Hybrid Window Snap-Fit Assembly for Moisture Infiltration

The patent removes mechanical fasteners and sealants from the connection process entirely. Instead, it uses a unified thermal-fusion welding method to join all component materials (vinyl, aluminum, wood), extracting the problematic intermediate connection elements that caused time delays and reliability issues.

The patent replaces the mechanical connection system (fasteners, screws, bolts) and chemical connection system (sealants, adhesives) with a thermal-fusion welding system. This substitution uses heat and pressure to create molecular-level bonds, eliminating the need for mechanical or chemical intermediaries.

The patent removes sealants from the connection process entirely. By using thermal-fusion welding to create continuous, monolithic joints between components, it eliminates the sealant layer that could potentially fail or deteriorate over time, thereby preventing moisture infiltration pathways.

The patent effectively creates a composite structure where previously separate materials (components connected by fasteners and sealants) become a unified, homogeneous joint through thermal fusion. This composite approach eliminates interfaces where moisture could penetrate, as the welded joint acts as a single continuous material barrier.

The patent creates a universal connection method (thermal-fusion welding) that can join all component materials (vinyl, aluminum, wood) using a single process and equipment type. This multi-functional approach replaces the need for different fastening and sealing systems, simplifying the overall connection system while maintaining adaptability to various materials.

The patent replaces the complex mechanical and chemical connection systems with a unified thermal-fusion welding system. This substitution consolidates multiple connection methods into one, reducing device complexity while maintaining the ability to connect different materials through controlled heat and pressure application.
