Dosing Device with Access Control for Authorized Chemical Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dosing devices for cleaning and disinfecting solutions in building technology lack safety features to ensure authorized personnel access and proper accounting of working hours, leading to potential misuse and inefficiencies in resource management.
Innovation Solution
Integration of a registration device and access control system within the dosing device, allowing only authorized personnel to operate it, with features for logging on/off, time recording, and communication modules to transmit data for centralized management and payroll accounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a registration device and access control system are integrated into the dosing device, then safety and authorization control are improved, but device complexity increases
Solution Approach 1:
The patent combines the registration device, access control system, time recording, and dosing control into a single integrated dosing device. This merging of previously separate functions into one unified system improves safety through centralized authorization control while managing complexity through functional integration rather than separate distributed systems.
Solution Approach 2:
The dosing device is designed to perform multiple functions: authorization verification, time recording, dosing control, and communication. This multi-functionality approach consolidates what could have been separate devices into one universal system, improving overall safety while the shared infrastructure reduces total system complexity.
2Reliability
If only authorized personnel can operate the dosing device, then safety is improved, but ease of operation decreases
Solution Approach 1:
The system performs preliminary authorization verification through the registration device before allowing operation. By pre-checking authorization status and recording login times before dosing operations begin, the system ensures safety without complicating the actual dosing operation itself—the authorization step is automated and quick.
Solution Approach 2:
The access control system automatically verifies authorization and records time without requiring manual intervention. The device serves itself by automatically checking credentials and managing authorization status, which maintains ease of operation while ensuring only authorized personnel can access dosing functions.
3Productivity
If working hours and dosing processes are accurately tracked, then resource management is improved, but device complexity increases
Solution Approach 1:
The system implements feedback through the communication module that transmits recorded data about working hours and dosing processes to external systems. This automated feedback loop enables accurate resource management tracking while the digital automation of recording and transmission minimizes the operational complexity compared to manual tracking systems.
Solution Approach 2:
The patent replaces manual time recording and dosing tracking with automated electronic recording through the control unit and communication module. This substitution of mechanical/manual processes with electronic automation improves resource management accuracy while the integrated digital system manages complexity more efficiently than separate manual systems.
