Vehicle Weight Change Detection for Scale-Free Loading Events
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, and cannot differentiate the weight of individual vehicles, leading to inefficient billing.
Innovation Solution
A vehicle-mounted computer system that detects changes in weight while stationary or moving at reduced speed, obtains vehicle data, and determines loading or off-loading events, eliminating the need for physical scales by associating weight changes with positioning and time data to identify sites, drivers, and calculate billing information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If physical scales are installed at loading/off-loading sites, then weight measurement is possible, but site maintenance costs increase and billing efficiency decreases
Solution Approach 1:
The weight measurement function is extracted from the stationary site infrastructure and transferred to the moving vehicle. The vehicle's own suspension system and weight sensors perform the measurement, eliminating the need for external scales at the site.
Solution Approach 2:
The vehicle performs its own weight measurement using its integrated suspension system and sensors. The vehicle's suspension components serve dual purposes: maintaining vehicle stability and measuring weight changes during loading/off-loading operations.
2Measurement precision
If physical scales are used at loading sites, then weight can be determined, but the process becomes time-consuming and productivity decreases
Solution Approach 1:
Weight measurement is performed continuously during the vehicle's movement and stationary periods, rather than requiring a separate weighing step. The system continuously monitors weight changes, enabling immediate detection of loading/off-loading events without interrupting operations.
3Measurement precision
If physical scales are installed, then weight measurement is possible, but the ability to differentiate individual vehicle weights is lost
Solution Approach 1:
The weight measurement is segmented by vehicle, with each vehicle having its own dedicated sensors and measurement system. This allows individual tracking of each vehicle's weight changes, enabling precise billing and differentiation of goods transported by each vehicle.
