Profile Strip Arrangement with Metal Adhesion Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing profile strip arrangements for windshields are too expensive due to suboptimal material connections and adhesive properties, leading to inefficiencies in production and stability.
Innovation Solution
Incorporating a metal additional element in the connection area of the profile strip, either as a surface or a coating, to enhance adhesion properties and reduce material costs by using a surface section devoid of profile material, allowing for simpler and more resilient connections with the windshield.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a double-sided adhesive tape is used to connect the profile strip to the windshield, then the connection is simple and quick, but the connection strength and stability are insufficient
Solution Approach 1:
The patent combines plastic profile material with metal additional elements to create a composite connection structure. The metal elements (such as aluminum or steel strips) are integrated into the plastic profile strip, providing both structural support and improved adhesive properties. This composite approach allows the use of simple adhesive tapes while achieving superior connection strength and stability, as the metal components enhance the overall bonding capability compared to pure plastic materials.
2Strength
If adhesive is applied in free-flowing state to increase connection stiffness, then the connection becomes stiffer, but the production cost and complexity increase
Solution Approach 1:
The patent extracts the stiffness-enhancing function from the adhesive application process and transfers it to the metal additional elements integrated into the profile strip. Instead of relying on complex adhesive application procedures to achieve stiffness, the rigid metal components inherently provide the necessary structural rigidity. This simplifies the production process while maintaining connection stiffness.
3Reliability
If a metallic reinforcing insert is used to improve connection properties, then the adhesion improves, but the manufacturing cost increases
Solution Approach 1:
The patent merges the metal additional elements directly into the plastic profile strip during the extrusion or molding process. This integrated approach eliminates the need for separate assembly steps, reducing manufacturing complexity and cost. The metal elements are positioned and secured within the plastic matrix, creating a unified component that improves adhesion without requiring complex multi-step manufacturing procedures.
4Ease of manufacture
If the profile strip material is used directly for connection, then the production is simple, but the adhesion properties are suboptimal
Solution Approach 1:
The patent applies local quality enhancement by inserting metal elements specifically in the connection areas where adhesion is critical, while the rest of the profile strip maintains its simple plastic construction. This targeted approach improves adhesion properties at the connection points without complicating the overall manufacturing process or requiring metal components throughout the entire profile strip.
