Solution Overview

Problem

Customers at a store, such as a restaurant, often cannot determine the number of available servings of a service, leading to potential disappointment when services are unavailable, and existing projection devices do not effectively communicate this information.

Innovation Solution

A projection processing device that acquires the number of available servings and projects notification images on the floor to inform customers about the availability of services, using an image capturing device to adjust the projection based on customer presence and changing image content to reflect availability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If customers line up at the store, then service delivery can occur, but customers may wait in vain when no servings are available

Engineering Contradiction:
Improveservice delivery efficiencyVSAvoidcustomer waiting time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system performs preliminary action by displaying the number of available servings to customers before they reach the counter. This allows customers to make informed decisions about whether to queue, preventing wasted waiting time when services are unavailable while maintaining efficient service delivery when servings are available.

Inventive Principle:
Principle #10Preliminary action

2Loss of information

If the store does not display available servings information, then the system remains simple, but customers cannot grasp service availability

Engineering Contradiction:
Improveservice availability informationVSAvoidprojection system complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The projection display serves as an intermediary between the store's inventory system and customers. It translates internal serving availability data into visible notification images projected on the floor, providing clear information without requiring complex customer-facing interfaces or increasing overall system complexity significantly.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If the projection displays static notification images, then the implementation is simple, but the information does not update when availability changes

Engineering Contradiction:
Improveinformation accuracyVSAvoidprojection control complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system implements feedback by continuously monitoring changes in serving availability and automatically updating the projection display accordingly. When the number of available servings changes, the notification images are dynamically updated to reflect current status, ensuring information accuracy without requiring manual intervention or complex control mechanisms.

Inventive Principle:
Principle #23Feedback

AI summary

Provided are a projection processing device, a storage medium, and a projection method that can realize efficient guidance of customers who receive services. A projection processing device 10 includes a processor 20 that executes projection processing for acquiring a number of available servings of a service and projecting a notification image 50 used to notify information on the number of available servings. Further, the processor 20 is capable of changing display contents of notification images 50 and 51 for each kind of the service, and changing display contents of notification images 50, 50a, and 50b according to the number of available servings.
