Composite Side Airbag Bracket to Prevent Bolt-Fastening Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional side airbag brackets in automotive vehicles are prone to damage or deformation when fastened with bolts, leading to instability and potential failure in deploying the side airbag, and they often require additional components and complex assembly processes, which increase manufacturing time and reduce efficiency.
Innovation Solution
A bracket system comprising a synthetic resin mounting plate and a metal bracket clip with a coupling part, support plates, and a restraint member, designed to securely fasten the side airbag without additional parts and prevent deformation during bolt tightening, featuring a coupling hole, through-holes, and a hooking mechanism for stable fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional plastic bracket is used to secure the side airbag, then the assembly process is simple, but the bracket is broken or deformed when fastened by a bolt
Solution Approach 1:
The bracket is constructed by combining a mounting plate made of synthetic resin material with a bracket clip made of metal material. This composite structure allows the metal bracket clip to provide the necessary strength and rigidity to prevent deformation during bolt fastening, while the synthetic resin mounting plate provides ease of manufacture and assembly. The two materials complement each other to resolve the contradiction between assembly simplicity and bracket integrity.
2Strength
If additional securing devices and components are added to secure the side airbag, then the bracket strength is improved, but the assembly process becomes complex and manufacturing time increases
Solution Approach 1:
The mounting plate and bracket clip are merged into a single integrated bracket assembly that functions as a complete securing device. The bracket clip is coupled to the mounting plate to form a unified structure that provides both mounting and securing functions. This merging eliminates the need for additional separate securing devices and components, thereby maintaining bracket strength while simplifying the overall device complexity and reducing manufacturing time.
3Ease of manufacture
If a single-material bracket is used, then the manufacturing process is simple, but the bracket cannot simultaneously provide flexibility and strength
Solution Approach 1:
The bracket uses a composite material construction where the mounting plate is made of synthetic resin material providing flexibility and ease of manufacture, while the bracket clip is made of metal material providing strength and rigidity. This composite approach allows the bracket to simultaneously exhibit both flexible and strong characteristics that cannot be achieved with a single material, while maintaining manufacturing simplicity through the use of standard materials and processes.

AI summary
A bracket for securing a side airbag for an automotive vehicle is provided. The bracket includes a mounting plate formed of a synthetic resin material, and including a main body and a coupling part projecting from an upper surface of the main body and having a hole, and a bracket clip including two support plates in contact with front and rear surfaces of the coupling part and having through-holes in communication with the hole, and a bent part connecting the two support plates at each one side.Therefore, it is possible to protect the bracket to prevent damage to or deformation of the bracket when a bolt is screwed, thereby maintaining the side airbag in an optimal state.
