Vehicle Panel Part With Closed Hollow Profile Load Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paneling parts for vehicles are difficult to produce efficiently and cost-effectively, and they often struggle to withstand dynamic and static loads while maintaining a visually appealing design.
Innovation Solution
A paneling part design featuring a carrier part and a design part with a support structure that forms a closed hollow profile, where the carrier part is attached via a material bond through the support structure, and a connecting section with reduced material thickness to prevent visible markings, allowing for easy installation and strong connections using plastic injection molding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a two-component process is used to manufacture paneling parts with a carrier part and design part, then the structural strength and load-bearing capacity are improved, but the manufacturing complexity and production cost increase
Solution Approach 1:
The patent combines the carrier part and design part into a single integrated component manufactured in one injection molding process. The support structure of the carrier part is designed to directly receive and bond with the design part, eliminating the need for separate manufacturing steps and assembly operations while maintaining structural strength.
Solution Approach 2:
The carrier part is designed with a universal support structure that serves multiple functions: providing structural strength, forming bonding surfaces for the design part, and enabling direct integration during a single molding process. This multi-functional design reduces manufacturing complexity while maintaining load-bearing capacity.
2Strength
If the support structure has sufficient material thickness to ensure strength, then the connection strength is improved, but the risk of visible markings on the design part increases
Solution Approach 1:
The support structure features locally varied material thickness with thicker regions providing bonding surfaces for strong connections and thinner regions that minimize visible markings on the design part. This local quality variation allows the structure to achieve both connection strength and aesthetic quality simultaneously.
Solution Approach 2:
The patent addresses the conflict between thickness and markings by transitioning to a different dimensional approach - creating a support structure with controlled thickness variations that prioritize aesthetic quality on the visible surfaces while maintaining sufficient thickness in bonding regions for connection strength.
3Adaptability or versatility
If multiple separate components are used for the carrier part and design part, then the manufacturing flexibility is improved, but the installation time and assembly complexity increase
Solution Approach 1:
The carrier part and design part are merged into a single integrated component manufactured in one injection molding process. The support structure is designed with built-in bonding surfaces that directly receive the design part, eliminating separate assembly steps and reducing installation time while maintaining manufacturing flexibility through modular design options.
