Radiator Fan Shroud Integration for Lightweight Motor Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional radiator fan devices are heavy due to the use of a plate to secure the motor to the shroud.
Innovation Solution
A radiator fan device design that integrates a shroud body and motor anchor part, utilizing a stator core with a cylindrical bearing support hole and engaging parts to secure the motor, eliminating the need for additional securing plates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a plate is used to secure the motor to the shroud, then the motor is firmly fixed, but the overall device weight increases
Solution Approach 1:
The motor anchoring part is integrated into the shroud as a single piece structure, eliminating the need for separate plates to secure the motor. The shroud and motor anchoring part form an integrated component that firmly fixes the motor while reducing the number of parts and overall weight.
2Reliability
If multiple separate components are used to secure the motor, then the assembly is robust, but the device complexity increases
Solution Approach 1:
The shroud and motor anchoring part are merged into a single integrated component, reducing the total number of parts while maintaining the robustness of motor fixation through the integrated structure's inherent design.
3Strength
If additional securing plates are used, then the motor attachment is stronger, but manufacturing cost increases
Solution Approach 1:
By integrating the motor anchoring part into the shroud as a single piece, the manufacturing process is simplified, reducing the number of separate components that need to be produced and assembled, thereby lowering manufacturing costs while maintaining attachment strength.
Solution Approach 2:
The unnecessary securing plates are extracted/removed from the design, keeping only the essential integrated structure that provides sufficient strength for motor attachment without the added cost of additional components.

AI summary
A radiator fan device may include a fan, a motor connected to the fan, and a shroud overlying the fan and the motor. The fan may include a hub and a plurality of blades projecting from the hub. The motor may be configured to rotationally drive the fan. The shroud may integrally include a shroud body overlying the fan and the motor and/or a motor anchor part securing the motor to the shroud.
