Door Blade Glazing via Direct Adhesive Bonding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for glazing doors are complex and time-consuming, requiring adjustments to insulation and the use of peripheral wooden strips, which complicates the production process and increases costs.
Innovation Solution
A method involving creating an opening in the door blade without a wooden strip or insulation lining, filling the slot between the glazed unit and the door blade with adhesive to form a strong joint, allowing for flexibility in shape and simplifying the manufacturing process, and optionally using a reinforcing layer like a fibre-glass net for enhanced security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the traditional method using peripheral wooden strips and insulation adjustment is used, then the glazed unit is securely fitted, but the production process becomes complex and time-consuming
Solution Approach 1:
The patent removes the peripheral wooden strip and insulation lining from the traditional glazing method. By extracting these intermediate components, the glazed unit is placed directly into an opening created in the door blade, significantly simplifying the production process while maintaining secure fitting through direct adhesive bonding between the glazed unit and door blade
Solution Approach 2:
The patent merges the functions of the wooden strip, insulation lining, and adhesive bonding into a single direct attachment system. The adhesive serves both as the bonding agent and as the means to fill the slot, eliminating the need for separate wooden strip installation and insulation adjustment steps
2Reliability
If the traditional method with wooden strips is used, then the glazed unit is held in place, but the manufacturing process requires multiple components and steps
Solution Approach 1:
The patent extracts and eliminates the peripheral wooden strip component from the glazing assembly. The glazed unit is held in place solely through adhesive bonding directly to the door blade, reducing the number of components from multiple (wooden strip, insulation, adhesive) to just the adhesive itself
Solution Approach 2:
The adhesive serves multiple functions simultaneously: it bonds the glazed unit to the door blade, fills the slot to prevent movement, and provides sealing. This multi-functional approach replaces the traditional wooden strip that served as both structural support and seal
3Strength
If the slot is wholly filled with adhesive, then the contact surface and joint strength increase, but the adhesive quantity and cost increase
Solution Approach 1:
The patent applies adhesive to wholly fill the slot between the glazed unit and door blade, using slightly more adhesive than the minimum required to create a thin film. This excessive action ensures complete filling of the slot, maximizes the contact surface area, and guarantees optimal joint strength while the adhesive cures to form a robust bond
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method results in a faster, cheaper, and more secure glazing process that maintains high resistance to breaking and insulation properties, making it suitable for security doors.
Implementation Method 1
filling the slot at least partly with an adhesive, thus forming a joint between the periphery of the glazed unit and at least a portion of the internal edge of the door blade

AI summary
The invention concerns a method for glazing a door blade (2). The method comprises: - creating an opening (50) in the door blade (2), the opening (50) being delimited by an internal edge (3) of the door blade (2), - placing a glazed unit (10) in the opening such that a slot (51) is formed between a periphery (11) of the glazed unit (10) and the internal edge (3) of the door blade (2), - filling the slot (51) at least partly with an adhesive, thus forming a joint (20) between the periphery (11) of the glazed unit (10) and at least a portion of the internal edge (3) of the door blade (2), and - allowing the adhesive to cure. The invention further concerns a door (1) comprising a door blade (2) and a glazed unit (10) fitted to the door blade (2) according to said method.
