Solution Overview

Problem

In large buildings with distributed elevator banks, users often face challenges in locating these banks, especially in crowded or unfamiliar environments, leading to confusion and discomfort.

Innovation Solution

A system and method utilizing drones to communicate directions to elevator banks by displaying indicia on electronic display panels, which can include directional symbols and text, and using radio-navigation systems for tracking and collision avoidance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If floor and wall markers are used to indicate elevator locations, then users can find elevators in clear conditions, but users experience confusion and discomfort in crowded or unfamiliar environments

Engineering Contradiction:
Improveelevator location indication reliabilityVSAvoiduser navigation ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent transitions from two-dimensional floor and wall markers to three-dimensional aerial drones that float above the environment. This dimensional change allows the directional indicators to be visible from a distance and not obscured by crowd density, solving the problem of unreliable indication in crowded spaces.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent introduces drones as intermediary carriers that display directional information. Instead of users directly reading floor/wall markers, the drones act as mobile intermediaries that float ahead of users and provide continuous directional guidance through display panels on their bodies.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If drones display directional indicia on electronic panels, then users can easily locate elevator banks, but the system complexity increases

Engineering Contradiction:
Improveuser navigation easeVSAvoidnavigation system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The drones are equipped with autonomous navigation capabilities including radio-navigation systems and sensor data processing for collision avoidance. This self-service functionality reduces the need for complex external control systems while maintaining ease of use for users.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The drones serve multiple functions: they provide directional guidance to elevator banks, display advertisements on their electronic panels, and navigate autonomously using integrated radio-navigation and sensor systems. This multi-functionality consolidates what would otherwise require separate systems into a single versatile platform.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Measurement precision

If multiple drones are used to guide users through intermediate locations, then navigation accuracy improves, but the quantity of drones and system complexity increase

Engineering Contradiction:
Improvenavigation accuracyVSAvoidnumber of drones
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent divides the navigation task into segments by deploying multiple drones at different locations (first drone at first location, second drone at third location). Each drone handles a specific segment of the journey, providing continuous guidance through intermediate locations like elevator banks, which improves overall navigation accuracy.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically assigns and coordinates multiple drones based on user location and destination. The drones can operate independently or in coordination, with their数量和positions adjusted dynamically to provide optimal guidance coverage without requiring a fixed large fleet.

Inventive Principle:
Principle #15Dynamics

AI summary

Disclosed is a method of communicating directions to an end destination (135) by one or more drones (140), the method having steps of moving via flying motion by a first drone (140A) between a first location (212A) and a second location (212B) along a travel path (210) therebetween, wherein the second location is the end destination or an intermediate location (130); and displaying indicia (230) on a first display panel (220) of the drone that is indicative of directions to the second location.
