Composite Textile Structure for Vehicle Trim Fragment Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing textile structures for motor vehicle compartments do not effectively mitigate the spread of fragments under impact loads and require separate components for sound insulation and fragment protection, which are inefficient in terms of space, material, and assembly.
Innovation Solution
A composite textile structure integrating a sound-insulating layer and a fragment protection layer, connected via an adhesive or thermoplastic bonding, allowing for dual functionality and reduced component size, adaptable to various contours, and simplified assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate sound-insulating layer and fragment protection layer are used, then sound insulation and fragment protection functions are achieved, but device complexity and assembly steps increase
Solution Approach 1:
The patent combines the sound-insulating layer and fragment protection layer into a single integrated textile structure. The textile structure includes both functional layers working together to provide sound insulation and fragment protection simultaneously, eliminating the need for separate components and reducing assembly complexity.
Solution Approach 2:
The textile structure is designed to perform multiple functions: sound insulation, fragment protection, and adaptability to different contours. By integrating these functions into a single structure, the patent achieves multi-functionality without requiring separate dedicated components for each function.
2Reliability
If separate sound-insulating layer and fragment protection layer are assembled separately, then each layer can be optimized independently, but assembly time and production efficiency decrease
Solution Approach 1:
The sound-insulating layer and fragment protection layer are merged into a single textile structure that can be manufactured as one integrated component. This allows both layers to be optimized together during manufacturing while enabling single-step assembly, thereby improving production efficiency without sacrificing functional optimization.
3Reliability
If multiple separate layers are used behind cladding element, then comprehensive protection is achieved, but available space is consumed
Solution Approach 1:
The patent merges multiple protective layers into a single integrated textile structure that provides both sound insulation and fragment protection. This consolidation maintains comprehensive protection effectiveness while significantly reducing the total volume required behind the cladding element compared to using separate layers.
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
The composite structure effectively absorbs sound waves and reduces fragment dispersion, optimizing space and material usage while simplifying assembly, enhancing both sound insulation and fragment protection without increasing component size or complexity.
Implementation Method 1
The textile structure (12) can be attached to the cladding element (10) by means of an adhesive layer (34, 46, 58, 600)
Implementation Method 2
The connecting layer (33, 44, 64) can be made of material that melts when heat is applied for the connecting layer, such as a hot-melt adhesive or a thermoplastic
