Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle bodies face challenges in accommodating in-wheel system components, requiring significant space and increased manufacturing complexity, while also needing to absorb collision impacts and ensure passenger safety.
Innovation Solution
A vehicle body design featuring a grid-shaped floor member and frame member with spaced support members, allowing a high-voltage battery to be mounted between them, and a seat coupled to the frame member, which provides structural rigidity and simplifies assembly, while also enabling efficient use of space and protection from impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If wheel housings and drive devices occupy considerable space in conventional vehicles, then sufficient space for components is provided, but the vehicle body becomes increasingly complicated and assembly time increases
Solution Approach 1:
The vehicle body is divided into modular components: floor member, frame member, and support members that can be manufactured separately and assembled together. This segmentation allows each component to be optimized independently while simplifying the overall manufacturing and assembly process.
Solution Approach 2:
The support members serve multiple functions: they provide structural support, define the battery mounting space, and contribute to the overall rigidity of the vehicle body. This multi-functionality reduces the need for separate components, thereby simplifying the device complexity.
2Reliability
If the vehicle body is designed to absorb collision impacts and protect passengers, then passenger safety is improved, but the structural complexity and manufacturing difficulty increase
Solution Approach 1:
The vehicle body is divided into modular components: floor member, frame member, and support members that can be manufactured separately and assembled together. This segmentation allows each component to be optimized independently for both safety and manufacturing ease.
Solution Approach 2:
The support members act as intermediary elements that connect the floor member and frame member, providing structural support and impact absorption capability while simplifying the overall manufacturing process through standardized coupling mechanisms.
3Ease of operation
If the vehicle adopts an in-wheel system, then the drive process is simplified, but the vehicle body must be redesigned to provide space for wheel housings while ensuring sufficient rigidity
Solution Approach 1:
The vehicle body is segmented into floor member, frame member, and support members that can be independently designed and assembled. This modular approach allows the body structure to be optimized for in-wheel systems without increasing overall complexity.
Solution Approach 2:
The support members provide multiple functions including structural support, battery mounting, and rigidity enhancement, thereby reducing the need for additional components and simplifying the overall vehicle body structure despite the in-wheel system requirements.
4Adaptability or versatility
If more components are added to the vehicle, then functionality is improved, but the manufacturing and assembly process becomes increasingly complicated and time-consuming
Solution Approach 1:
The vehicle body is divided into modular components that can be manufactured independently and assembled quickly. This segmentation reduces assembly time while maintaining the ability to incorporate multiple functional components.
Solution Approach 2:
Multiple functions are merged into the support members, which simultaneously provide structural support, define battery space, and contribute to overall rigidity. This consolidation reduces the number of separate components and assembly steps, thereby reducing assembly time.

AI summary
A vehicle body includes a floor member, a support member coupled to an upper surface of the floor member, and a frame member coupled to an upper end of the support member to define a space between the floor member and the frame member, wherein the space is configured to house an item. The item may include a high-voltage battery.
