Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a prefabricated, reusable temporary barrier that provides fire, smoke, and sound protection during construction and remodeling projects, while meeting stringent fire code regulations such as ASTM E-84 and E-119 performance requirements.
Innovation Solution
A barrier system comprising interlocking panels with a tongue and groove assembly and a panel lock mechanism, featuring a peripheral frame with magnesium oxide strips, steel side faces, and insulation blocks with radiant barriers, which can be easily assembled and customized to fit various spaces, providing airtight joints and meeting fire-rated protection standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a temporary barrier is constructed on-site from wood or gypsum panels, then the barrier can be customized to fit the space, but the installation time and labor requirements increase significantly
Solution Approach 1:
The barrier is divided into modular prefabricated panels that can be independently manufactured and then quickly assembled on-site. Each panel is a self-contained unit with integrated framing, insulation, and finishing surfaces, eliminating the need for time-consuming on-site construction while maintaining customization through panel selection and configuration.
Solution Approach 2:
The barrier panels are completely fabricated and prepared in advance during manufacturing, including all structural components, insulation layers, and finishing surfaces. This preliminary action removes the complex construction process from the on-site installation phase, reducing installation time while allowing for custom designs to be pre-engineered during manufacturing.
2Loss of time
If a prefabricated reusable barrier is used, then installation time is reduced, but achieving fire code compliance becomes more difficult
Solution Approach 1:
The barrier panels utilize composite construction combining multiple materials with complementary properties: fire-resistant framing members, insulation materials with fire-retardant properties, and fire-tested panel assemblies. These composite structures are designed to meet or exceed fire code requirements while maintaining the speed advantages of prefabricated construction.
Solution Approach 2:
The barrier design incorporates specific material specifications and construction parameters that are optimized for fire resistance, such as minimum thickness requirements, fire-rated insulation densities, and specific fire-testing certifications. These parameter changes ensure fire code compliance while preserving the time-saving benefits of prefabricated modular construction.
3Ease of operation
If conventional temporary barriers are used, then they can be easily installed, but they do not provide adequate fire and smoke protection
Solution Approach 1:
The barrier system uses standardized modular panels that maintain ease of installation through simple handle-based lifting and positioning mechanisms. The segmentation into uniform, pre-engineered units allows for quick assembly while each unit is designed with integrated fire protection layers, achieving both ease of installation and adequate fire/smoke protection.
Solution Approach 2:
The barrier panels incorporate specific fire protection parameters including fire-rated insulation materials, fire-resistant framing constructions, and surface treatments that provide fire and smoke resistance. These parameter changes are built into the prefabricated structure, allowing conventional ease of installation while significantly improving fire and smoke protection capabilities.

AI summary
A barrier system for partitioning a space includes panels which interlock with each other to provide a barrier that is fire rated. The interlocking panels are assembled in the barrier in columns using a tongue and groove assembly and a panel lock using a strike and latch supported by the tongue member and groove member, respectively. Each panel includes a peripheral frame (that is shaped to provide the tongue and groove members), opposed steel side faces mounted to the peripheral frame, and an insulation block filling an interior space delimited by the peripheral frame and the opposed steel side faces. The insulation block includes a pair of insulating material layers that sandwich a radiant barrier layer. A floor module supports a bottom edge of the panel and an interface module supports a side/top edge of the panel. The floor/interface modules are configured with telescoping sections and are length trimmable.
