HVAC Motor Support Interface for Vehicle Volute Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current motor support assemblies for heating, ventilation, and air conditioning installations in vehicles are not adaptable to different vehicle designs and require specific design for each application, leading to increased manufacturing costs and time for adaptation.
Innovation Solution
A motor support assembly with a connection part that forms an interface between the motor support and the volute, allowing for adaptation by varying the connection part's design while keeping other elements standardized, including a guide portion for cooling air flow to cool the motor and control module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the motor support assembly is designed specifically for each application, then the adaptation to different vehicle designs is achieved, but the manufacturing cost and design time increase
Solution Approach 1:
The motor support assembly is divided into modular components: a standardized motor support unit and a configurable connection part. The connection part is further segmented into a mounting flange for the volute and an interface flange for the motor support, allowing independent design of each segment. This segmentation enables the core motor support assembly to remain standardized while only the connection part needs adaptation for different vehicle designs, reducing overall design complexity and manufacturing costs.
2Adaptability or versatility
If the motor support assembly is designed specifically for each application, then the adaptation to different vehicle designs is achieved, but the manufacturing cost increases
Solution Approach 1:
The motor support assembly is designed with universal standardized components that can be used across different vehicle applications. The motor support unit, fan wheel housing, and sealing elements are standardized and interchangeable. Only the connection part (mounting flange and interface flange) varies between applications, allowing the majority of the assembly to be manufactured using the same processes and tools, thereby reducing manufacturing costs while maintaining adaptability.
3Adaptability or versatility
If the motor support assembly is designed specifically for each application, then the adaptation to different vehicle designs is achieved, but the design time increases
Solution Approach 1:
The motor support assembly is pre-designed with standardized components and a modular structure that anticipates future adaptation needs. The connection part is designed as a separate, easily configurable module that can be adapted to different vehicle designs without redesigning the entire assembly. This preliminary structuring with standardized interfaces and modular components significantly reduces design time for new applications, as engineers only need to configure the connection part rather than redesign the complete motor support assembly.
