Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle body frames face issues with bolt connections, where insufficient tightening torque leads to loosening during use, and the assembly process is cumbersome, affecting structural strength and efficiency.
Innovation Solution
A body frame design featuring transverse and longitudinal beams with sliding grooves and rivets, where transverse and longitudinal rivets are slidably mated with these grooves, providing a secure and efficient assembly method.

Engineering Contradiction Analysis
1Ease of operation
If bolt connection is used to connect joints with body frame, then the assembly can be disassembled and reassembled, but the tightening torque may be insufficient causing loosening during use
Solution Approach 1:
The joint is divided into multiple connection components including connection plates, connection pins, and locking components. Each component performs a specific function: connection plates provide mounting surfaces, connection pins establish the mechanical connection, and locking components prevent loosening. This segmentation allows the connection to achieve both reliability through multiple locking mechanisms and ease of operation through modular assembly and disassembly.
2Ease of operation
If bolt connection is used to connect joints with body frame, then the assembly can be disassembled and reassembled, but the assembly process becomes cumbersome affecting assembly efficiency
Solution Approach 1:
The connection plates are pre-equipped with connection pin holes and locking component mounting positions during manufacturing. The connection pins are pre-formed with specific geometries that align with predetermined holes in the beams. This preliminary preparation eliminates the need for complex alignment and drilling operations during assembly, significantly improving assembly efficiency while maintaining the ability to disassemble and reassemble the connection.
3Reliability
If rivet connection is used instead of bolt, then loosening is avoided and structural strength is improved, but the assembly process becomes more complex
Solution Approach 1:
The connection pin is designed with a specific geometry that allows it to be inserted through aligned holes in the beam and joint, then locked in place. The locking component transforms the connection from a simple pin to a secured fastening system. This dynamic approach enables the connection to achieve rivet-like reliability (preventing loosening) while maintaining easier assembly through a standardized insertion and locking process rather than complex riveting operations.

AI summary
A body frame and a vehicle having the same are provided. The body frame includes: a transverse beam, provided with a transverse sliding groove; a longitudinal beam, connected with the transverse beam and provided with a longitudinal sliding groove; and a joint, disposed at a junction of the transverse beam and the longitudinal beam and mounted to the transverse beam by a transverse rivet and to the longitudinal beam by a longitudinal rivet. The transverse rivet is slidably mated with the transverse sliding groove, and the longitudinal rivet is slidably mated with the longitudinal sliding groove.
