Solution Overview

Problem

Existing guide apparatuses fail to display routes to multiple destinations in the correct visit order, leading to confusion for facility users who need to visit multiple locations.

Innovation Solution

A guide display control apparatus that includes detection signal obtaining circuitry, schedule obtaining circuitry, next destination specifying circuitry, and display data generating circuitry to determine the next destination in the visit order and generate display data for guiding users to each destination, using approach detectors and a database to track user progress and generate route instructions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a guide apparatus displays only a single route to one destination at a time, then the guidance system remains simple, but facility users cannot efficiently navigate to multiple destinations in a predetermined visit order

Engineering Contradiction:
Improvenavigation efficiencyVSAvoidguide system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The guide display control apparatus dynamically changes the displayed route information based on the user's progress through multiple destinations. The system updates the current destination and route guidance in real-time as the user reaches each location, transforming a static single-route system into a dynamic multi-destination guidance system that maintains clarity while improving navigation efficiency

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The multi-destination route is segmented into individual leg routes, where only the current destination and corresponding route are displayed at any given time. This segmentation prevents information overload by dividing the complete multi-destination journey into manageable sequential segments, allowing the system to handle multiple destinations without proportionally increasing display complexity

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If the guide apparatus tracks user position and provides updated route information, then route accuracy improves, but the system requires more complex detection and control mechanisms

Engineering Contradiction:
Improveuser position detection accuracyVSAvoiddetection system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system implements feedback by detecting when the user reaches each destination and automatically updating the route guidance accordingly. The detection signal from approach detectors feeds back to the guide display control apparatus, which then determines the next destination and updates the displayed route information, creating a closed-loop system that improves position tracking accuracy through continuous feedback without requiring overly complex detection mechanisms

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The guide display control apparatus acts as an intermediary between the simple approach detectors and the display system. It processes detection signals, determines route progress, and generates appropriate display information, thereby enabling accurate position tracking while keeping the detection hardware itself relatively simple by using the control apparatus as a mediating processing layer

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A guide display control apparatus includes: a detection signal obtaining unit to obtain a detection signal including identification information of a facility user who has entered a monitoring area from an approach detector that detects entry of the facility user into the monitoring area; a schedule obtaining unit to obtain a schedule indicating a visit order to a plurality of destinations, the schedule being associated with the identification information included in the detection signal obtained; a next destination specifying unit to specify a next destination in the visit order among destinations that the facility user has not visited yet in the plurality of destinations on the basis of the schedule obtained; and a display data generating unit to search for a route from the monitoring area to the next destination specified by the next destination specifying unit and generate display data for displaying a guide diagram of the route.
