unit, a seat setting unit, and a start setting unit, which automatically records the eating or drinking start time by associating seat information with customer acceptance or reservation information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the eating and drinking start time is manually set by staff, then the system can record the start time, but human error causes inaccurate recording when staff forget to set it correctly

Engineering Contradiction:
Improveaccuracy of eating start time recordingVSAvoidconsistency of manual operation
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The system performs automatic seat assignment and eating start time recording without requiring manual staff intervention. When a customer is seated, the system automatically associates the acceptance information with seat information and records the eating start time, eliminating human error and ensuring consistent accurate recording.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system pre-configures the association between acceptance information and seat information before the eating process begins. By automatically recording the eating start time at the moment of seat assignment, the system ensures accurate timing is captured before any potential human forgetfulness can occur.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If manual recording methods are used, then staff can set the start time, but this increases the complexity of operational procedures

Engineering Contradiction:
Improvesimplicity of start time settingVSAvoidcomplexity of manual recording system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system automatically handles seat assignment and eating start time recording without requiring staff to manually set times or follow complex procedures. The automated association between acceptance information and seat information simplifies operations while reducing the need for manual intervention.

Inventive Principle:
Principle #25Self-service

3Productivity

If the system waits for manual input to record eating start time, then staff can control the timing, but this causes delays in accurate billing and customer analysis

Engineering Contradiction:
Improvespeed of billing processingVSAvoiddelay in recording eating start time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system records the eating start time automatically at the moment of seat assignment, before the eating process begins. This preliminary automatic recording eliminates delays and enables immediate billing processing and customer analysis without waiting for manual staff input.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system autonomously captures the eating start time without requiring staff intervention, ensuring immediate and accurate recording that enables faster billing and analysis processes.

Inventive Principle:
Principle #25Self-service

AI summary

A system includes: an entrance accepting unit configured to accept a seat-waiting request from a customer and store the request as acceptance information; a vacant seat processing unit configured to set any seat among a plurality of seats that has become vacant, as a vacant seat in association with seat information relating to the seat; a seat setting unit configured to associate the seat-waiting information with seat information relating to a vacant seat in a predetermined order under a predetermined condition when any seat among the seats for customers has been set as the vacant seat by the vacant seat processing unit; and a start setting unit configured to record eating and/or drinking start information that indicates start of eating and/or drinking in association with the seat information upon the acceptance information being associated with the seat information by the seat setting unit.
