Insulating Skid Plate Structure for Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional skid plates fail to effectively distribute concentrated loads and provide thermal protection for vehicle underbody components, potentially causing damage and inefficient energy consumption due to lack of insulation.
Innovation Solution
A two-layer skid plate design comprising a metallic first layer and a rigid foam second layer, where the foam layer converts concentrated loads into distributed loads and provides thermal insulation, with the foam layer being compressible to absorb excess energy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional metal skid plate is used to protect underbody components, then physical protection is provided, but concentrated loads are not effectively distributed and thermal protection is not provided
Solution Approach 1:
The skid plate is divided into two distinct layers: a rigid metal first layer for structural strength and debris contact, and a compressible foam second layer for load distribution and thermal insulation. This segmentation allows each layer to perform its specialized function, resolving the contradiction between physical protection and load distribution capability
Solution Approach 2:
The invention combines two different materials (metal and foam) into a composite structure where the metal layer provides rigidity and protection while the foam layer provides compressibility for load distribution and thermal insulation properties, thereby achieving both physical protection and thermal protection simultaneously
2Force
If pre-formed supports are used to distribute concentrated loads, then some load distribution is achieved, but debris is trapped between the skid plate and underbody components
Solution Approach 1:
The foam second layer acts as a flexible, conformable element that can deform under concentrated loads while maintaining contact with the underbody component. This flexibility prevents debris entrapment by allowing the skid plate to conform to the component surface without creating gaps where debris could be trapped, while still distributing the load through the compressible foam material
3Reliability
If an airgap is used to minimize physical damage, then some protection is provided, but concentrated loads are not effectively distributed and thermal protection is not provided
Solution Approach 1:
The foam second layer serves as an intermediary element between the metal skid plate and the underbody component. It provides thermal insulation to protect the component from heat while maintaining mechanical contact for load distribution, and its compressible nature allows it to absorb impact energy, thereby providing physical damage protection without requiring an airgap
4Strength
If a rigid metal plate is used to absorb concentrated loads, then structural strength is maintained, but the plate deforms and underbody components may be damaged
Solution Approach 1:
The compressible foam second layer is positioned between the rigid metal first layer and the underbody component to act as a cushioning element. When concentrated loads are applied, the foam compresses to absorb impact energy before it can be transmitted to the underbody component, thereby protecting the component while the rigid metal layer maintains its structural strength and resists deformation

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 skid plate effectively minimizes physical damage to underbody components by distributing loads and reduces energy consumption for thermal management, enhancing vehicle range and efficiency.
Implementation Method 1
the second layer may be compressible to absorb energy generated by a contact to the first layer of the skid plate

AI summary
A skid plate for a vehicle includes a first layer, including a first material and a second layer, including a second material, which may be different from the first material. The second layer may be attached or bonded to the first layer and may convert a concentrated load into a distributed load. The second layer may provide thermal insulation for at least one underbody component of the vehicle. For example, the first layer may be metallic, while the second layer may be a rigid foam. The rigid foam may include an expanding adhesive foam. An adhesive may be disposed between the first layer and the second layer, to attach or bond the first layer to the second layer. The second layer may be adjacent to at least one underbody component of the vehicle. The concentrated load may correspond with a contact to the first layer of the skid plate.
