Mobile Loadage Display Using Wireless In-Vehicle Signal Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional loadage display systems for vehicles require an in-vehicle ECU and power supply, limiting remote monitoring and failing to alert drivers of overloading, which can lead to accidents and road damage.
Innovation Solution
An in-vehicle signal-sending device with a sensor signal collecting unit and in-vehicle communication unit that sends loadage information to a mobile terminal via short-range wireless communication, allowing real-time display and alerting drivers of overloading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional loadage display systems use in-vehicle ECU and power supply, then the system can process and display loadage information, but the system complexity increases and remote monitoring becomes impossible
Solution Approach 1:
The patent extracts the ECU and power supply components from the in-vehicle system, transferring all processing and display functions to the mobile terminal. The in-vehicle device only retains sensor signal collection and wireless transmission capabilities, eliminating the need for complex in-vehicle processing units and power management systems.
Solution Approach 2:
The mobile terminal acts as an intermediary between the loadage sensors and the display function. Instead of direct in-vehicle processing, the mobile terminal receives wireless signals from the in-vehicle sensors and performs all calculation, processing, and display operations externally.
2Device complexity
If loadage information is only displayed on in-vehicle screen, then the display function is simple, but remote monitoring and real-time alerting become impossible
Solution Approach 1:
The patent adds a spatial dimension to the display system by enabling information to be accessed both in-vehicle and remotely via mobile terminals. The loadage information is transmitted wirelessly to the mobile terminal, allowing drivers to monitor loadage on their phones and enabling remote access to loadage data.
Solution Approach 2:
The mobile terminal serves multiple functions: it acts as a remote display device, a real-time monitoring system, an alerting mechanism, and a data storage unit. This multi-functional approach eliminates the need for dedicated in-vehicle display hardware while providing enhanced capabilities.
3Device complexity
If the system only alarms when maximum loading capacity is exceeded, then the alarm function is simple, but early warning of potential safety issues is lost
Solution Approach 1:
The system performs preliminary actions by calculating and displaying loadage information in real-time before overloading occurs. The mobile terminal continuously monitors loadage data and can alert drivers to approaching weight limits, enabling preventive action before safety thresholds are exceeded.
Solution Approach 2:
The system implements continuous feedback by transmitting loadage information to the mobile terminal in real-time. This feedback loop allows drivers to monitor current loadage status and make adjustments before reaching dangerous levels, rather than receiving only post-event alarms.

AI summary
A mobile terminal includes a mobile communication unit for communicating with an in-vehicle signal-sending device, an input operation unit for inputting data, a computational processing unit for performing computational processing, a display unit for displaying a screen, a storage unit for storing screen display information, and a mobile control unit for controlling the display unit. The computational processing unit has a function for calculating a loadage deviation based on vehicle specifications and vehicle loadage information contained in a sensor signal from the mobile communication unit, the storage unit has a function for presetting the vehicle specifications, the loadage deviation, and the screen display information prepared to display the vehicle specifications and the loadage deviation on the display unit screen, and the mobile control unit has a function for causing the display unit to display at least the vehicle specifications and the loadage information based on the screen display information.
