One-Piece Garage Door Frame Profile for Straight Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing garage door frame profiles require complex assembly and are prone to misalignment, leading to jammed sectional doors due to small tolerances and deviations in perpendicularity, necessitating experienced installers and time-consuming installation processes.
Innovation Solution
A one-piece frame profile with a rectangular tubular main section, a plate-shaped fastening section, and a panel section, featuring grooves for secure sealing profile attachment and undercut grooves for easy fastening, allowing for precise alignment and straightforward assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple bent sheet metal parts are assembled to construct vertical columns and garage door frames, then the frame can be constructed with flexible components, but the assembly becomes time-consuming and requires experienced fitters due to alignment tolerances and perpendicularity deviations
Solution Approach 1:
The patent combines multiple separate frame components (vertical columns, horizontal frames, fastening elements) into a single integrated extruded profile. This one-piece construction eliminates the need for assembly operations, directly resolving the time-loss contradiction by removing alignment and fastening steps while maintaining structural functionality.
Solution Approach 2:
The extruded frame profile integrates multiple functions into a single component: structural support, fastening capability (via integrated fastening section), sealing (via groove for sealing profile), and panel attachment. This multi-functionality replaces what previously required multiple separate parts, reducing assembly complexity and time.
2Adaptability or versatility
If multiple bent sheet metal parts are assembled to construct vertical columns and garage door frames, then the frame can be constructed with flexible components, but the complexity of assembly increases and requires experienced fitters
Solution Approach 1:
The patent combines multiple separate frame components (vertical columns, horizontal frames, fastening elements) into a single integrated extruded profile. This one-piece construction eliminates the need for assembly operations, directly resolving the time-loss contradiction by removing alignment and fastening steps while maintaining structural functionality.
Solution Approach 2:
The frame is constructed from a homogeneous material (aluminum extrusion) with uniform properties throughout, eliminating the need to join dissimilar materials or components. This homogeneity simplifies the assembly process and reduces the skill level required for installation.
3Ease of manufacture
If separate frame components are used, then manufacturing of individual parts is simplified, but the overall frame assembly requires precise alignment and perpendicularity that increases installation difficulty
Solution Approach 1:
The patent combines multiple separate frame components (vertical columns, horizontal frames, fastening elements) into a single integrated extruded profile. This one-piece construction eliminates the need for assembly operations, directly resolving the time-loss contradiction by removing alignment and fastening steps while maintaining structural functionality.

AI summary
The invention relates to a profiled frame element for garage door frames, comprising a main section (12) and at least one groove (20, 22) that extends in the longitudinal direction of the profiled frame element and is used for suspending an elastic profiled seal (24). According to the invention, the main section (12) is shaped as a rectangular tube, and a fastening section (14) that extends at a right angle from the main section (12) as well as a covering section (16) which extends beyond the main section (12) are provided. The profiled frame element (10) is monolithic and can be used for garage door frames, for example.
