Multifunction Channel Frame Profile for Flexible Door-Jamb Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door frame assemblies lack flexibility in installation and adaptation to varying wall thicknesses, and often require fixed throat designs that restrict the positioning of hinges and latches.
Innovation Solution
A frame profile with a consistent cross-section that can be cut to form side and head jambs, featuring a main channel for receiving trim boards and hinges/latches, and a clip-on cover for covering unused sections, allowing adaptable installation and universal use across different wall thicknesses and door swing directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed throat design is used in traditional door frame assemblies, then the structure is simple and easy to manufacture, but the installation flexibility and adaptability to varying wall thicknesses is limited
Solution Approach 1:
The frame profile is designed as a universal component that can accommodate multiple functions: it serves as the structural jamb, contains a multifunction channel for receiving trim boards and positioning hinges/latches, and adapts to different wall thicknesses. This single integrated profile replaces multiple specialized components, enabling installation flexibility without proportionally increasing complexity
Solution Approach 2:
The frame profile is designed to be cuttable to required lengths, allowing segmentation of the continuous extrusion into custom-sized jambs. This segmentation capability enables adaptation to different wall thicknesses and installation locations while maintaining the benefits of a standardized extruded profile
2Adaptability or versatility
If traditional door frame assemblies use fixed positioning for hinges and latches, then the manufacturing process is straightforward, but the ability to adapt to different door swing directions and positions is restricted
Solution Approach 1:
The multifunction channel provides a dynamic positioning system where hinges and latches can be located at various positions along the channel length rather than being fixed at predetermined locations. This dynamic adaptability allows the same frame profile to accommodate different door swing directions and positions while maintaining manufacturing simplicity through a standardized extruded design
3Adaptability or versatility
If multiple separate components are used to achieve installation flexibility, then the adaptability improves, but the device complexity and number of parts increases
Solution Approach 1:
The patent merges multiple functions into a single integrated frame profile: the structural jamb, the multifunction channel for trim boards and hardware positioning, and the adaptation mechanism for different wall thicknesses are combined into one component. This consolidation achieves installation adaptability while reducing the total number of separate components that would otherwise be required

AI summary
A frame profile is an elongated extrusion having a consistent cross section along its length which can be cut to required lengths for forming side jambs and/or a head jamb of a door. The frame profile includes a base plate having a first face, a second face, a first side edge and a second side edge. There is a first formation extending from the first face adjacent the first side edge, and a second formation extending from the first face close to the second side edge. The second formation is spaced from the first formation to define a main channel therebetween. The second formation includes a trim receiving space for receiving a trim board therein.
