Window Profile Lateral Fitting Groove
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional window and door profiles with fitting part grooves have aesthetics and energy efficiency issues due to protruding fittings and unsightly grooves, which require a visible airgap and compromise visual appeal.
Innovation Solution
The fitting part groove is positioned behind the rebate surface with a non-parallel opening, such as orthogonal to the main plane, allowing fittings to be hidden, reducing the rebate clearance and enhancing aesthetics by eliminating visible grooves, and optionally using a cover for protection and attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the fitting part groove is arranged on the rebate surface with parallel opening, then fittings can be accommodated, but fittings protrude into the airgap area and create visible unsightly grooves
Solution Approach 1:
The fitting part groove is repositioned from a parallel arrangement on the rebate surface to a lateral arrangement behind the rebate surface, changing the spatial dimension of groove placement. This dimensional shift allows the groove opening to face the front or rear side of the profile instead of the rebate surface, eliminating protrusion into the airgap area while maintaining fitting accommodation functionality
Solution Approach 2:
The fitting part groove is nested behind the rebate surface within the profile structure, with the groove opening facing the front or rear side. This nesting arrangement hides the groove and fittings from the rebate side view, eliminating the need for a large airgap while preserving the fitting accommodation function
2Ease of operation
If fittings are arranged in the airgap area, then functional elements can be driven, but the rebate clearance must be larger reducing energy efficiency
Solution Approach 1:
The fitting part groove is repositioned from a parallel arrangement on the rebate surface to a lateral arrangement behind the rebate surface, changing the spatial dimension of groove placement. This dimensional shift allows the groove opening to face the front or rear side of the profile instead of the rebate surface, eliminating protrusion into the airgap area while maintaining fitting accommodation functionality
Solution Approach 2:
The fitting part groove is nested behind the rebate surface within the profile structure, with the groove opening facing the front or rear side. This nesting arrangement hides the groove and fittings from the rebate side view, eliminating the need for a large airgap while preserving the fitting accommodation function
3Ease of manufacture
If the fitting part groove is visible on the rebate side, then fitting attachment is straightforward, but the visual appeal and surface continuity are compromised
Solution Approach 1:
The fitting part groove is repositioned from a parallel arrangement on the rebate surface to a lateral arrangement behind the rebate surface, changing the spatial dimension of groove placement. This dimensional shift allows the groove opening to face the front or rear side of the profile instead of the rebate surface, eliminating protrusion into the airgap area while maintaining fitting accommodation functionality
Solution Approach 2:
The fitting part groove is nested behind the rebate surface within the profile structure, with the groove opening facing the front or rear side. This nesting arrangement hides the groove and fittings from the rebate side view, eliminating the need for a large airgap while preserving the fitting accommodation function

AI summary
The profiles e.g. wing profile (21), has a fitting part nut (22) sectionally arranged behind a rebate surface (23) in the profile. A nut opening is provided at front and rear sides of the profile, which is formed from plastic, aluminum or wood. A cover (26) is removably attached to the profile and covers the fitting part nut. The fitting part nut extends over an entire length of the profile. A fitting part (24) i.e. connecting rod fitting part, is attached to a side wall (25) of the fitting part nut using a screw, a clip or an adhesive bonding part.
