Automotive Seat Riser Layered Structure Abrasion Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat systems do not effectively manage space utilization when seats are removed, as the riser/latch assemblies can cause abrasive wear and noise during storage due to direct contact with the ground surface.
Innovation Solution
A removable vehicle seat system with a riser having a layered structure comprising a metal layer and a non-metal layer, where the non-metal layer wraps around the metal layer's edge to form a sliding or contact surface, providing abrasion resistance and noise isolation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the riser/latch assembly is made of metal for structural integrity, then strength is improved, but abrasive wear and noise increase during storage
Solution Approach 1:
The riser assembly uses a composite structure with a metal layer providing structural strength and a non-metal layer (such as plastic or polymer) wrapping around the metal layer to form the sliding surface. This composite approach allows the metal core to maintain structural integrity while the non-metal outer layer reduces abrasive wear and noise when the seat is stored on the ground surface.
Solution Approach 2:
The solution applies different material properties to different parts of the riser assembly. The inner metal layer provides overall structural strength, while the outer non-metal layer specifically addresses the contact surface that interacts with the ground during storage. This localized application of different material qualities resolves the contradiction between strength and wear resistance.
2Object-affected harmful factors
If a protective coating is applied to reduce wear, then abrasive wear is reduced, but manufacturing complexity increases
Solution Approach 1:
Rather than applying a separate protective coating to a metal surface, the invention integrates the protective non-metal layer as part of the riser assembly's core structure. The non-metal layer is formed concurrently with the metal layer in a single manufacturing process, eliminating the need for additional coating steps and reducing manufacturing complexity while still providing wear protection.
