Door Base Profile Bevel Shoulder Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door systems face challenges in securely connecting the carrier profile to the base profile, leading to potential accidental disconnection and safety hazards during assembly, as the carrier profile can be easily unhooked unintentionally, risking injury and damage to the system.
Innovation Solution
The base profile features a contact surface delimited by a bevel and a right-angled shoulder, with an obliquely upward groove serving as a screw channel, allowing the carrier profile to be easily hung and secured without additional components, using self-tapping screws that engage with the groove's threads for stable fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the carrier profile is hooked into the base profile for easy assembly, then the ease of operation is improved, but the reliability deteriorates because the carrier profile can be accidentally unhooked by simply lifting it
Solution Approach 1:
The base profile is prepared in advance with a screw channel (groove) that guides the screw during assembly. The contact surface with bevel and shoulder are pre-configured to receive the carrier profile. This preliminary preparation allows for easy assembly while ensuring reliable connection, as the screw is already positioned to engage both profiles when the carrier profile is hung on.
Solution Approach 2:
A screw acts as an intermediary element that connects the base profile and carrier profile. The screw engages with the screw channel in the base profile and the corresponding recess in the carrier profile, creating a secure mechanical connection that prevents accidental disconnection while maintaining ease of assembly through the guided engagement.
2Reliability
If additional components are used to secure the carrier profile to prevent accidental disconnection, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The screw channel (groove) is integrated directly into the base profile structure, merging the guiding function and the fastening function into a single component. This eliminates the need for separate guide rails or additional clamping mechanisms, reducing device complexity while maintaining reliable connection through the screw.
Solution Approach 2:
The base profile serves multiple functions: it provides the structural support, contains the screw channel for positioning and guiding the screw, and has the contact surface with bevel and shoulder for receiving the carrier profile. This multi-functionality reduces the need for additional specialized components, simplifying the overall device while ensuring reliable connection.
3Ease of manufacture
If the screw channel groove width is made smaller than the screw shank diameter to enable self-tapping, then the ease of manufacture is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The groove width is designed with specific dimensional parameters that are slightly smaller than the screw shank diameter. This parameter change enables the self-tapping action where the screw thread cuts into the groove walls during assembly. The precise but not overly tight tolerance allows for easy manufacture while providing sufficient guidance for the self-tapping process.

AI summary
The system has a sliding leaf (3) movably supported along a base profile (5), where a supporting profile (7) is mountable at the base profile. The supporting profile is fixed at the base profile by using a screw connection. The base profile has a groove comprising a screw that serves for fixing the base profile. The base profile has a contact surface for attaching the supporting profile, where the contact surface is limited by a bevel standing in an acute angle and by a shoulder. USE : Door system e.g. sliding door system. ADVANTAGE : The base profile has a contact surface for attaching the supporting profile, where the contact surface is limited by the bevel standing in acute angle and by the shoulder, thus providing a door system which is constructionally simple and simply operatable and providing a simple handling for the connection of the supporting profile at the base profile.
