Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional load hauling trailers and wagons face issues in accurately measuring peak weights due to dynamic forces during movement, leading to excessive warranty repairs and misuse of vehicles not suited for their intended loads.
Innovation Solution
A peak weight detection system using a load cell and processor that compares weight signals to determine if the current load exceeds the stored peak weight, with a verification process involving a second signal to filter out momentary spikes and ensure accurate recording of peak loads, including secure storage and date stamping for analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a load cell is used to measure weight in a moving wagon, then weight information is available, but the measurement precision deteriorates due to dynamic forces during movement
Solution Approach 1:
The system performs preliminary action by capturing and storing potential peak weight signals during movement, then verifying them against predetermined criteria (thresholds, duration, rate of change) before final confirmation. This allows the system to prepare for accurate peak detection in advance while filtering out false signals from dynamic forces.
Solution Approach 2:
The system uses feedback by continuously monitoring weight signals and comparing them against stored peak values and predetermined criteria. When a potential peak is detected, the system feedback-loops to verify the signal meets all criteria before updating the stored peak, ensuring reliable differentiation between actual overloading and dynamic force variations.
2Loss of information
If conventional load cells are used without verification, then weight signals are captured, but the loss of information occurs due to inability to distinguish between dynamic forces and actual weight changes
Solution Approach 1:
The system establishes predetermined criteria (thresholds, duration requirements, rate of change limits) in advance before weight measurement begins. This preliminary configuration allows the system to automatically filter false signals without requiring complex real-time analysis, reducing information loss while maintaining manageable system complexity.
Solution Approach 2:
The feedback mechanism compares each captured weight signal against the predetermined criteria and stored peak values. This automated verification process prevents loss of information about actual peak weights by systematically distinguishing true peaks from dynamic force artifacts, while keeping the system relatively simple through rule-based decision logic.
3Adaptability or versatility
If the wagon is designed with complex mixing and distribution features, then the wagon can perform multiple functions, but the ease of operation deteriorates leading to increased warranty repairs
Solution Approach 1:
The weight detection system performs self-service by automatically monitoring, analyzing, and recording peak weight events without requiring operator intervention. The system autonomously differentiates between dynamic forces and actual overloading, providing reliable information that helps operators understand whether failures are due to misuse or design issues, thereby easing operation of complex multi-functional wagons.

AI summary
A peak weight detecting system and method which analyzes signals generated by a load cell indicating a load within a container. The signal indicates a weight which is compared with a stored peak weight. If the new weight exceeds the stored weight, the new weight is verified by comparison to a weight indicated by a second signal from the load cell. If the weights indicated by the first and second signals are within a specified percentage of each other, the weight indicated by the first signal may displace the stored peak weight and may be stored as a new peak weight.
