Door Leaf Clamping Mechanism for Aesthetic Panel Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional door manufacturing methods face challenges such as raised edges interfering with aesthetics, increased production time due to sawing off profile lips, and the need for precise gluing in controlled conditions, which are time-consuming and require experienced personnel.
Innovation Solution
A door leaf design featuring a frame with inward-oriented lips that uses clamping means with basic elements and clamping arms to secure the front panel without gluing, allowing for easier alignment and faster installation, using standard profiles and reducing the need for specialized conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the lip of the profiles is used to form a groove for panel mounting, then the panel can be secured to the frame, but the lip creates a raised edge that interferes with the aesthetic appearance of the door
Solution Approach 1:
The invention extracts the panel securing function from the profile lip itself by introducing a separate mounting plate that interfaces with the lip. The mounting plate has a recess that receives the lip, allowing the panel to be secured without the lip being visible on the front surface of the door, thus resolving the contradiction between securing strength and aesthetic appearance.
2Shape
If the lip is sawn away to allow the front leaf to cover the frame completely, then a modern taut appearance is achieved, but extra working time is required which increases production cost
Solution Approach 1:
The mounting plate is pre-formed with the appropriate recess geometry that accommodates the profile lip. This preliminary preparation eliminates the need for on-site sawing operations, as the mounting plate arrives ready-to-install and simply needs to be attached to the frame, significantly reducing production time while maintaining the aesthetic appearance.
3Shape
If the front panel is glued to the frame, then a taut even appearance is obtained, but the gluing process requires controlled conditions, clamps, and experienced personnel which increases complexity and time
Solution Approach 1:
The invention replaces the chemical bonding process (gluing) with a mechanical fastening system. The mounting plate provides mechanical attachment points that secure the front leaf to the frame through screws or other fasteners, eliminating the need for adhesive application, clamping, and controlled drying conditions, thus reducing process complexity while maintaining the taut even appearance.

AI summary
Disclosed is a door leaf including a frame and a door panel with a front leaf, a back leaf and a filler plate. The frame includes conventional profiles with a lip oriented inwards to form a groove. The front leaf is affixed against the front of the frame, and at least partially covers the front of the frame. The door panel is fastened to the back of the frame by panel slats. The front leaf is provided with clamp that enable the front leaf to be pulled against the front of the frame, whereby these clamps are formed by one or more clamps along the periphery of the frame with a basic element that is fastened on the front leaf and a clamping slat affixed thereon that hooks behind an aforementioned lip and can be tightened on the basic element towards the front leaf.
