Vehicle Bumper Beam Extension Member Impact Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vehicle body structure requires a specification and significant time and effort for attaching the outer elongated member to the vehicle body frame, which is inefficient.
Innovation Solution
A vehicle body structure that includes a bumper beam, an extension member between the bumper beam and the vehicle body frame, and an elongated member that absorbs impact, where one end of the elongated member is connected to the bumper beam and the other end is connected to the extension member, eliminating the need for direct attachment to the vehicle body frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the outer elongated member is directly attached to the vehicle body frame, then the impact absorption function is achieved, but the attachment process requires time and effort
Solution Approach 1:
The patent introduces an extension member as an intermediary component between the bumper beam and the vehicle body frame. This extension member eliminates the need for direct attachment of the elongated member to the frame, thereby reducing attachment time and effort while maintaining the impact absorption function through the elongated member's buckling mechanism
2Stability of the object's composition
If the outer elongated member is directly attached to the vehicle body frame, then the structural connection is established, but the attachment specification becomes complex
Solution Approach 1:
The extension member serves as a mediator that simplifies the attachment specification. By providing a standardized interface between the bumper beam and the vehicle body frame, it eliminates the need for complex direct attachment specifications while ensuring stable structural connection and proper load transmission
