Remote contractor system with case management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Building control systems, such as HVAC, security, and lighting systems, often lack proactive maintenance, leading to inefficient operation, increased costs, and potential damage due to reactive maintenance approaches, which can result in discomfort and additional expenses for building owners.
Innovation Solution
A remote contractor system that communicates with multiple client HVAC controllers over a network, allowing for data collection, alert generation, and case management to facilitate more efficient maintenance scheduling and technician assignment, thereby promoting a proactive maintenance approach.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If building control systems are operated until failure with reactive maintenance, then operational simplicity is maintained, but system reliability deteriorates and damage occurs
Solution Approach 1:
The system performs preliminary actions by continuously monitoring HVAC system parameters and detecting potential failures before they occur. The controller analyzes operational data in real-time and generates service alerts when anomalies are detected, enabling preventive maintenance scheduling before actual failures happen.
Solution Approach 2:
The system implements feedback mechanisms where the controller continuously receives operational data from HVAC systems, analyzes it against predefined criteria, and generates feedback in the form of service alerts. This closed-loop feedback enables the system to automatically identify and report issues requiring maintenance attention.
2Productivity
If reactive maintenance approach is used, then maintenance costs are reduced initially, but loss of time and productivity worsen due to unplanned downtime
Solution Approach 1:
The system schedules maintenance activities in advance based on detected anomalies and alert priorities. By identifying issues before they cause failures, the system allows planning of maintenance during convenient time windows, minimizing disruption to building operations and reducing unplanned downtime.
Solution Approach 2:
The system provides self-service capabilities by automatically monitoring HVAC systems, detecting issues, and generating service alerts without requiring constant human intervention. This automated self-monitoring enables early detection and proactive scheduling, improving maintenance efficiency while reducing reactive response times.
3Ease of operation
If multiple HVAC systems are monitored individually, then system reliability is maintained, but device complexity and operational overhead increase
Solution Approach 1:
The controller is designed with multi-functionality to monitor and manage multiple HVAC systems simultaneously. It can handle various alert types, generate different priority levels, and interface with multiple building management systems, providing a universal monitoring solution that reduces operational complexity despite managing diverse systems.
Solution Approach 2:
The system merges multiple monitoring functions into a single integrated controller that consolidates data from various HVAC systems. By combining alert generation, analysis, and service notification functions into one unified platform, the system simplifies operational workflows while maintaining comprehensive monitoring coverage.
Data Source
AI summary
A system that allows a contractor to remotely monitor and/or interact with its customers' building control systems, such as heating, ventilating and air conditioning (HVAC) systems, and analyze information obtained from the building control systems over time. Such a system may help the contractor monitor and diagnosis customer building control systems, setup service calls, achieve better customer relations, create more effective marketing opportunities, as well as other functions. In some cases, the disclosed system may help a contractor pro-actively identify possible issues with its customer's building control systems and may output an alert related to an operation of the customer's building control systems. Within the system, the contractor may able to open a case associated with the customer's building control systems and link related alerts to the case.
