HVAC Service Log Database with Dynamic Maintenance Procedure Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing HVAC system databases lack sufficient information to address specific operating conditions, leading to inefficient and costly servicing processes, as users often need to contact OEMs or rely on prior knowledge for troubleshooting, and updates to the database are not dynamically shared among users.
Innovation Solution
A database system that allows users to dynamically update and share service logs, including active operating data, conditions, and maintenance procedures, enabling efficient data management and retrieval through a computing device, facilitating the completion of services by providing readily accessible and relevant information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a database stores basic manufacturer's guide information for HVAC servicing, then the information is readily accessible, but the information is insufficient to complete certain services
Solution Approach 1:
The database is segmented into multiple hierarchical levels: manufacturer's guide information, service logs from similar systems, and dynamically generated service procedures. Each segment contributes specific information needed for complete servicing, allowing the system to provide comprehensive guidance without requiring a single overly complex database structure.
Solution Approach 2:
The patent adds temporal and contextual dimensions to the database by incorporating service logs from similar HVAC systems over time. This transforms the static manufacturer's guide into a dynamic information system that evolves with accumulated service experience, providing dimensionally richer information without increasing structural complexity.
2Ease of operation
If service logs are updated in real-time, then data accessibility improves, but data management complexity increases
Solution Approach 1:
The system enables self-service data updates where technicians automatically contribute service log information during normal servicing operations. The database updates itself through routine service activities without requiring complex centralized management, improving accessibility while keeping management complexity minimal.
Solution Approach 2:
The system implements feedback mechanisms where service outcomes automatically update the database, which then feeds improved information back to future service operations. This closed-loop feedback system maintains data accessibility while managing complexity through automated feedback processing rather than manual management.
3Reliability
If technicians rely on prior knowledge and OEM contact for troubleshooting, then service accuracy may be maintained, but service time and costs increase
Solution Approach 1:
The database pre-contains service logs and procedures from similar HVAC service scenarios, allowing technicians to access proven solutions before encountering problems. This preliminary preparation of information enables accurate troubleshooting without requiring time-consuming OEM contact or reliance on individual technician memory.
Solution Approach 2:
The database serves multiple functions: it provides manufacturer's guide information, stores service logs from similar systems, generates updated service procedures, and enables knowledge sharing across the industry. This multi-functionality maintains service accuracy through comprehensive information while reducing time losses by consolidating multiple information needs into a single universal system.
Data Source
AI summary
A tangible, non-transitory, machine-readable medium includes instructions that, when executed by a processor, cause the processor to determine an active operating condition of the heating, ventilation, and/or air conditioning (HVAC) system based on the active operating data related to the HVAC system, retrieve an existing service log having a maintenance procedure corresponding to the active operating condition of the HVAC system, and record an entry service log. The entry service log includes the active operating data, the active operating condition, and an updated version of the maintenance procedure corresponding to the active operating condition.
