Modular Motor Housing Structure for Multi-Type Vehicle Motors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for manufacturing motor accommodation structural bodies in automobiles require significant changes in equipment and processes when different types of motors are installed, leading to increased costs and inefficiencies due to the need for new dies and evaluation processes.
Innovation Solution
A modular motor accommodation structural body design that separates common components from type-specific parts, allowing for the reuse of existing manufacturing equipment and minimizing structural changes, featuring a housing with a guide unit and covers that can accommodate various motor sizes and types without requiring extensive retooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a different type of die is manufactured to accommodate a different type of motor, then the structural body can be adapted to the new motor type, but the manufacturing cost and time increase due to die manufacturing and evaluation
Solution Approach 1:
The structural body is divided into a housing and a separate cover component. The cover is designed as a detachable module that can be removed and replaced to accommodate different motor types, while the main housing remains unchanged. This segmentation allows adaptation to different motors without manufacturing new dies for the entire structural body.
Solution Approach 2:
The housing is designed with a universal structure that can accommodate multiple motor types through the interchangeable cover. The cover serves multiple functions: it closes the housing, provides mounting interfaces for different motor types, and seals the internal components. This multi-functionality reduces the need for specialized dies for each motor type.
2Adaptability or versatility
If manufacturing equipment is changed to manufacture a structural body for a different type of motor, then the structural body can accommodate the new motor, but the equipment change requires additional costs and time
Solution Approach 1:
The structural body is segmented into a fixed housing and a replaceable cover module. The cover contains all motor-type-specific features, allowing it to be designed as a separate, interchangeable component. This enables production line flexibility where different covers can be installed on the same housing without changing manufacturing equipment.
Solution Approach 2:
The cover is designed as a dynamic, replaceable component rather than a fixed part of the housing. This allows the cover to be swapped out to match different motor types, providing adaptability without requiring permanent equipment modifications. The detachable nature of the cover enables quick changes in production configuration.
3Adaptability or versatility
If a new die is manufactured to change the structure of the structural body for a different motor type, then the structural body can be reconfigured, but additional costs and time are required for die evaluation
Solution Approach 1:
The structural body is divided into a housing and a separate cover, with the cover serving as the adaptable component. This segmentation isolates the structural changes to the cover only, which can be designed and tested independently before production, reducing the need for extensive re-evaluation of the entire structural body.
Solution Approach 2:
The cover can be designed as a modified copy or variant of existing cover designs, reusing proven structural elements and mounting interfaces. This approach allows adaptation to new motor types while maintaining reliability through proven design patterns, reducing the need for comprehensive new die evaluation.
