Suspended Gas Generator Absorber for Airbag Thermal Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vehicle safety systems face complications in production due to the absorber being preassembled with the housing or retaining plate, making it difficult to thermally fix the airbag and complicating maintenance and repair, as the absorber cannot withstand oven temperatures required for this process.
Innovation Solution
The system features a gas generator connected to the absorber in a suspended manner, allowing for easy assembly and damping of vibrations, with the absorber not preassembled to the generator support or airbag retaining plate, enabling thermal fixation of the airbag without damaging the absorber and facilitating separate maintenance and replacement of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the absorber is firmly preassembled with the housing or retaining plate, then the absorber can effectively dampen vibrations, but the production process becomes complicated and the airbag cannot be thermally fixed
Solution Approach 1:
The system is divided into separate functional modules: the absorber is detached from the retaining plate, allowing independent assembly of the airbag-retaining plate unit and the absorber-gas generator unit. This segmentation enables the airbag to be thermally fixed to the retaining plate without the absorber being in the oven, while still achieving effective vibration damping when assembled together.
Solution Approach 2:
The airbag is thermally fixed to the retaining plate in advance before the absorber is attached. This preliminary action allows the thermal bonding process to occur without the absorber present, avoiding damage to the absorber from oven exposure while ensuring the airbag is securely attached before final assembly with the absorber.
2Reliability
If the absorber is firmly preassembled with the housing or retaining plate, then vibration damping is effective, but maintenance and repair become difficult
Solution Approach 1:
The absorber is designed as a separate detachable component from the retaining plate, allowing individual replacement of the absorber, gas generator, or airbag as needed. This modular segmentation enables maintenance personnel to replace only the faulty component without disassembling the entire system, significantly improving ease of repair while maintaining vibration damping effectiveness when assembled.
3Ease of manufacture
If the absorber is not preassembled with the retaining plate, then thermal fixation of the airbag is enabled, but the absorber must be attached in a subsequent step
Solution Approach 1:
The airbag is thermally fixed to the retaining plate in a preliminary step before the absorber is attached. This preliminary action simplifies the manufacturing process by enabling thermal fixation without the absorber present, avoiding damage to the absorber from high temperatures while maintaining a streamlined assembly process.
