Sliding Door Seal Mounting Profile Without Groove Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sealing technologies for sliding doors require grooves in the door leaf, which facilitate moisture penetration and reduce sound insulation, and are time-consuming to install.
Innovation Solution
A sealing unit comprising a mounting profile that attaches to the door or wall element without a groove, featuring a recess for a sealing profile that can be easily installed and replaced, with a retaining element to secure the sealing profile in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a groove is created in the door leaf for mounting the sealing profile, then the sealing profile can be securely attached, but moisture penetration increases and sound insulation decreases
Solution Approach 1:
The sealing system is divided into two separate components: a mounting profile that attaches to the door leaf, and a sealing profile that attaches to the mounting profile. This segmentation eliminates the need for grooves in the door leaf, as the mounting profile can be surface-mounted using adhesive or mechanical fasteners, thereby preventing moisture penetration and maintaining sound insulation while still providing secure attachment for the sealing profile.
2Reliability
If a groove is created in the door leaf for mounting the sealing profile, then the sealing profile can be securely attached, but the installation process becomes time-consuming
Solution Approach 1:
By separating the mounting function from the sealing function into distinct profiles, the installation process is simplified. The mounting profile can be pre-installed on the door leaf surface without requiring groove creation, and the sealing profile can then be easily attached to the mounting profile. This eliminates the time-consuming groove creation step while maintaining secure attachment.
Solution Approach 2:
The mounting profile is designed to be pre-installed on the door leaf surface before the sealing profile is attached. This preliminary action eliminates the need to create grooves during the final installation process, significantly reducing installation time while ensuring secure attachment of the sealing profile.
3Reliability
If the sealing profile is directly attached to the door or wall element, then secure mounting is achieved, but replacement becomes difficult
Solution Approach 1:
The system separates the permanent mounting function (mounting profile attached to door leaf) from the replaceable sealing function (sealing profile attached to mounting profile). The sealing profile can be easily removed and replaced by detaching it from the mounting profile, while the mounting profile remains securely fixed to the door leaf. This segmentation enables simple replacement without affecting the mounting structure.
Solution Approach 2:
The mounting profile serves as an intermediary component between the door leaf and the sealing profile. This intermediary structure allows the sealing profile to be easily attached and detached from the mounting profile without requiring removal from the door leaf itself, facilitating simple replacement while maintaining secure overall mounting.

Function Achieved in This Case
Enables installation and replacement of seals without grooves, improving moisture resistance and sound insulation while simplifying the installation process.
Implementation Method 1
The retaining element has a spring-loaded part that is held in place by the mounting profile when the sealing unit is mounted on the door or wall element

AI summary
A sealing unit comprises a mounting profile (2) for attaching the sealing unit to a door (F) or a wall element (W) and a sealing profile (1) for sealing a gap between a movable door leaf or door wing (F) and a door frame of the door or the wall element (W). The mounting profile (2) has a rear surface (200) for contact with the door or wall element. The sealing profile (1) has a retaining element (12), and the mounting profile (2) has a recess (23) for receiving the retaining element (12). The recess (23) is closed on a front surface (201) of the mounting profile (2) opposite the rear surface (200). The sealing unit according to the invention enables the installation of a seal without the use of grooves.
