Solution Overview
Problem
Current solutions for accessing and monitoring water distribution from fire hydrants are inefficient, allowing unauthorized use, leading to unaccounted water consumption and loss of revenue, as well as errors in billing and operational challenges due to reliance on energy-consuming devices and manual meter reading.
Innovation Solution
A method and device that utilize geolocation to generate and verify a short activation code for secure access to fire hydrants, integrating a geolocation system, calculator, display, and wireless interface to remotely manage access and consumption, ensuring accurate billing and preventing unauthorized use, while being energy-autonomous through microturbine energy recovery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If geolocation-based activation code is implemented, then access security is improved, but device complexity increases
Solution Approach 1:
The system segments the access control functionality into modular components: geolocation system for position acquisition, calculator for code generation, display for code presentation, wireless interface for communication, and memory for data storage. Each component performs a specific function, making the overall complex system manageable and maintainable while achieving high security through coordinated operation of these segmented modules.
Solution Approach 2:
The access control device is designed with multi-functional capabilities that reduce overall system complexity. The same device components serve multiple purposes: the calculator not only generates activation codes but also decodes response codes; the wireless interface handles both transmitting activation codes and receiving response codes; the display shows both activation and response codes. This universality reduces the need for separate dedicated components for each function.
2Productivity
If remote monitoring and control is implemented, then service management is improved, but energy consumption increases
Solution Approach 1:
The system employs periodic action by generating and transmitting activation codes only when access is required, rather than maintaining continuous communication or monitoring. The geolocation-based code generation occurs periodically at the moment of service activation, and the wireless transmission happens only during the brief window when activation is needed. This periodic operation significantly reduces energy consumption compared to continuous monitoring while maintaining effective remote service management.
Solution Approach 2:
The system enables self-service operation where the access control device autonomously generates activation codes based on its geolocation data without requiring continuous external power or control. The device uses its internal calculator to generate codes from position data, stores them in memory, and transmits them automatically when needed, reducing the need for energy-intensive external monitoring and control systems.
3Measurement precision
If manual meter reading is replaced by automated systems, then billing accuracy is improved, but device complexity increases
Solution Approach 1:
The system replaces the manual mechanical process of meter reading with an automated electronic approach. Instead of physically visiting premises to read water meter indices, the system uses wireless communication to automatically transmit and receive activation codes that encode service usage information. The calculator and memory work together to automatically track and verify water consumption based on activation events, eliminating manual reading errors and improving billing accuracy while the modular architecture keeps device complexity manageable.
4Reliability
If position-based access control is implemented, then unauthorized access prevention is improved, but service activation time increases
Solution Approach 1:
The system performs preliminary action by pre-calculating and storing activation codes in memory based on geolocation data before they are needed. When service activation is requested, the device quickly retrieves the pre-prepared code from memory and transmits it via wireless interface, rather than performing complex calculations in real-time. This preliminary preparation of access codes significantly reduces the time required for service activation while maintaining position-based security verification.

AI summary
A method for activating a service associated with an object includes acquiring a position by a geolocation system of a device rigidly attached to the object; calculating an activation code from the acquired position; displaying the activation code; transmitting the activation code by an electronic mobile terminal including a wireless interface to a remote entity; receiving a response code by the electronic mobile terminal, the response code being generated by the remote entity; acquiring the response code by an input interface of the device; decoding the response code by the device; generating a command for unlocking a service associated with the object rigidly attached to said device.
