Building Wall Panel System with Hidden Perimeter Extrusion Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional panel mounting systems for building walls often compromise weather tightness and aesthetics due to the use of rivets, which can lead to water and dirt penetration and visible rust, and they lack a clean, obscured fastening solution.
Innovation Solution
A panel system that utilizes perimeter extrusions connected to panels without penetrating rivets, featuring a connector extrusion with a retaining arm to inhibit lateral withdrawal and a filler strip for enhanced sealing, allowing for a clean and secure attachment to the building wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional rivet-based panel mounting systems are used, then panels can be securely attached to building walls, but visible fasteners and rust penetration occur compromising aesthetics and weather tightness
Solution Approach 1:
The patent extracts and removes the visible rivet fastening element from the final assembly. The mounting extrusion incorporates hidden fastening mechanisms that secure panels without exposing fasteners on the exterior surface, eliminating the source of rust and dirt penetration while maintaining secure attachment.
Solution Approach 2:
The mounting extrusion acts as an intermediary component between the panel and the building wall. It provides a hidden fastening interface that mediates the connection, preventing direct exposure of fasteners and thereby eliminating rust and dirt penetration pathways while maintaining structural integrity.
2Strength
If conventional rivet-based mounting systems are used, then panels can be attached to building walls, but visible fasteners compromise aesthetic appearance
Solution Approach 1:
The visible rivet fastener is extracted and removed from the exterior appearance. The mounting extrusion incorporates hidden fastening mechanisms that maintain secure panel attachment while eliminating visual disruption to the panel surface and building wall aesthetics.
Solution Approach 2:
The mounting extrusion serves as an intermediary that hides the fastening interface. It provides a clean transition between panel and wall without exposing fasteners, thereby preserving the aesthetic continuity of the building facade while maintaining secure attachment.
3Shape
If perimeter extrusions with intermediate recesses and filler strips are used, then a clean obscured fastening solution is achieved, but device complexity increases
Solution Approach 1:
The mounting extrusion merges multiple functions into a single integrated component: it provides structural support, houses hidden fastening mechanisms, creates the intermediate recess, and accommodates the filler strip. This consolidation achieves clean appearance while managing complexity through functional integration.
Solution Approach 2:
The mounting extrusion is designed as a multi-functional universal component that simultaneously provides mechanical attachment, aesthetic coverage, weather sealing, and structural support. This multi-functionality achieves clean appearance without proportionally increasing complexity, as one component performs multiple roles.
