Dashboard Cladding Part with Reinforcing Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motor vehicle dashboards lack sufficient structural reinforcement, failing to protect units such as fuse boxes and glove compartments from damage due to their flexible structure, which is not resistant to external forces.
Innovation Solution
A cladding part with a reinforcing layer made of hard plastic, incorporating a damping layer, shaped portions for secure storage, and fixing means to prevent slipping and rattling, integrated into the dashboard's lower region to provide enhanced protection and storage capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a flexible structure is used for the cladding part, then ease of manufacture is improved, but strength and protection capability deteriorate
Solution Approach 1:
The cladding part is constructed as a composite structure with an outer skin made of flexible material (thermoplastic elastomer or thermoplastic polymer) and an inner core made of foam material. This combination provides both the ease of manufacture associated with flexible materials and the strength protection capability provided by the rigid foam core, directly resolving the technical contradiction between manufacturability and structural strength.
2Strength
If a rigid structure is used for the cladding part, then strength and protection capability are improved, but ease of manufacture deteriorates
Solution Approach 1:
The foam core provides the necessary rigidity and strength for protection, while the outer skin of thermoplastic material can be easily molded and manufactured. The composite structure allows each material to contribute its optimal properties, making the overall component easier to manufacture than a fully rigid structure while maintaining high strength.
Solution Approach 2:
The outer skin is designed as a thin flexible shell made of thermoplastic elastomer or polymer that can be easily formed and attached to the foam core. This thin flexible outer layer simplifies manufacturing processes compared to creating fully rigid structures, while the underlying foam provides the structural strength.
3Object-generated harmful factors
If sound-absorbing material is used for the cladding part, then noise reduction is improved, but structural stability deteriorates
Solution Approach 1:
The foam core material serves dual functions: it provides structural stability and rigidity to maintain the dashboard's structural integrity, while simultaneously acting as a sound-absorbing material to reduce noise. The outer skin layer contributes to noise reduction through its damping properties. This composite structure resolves the contradiction by integrating both structural and acoustic functions into a single integrated component.
