Ribbed Vehicle Underbelly Panels for Debris Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle underbelly structures lack effective protection against environmental factors and debris, particularly for recreational vehicles, as they fail to provide comprehensive shielding for components like water lines and tanks exposed at the bottom.
Innovation Solution
A protective panel apparatus is designed for vehicle chassis frames, featuring injection molded plastic panels with longitudinal ribs and a peripheral wall, configured to span across side beams, providing enhanced protection by resting on the beams and incorporating stiffeners for added structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If existing underbelly structures are used, then the vehicle has basic coverage, but the protection against environmental factors and debris is insufficient
Solution Approach 1:
The underbelly protection system is divided into multiple panels, each spanning between side beams. This segmentation allows for better coverage and protection of specific components while maintaining overall structural integrity.
Solution Approach 2:
The panel design incorporates vertical height by having the panel extend upward from the chassis frame, creating a three-dimensional protective barrier that shields components from debris and environmental factors approaching from below and sideways.
2Strength
If panels are designed to span across side beams, then structural support is improved, but the panel length and complexity increase
Solution Approach 1:
Ribs are strategically positioned at specific locations on the panel, particularly near the edges that rest on the side beams, to provide localized structural reinforcement where it is most needed for spanning across the beams without requiring uniform complexity throughout the entire panel.
Solution Approach 2:
The panel incorporates ribs as integrated structural elements within the panel material, creating a composite structure that combines the panel material with reinforcing ribs to achieve high strength-to-weight ratio and simplified installation as a single unit.
3Stability of the object's composition
If ribs are positioned inboard of the peripheral wall, then structural integrity is enhanced, but the panel design complexity increases
Solution Approach 1:
The ribs are pre-positioned inboard of the peripheral wall during panel manufacturing, creating a built-in structural reinforcement system that is integrated into the panel design from the outset, eliminating the need for separate reinforcement components or complex assembly procedures.

AI summary
A panel has a first edge portion defining a first end of the panel, and a second edge portion defining a second end of the panel. The length of the panel is predetermined for the panel to reach across a vehicle chassis frame in an installed position in which the first edge portion rests on a side beam and the second edge portion rests on an opposite side beam. The panel further has a longitudinal rib. A first end of the rib is located adjacent to, and inboard of, the first edge portion. A second end of the rib is located adjacent to, and inboard of, the second edge portion.
