Solution Overview
Problem
Existing systems for transporting and handling goods separate the functions of transportation and weighing, requiring additional equipment and logistical efforts, which is inefficient and costly.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate weighing devices are used to determine the mass of goods, then the mass can be accurately measured, but additional equipment and logistical expenditure are required
Solution Approach 1:
The patent combines the weighing function with the transport device by integrating sensors into the mover that detect changes in the mover's state of motion (acceleration, velocity, position) caused by the mass of goods on the carrier. This merging eliminates the need for separate weighing devices while maintaining mass determination capability.
Solution Approach 2:
The mover in the transport device is given multiple functions: it serves both as the actuator for contact-free transport and as the sensing element for mass determination. The sensors integrated into the mover detect state of motion variables that reveal the mass of goods, making the transport device universal for both transportation and weighing tasks.
2Measurement precision
If separate weighing devices are used to determine the mass of goods, then accurate mass measurement is achieved, but logistical efforts and time are increased
Solution Approach 1:
By merging the weighing function into the transport device itself, the patent enables simultaneous transportation and weighing operations. The sensors continuously monitor the mover's state of motion during transport, allowing mass determination to occur during the transport process rather than requiring separate weighing steps.
Solution Approach 2:
The patent enables continuous mass determination during the entire transport process. The sensors continuously detect state of motion variables (acceleration, velocity, position) of the mover, providing ongoing mass information without interrupting the transport flow, thus eliminating idle time associated with separate weighing operations.
3Ease of operation
If the mover is moved relative to the stator using magnetic interaction, then contact-free and controllable movement is achieved, but the system complexity increases
Solution Approach 1:
The patent replaces mechanical contact-based drive systems with an electromagnetic field-based system. The stator generates a magnetic field that interacts with the mover to produce contact-free movement and positioning. This substitution eliminates mechanical wear and simplifies control while enabling precise, contactless operation.
Solution Approach 2:
The patent utilizes changes in the magnetic field parameters (strength, distribution, timing) controlled by the control unit to achieve precise control of the mover's position and motion state. By dynamically adjusting magnetic field parameters rather than mechanical parameters, the system achieves ease of operation with programmable control.
