Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If permanent magnets are used in magnet-operated conveying devices, then conveying function is achieved, but contamination of permanent magnets causes local changes in magnetic field leading to mechanical disruptions and conveying speed variations
Solution Approach 1:
The cleaning device performs preliminary cleaning action on the permanent magnets before they complete their conveying cycle. A cleaning element moves along the permanent magnet to remove particles proactively, preventing contamination from causing magnetic field disruptions and conveying interruptions.
Solution Approach 2:
A cleaning element acts as an intermediary between the permanent magnet and the particles. This cleaning element selectively interacts with particles on the magnet surface through magnetic or adhesive forces, removing contaminants without directly contacting or damaging the permanent magnet itself.
2Object-affected harmful factors
If cleaning is performed on permanent magnets, then particle removal is achieved, but mechanical cleaning methods may disrupt the conveying process and cause production downtime
Solution Approach 1:
The cleaning operation is integrated into the continuous conveying cycle without interruption. The cleaning element operates simultaneously with the conveying elements in motion, maintaining continuous particle removal while the conveyor runs, thus eliminating production downtime associated with separate cleaning operations.
Solution Approach 2:
The cleaning device is self-contained within the conveying system, using the motion of the conveying elements themselves to facilitate the cleaning process. The system cleans itself during normal operation without requiring external intervention or stopping the production line.
3Reliability
If a cleaning device is integrated into the conveying system, then continuous cleaning is achieved, but device complexity increases
Solution Approach 1:
The cleaning device is merged with the existing conveying system structure. The cleaning element is integrated alongside the conveying elements, sharing common support structures and motion mechanisms, thereby minimizing additional complexity while achieving continuous cleaning functionality.
Solution Approach 2:
The cleaning element can be designed with multi-functionality, potentially serving both cleaning purposes and structural support roles. The same component may facilitate particle removal while also contributing to the mechanical framework of the conveying system, reducing the need for separate dedicated cleaning structures.

Function Achieved in This Case
The cleaning device maintains a stable conveying speed and prevents mechanical disruptions, ensuring a trouble-free and failure-free conveying process by continuously removing contaminants, thus saving costs and avoiding production downtime.
Implementation Method 1
the cleaning device is a magnetic cleaning device and the particles are removed from the surface of the permanent magnet using magnetic force
Implementation Method 2
or a cleaning device having an adhesive force, which removes the particles from the surface of the permanent magnet by a high adhesion effect or sticking of the particles to the cleaning device
