Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single cleaning blade shaft is arranged in a hot washing machine with smooth inner wall, then the device structure is simple, but the mechanical friction is small and cleaning effect is insufficient
Solution Approach 1:
The single cleaning blade shaft is segmented into multiple cleaning blade shafts arranged within the hot washing machine. Each shaft carries multiple cleaning blades that work simultaneously, increasing the total cleaning surface area and mechanical friction with the materials without significantly complicating the overall device structure.
Solution Approach 2:
The cleaning system transitions from a single-axis rotation to a multi-axis three-dimensional cleaning configuration. Multiple cleaning blade shafts are arranged at different positions and angles within the cylindrical cavity, creating comprehensive three-dimensional mechanical friction that eliminates dead angles and improves cleaning coverage.
2Device complexity
If a feeding screw conveyor with dead angle is used to transport materials, then the device structure is simple, but materials accumulate in dead angles and affect next batch processing
Solution Approach 1:
The static dead angle structure of the feeding screw conveyor is transformed into a dynamic multi-axis variable-speed cleaning system. The multiple cleaning blade shafts rotate at different speeds and directions, continuously changing the cleaning angles and eliminating material accumulation zones that would otherwise form in fixed dead angles.
Solution Approach 2:
The multi-axis variable-speed rotation ensures continuous and comprehensive cleaning action throughout the entire hot washing cycle. All regions of the cylindrical cavity, including previously dead angle areas, are continuously engaged in the cleaning process, preventing material accumulation and ensuring uninterrupted processing between batches.
3Ease of manufacture
If separate hot washing machine, screw conveyor, and friction machine are used, then each device can be optimized independently, but the quantity of devices is large and space occupation is large
Solution Approach 1:
The hot washing machine, feeding screw conveyor, and friction machine are merged into a single integrated multi-axis variable-speed hot washing machine. The multiple cleaning blade shafts perform both the hot washing and friction cleaning functions that previously required separate devices, significantly reducing space occupation while maintaining the ability to optimize cleaning performance.
Solution Approach 2:
The integrated hot washing machine performs multiple functions simultaneously: hot washing, feeding, and friction cleaning. The multi-axis variable-speed system can adapt its rotation speeds and patterns to perform different cleaning tasks within a single device, replacing multiple specialized devices with one universal machine.

AI summary
A multi-axis variable-speed hot washing module and a hot washing method thereof are provided. The multi-axis variable-speed hot washing module includes a storage assembly, a dehydration assembly, and one or more multi-axis variable-speed hot washing machines, where the multi-axis variable-speed hot washing machine is connected to the storage assembly and the dehydration assembly. Batches of materials are stored in the storage assembly. When cleaning, the materials are put from the storage assembly into one or more multi-axis variable-speed hot washing machines, and medicinal water is added. The multi-axis variable-speed hot washing machine replaces functions of a hot washing machine, a screw, and a friction machine, and has relatively large mechanical friction on the materials during cleaning. The materials after being hot washed by the multi-axis variable-speed hot washing machine are transported to the dehydration assembly for dehydration, so as to implement separation of cleaning water and the materials.
