Vehicle Weight-Change Detection for Loading Event Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems require physical scales at loading/off-loading sites to determine the weight of goods, which is time-consuming and expensive for both drivers and site owners, and cannot differentiate the weight of each vehicle during simultaneous loading and off-loading operations.
Innovation Solution
A vehicle-mounted computer system that detects changes in weight while stationary or moving at reduced speed, obtains vehicle data including positioning and time data, and determines loading or off-loading events, eliminating the need for physical scales by identifying the site, load/off-load amount, and associating it with the driver/customer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If physical scales are installed at loading/off-loading sites, then weight measurement capability is provided, but device complexity and maintenance costs increase
Solution Approach 1:
The vehicle's own computer system performs weight change detection and loading event determination autonomously without requiring external weighing infrastructure. The system uses the vehicle's existing sensors and processing capabilities to self-determine loading events, eliminating the need for external physical scales.
Solution Approach 2:
The patent replaces mechanical physical scales with an electronic/digital system based on weight sensor data processing. Instead of using mechanical weighing platforms, the system uses electronic sensors integrated into the vehicle to detect weight changes and determines loading events through computational analysis of this data.
2Measurement precision
If physical scales are used at loading sites, then weight determination is possible, but time consumption increases due to manual operation
Solution Approach 1:
The system continuously monitors weight changes during the loading process without interruption. Weight sensor data is continuously processed to detect loading events in real-time, eliminating the need for manual weighing operations and allowing continuous loading/unloading activities without time loss.
Solution Approach 2:
The vehicle's computer system automatically detects and records loading events without requiring manual intervention. The system self-determines when loading occurs by analyzing weight change data, eliminating the time-consuming manual operation of physical scales.
3Measurement precision
If physical scales are installed at sites, then weight measurement is enabled, but maintenance costs and site expenses increase
Solution Approach 1:
The patent extracts the weight measurement function from the site infrastructure and relocates it to the vehicle itself. By moving the measurement capability from the fixed site location to the mobile vehicle, the site no longer requires expensive physical scales and associated maintenance infrastructure.
Solution Approach 2:
The patent replaces the mechanical physical scales infrastructure at sites with an electronic sensing system integrated into the vehicle. This substitution eliminates the need for site-based weighing equipment and reduces maintenance costs associated with physical scales.
4Measurement precision
If physical scales are used, then total weight is measured, but ability to differentiate individual vehicle weights during simultaneous operations is lost
Solution Approach 1:
The system segments the weight measurement function to operate independently for each vehicle. Each vehicle's computer system processes its own weight sensor data separately, allowing individual weight change detection and loading event determination for multiple vehicles simultaneously without mixing or losing individual vehicle information.
