Self-Aligning Sliding Door Seal for Low-Friction Gap Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding door seals face challenges in effectively sealing the top door gap due to the suspension and movement of the door, leading to increased friction, noise, and the need for specific adaptations in different door systems.
Innovation Solution
A sliding door seal with a first and second seal part that run parallel, forming a barrier with a self-aligning element, allowing for flexible adaptation to various door configurations without requiring movable sealing strips, thus providing dynamic sealing and reducing noise and friction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a movable sealing strip is used to seal the top door gap, then sealing effectiveness is improved, but device complexity and friction increase
Solution Approach 1:
The sealing element is designed to be dynamically adaptable through the self-aligning element that can move within the bearing, allowing the seal to automatically adjust to door position variations without requiring complex movable sealing strip mechanisms
Solution Approach 2:
The self-aligning element automatically compensates for positioning errors and adapts to local conditions through its movability in the bearing, eliminating the need for external triggering mechanisms or complex control systems
2Device complexity
If a static seal is used, then device complexity is reduced, but adaptability to local conditions deteriorates
Solution Approach 1:
The seal transitions from a completely static design to a dynamically adaptable one through the self-aligning element that can move within the bearing, enabling automatic adjustment to door position variations while maintaining structural simplicity
Solution Approach 2:
The position of the sealing element can change dynamically through the self-aligning element's movability in the bearing, allowing the seal to adapt to different local conditions without requiring complex structural changes
3Object-affected harmful factors
If friction is reduced by avoiding sliding of sealing parts, then noise is decreased, but sealing effectiveness may deteriorate
Solution Approach 1:
The self-aligning element automatically maintains optimal sealing contact through its movability in the bearing, ensuring sealing effectiveness without requiring sliding friction between sealing parts
Solution Approach 2:
The traditional sliding friction mechanism is replaced by a bearing-based guidance system that allows the sealing element to move smoothly with minimal friction, reducing noise while maintaining sealing effectiveness

AI summary
A sliding door seal for sealing a door gap has a first seal part for fastening to a stationary element (A, E, S) of a sliding door and a second seal part for fastening to a displaceable door wing (F) of the sliding door. The first seal part and the second seal part run parallel to one another and define a longitudinal direction (L). They together form a barrier, in order to close the door gap. The barrier defines a transverse direction (Q). The barrier has at least one self-aligning element which is held movably in a bearing in a guided manner. The sliding door seal according to the invention can be used in a versatile manner and enables friction-free and low-noise actuation of the sliding door seal.
