Flat-Profiled Mixing Rotor for Building Materials
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mixing rotors for producing free-flowing building materials, such as mortar or concrete, require complex production steps and are costly due to forging and forming processes, as well as the connection of multiple components.
Innovation Solution
A mixing rotor design where the drive shaft and mixing arms are manufactured from flat-profiled material sections, allowing for simplified production through cutting processes without the need for significant shaping, and can be connected using welding or other material bonds, reducing the number of manufacturing steps and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional forging and forming processes are used to manufacture mixing rotors, then mechanical strength and durability are improved, but manufacturing complexity and production costs increase
Solution Approach 1:
The patent changes the manufacturing approach from traditional forging and forming processes to cutting and shaping processes. Instead of forming complex 3D shapes through multiple forging steps, the invention cuts the mixing rotor components from flat-profiled semi-finished products, significantly reducing manufacturing complexity while maintaining mechanical strength through proper material selection and heat treatment of the flat profiles.
2Adaptability or versatility
If multiple components are connected to form the mixing rotor, then functional requirements are met, but production costs and assembly complexity increase
Solution Approach 1:
The patent combines multiple functional components (drive shaft, mixing arms, connecting elements) into a single integrated flat-profiled structure that is cut from one piece of material. This merging eliminates the need for separate manufacturing and assembly of multiple components, reducing production costs and assembly complexity while maintaining all necessary functions through the integrated design.
3Adaptability or versatility
If complex forming processes are used to create mixer geometries, then design flexibility is improved, but production time and costs increase
Solution Approach 1:
The patent segments the mixing rotor design into modular flat-profiled components with standardized connection interfaces. This segmentation allows different mixing arm configurations and geometries to be created by simply changing the cut patterns and arrangements of the flat profiles, providing design flexibility without requiring complex forming processes for each variation, thus reducing production time.
