Solution Overview
Problem
Existing methods for connecting door or window components in miter seams are complex, costly, and require specialized machinery, making them inefficient and expensive, especially when considering materials like steel, plastic, or wood.
Innovation Solution
A connecting device comprising an angular pressure piece with lateral legs and a back pressure piece, which are inserted into hollow chambers of light metal profiles, allowing for a secure, waterproof connection without adhesives and without the need for additional machinery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing methods for connecting door or window components in miter seams are used, then connection stability is achieved, but the process becomes complex and requires specialized machinery
Solution Approach 1:
The connecting device is divided into separate insert and cover parts that can be independently manufactured and assembled. The insert is placed in the hollow chamber of one component, and the cover is placed on the other component, simplifying the overall connection process while maintaining stability.
Solution Approach 2:
The connecting device acts as an intermediary element between two door or window components. It includes an insert with engagement protrusions that fit into corresponding recesses in the cover, creating a stable connection without requiring complex specialized machinery.
2Reliability
If existing connecting devices are used, then secure connection is achieved, but manufacturing cost increases
Solution Approach 1:
By segmenting the connecting device into separate insert and cover parts, each can be manufactured using standard production methods without requiring expensive specialized machinery. This reduces manufacturing costs while maintaining connection security through the engagement protrusion-recess mechanism.
Solution Approach 2:
The connecting device uses simple geometric forms (protrusions and recesses) that can be easily manufactured at low cost. The design avoids complex features, making it suitable for mass production with standard equipment, thereby reducing overall manufacturing expenses.
3Reliability
If miter joints are created with hollow chambers, then connection is possible, but production time increases
Solution Approach 1:
The insert is pre-placed in the hollow chamber of one component before assembly. This preliminary action allows the connection to be quickly completed by simply placing the cover on the other component and engaging the protrusions, thereby increasing production speed while maintaining connection feasibility.
Solution Approach 2:
The engagement protrusions on the insert automatically align with and engage into the recesses in the cover during assembly. This self-aligning mechanism eliminates the need for precise manual positioning or complex alignment procedures, thereby speeding up production while ensuring reliable connection.
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
The solution enables easy, quick, and cost-effective angular connections of light metal profiles, eliminating the need for adhesives and specialized machinery, while ensuring stability and ease of disassembly.
Implementation Method 1
at least one pressure screw (4) which can be actuated from the interior via an opening (10) in the miter area and which serves to simultaneously clamp the light metal profiles (11, 12) to one another in the miter area (13)
Implementation Method 2
The hollow chambers and the design of the connecting devices are dimensionally matched so that there is only minimal play between the inner walls of the hollow chamber and the immersed legs of the connecting devices
