Door Seal Bracket with Stop for Flush Groove Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seals that protrude over the edge of a groove for attachment to a door leaf require the door to be unhinged for assembly or disassembly, limiting ease of positioning and installation.
Innovation Solution
A seal design featuring a mounting bracket with a stop arranged in a plane parallel to the second leg, allowing the seal to be positioned flush with the groove edge, and a fastening structure that enables easy attachment and detachment without requiring the door to be unhinged, using a hat profile or U/H-shaped housing with stops for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the seal is mounted with the housing completely within the groove and flush with the lower edge, then sound insulation is improved, but the seal cannot be easily positioned and installed
Solution Approach 1:
The mounting bracket is divided into two functional legs: a first leg for attachment to the door leaf and a second leg for connection to the housing. This segmentation allows the positioning function (second leg with stop) to be separated from the attachment function (first leg), enabling easy installation while maintaining proper housing positioning for sound insulation.
Solution Approach 2:
The mounting bracket acts as an intermediary component between the door leaf and the seal housing. It provides the stop feature for easy positioning while connecting to the housing, allowing the housing to be positioned flush with the groove edge for sound insulation without requiring complex installation procedures.
2Manufacturing precision
If the seal has outwardly flared legs that protrude beyond the groove edge for attachment, then positioning precision is improved, but the seal protrudes significantly and sound insulation deteriorates
Solution Approach 1:
The mounting bracket is divided into two functional legs: a first leg for attachment to the door leaf and a second leg for connection to the housing. This segmentation allows the positioning function (second leg with stop) to be separated from the attachment function (first leg), enabling easy installation while maintaining proper housing positioning for sound insulation.
Solution Approach 2:
The stop is arranged in a plane parallel to the plane in which the second leg lies, creating a spatial relationship where the stop provides positioning in one dimension while the leg connection provides attachment in another dimension. This allows precise positioning without the legs protruding beyond the groove edge.
3Strength
If the seal uses holes in the legs for screw or nail fastening, then attachment strength is improved, but the door leaf must be removed for assembly or disassembly
Solution Approach 1:
The mounting bracket is pre-formed with the stop feature and connection structures during manufacturing. This preliminary preparation allows the bracket to be simply positioned and attached to the door leaf without requiring the door to be removed, while still providing strong attachment through the first leg.
Solution Approach 2:
The mounting bracket enables dynamic installation and removal of the seal without requiring door disassembly. The bracket itself can be attached and detached from the door leaf independently, allowing the seal to be installed or removed by simply manipulating the bracket rather than the entire door assembly.

AI summary
Seal comprising a housing (1) and at least one mounting bracket (2) for attaching the housing (1) and thus the seal to a door leaf (T) or the like, wherein the seal (1) has at least one stop (12, 24) by which the seal can be positioned such that, in a state of the seal being mounted on a door leaf (T), the housing (1) of the seal does not protrude or only protrudes slightly beyond an edge (K) of the groove.
