Tire Module Direct Internet Data Transfer via LPWAN
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tire sensors require a central receiving unit in the vehicle for data evaluation and transmission, which is inconvenient and inefficient, especially for fleet management, as it necessitates additional hardware and software for data processing and display.
Innovation Solution
A method where tire modules connect directly to a central Internet server via a low-energy wide-area network, allowing data transmission and evaluation without the need for a central unit in the vehicle, enabling data access through a web portal or app, with data transmitted via narrow-band IoT connections and displayed on mobile devices or web portals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a central receiving unit is installed in the vehicle to process and display tire sensor data, then data evaluation and display are enabled, but additional hardware and software complexity is introduced
Solution Approach 1:
The patent extracts the data processing function from the vehicle and relocates it to a centralized server on the internet. The tire sensor modules transmit raw data directly to the server, which performs all evaluation and stores results. This eliminates the need for complex receiving units, processors, and display systems in each vehicle, while still providing comprehensive data analysis capabilities through web portals and mobile applications.
2Reliability
If tire sensors transmit data continuously to ensure real-time monitoring, then monitoring accuracy is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic data transmission where tire sensor modules send measurements at predetermined time intervals rather than continuously. The server receives these periodic updates and maintains current knowledge of tire conditions. This approach ensures reliable monitoring while significantly reducing energy consumption compared to continuous transmission, as the sensors can enter low-power states between measurement cycles.
3Adaptability or versatility
If additional processing units are installed in each vehicle for fleet management, then fleet-wide tire monitoring is enabled, but system complexity and cost increase
Solution Approach 1:
The patent creates a universal centralized server system that serves multiple functions: it processes data from individual vehicles, provides fleet-wide monitoring capabilities, generates maintenance schedules, and supports multiple users through web portals and mobile apps. This single multi-functional server replaces the need for separate processing units in each vehicle, enabling fleet management capabilities while reducing overall system complexity and cost.
