Airbag Chute Panel Molding Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional passenger airbag chute panel manufacturing processes are inefficient due to the need for welding separate components, resulting in a heavy panel and lengthy manufacturing time, as well as the requirement for expensive equipment.
Innovation Solution
A method of manufacturing a chute panel where a substrate is formed with a void, and a chute and chute door are molded onto and within the substrate, eliminating the need for separate components and welding by integrating them during the molding process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the substrate and chute are formed as two separate parts and welded together, then the structural integrity is maintained, but the panel becomes relatively heavy and the manufacturing time increases
Solution Approach 1:
The substrate and chute are merged into a single integrated component formed by molding the chute directly onto the substrate body. This eliminates the need for separate parts and welding, reducing panel weight while maintaining structural integrity through the molded connection.
2Strength
If welding is used to couple the substrate and chute, then the components are securely joined, but the manufacturing time becomes lengthy and expensive equipment is required
Solution Approach 1:
The substrate and chute are formed as a single integrated component through molding, eliminating the welding process entirely. This significantly reduces manufacturing time and eliminates the need for expensive welding equipment while maintaining secure joining through the molded connection.
3Strength
If welding is used to join the substrate and chute, then the components are securely connected, but the cost of equipment and manufacturing process increases
Solution Approach 1:
The substrate and chute are integrated into a single molded component, eliminating the need for welding equipment and processes. This reduces manufacturing costs while maintaining secure component connection through the molded joint.
4Strength
If separate components are welded together, then the assembly is structurally sound, but the manufacturing complexity increases
Solution Approach 1:
The substrate and chute are combined into a single integrated component formed through molding, eliminating the need for separate component fabrication and welding operations. This simplifies the manufacturing process while maintaining structurally sound assembly.

AI summary
A method of manufacturing a chute panel of an airbag assembly. The method comprises forming a substrate from a first material to have a body having first and second ends and a longitudinal axis extending therebetween and a void residing in the body. The method further comprises forming a chute and a chute door from a second material. The chute comprises a base molded onto the substrate body and one or more sidewalls extending from the base. And wherein forming the chute door comprises filling the void in the substrate body with the second material to form the chute door.
