Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If electromagnetic measuring devices are positioned along the transport path to measure extensive properties, then measurement speed is improved, but measurement accuracy deteriorates due to interference from transport conveyors and adjacent products
Solution Approach 1:
The patent extracts the product from the interfering transport conveyor environment by using a movable loading element that transfers the product into an isolated internal cavity for measurement. This separation removes the harmful electromagnetic interference from the conveyor and adjacent products while maintaining rapid measurement capability.
Solution Approach 2:
The loading element acts as an intermediary between the transport conveyor and the electromagnetic measuring device. It transfers the product from the noisy external environment into the isolated internal cavity, mediating the conflict between rapid throughput and accurate measurement.
2Measurement precision
If multiple weight measurements are performed using load cells to ensure accurate dosing, then measurement accuracy is improved, but cycle time increases due to multiple pauses
Solution Approach 1:
The patent replaces the mechanical load cell measurement system with an electromagnetic measuring device that operates without physical contact or pauses. The electromagnetic field-based measurement continues while the product moves through the internal cavity, eliminating the need for stopping the transport cycle for multiple weight measurements.
Solution Approach 2:
The electromagnetic measurement process continues uninterrupted as the product moves through the internal cavity along the transport path. This maintains continuous operation of the automatic machine without the multiple pauses required by traditional load cell measurements.
3Adaptability or versatility
If electromagnetic measuring devices are designed to accommodate transport conveyors and adjacent products, then adaptability is improved, but device complexity increases requiring correction algorithms
Solution Approach 1:
The patent extracts the measurement function from the complex environment of transport conveyors and adjacent products by creating an isolated internal cavity. This simplifies the measuring device design by eliminating the need for complex correction algorithms to account for external interferences.
Solution Approach 2:
The measuring device is segmented into distinct functional zones: an external loading area for product reception and an internal isolated cavity for measurement. This segmentation allows the device to maintain adaptability with transport systems while keeping the measurement environment simple and free from interference.
