Height-Adjustable Stair Nosing Profile Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of laying floor coverings on stair nosings, particularly due to varying staircase thicknesses, requires a high variety of stair nosing profiles, leading to increased storage costs and the need for precise cutting to avoid gaps.
Innovation Solution
A height-adjustable stair nosing profile with a vertical contact leg that can be divided into upper and lower parts, allowing for adjustable positioning and fastening via webs and recesses, ensuring compatibility with different step thicknesses without visible installation marks, and featuring a slide-in channel for easy laying and enhanced slip resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple variants of stair nosing profiles are kept available to accommodate different staircase thicknesses, then the adaptability to different step thicknesses is improved, but the storage costs and device complexity increase
Solution Approach 1:
The stair nosing profile is divided into an upper part and a lower part that can be adjusted relative to each other. The vertical contact leg can be positioned at different heights by inserting webs into corresponding recesses, allowing the same profile to accommodate various staircase thicknesses without requiring multiple variants.
Solution Approach 2:
The profile transitions from a fixed configuration to a dynamically adjustable one. The height of the vertical contact leg can be changed by repositioning the upper part relative to the lower part through the web-recess fastening mechanism, enabling adaptation to different step thicknesses while maintaining a seamless appearance.
2Device complexity
If the stair nosing profile is made height-adjustable to reduce variants, then the storage costs are reduced, but the ease of manufacture decreases due to the complex assembly mechanism
Solution Approach 1:
The profile is segmented into modular components (upper part, lower part, webs, recesses) that can be manufactured separately using standard processes and then assembled. This modular approach simplifies manufacturing of individual parts while achieving the complex adjustable function through their combination.
3Adaptability or versatility
If the vertical contact leg is divided into upper and lower parts for height adjustment, then the adaptability to different thicknesses is improved, but the visual seamless appearance may be compromised by visible division lines
Solution Approach 1:
The web-recess fastening mechanism acts as an intermediary that connects the upper and lower parts while remaining hidden. The webs insert into recesses on the opposite side, creating a secure mechanical connection that is not visible from the front, thus maintaining the seamless appearance while enabling height adjustment.

AI summary
The invention relates to a multi-part stair tread front edge profile (1) with a vertical support leg (2) for covering a stair tread front edge as intended, and with at least two retaining webs (4, 5) which together with the support leg (2) form an insertion channel (6) for receiving a stair tread front edge covering as intended, characterized in that the stair tread front edge profile (1) has an upper part (50) and a lower part (60) separate from the upper part (50), wherein the vertical support leg (2) is formed partly by the upper part (50) and partly by the lower part (60) and each has fastening means by which the upper part (50) and the lower part (60) can be fastened to each other in different height positions relative to each other.
