Plastic Component Anchoring Section Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in the automotive sector is to simplify and expedite the production of fiber-reinforced plastic components by establishing a stable and secure connection between the base body and holding elements, as existing methods like gluing or drilling complicate the process and weaken the components.
Innovation Solution
A plastic component with a base body and holding element featuring an anchoring section formed by interconnected balls, which is embedded or integrated into the base body in a form-fitting and material-locking manner, allowing for a reliable connection without additional post-processing steps, and enabling the holding section to be assembled after production, thus maintaining a smooth surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If retaining elements are attached by welding or soldering to plastic components, then the connection strength is improved, but the manufacturing complexity increases and additional processing steps are required
Solution Approach 1:
The retaining element and base body are merged into a single integrated component during the molding process. The retaining element is formed directly as part of the base body structure, eliminating the need for separate attachment operations like welding or soldering, while maintaining strong mechanical connection.
Solution Approach 2:
The retaining element is pre-formed within the base body during the initial molding process. The cavities and structural features for the retaining element are created simultaneously with the base body, so no additional processing steps are needed later to attach or prepare the retaining element.
2Device complexity
If retaining elements are glued onto the plastic component, then the manufacturing process is simplified, but the connection strength becomes insufficient
Solution Approach 1:
The retaining element is combined with the base body as an integral structure formed during molding. This merging provides both mechanical strength through the solid plastic material and manufacturing simplicity through the single-step formation process, overcoming the weaknesses of both separate attachment methods.
