Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors for frame profiles in window and door construction require spreading aids, especially for small window sizes, making the installation process complex and costly, and do not facilitate easy integration of post, transom, or rung profiles without mechanical assistance.
Innovation Solution
A connector with a penetrating element featuring a transfer element and rotatably mounted contact elements that allows for easy alignment and insertion of post, transom, or rung profiles without the need for spreading aids, utilizing a design with an inclined plane and clamping elements for stability, and made from materials like aluminum-zinc die-cast alloy for durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional connectors are used for frame profiles, then mechanical connection is achieved, but spreading aids are required especially for small windows making installation complex and time-consuming
Solution Approach 1:
The connector acts as an intermediary element between the frame profile and the mullion/transom/glazing bar profile. It includes a connecting plate with frame holes for attachment to the frame profile, and an insertion element that penetrates the hollow chamber of the profile to be connected. This intermediary structure enables direct mechanical connection without requiring spreading aids or complex installation tools.
Solution Approach 2:
The insertion element is designed to be inserted into the hollow chamber of the mullion, transom, or glazing bar profile, effectively nesting the connector within the profile structure. The bearing element is rotatably mounted within the connector assembly, allowing it to adapt to the profile wall during insertion and connection, simplifying the installation process.
2Productivity
If frame profiles are forced apart for insertion, then connection is achieved, but this is particularly time-consuming for small windows and necessitates spreading aids
Solution Approach 1:
The connector is pre-assembled with the insertion element positioned to penetrate the hollow chamber of the profile. The bearing element is pre-mounted on rotation axes that will engage with the profile wall during insertion. This preliminary preparation eliminates the need for on-site spreading operations and reduces installation time significantly.
3Ease of operation
If rotatably mounted bearing elements are added to the connector, then transfer of profile over insertion element is facilitated, but connector complexity increases
Solution Approach 1:
The bearing element is mounted to rotate about an axis, transforming it from a static component to a dynamic one. During the connection process, the bearing element rotates to follow the contour of the profile wall, facilitating smooth transfer of the profile over the insertion element. This dynamic adaptation simplifies operation despite the added rotational mechanism.
