Adaptable Motor Housing for Variable Axial Length Electric Motors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control devices for internal combustion engines and vehicles require different device housings for varying electric motor powers, leading to increased production costs due to varying geometries.
Innovation Solution
Adapting the motor accommodating space within the device housing by varying only the axial length while maintaining a constant motor cross section, using interchangeable covers or spacer elements to accommodate electric motors of different lengths, allowing for cost-effective production and efficient protection of the motor.

Engineering Contradiction Analysis
1Adaptability or versatility
If different device housings are used for varying electric motor powers, then the control device can be adapted to different power requirements, but the production costs increase due to varying geometries
Solution Approach 1:
The device housing is designed as a universal component that can accommodate multiple electric motor types and power ratings. The housing includes a standardized motor accommodating space with a common cross section that can fit motors of different lengths, eliminating the need for different housing geometries for different power requirements.
Solution Approach 2:
The invention changes only the axial length parameter of the motor accommodating space while keeping the cross-sectional dimensions constant. This allows adaptation to different motor sizes by varying only one dimension (length) rather than redesigning the entire housing geometry, thereby reducing production costs while maintaining adaptability.
2Power
If different electric motors with different geometries are used, then different motor powers can be achieved, but the device housing must be varied accordingly, increasing complexity
Solution Approach 1:
The motor accommodating space is segmented into a standardized cross-sectional portion (common to all motors) and a variable axial length portion. This segmentation allows the housing structure to remain simple and standardized while accommodating motors of different powers through only the length dimension.
Solution Approach 2:
A single universal device housing design serves multiple functions by accommodating various electric motor types and power ratings. The standardized cross section and modular length adaptation enable one housing design to replace multiple specialized housing designs.
