Solution Overview
Problem
Existing window assemblies for vehicles face challenges in efficiently defogging or defrosting window panels, particularly when the electrical connections are unreliable or difficult to maintain, especially during the soldering process.
Innovation Solution
The use of a magnetic electrical connector held by an electromagnet allows for precise and secure attachment of the electrical connector to the window panel, ensuring reliable electrical connection to the heater grid or other conductive elements, enabling defogging or defrosting regardless of the movable window's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soldering methods are used to connect the electrical connector to the window panel, then the electrical connection can be established, but the connector positioning accuracy and connection reliability are compromised during the soldering process
Solution Approach 1:
The electromagnet is used to pre-position and securely hold the electrical connector at the attaching region before the soldering process begins. This preliminary positioning ensures the connector remains accurately located throughout the soldering operation, eliminating positioning drift and improving both manufacturing precision and connection reliability.
Solution Approach 2:
The electromagnet acts as an intermediary device between the electrical connector and the window panel during the soldering process. It provides a controllable magnetic holding force that secures the connector in place, allowing for precise positioning and stable connection without requiring mechanical fixtures or complex positioning mechanisms.
2Reliability
If the electrical connector is securely held during soldering, then connection reliability improves, but the device complexity increases due to the addition of an electromagnet
Solution Approach 1:
The electromagnet replaces traditional mechanical positioning systems, clamps, or fixtures that would otherwise be needed to hold the electrical connector during soldering. By using magnetic fields instead of mechanical components, the system achieves secure connector attachment with simpler overall device architecture, reducing mechanical complexity while improving reliability.
