Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric vehicle chassis have fixed interior spaces and inaccessible battery modules, failing to adapt to varying user needs and requiring difficult replacement procedures.
Innovation Solution
A vehicle chassis with a frame that can expand and collapse, featuring removably connected loading devices and battery modules, allowing for adjustable interior space and easier access to battery modules for maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the vehicle chassis uses a fixed interior space design like traditional vehicles, then the structural simplicity is maintained, but the adaptability to varying user needs deteriorates
Solution Approach 1:
The loading device is divided into multiple independently removable loading boxes, each capable of being separated and reconfigured. This segmentation allows the interior space to be adapted to different user needs by rearranging individual boxes, while maintaining a relatively simple overall chassis structure.
Solution Approach 2:
The loading device transitions from a fixed configuration to a dynamic, reconfigurable system. The loading boxes can be removed and repositioned based on different usage scenarios, enabling the chassis to adapt to varying user needs without requiring a completely complex redesign of the entire structure.
2Ease of operation
If the battery modules are mounted underneath passenger seats or inside the luggage space, then the space utilization is improved, but the ease of access for replacement deteriorates
Solution Approach 1:
The battery storage system is segmented into individual removable loading boxes that can be easily accessed and replaced. Each loading box containing battery modules can be independently removed from the chassis, significantly improving ease of access for maintenance while the boxes can be arranged to optimize interior space utilization.
Solution Approach 2:
The battery modules are extracted from fixed positions underneath seats or inside luggage spaces and placed into removable loading boxes. This extraction allows for easy removal and replacement of battery modules while the loading boxes can be positioned to efficiently utilize the available interior space.
3Adaptability or versatility
If the loading device is fixed to the vehicle frame, then the structural stability is improved, but the adaptability of interior space deteriorates
Solution Approach 1:
The loading device employs a dynamic connection system where loading boxes can be easily attached and detached from the vehicle frame. This dynamic design allows the loading boxes to be securely fixed during normal operation for stability, while enabling quick reconfiguration or removal for different interior space requirements.
Solution Approach 2:
The loading device is segmented into individually removable loading boxes that can be selectively attached or detached. This segmentation provides structural stability when boxes are mounted, while allowing flexible reconfiguration of interior space by removing or repositioning individual boxes as needed.

AI summary
A vehicle chassis including a vehicle frame defining an inner space and being operable to switch between a first expanded state and a collapsed state, and a loading device mounted to the inner space and removably connected to the vehicle frame. The loading device defines a first loading surface when the vehicle frame is in the first expanded state, and the loading device defines a second loading surface that is smaller than the first loading surface when the vehicle frame is in the collapsed state.
