Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions for networking measurement instruments, such as those in aerosol and air quality metrology, are costly, unreliable, and require high maintenance due to the need for complex software and hardware infrastructure, making it difficult to integrate and manage multiple devices and communication protocols.
Innovation Solution
A universal communication system featuring a remote server with a thin client platform and gateways that support bidirectional communication with measurement instruments, using various protocols and internet connections to centralize data access and maintenance, reducing the need for local infrastructure and enabling remote updates and monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fat client architecture with computers equipped with communication cards and complex software is used to interconnect measurement devices, then all communication protocols can be incorporated on said computers, but the high cost of the infrastructure and high maintenance requirements are generated
Solution Approach 1:
A gateway is introduced as an intermediary device between measurement instruments and computers. The gateway handles all protocol conversions and communication tasks, allowing computers to access data from diverse measurement devices without needing complex local software configurations. This mediator approach resolves the contradiction by centralizing complexity in a dedicated gateway rather than distributing it across multiple computers.
Solution Approach 2:
The gateway is designed with universal functionality to communicate with multiple types of measurement instruments through various protocols simultaneously. This single multi-functional device replaces the need for multiple specialized computers, reducing overall infrastructure complexity while maintaining broad protocol compatibility.
2Reliability
If fat client architecture with local software and communication protocols on each computer is used, then measurement devices can be connected, but reliability is limited by the hardware architecture and maintenance requirements increase
Solution Approach 1:
The gateway serves as a centralized intermediary that manages all communication protocols and data processing. This centralization improves reliability by eliminating the need for complex distributed software on multiple computers, and simplifies maintenance as issues can be resolved at the gateway level rather than requiring updates across numerous client computers.
Solution Approach 2:
Complex communication software and protocols are extracted from individual computers and consolidated into a dedicated gateway device. This extraction improves reliability by removing software complexity from the client computers and simplifies maintenance by concentrating all protocol management in a single accessible location.
3Adaptability or versatility
If each measurement instrument is associated with a computer and local updates are required on each station, then communication with measurement devices is established, but adding a new sensor requires local update on each connected station
Solution Approach 1:
The gateway acts as an intermediary that receives new sensors and handles all necessary protocol configurations and integrations centrally. When a new sensor is added, only the gateway needs to be updated with the appropriate communication parameters, rather than requiring updates across all connected computers. This mediator approach significantly reduces the time and complexity of adding new sensors to the network.
