Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vehicle body structures for electric vehicles face challenges in manufacturing complexity and reduced collision energy efficiency due to multiple components with connection relationships, which complicates the transmission of collision energy from the front longitudinal beam to the sill longitudinal beam.
Innovation Solution
A vehicle body front engine compartment framework with an integrally-formed front longitudinal beam rear section member, comprising a base part and two side parts connected to a cross beam, uses a connecting unit with multiple sled boards to support force transmission, and incorporates rib assemblies for enhanced structural strength and collision safety, utilizing C611 aluminum alloy without heat treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple separate components are used to form the front longitudinal beam rear section, then manufacturing flexibility and ease of repair are improved, but manufacturing complexity and device complexity increase
Solution Approach 1:
The patent merges the front longitudinal beam rear section into an integrally-formed structure with the cross beam, eliminating the need for separate components and connections. This integration reduces manufacturing complexity and assembly steps while maintaining the structural functionality of energy transmission paths.
2Adaptability or versatility
If multiple components with connection relationships are used, then adaptability and ease of operation are improved, but collision energy transmission efficiency deteriorates
Solution Approach 1:
The integrally-formed structure eliminates connection interfaces between components, creating continuous collision energy transmission paths. This merging ensures that collision energy from the front longitudinal beam can be efficiently transmitted through the rear section to the sill longitudinal beam without energy loss at connection points.
3Manufacturing precision
If integrally-formed structure is used for the front longitudinal beam rear section, then manufacturing precision and product consistency are improved, but device complexity increases
Solution Approach 1:
The patent combines the front longitudinal beam rear section with the cross beam into a single integrally-formed component, eliminating the need for precise matching and connection between separate parts. This integration improves product consistency by reducing assembly variability while the structural complexity is managed through optimized design of the integrated form.
