Wall Element Sealing Profile Assembly for Tolerance Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sealing solutions for blower sets and air ducts fail to maintain tightness when individual wall elements have higher manufacturing tolerances, often requiring additional stabilization and increased material usage.
Innovation Solution
A sealing profile with inclined sealing lips and a convex end surface is designed to fit between wall elements, allowing for assembly with reduced tolerance requirements, eliminating the need for separate supports and ensuring tightness through a combination of adhesive tape and the profile's design, which adapts to varying dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional sealing solutions with large contact surfaces and deformable sealing lips are used, then tightness is maintained even with tolerance deviations, but the sealing structure becomes larger and requires more material
Solution Approach 1:
The sealing profile changes its geometric parameters dynamically - the inclined sealing lips are designed to deform and increase their contact surface area when subjected to pressure differential, allowing the seal to adapt to tolerance variations without requiring a permanently large sealing structure
Solution Approach 2:
The sealing lips transition from a static configuration to a dynamic one where they deform under pressure differential to enhance sealing contact, enabling the seal to self-adjust and maintain tightness across a range of tolerance conditions
2Stability of the object's composition
If additional support elements are added between wall elements, then stabilization is improved, but device complexity and assembly requirements increase
Solution Approach 1:
The sealing profile is merged with the wall element structure itself, with the sealing lips integrated directly into the plate section rather than being separate components, thereby providing both sealing and structural stabilization functions in a single element
Solution Approach 2:
The sealing profile serves multiple functions simultaneously: it provides sealing against leakage, stabilizes the wall element connection, and compensates for tolerance variations, eliminating the need for separate support elements
3Reliability
If tight sealing requirements are enforced, then manufacturing precision must be high, but production costs increase
Solution Approach 1:
The sealing profile performs self-adjustment through deformation of its sealing lips under pressure differential, automatically compensating for manufacturing tolerances without requiring high-precision manufacturing or additional adjustment mechanisms
Solution Approach 2:
The sealing structure changes its geometric parameters (contact surface area, lip deformation) in response to operating conditions, allowing it to maintain effective sealing across a wide range of manufacturing tolerances
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 achieves effective sealing with reduced manufacturing costs and simplified assembly, maintaining tightness under both overpressure and negative pressure conditions without additional support profiles, while allowing for wider production tolerances and aesthetic appeal.
Implementation Method 1
The profile has an end surface 2 which is placed perpendicular to the part constituting the sealing section 3 itself. The sealing section 3 is build up of a base part 4 from which sealing lips protrude on one side... The lips are designed in a way that they approximately are inclined 45° towards the end surface 2
Implementation Method 2
The fixing means selected is applied on the base part 4 and its plane surface/side 6

AI summary
A device, preferably a sealing profile (1) which is assembled on a first wall element (8) and on a second wall element (9) respective, and where the sealing profile is assembled on the gable (17) of the wall elements, i.e. in the extension of the wall elements and where the width of the sealing profile only corresponds to a part of the width of that plate profile or that gable which is included by the wall elements and where the assembling of the movable wall element (9) in a first step is obtained by simply fit in between the fixed assembled wall elements, in order to, by the final assembling, be pressed in to its final position.
