Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door seal devices for pivot doors require a large amount of space and are difficult to adapt to narrow vertical door gaps, as well as being inflexible to local conditions and dimensions.
Innovation Solution
A seal device with a triggering module that includes a rotation element and guide element, allowing the rotation element to act on the actuating part without being connected, minimizing transverse forces and enabling a compact design suitable for narrow door leaves, along with a drilling jig for easy mounting on the door leaf.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing triggering mechanisms with rollers or rotation elements are used, then the seal device can be actuated during door closing, but the space requirements become too large for narrow vertical door gaps
Solution Approach 1:
The triggering mechanism is divided into separate functional components: a rotation element (ball or roller) that contacts the door frame, a coupling part that holds the rotation element, and a guide element that provides guided movement. This segmentation allows each component to be optimized independently and assembled in a compact configuration suitable for narrow door gaps.
Solution Approach 2:
The coupling part is designed to be movable relative to the guide element, with the rotation element held within the coupling part. This nested arrangement allows the components to be compactly arranged within the limited space of narrow vertical door gaps while maintaining full actuation functionality.
2Reliability
If fixed stop surfaces with run-up ramps are used, then the rotation element can be properly actuated, but specially shaped ramps are required which complicate the design and reduce adaptability
Solution Approach 1:
The guide element provides a universal guided movement path that works with standard door frame geometries. The coupling part's guided movement relative to the guide element creates a universal triggering mechanism that does not require specially shaped run-up ramps, making the seal device adaptable to various door dimensions and local conditions while maintaining reliable actuation.
3Force
If the rotation element is directly connected to the actuating part, then force transmission is direct, but transverse forces increase causing excessive wear on the triggering bolt and door frame
Solution Approach 1:
The coupling part acts as an intermediary between the rotation element and the actuating part. As the coupling part moves guidedly relative to the guide element, it mediates the force transmission from the rotation element to the actuating part, minimizing transverse forces and reducing wear on the triggering bolt and door frame while maintaining effective actuation.

AI summary
A seal device for a door with a pivotable door leaf includes a drop-down seal for arrangement on or in the door leaf. The drop-down seal has a housing profile rail, a sealing strip, a lowering mechanism, and an actuating part. The seal device includes a triggering module with a rotation element, wherein the triggering module acts on the actuating part when the door leaf is being closed. The triggering module has a guide element for fastening the triggering module on or in the door leaf or fixedly on the housing profile rail. The rotation element is held in a coupling part and the coupling part can be moved relative to the guide element with guidance by the guide element. The seal device makes it possible to use a triggering module optimally in force terms and can also be used in pivot doors, in particular in rebated doors.
