Innovation Solution
The integration of autonomous mobile robots equipped with various sensors and a controller, part of an IoT system, that can autonomously perform inspections and maintenance tasks, including calling elevator cars and collecting sensor data, analyze the data, and communicate with a central system for further actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If human personnel perform elevator inspections and maintenance, then maintenance quality can be ensured through human judgment, but safety risks increase and efficiency decreases due to manual operations in hard-to-reach locations
Solution Approach 1:
The system enables self-service maintenance through autonomous robots that perform inspections and maintenance tasks independently. The robot navigates elevator shafts, positions itself at required heights, and executes maintenance operations without human intervention, eliminating safety risks while maintaining reliability through automated sensor-based detection and actuation.
Solution Approach 2:
Manual mechanical inspection methods are replaced with automated sensor systems. The robot uses optical sensors, LIDAR, cameras, and other detection devices to identify maintenance needs, replacing human visual and tactile inspection. Actuation systems then perform maintenance operations automatically, substituting human mechanical actions with controlled robotic movements.
2Adaptability or versatility
If human personnel perform elevator inspections manually, then flexibility in handling complex issues can be maintained, but productivity decreases due to time-consuming manual operations
Solution Approach 1:
The robotic system incorporates dynamic adaptability through real-time sensor data processing and automated decision-making algorithms. The robot can adjust its inspection path, select different sensor modalities, and modify maintenance operations based on detected conditions, providing flexibility comparable to human judgment while operating at robotic speeds and efficiencies.
Solution Approach 2:
The system implements continuous feedback loops where sensor data from cameras, LIDAR, and other detectors is processed in real-time to guide robot navigation and maintenance operations. This feedback mechanism enables the robot to adapt to complex situations dynamically, identifying issues and adjusting operations based on actual conditions observed during inspection.
3Measurement precision
If comprehensive sensor assemblies are installed on the robot, then measurement precision improves for detecting elevator issues, but device complexity increases
Solution Approach 1:
The robotic platform is designed as a universal system that integrates multiple sensor types (optical, LIDAR, cameras, acoustic, temperature) and maintenance functions into a single multifunctional unit. This multi-functionality allows the same robot to perform various inspection tasks and maintenance operations across different elevator models and locations, justifying the complexity through broad applicability and reduced need for multiple specialized systems.

AI summary
Building systems and methods of performing building maintenance operations are described. The systems include a controller configured to receive requests associated with an elevator system of a building. A database having verification procedures associated with the elevator system is provided and the controller is operable to initiate the verification procedures. A robot is configured in communication with the controller and configured to receive instructions from the controller. The instructions may include a portion of a verification procedure, wherein the robot is configured to perform one or more tasks based on the verification procedure. The robot includes at least one sensor configured to collect sensor data. At least one of the controller and the robot are configured to perform an operation in response to sensor data collected by the robot, with the operation being a determination if the elevator system operation is nominal or if further action is required.
