Upper Front Crossmember With Multi-Region Impact Sensor Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle designs require different front crossmember configurations for impact sensors to comply with varying regional regulations, leading to increased storage and logistics costs due to the need for different part references.
Innovation Solution
A single upper front crossmember with three attachment interfaces, positioned centrally and symmetrically, allows for the installation of impact sensors according to both European and North American standards, reducing the need for multiple part references.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different front crossmember configurations are used to meet regional sensor installation requirements, then regulatory compliance is achieved, but storage and logistics costs increase due to multiple part references
Solution Approach 1:
The crossmember is designed with three attachment interfaces that can accommodate different sensor configurations (single central sensor for European markets or two lateral sensors for North American markets) using the same part reference, making the component universal across different regional requirements
2Adaptability or versatility
If attachment interfaces are positioned on side jambs, then North American market requirements are met, but European market requirements cannot be satisfied
Solution Approach 1:
The crossmember is divided into three distinct attachment interface locations: one central interface on the crossmember body for European markets, and two lateral interfaces near the side jambs for North American markets, allowing selective use based on regional requirements

AI summary
The invention relates to a front end (1) upper crossmember (2) for a motor vehicle, intended to extend horizontally at the front of the vehicle and having at least one attachment interface (23, 24, 25) for shock sensor (26), the at least one attachment interface comprising: - a nut (27) placed in an orifice (28) formed in a wall (29, 30, 31) of the crossmember in such a way as to allow a shock sensor to be fixed by bolting, - an oblong pre-positioning and indexing hole (33) arranged on the wall in proximity to the nut and provided to receive a protuberance of complementary shape (34) arranged on this same shock sensor; characterized in that the crossmember has a first attachment interface (23) formed in its central part and second and third attachment interfaces (24, 25) formed respectively at each of its two lateral ends.
