Solution Overview

Problem

Conveyance systems such as elevators, escalators, and moving walkways have limited data collection capabilities due to hardwired sensors, restricting their ability to gather comprehensive data.

Innovation Solution

A robot data collection system that moves around the landing or within the elevator lobby to collect data, including detecting individuals, determining their identities, and transmitting elevator calls to dispatchers, while also detecting fires and other issues to adjust conveyance system operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If hardwired sensors are used in conveyance systems, then the system structure is simple and reliable, but the data collection capability is limited

Engineering Contradiction:
Improvedata collection capabilityVSAvoidsystem structure
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

A mobile robot acts as an intermediary between users and the conveyance system. The robot collects data using its sensors and communicates with the conveyance system controller, enabling enhanced data collection without hardwiring sensors throughout the entire system. This mediator approach allows comprehensive information gathering while maintaining the simplicity of the core conveyance system structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If mobile robots are deployed to collect data, then data collection capability is enhanced, but the system complexity increases

Engineering Contradiction:
Improvedata collection capabilityVSAvoidsystem structure
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The mobile robot performs multiple functions: it collects data using sensors, navigates autonomously, communicates with the conveyance system, and provides user assistance. This multi-functionality consolidates various system components into a single versatile unit, enhancing data collection capability while actually reducing overall system complexity compared to having separate dedicated components for each function.

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

3Adaptability or versatility

If traditional elevator calling systems are used, then the system is simple to operate, but it cannot provide personalized service to robots and co-bots

Engineering Contradiction:
Improvepersonalized service capabilityVSAvoidoperation simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The elevator calling system transitions from a static, fixed interface to a dynamic, adaptive interface. The mobile robot can dynamically adjust its calling behavior based on real-time conditions such as its current location, destination, travel speed, and interaction with users. This dynamic approach enables personalized service for robots and co-bots while maintaining operational simplicity through automated decision-making algorithms.

Inventive Principle:
Principle #15Dynamics

4Adaptability or versatility

If the elevator car waits for the robot at the landing, then the robot's service capability is improved, but the elevator system efficiency may be reduced

Engineering Contradiction:
Improverobot service capabilityVSAvoidelevator system efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The elevator system performs preliminary actions by calculating the robot's estimated time of arrival based on its location, travel speed, and distance to the landing. The elevator car positions itself in advance to arrive simultaneously with the robot, eliminating waiting time. This preliminary calculation and coordinated scheduling enable personalized service for robots while maintaining overall system efficiency through optimized dispatch algorithms.

Inventive Principle:
Principle #10Preliminary action
