Solution Overview
Problem
Weighing systems face accuracy issues due to vibrations and movements when conveying items from a receiving section to an outlet section, affecting the precision of the weighing process.
Innovation Solution
A weighing system with a container connected to a conveyor via primary and secondary connecting means, allowing rotation about axes parallel and transverse to the conveying direction, minimizing interference from conveyor movements and vibrations, and utilizing a tertiary connecting means for power and movement transfer, enabling accurate weighing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the container is rigidly fixed to the conveyor means, then the conveyor can efficiently transfer power and movement, but the container is subjected to vibrations and movements that decrease weighing accuracy
Solution Approach 1:
The connecting means is divided into three sections: first section permanently connected to container, second section permanently connected to conveyor, and third section hingedly connected to both. This segmentation allows different parts to perform different functions - the first and second sections provide stable connections while the third hinged section acts as a vibration isolator, resolving the contradiction between efficient power transfer and vibration reduction for accurate weighing
Solution Approach 2:
The hinged third section serves as an intermediary element between the container and conveyor means. It mediates the connection by allowing relative movement and absorbing vibrations, enabling the container to be conveyed efficiently while isolating it from conveyor vibrations during the weighing process
2Device complexity
If the container is rigidly fixed to the conveyor means, then the structure is simple, but the container is subjected to vibrations and movements that decrease weighing accuracy
Solution Approach 1:
The connecting means is divided into three sections: first section permanently connected to container, second section permanently connected to conveyor, and third section hingedly connected to both. This segmentation allows different parts to perform different functions - the first and second sections provide stable connections while the third hinged section acts as a vibration isolator, resolving the contradiction between efficient power transfer and vibration reduction for accurate weighing
Solution Approach 2:
The connection parameters are changed from rigid fixed connection to hinged connection with rotational degrees of freedom. The hinged third section allows the container to rotate slightly about axes parallel and transverse to the conveying direction, changing the mechanical parameters of the connection to reduce vibration transmission while maintaining structural integrity
3Measurement precision
If hinged connecting means are used to reduce vibrations, then weighing accuracy is improved, but the device complexity increases
Solution Approach 1:
The connecting means is divided into three sections: first section permanently connected to container, second section permanently connected to conveyor, and third section hingedly connected to both. This segmentation allows different parts to perform different functions - the first and second sections provide stable connections while the third hinged section acts as a vibration isolator, resolving the contradiction between efficient power transfer and vibration reduction for accurate weighing
Solution Approach 2:
The hinged third section performs multiple functions simultaneously: it transfers vertical loads from the container to the conveyor, allows rotational movement to reduce vibrations, and maintains structural connection. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity while achieving vibration reduction
