Vehicle Bracket With Brittle Opening For Vibration And Crash Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing onboard equipment fixing structures in vehicles fail to effectively address both vertical load vibrations and collision safety while minimizing the number of parts and installation space.
Innovation Solution
A bracket system with a vehicle body attaching portion, an equipment attaching portion, and connecting vertical wall parts that form a torsionally rigid structure to resist vibrations and include a brittle opening portion for deformation during collisions, reducing the risk of damage to onboard equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a separate bracket is used to increase mounting strength against vertical load, then the vertical mounting strength is improved, but the number of parts and installation space increase
Solution Approach 1:
The patent combines the collision safety function and vertical load resistance function into a single bracket structure. The bracket includes a vehicle body attaching portion, equipment attaching portion, and connecting portion with an opening, forming an integrated L-shaped structure that simultaneously provides both safety performance and vibration resistance without requiring separate brackets for each function.
2Reliability
If the vehicle body attaching portion is disposed closer to the outside of the vehicle body than the equipment attaching portion, then the safety performance during collision is improved, but the mounting strength against vertical load may be reduced
Solution Approach 1:
The patent applies different functional qualities to different portions of the bracket. The connecting portion includes a brittle part that is specifically designed to deform during collision to absorb impact energy, while the vehicle body attaching portion and equipment attaching portion maintain sufficient strength for vertical load resistance. This local differentiation allows the bracket to optimize for both collision safety and mounting strength simultaneously.
Solution Approach 2:
The bracket is segmented into distinct functional portions: a vehicle body attaching portion for mounting, an equipment attaching portion for securing the device, and a connecting portion with a brittle part that deformable during collision. This segmentation allows each portion to be optimized for its specific function while working together as an integrated structure.

Function Achieved in This Case
Enhances mounting strength against vertical vibrations and collision safety without increasing the number of parts or installation space, mitigating loads on onboard equipment during collisions.
Implementation Method 1
the connecting portion includes a brittle part which becomes a starting point of a deformation in a direction which intersects an input direction of a collision load

AI summary
An onboard equipment fixing structure for an onboard equipment (12) - in particular an electronic equipment- which is mounted in a vehicle, it includes a bracket (31) which fixes the onboard equipment (12) to a vehicle body part of the vehicle (3). The bracket includes a vehicle body attaching portion (310) which is attached to the vehicle body part (3,3a) , an equipment attaching portion which is attached to a side surface (12b) of the onboard equipment which extends in a vertical direction of a vehicle body, a connecting portion (314L,314R) which connects the vehicle body attaching portion and the equipment attaching portion, and an opening portion (313) which is formed in an area surrounded by the vehicle body attaching portion (310), the equipment attaching portion and the connecting portion (310). The vehicle body attaching portion is fixed to the vehicle body part so as to be disposed closer to the outside of the vehicle body than the equipment attaching portion. It reduces vibrations due to vertical loads while keeping the advantages of the bracket in case of a crash.
