Movable Seal with Universal Trigger Attachment for Sliding Doors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sliding door seals are limited in their actuation methods, as they can only be activated by either pulling or pressing a trigger, and are not easily adaptable for use in both swing and sliding doors, nor can they be modified post-manufacturing to change trigger attachment points.
Innovation Solution
A seal design that allows for the attachment of triggers at two different locations, enabling actuation by either pulling or pressing, with a mechanism involving leaf springs and a rod system that can accommodate multiple trigger configurations, including protrusions beyond the housing, to accommodate various door types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the trigger is fixed at a specific location during manufacturing, then the seal structure is simple and easy to manufacture, but the seal cannot be adapted to different door types or have trigger attachment points changed post-manufacturing
Solution Approach 1:
The seal is designed with a universal trigger attachment system that can accommodate multiple trigger configurations. The housing includes a channel with connection structures that allow the rod to be connected at different positions, enabling the same seal to function with both pull-type and push-type triggers, and to be adapted to different door types without redesigning the entire seal structure.
Solution Approach 2:
The seal structure incorporates dynamic adaptability through the rod connection system. The rod can be connected to the leaf spring at different positions along the channel, allowing the trigger attachment point to be adjusted or changed after manufacturing. This dynamic configuration capability enables the seal to adapt to different application requirements without requiring a completely new design.
2Adaptability or versatility
If the seal is designed for a specific actuation method (pulling or pressing), then the mechanism is simpler, but it cannot be used for both swing doors and sliding doors
Solution Approach 1:
The seal mechanism is designed to be universal across different door types. By providing a rod that can connect to the leaf spring at multiple positions along the channel, the same seal can be configured for pull-type actuation (suitable for sliding doors) or push-type actuation (suitable for swing doors), making it compatible with different door mechanisms while maintaining operational simplicity.
3Productivity
If the trigger attachment point is fixed during manufacturing, then production is faster and more efficient, but subsequent changes or adaptations are not easily possible
Solution Approach 1:
The rod connection system provides dynamic configurability that allows the trigger attachment point to be adjusted after manufacturing. The connection structures in the channel enable the rod to be repositioned or reconnected at different locations, facilitating post-manufacturing adaptations, repairs, or modifications without requiring complex disassembly or specialized tools, thus maintaining ease of repair while enabling productivity during initial manufacturing.

AI summary
The seal has a channel provided in a housing (1) between plate springs (5a, 5b) and an outer side of the housing. The channel extends from an end (52b) of one of the springs (5b) to an end (51a) of the other spring (5a), and over the end of the latter spring to a channel end. A guide is provided at or adjacent to the channel end. A trigger is displaceably arranged in the guide and connected with a bar (8), and actuates a mechanism for displacing sealing strips between positions. A coupling piece (91) of the trigger is provided with a threaded hole running in a longitudinal direction.
