Removable Airbag Bracket for Easy Vehicle Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing airbag units are difficult to install and remove due to their location on the forward side of the cowl top and the length corresponding to the vehicle width, which complicates installation and removal processes.
Innovation Solution
An airbag unit design that includes an airbag covering the hood or windshield, a gas generator, a cover bottom member, a cover lid member, and a bracket removably supported by the vehicle body, with a stopper to prevent deformation and a central portion elevation to secure engine room space, allowing easy assembly and disassembly by attaching the bracket to the vehicle body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the airbag unit is located on the forward side of the cowl top with length corresponding to the vehicle width, then the airbag can effectively cover the hood and windshield area, but the installation and removal becomes troublesome and complex
Solution Approach 1:
The airbag unit is divided into separable components: the airbag module itself and the bracket assembly. The bracket is detachably coupled to the vehicle body, allowing the airbag unit to be installed or removed as a complete module without complex disassembly. This segmentation resolves the contradiction by enabling easy installation/removal while maintaining proper positioning for effective coverage.
Solution Approach 2:
A bracket is introduced as an intermediary component between the airbag unit and the vehicle body. The bracket provides a simplified attachment interface that facilitates easy installation and removal while ensuring the airbag unit is properly positioned to cover the hood and windshield area effectively.
2Ease of operation
If the bracket is removably supported by the vehicle body, then the airbag unit can be easily installed and removed, but the structural stability during airbag expansion may be compromised
Solution Approach 1:
The bracket is designed with predetermined attachment positions and coupling mechanisms that ensure optimal structural support is established before airbag deployment. The removable coupling maintains strength during expansion while allowing easy installation and removal when the vehicle is not in use.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy installation and removal of the airbag unit, prevents deformation during expansion, and secures a larger space under the hood for the engine room, while effectively covering the hood and windshield during deployment.
Implementation Method 1
