Wireless Handwash Compliance Monitoring System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current handwash compliance monitoring systems face security concerns, high installation costs, and strained customer relationships due to the need for proprietary data protocols and network access, especially when data is transmitted over customer-owned networks or requires expensive wired connections for retro-fit applications.
Innovation Solution
A low-bandwidth wireless communication system using sensors, hubs, and a cellular network to transmit handwash compliance data from handwash dispensers to a remote server, minimizing network infrastructure burden and ensuring secure, cost-effective data transfer with minimal customer network exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is transmitted over a wired network (RS-485) to a central location, then data collection and analysis capability is improved, but installation cost and complexity increase significantly
Solution Approach 1:
The patent replaces the mechanical wired RS-485 network infrastructure with a wireless communication system using wireless transceivers and a cellular network. This substitution eliminates the need for physical cable installation while maintaining data collection and transmission capabilities, directly resolving the contradiction between reliable data collection and installation complexity.
2Object-affected harmful factors
If a proprietary data protocol is used for monitoring, then data security and confidentiality are improved, but customer network exposure and security risks increase
Solution Approach 1:
The patent extracts the proprietary data protocol from the customer's internal network infrastructure and places it within a dedicated wireless monitoring system that communicates through a cellular network. This extraction allows the proprietary protocol to be used for secure data transmission while isolating it from the customer's network, preventing security breaches through the customer's firewall without compromising data confidentiality.
3Reliability
If data cables are installed for retro-fit applications, then data transmission capability is improved, but installation cost increases significantly
Solution Approach 1:
The patent replaces expensive wired data cable installations with a wireless communication system that uses wireless transceivers and cellular network infrastructure. This substitution is particularly beneficial for retro-fit applications where running new cables would be costly and complex, while still providing reliable data transmission capability.
