Fluid Dispensing Meter Authorization via NFC
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fluid dispensing systems require users to manually enter PIN codes and scroll through lists of work orders, making the authorization process cumbersome and time-consuming for fluid dispensing in vehicle fleet management systems.
Innovation Solution
A fluid dispensing meter equipped with a trigger control mechanism, data receiver, and control board that uses user-identification data from an external source to automatically authorize fluid dispensing, eliminating the need for manual PIN entry by using NFC or optical scanners to identify authorized users and associate them with work orders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual PIN code entry and work order selection are required, then user authorization control is maintained, but the authorization process becomes cumbersome and time-consuming
Solution Approach 1:
User identification data is captured in advance through NFC cards, optical scanners, or other data sources before the dispensing action is required. This preliminary capture of identification information eliminates the need for manual PIN entry at the moment of dispensing, thereby streamlining the authorization process and reducing time loss.
Solution Approach 2:
The manual mechanical process of typing PIN codes and scrolling through work order lists is replaced with automated electronic data capture methods such as NFC card readers and optical scanners. This substitution eliminates manual interaction and significantly reduces the time required for authorization.
2Productivity
If automated user identification is implemented, then authorization speed is improved, but system complexity increases
Solution Approach 1:
The fluid dispensing meter is designed to perform multiple functions: it can read NFC cards, process optical scanner data, store user identification information, validate authorization, and control the trigger mechanism. By integrating these diverse functions into a single multi-functional device, the system achieves high productivity without requiring separate specialized devices for each function.
Solution Approach 2:
A control board with a processor acts as an intermediary between various data sources (NFC cards, optical scanners) and the trigger control mechanism. This intermediary component centralizes the processing logic, managing user identification data and authorization decisions, thereby coordinating the complex interactions between different system components.
3Reliability
If user identification data is stored and compared in memory, then unauthorized dispensing is prevented, but data processing requirements increase
Solution Approach 1:
User identification data is captured and stored in memory in advance, before the dispensing operation occurs. This preliminary storage allows the processor to perform simple comparison operations during authorization rather than complex real-time processing, thereby maintaining security while reducing energy consumption during the actual dispensing action.
Data Source
AI summary
A fluid management system includes an authentication device and a fluid dispensing meter, and the fluid dispensing meter includes a processor and a memory. The authentication device is configured to provide user-identification data to the processor. The processor is configured to recall approved user identities from the memory, to compare the approved user identities to the user-identification data received from the authenticator, and to control a trigger control mechanism between the activated state and the deactivated state based on the comparison of the user-identification data and the approved user identities.
