Solution Overview
Problem
Maintenance service providers face challenges in efficiently managing assets and monitoring performance indicators for site maintenance operations, particularly in indoor locations, due to a lack of precise location-specific performance data and correlation with maintenance site locations.
Innovation Solution
A system comprising a maintenance device equipped with motion sensors and localization sensors that can be tracked on an indoor map, allowing for the characterization and display of movement, and an offsite computer to determine if a site maintenance operation has been completed by comparing measured parameters to predetermined benchmarks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional maintenance monitoring methods are used, then device complexity is reduced, but measurement precision of performance data deteriorates
Solution Approach 1:
The monitoring system is segmented into multiple independent sensor modules (motion sensors, localization sensors, depth sensors) distributed across maintenance devices. Each sensor captures specific performance parameters independently, and data is aggregated centrally to achieve comprehensive high-precision measurement without requiring a single complex monitoring system.
Solution Approach 2:
A centralized server or cloud platform acts as an intermediary to receive, process, and analyze data from multiple simple sensors on maintenance devices. This intermediary handles the complex data fusion and performance evaluation algorithms, allowing individual devices to remain simple while achieving sophisticated measurement precision through centralized processing.
2Loss of information
If location-specific performance tracking is implemented, then information completeness improves, but device complexity increases
Solution Approach 1:
The maintenance devices are equipped with multi-functional sensor suites that simultaneously capture location data (via localization sensors), motion parameters (via motion sensors), and performance metrics (via depth sensors and other measurement devices). This universal sensing approach eliminates the need for separate specialized systems for each type of data collection.
Solution Approach 2:
The system implements continuous feedback loops where sensor data is constantly monitored, analyzed, and used to adjust maintenance operations in real-time. Performance data is fed back to operators and system controllers, enabling dynamic optimization of maintenance activities based on actual measured conditions rather than static pre-planned procedures.
3Productivity
If real-time motion parameter detection is used, then productivity monitoring improves, but use of energy increases
Solution Approach 1:
Instead of continuous real-time monitoring, the system employs periodic sampling of motion parameters and performance data at strategically determined intervals. Sensors capture data at specific time points or when triggering events occur (e.g., when maintenance operations begin or end), providing sufficient productivity information while allowing sensors to enter low-power states between measurements.
Solution Approach 2:
The system monitors only the critical motion parameters and performance metrics necessary for evaluating maintenance productivity, rather than continuously tracking all possible variables. By focusing on key performance indicators (KPIs) such as area covered, time spent on tasks, and equipment utilization, the system achieves effective productivity monitoring with reduced sensor activity and lower energy consumption.

AI summary
Systems and methods for detecting a site maintenance operation done by a maintenance device are described. At least one motion sensor and at least one localization sensor can each be operatively coupled to the maintenance device to detect one or more motion parameters of the maintenance device via the motion sensor and the localization sensor. The maintenance device can be localized (e.g., its position located) on the indoor map. A movement of the maintenance device can be characterized and/or tracked on the indoor map. A motion map can be displayed to illustrate (e.g., visually represent) the characterized movement. An offsite computer can be used to determine whether the site maintenance operation has commenced at the indoor location, measure one or more maintenance parameters of the site maintenance operation and/or compare the one or more maintenance parameters to predetermined benchmark parameters to determine whether the site maintenance operation has been completed.
