Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional weighing scales are placed under the conveyor to measure material weight, then weight measurement capability is achieved, but the system becomes expensive and accuracy remains low
Solution Approach 1:
The patent replaces traditional mechanical weighing scales with a computational system that uses load data from existing conveyor support structures combined with geometric calculations. Instead of relying on expensive load cells positioned under the conveyor belt, the system substitutes mechanical measurement with a combination of simple load sensing at support points and mathematical computation to derive material weight, thereby reducing system cost while improving measurement accuracy
Solution Approach 2:
The patent introduces calculation means as an intermediary between the load determination means and the weight measurement. Rather than directly measuring material weight with scales, the system uses calculation means to process load data from the conveyor supports and compute material weight based on geometric relationships and known constants, serving as a computational mediator that transforms simple load measurements into accurate weight determinations
2Reliability

Solution Approach 2:
The patent makes the conveyor support structures serve multiple functions: they simultaneously support the conveyor belt and provide load measurement data for material weight determination. By integrating the weighing function into the existing structural supports rather than adding separate specialized weighing equipment, the system achieves reliable weight measurement while minimizing additional cost and complexity

AI summary
A conveyor system comprising a conveyor and a conveyor weighing apparatus. The conveyor weighing apparatus has a load determination device for determining the load exerted the conveyor on a conveyor support. The conveyor weighing apparatus may have measurement devices for measuring the angle and speed of the conveyor. The load determination device determines the load exerted by the at least section of conveyor in both laden and unladen states, and the results are combined with the speed and angle measurements, and with known system constants, to calculate the weight of material being conveyed.
