Composite Body Panels for Rust-Free Vehicle Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle body panel repair methods do not efficiently utilize fibrous materials like E-glass, carbon fiber, or Kevlar for replacing panels while ensuring ease of installation and painting, lacking in durability, rust resistance, and cost-effectiveness.
Innovation Solution
A lightweight body panel composed of multiple layers including a surfacing veil, first and second cloth layers of E-glass, and a customization layer of fiber glass, Kevlar, or carbon fiber, bonded with resin, which can be molded and customized for shape, size, and color to replace damaged panels without welding, using an adhesive for attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional metal body panels are used for vehicle repair, then structural strength is maintained, but the panels are heavy, prone to rust, and require welding which increases repair complexity and time
Solution Approach 1:
The patent uses fiber glass panels as a composite material alternative to traditional metal body panels. The fiber glass panels provide rust resistance while being lightweight, directly addressing the contradiction between reliability (rust resistance) and weight. The panels are made from fibrous sheet material that does not corrode like metal while maintaining structural integrity for vehicle body repair.
Solution Approach 2:
The fiber glass panels are designed as disposable replacement panels that are attached to the vehicle body and can be painted to match the vehicle. These panels eliminate the need for complex welding repairs and can be easily replaced if damaged, providing a cost-effective solution that trades long-term durability for ease of replacement and lower initial cost.
2Ease of manufacture
If traditional welding methods are used for body panel repair, then structural integrity is restored, but the repair process is complex, time-consuming, and requires specialized equipment
Solution Approach 1:
The patent replaces the mechanical welding process with a simpler attachment system. The fiber glass panels are attached to the vehicle body using adhesive or mechanical fasteners instead of welding, significantly simplifying the repair process while maintaining adequate structural integrity for body panels that are not load-bearing components.
Solution Approach 2:
The patent changes the fundamental parameter of how panels are joined to the vehicle body. Instead of using high-temperature welding processes, the panels are attached using low-temperature adhesive bonding or simple mechanical fastening, making the repair process accessible to non-specialists and eliminating the need for specialized welding equipment.
3Weight of moving object
If fiber glass panels are used for vehicle repair, then weight is reduced and rust resistance is improved, but the panels require specialized molding and surfacing processes
Solution Approach 1:
The patent applies preliminary action by pre-molding the fiber glass panels to the required shapes and sizes before they are installed on the vehicle. The panels are manufactured with predetermined contours and dimensions, eliminating the need for complex on-site molding operations. The surfacing veil is also pre-applied to facilitate easier painting and finishing after installation.
4Shape
If custom-colored panels are manufactured to match vehicle body, then aesthetic appearance is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent applies preliminary action by pre-applying a surfacing veil to the fiber glass panels during manufacturing. This veil creates a smooth surface that is ready for painting, and the panels can be painted to match the vehicle's existing color. This approach simplifies the manufacturing process compared to incorporating color pigments directly into the fiber glass matrix, while still achieving the desired aesthetic match.
Solution Approach 2:
The patent enables color changes by applying paint to the fiber glass panels after manufacturing. The panels are designed to be painted, allowing them to match the vehicle's existing color scheme. This post-manufacturing coloring approach is simpler than incorporating colorants during the fiber glass molding process, maintaining manufacturing simplicity while achieving aesthetic compatibility.
