Mobile Loadage Display for Real-Time Vehicle Overload Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing loadage display systems require an in-vehicle ECU and power supply, microcomputers for correction calculations, and are limited to displaying information on a vehicle's display screen, failing to provide real-time loadage information to a mobile terminal and alerting drivers of overloading, which can lead to accidents and road damage.
Innovation Solution
An in-vehicle signal-sending device collects loadage sensor signals from vehicle wheels and transmits them via short-range communication to a mobile terminal, which processes and displays the information in real-time, including loadage, loading deviation, and alerts the driver of overloading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If loadage information is displayed only on the vehicle's display screen, then the display system is simple, but the driver cannot obtain real-time loadage information remotely and cannot be alerted of overloading conditions
Solution Approach 1:
The patent introduces a mobile terminal (smartphone or tablet) as an intermediary device between the vehicle's loadage sensor and the driver. The mobile terminal receives loadage data via wireless communication and displays it on its screen, enabling remote access to real-time loadage information and overloading alerts without requiring complex modifications to the vehicle's existing display system
Solution Approach 2:
The patent leverages the mobile terminal's existing display screen and communication capabilities for multiple purposes: displaying real-time loadage information, showing overloading alerts, and providing remote monitoring functionality. This multi-functional approach eliminates the need for dedicated display hardware in the vehicle, reducing system complexity while improving information accessibility
2Ease of operation
If an in-vehicle ECU and power supply are used to control the loadage display device, then the display can be controlled within the vehicle, but the system requires additional in-vehicle components and wiring
Solution Approach 1:
The patent enables the mobile terminal to independently control and display loadage information without requiring an in-vehicle ECU or dedicated power supply connection. The mobile terminal uses its own processing power, display screen, and battery, eliminating the need for additional in-vehicle control components and reducing wiring complexity while maintaining full display functionality
Solution Approach 2:
The mobile terminal acts as an external intermediary that receives loadage data wirelessly and handles all processing and display functions externally, removing the need for in-vehicle control units and power supply connections while maintaining ease of operation through the mobile device's existing interface and display capabilities
3Measurement precision
If a microcomputer is used for correction calculations with offset adjustment values and gain values, then measurement precision is improved, but the device complexity increases
Solution Approach 1:
The patent utilizes the mobile terminal's existing microprocessor and computational resources to perform correction calculations, offset adjustments, and gain value applications. This approach achieves precise loadage measurement without requiring a separate in-vehicle microcomputer, as the mobile terminal's processing capabilities are leveraged to handle all computational requirements
Solution Approach 2:
The mobile terminal's microprocessor is used for multiple functions including running the loadage measurement application, performing correction calculations, applying offset and gain values, and displaying results. This multi-functional use of the mobile terminal's processing unit achieves precise measurements without adding dedicated microcomputer hardware to the vehicle
