Balcony End Profile Assembly with Attachment Strip for Thick Slabs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing end profiles for balconies and terraces are inadequate for thicker slabs and screed layers, as they create unsatisfactory transitions and drainage issues when used with natural or artificial stone slabs, leading to water accumulation and potential damage.
Innovation Solution
An elongated strip-shaped attachment profile is designed to be mounted on the cover leg of the end profile, allowing it to be used for thicker pavements and screed layers, with features like projections and clamping mechanisms to secure the attachment and ensure proper drainage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cover section is designed to cover only layers below the anchoring leg, then the through-drying of underlying layers is maintained, but a gap opens between the anchoring leg and the tile front side creating drainage problems
Solution Approach 1:
The end profile is divided into functionally distinct segments: the cover section that maintains air supply to underlying layers, the anchoring leg that secures the profile, and the edging section with cover limb that addresses the tile joint. This segmentation allows each part to optimize its specific function without compromising the others.
Solution Approach 2:
The edging section with its cover limb acts as an intermediary element between the anchoring leg and the tile front side. It creates a transition zone that maintains the protective function while enabling proper water drainage through the drainage opening, preventing direct contact between water and the anchoring leg joint.
2Adaptability or versatility
If the cover leg height corresponds to tile thickness for thin-bed laying, then tile coverage is achieved, but the profile cannot be used for thicker slabs and screed layers
Solution Approach 1:
The end profile is designed with universal applicability through the attachment profile that can be mounted on the cover leg. This allows the same base profile to serve multiple functions: thin-bed tile laying, thick slab coverage, and screed layer protection, eliminating the need for different profile designs for different applications.
Solution Approach 2:
The solution adds a vertical dimension to the profile system through the attachable cover leg, which can be adjusted or extended to accommodate different slab and screed thicknesses. This dimensional adjustment allows the profile to adapt to various application scenarios without changing the fundamental structure.
3Reliability
If sealant is used to seal the joint between anchoring leg and tile, then the joint is sealed, but seepage water cannot drain off accumulating and causing efflorescence and frost damage
Solution Approach 1:
The drainage opening in the edging section converts the potentially harmful accumulation of seepage water into a beneficial drainage function. Instead of preventing water entry with sealant, the design allows controlled water entry and directs it through the drainage opening, transforming the water problem into a manageable flow control feature.
Solution Approach 2:
The edging section with cover limb serves as an intermediary that separates the sealing function from the drainage function. It allows the joint to be sealed while providing a dedicated drainage path through the drainage opening, preventing direct conflict between sealing and drainage requirements.
4Object-affected harmful factors
If water-permeable mortar is used to fill the joint, then water can escape, but the mortar undermines the joint over time causing panels to come loose
Solution Approach 1:
The edging section with cover limb acts as a structural intermediary that provides mechanical support and protection to the joint area. It shields the water-permeable mortar from direct water exposure and mechanical stress, preventing the mortar from undermining the joint while still allowing water drainage through the drainage opening.
Solution Approach 2:
The drainage opening converts the potential harm of water penetration into a beneficial drainage function. Instead of preventing water entry, the design allows controlled water flow through the opening, preventing water accumulation that would otherwise cause mortar degradation and joint failure.

AI summary
The arrangement has an enclosure section arranged at a covering section and including a covering limb to enclose free front surfaces of plates laid at an edge area of balcony or terrace. A drainage opening is provided at the enclosure section to drain leakage water accumulated between an end profile and the plates. An elongated, laminar, strip-shaped landing profile (50) includes upper and lower attachment units (52, 60) for attachment at the limb, such that a strip-shaped partial section of the landing profile proceeds over an upper free edge of the limb in the upward direction.
