Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric motors in air blower devices often suffer from poor coaxiality between the rotor and stator, leading to jerky rotation and potential engine malfunctions due to the lack of a unified support and cooling system.
Innovation Solution
A bi-functional part that integrates both the radiator and support element for the rotor and stator, allowing for a single, unified component that provides both structural support and cooling, ensuring precise coaxial alignment and efficient heat dissipation through a flow of air or fluid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If separate radiator and support element are used, then manufacturing flexibility is improved, but coaxiality between rotor and stator deteriorates
Solution Approach 1:
The patent combines the radiator and support element into a single integrated component. The support element has a hollow cylindrical shape that serves dual purposes: providing structural support for the rotor and stator while simultaneously functioning as a radiator with internal channels for coolant flow. This merging eliminates the need for separate positioning operations between two components, ensuring precise coaxiality is inherently achieved through the monolithic structure.
2Ease of repair
If multiple separate components are used, then ease of repair is improved, but device complexity increases
Solution Approach 1:
The support element integrates multiple functions into a single component: structural support, radial positioning, and thermal dissipation. By combining the radiator and support element, the patent reduces the total number of parts while maintaining the ability to service the motor, as the integrated component eliminates alignment issues that would complicate assembly and disassembly during maintenance.
3Ease of manufacture
If separate radiator and support element are used, then manufacturing cost is reduced, but operational reliability deteriorates
Solution Approach 1:
The integrated support element and radiator ensure reliable operation by eliminating potential misalignment between separate components. The monolithic structure guarantees precise coaxial positioning of the rotor and stator, preventing operational issues such as vibration and uneven wear. The integration also ensures consistent thermal management, as the coolant channels are precisely formed within the support structure itself.
4Manufacturing precision
If unified bi-functional part is used, then manufacturing precision is improved, but manufacturing complexity increases
Solution Approach 1:
The support element is designed as a multi-functional component that simultaneously provides structural support, radial positioning, and thermal dissipation. The hollow cylindrical shape with internal channels allows it to serve as both a mechanical support structure and a radiator, achieving multiple functions in a single geometric form that is manufactured as one piece.
Solution Approach 2:
The patent merges the radiator and support element into a single integrated component. The support element has a hollow cylindrical shape that serves dual purposes: providing structural support for the rotor and stator while simultaneously functioning as a radiator with internal channels for coolant flow. This merging eliminates the need for separate positioning operations between two components, ensuring precise coaxiality is inherently achieved through the monolithic structure.

This solution enhances the reliability and homogeneity of the motor's operation by ensuring precise coaxiality and effective cooling, reducing manufacturing complexity and improving the motor's performance by eliminating the need for separate radiator and support elements.
Implementation Method 1
a flow of air (10) allowing the cooling of said motor (101)... the flow of fluid passing through the motor support cools the radiator and that said radiator cools said electronic organ
Implementation Method 2
the bi-functional part is made of metal. Thus, the base acting as a radiator can effectively cool the electronic component by thermal conduction
