Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glass partitioning systems face challenges in reliably supporting heavy and operative glass panels, particularly in double butt joint glass T-connections, which are difficult to fabricate and install and prone to failure if not done correctly.
Innovation Solution
A track system utilizing a horizontal extruded aluminum track profile with a central longitudinal channel and pre-scored frangible lines allows for easy creation of a double butt joint glass T-connection by allowing portions of the side walls to be cut and removed for insertion of a ninety-degree return track element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional extruded aluminum track systems are used for glass partitioning, then the system can support heavy glass panels, but the double butt joint glass T-connections are difficult to fabricate and install and prone to failure
Solution Approach 1:
The track system is divided into modular components: a main track and a return track that can be separately fabricated and then joined together. The pre-scored frangible lines allow the side walls to be segmented and removed to create windows for glass panel insertion. This modular approach makes the complex T-connection easier to manufacture and install while maintaining structural integrity.
Solution Approach 2:
The track elements are pre-formed with pre-scored frangible lines during manufacturing. These pre-scored lines are created in advance to allow easy cutting and removal of side wall portions during installation. This preliminary preparation simplifies the installation process and ensures consistent, reliable T-connections without requiring complex field modifications.
2Ease of operation
If pre-scored frangible lines are added to the track, then the side walls can be easily cut and removed for insertion, but the manufacturing process becomes more complex
Solution Approach 1:
The frangible lines are pre-scored during the extrusion or forming process, creating predetermined weak points in the track material. This preliminary action allows installers to easily cut and remove side wall portions by simply breaking at the pre-scored lines, significantly simplifying installation without requiring complex tools or procedures.
Solution Approach 2:
The track profile is designed with localized features: the frangible lines are positioned specifically at locations where side wall removal is needed, while other portions of the track maintain their full structural integrity. This localized modification allows easy installation at critical points without compromising the overall strength or complexity of the entire track system.
3Strength
If the track system is designed to support heavy operative panels, then structural strength is improved, but the fabrication and installation becomes more difficult
Solution Approach 1:
The track system uses segmented construction with distinct main track and return track components that can be separately fabricated to optimal specifications for load bearing, then assembled together. This segmentation allows each component to be optimized for strength while simplifying the manufacturing process compared to creating a single complex monolithic structure.
Solution Approach 2:
The track system utilizes composite construction combining extruded aluminum profiles with reinforcing elements and connection mechanisms designed specifically for load-bearing applications. This composite approach enables the track to support heavy operative panels while maintaining ease of fabrication and installation through standardized connection methods.
