Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing support devices for electric driving machines in all-electric or hybrid vehicles require new frame designs for each new vehicle structure or electric drive machine shape, leading to increased costs and resource mobilization due to the need for custom adaptations.
Innovation Solution
A support device with an adjustable frame and interface parts coupled to elastic wedges and fixing screws, allowing for adaptable positioning to accommodate different vehicle structures and electric drive machine shapes, eliminating the need for new framework designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a new frame is designed for each new vehicle structure or electric drive machine shape, then the support device fits the specific structure and shape requirements, but the design cost and resource mobilization increase
Solution Approach 1:
The frame is divided into multiple adjustable segments with interface parts that can be independently positioned. Each interface part can be adjusted to different locations on the frame structure, allowing the same frame design to accommodate various vehicle structures and electric drive machine shapes without requiring complete redesign.
Solution Approach 2:
The frame incorporates adjustable interface parts and fixing screeds that can be dynamically repositioned along the frame structure. This dynamic adjustability allows the support device to adapt to different configurations while maintaining a single standardized frame design, eliminating the need for multiple custom frame designs.
2Adaptability or versatility
If a new frame is designed for each new vehicle structure or electric drive machine shape, then the support device fits the specific structure and shape requirements, but the production cost and human resource investment increase
Solution Approach 1:
The frame is designed as a universal support structure with standardized interface parts and fixing screeds that can serve multiple functions across different vehicle models and electric drive machine configurations. This single standardized frame design replaces the need for multiple custom-designed frames, reducing manufacturing costs and human resource investment while maintaining adaptability to various applications.
3Ease of manufacture
If fixed position interface parts are used on the frame, then the frame structure is simple and easy to manufacture, but the support device cannot adapt to different vehicle structures and electric drive machine shapes
Solution Approach 1:
The interface parts are designed with adjustable positioning capabilities along the frame structure, allowing them to be repositioned to different locations as needed. This dynamic adjustability enables the same simple frame design to accommodate various vehicle structures and electric drive machine shapes without compromising manufacturing simplicity.
Solution Approach 2:
Adjustable fixing screeds serve as intermediary elements between the fixed frame structure and the interface parts. These screeds can be repositioned along the frame to accommodate different positioning requirements, providing adaptability while maintaining the simplicity of the underlying frame structure.
