Adjustable Base Profile for Floor Joints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor profile assemblies struggle to securely attach a cover profile to a base profile for joints, as the fastening legs are too short for thick floor coverings, while being inadequate for thin coverings, and cannot be lengthened without compromising fit on thinner surfaces.
Innovation Solution
A base profile with a support leg featuring a flexible part that can be bent vertically to adjust the position of the holding device, allowing for an infinitely adjustable receiving height and accommodating various floor covering thicknesses, along with recesses to extend fastening legs for thick coverings and prevent movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the fastening legs are lengthened to accommodate thick floor coverings, then the cover profile can be securely attached to thick floor coverings, but the fastening legs will come to rest on the base profile with thin floor coverings while the cover profile still protrudes over the floor covering
Solution Approach 1:
The support leg incorporates a flexible part that can be bent to different positions, transforming a static structure into a dynamic, adjustable one. This allows the support leg to adapt its height to match different floor covering thicknesses, enabling the same base profile to work with both thin and thick floor coverings without requiring different fastening leg lengths
Solution Approach 2:
The flexible part of the support leg allows changing the vertical position parameter of the holding device by bending the support leg to different degrees. This parameter change enables adjustment of the receiving height to accommodate varying floor covering thicknesses while maintaining proper positioning of the cover profile
2Manufacturing precision
If the fastening legs are kept short for thin floor coverings, then the cover profile can be properly positioned on thin floor coverings, but the fastening legs are too short to ensure proper attachment for thick floor coverings
Solution Approach 1:
The flexible part of the support leg enables dynamic adjustment of the holding device height. For thin floor coverings, the support leg remains in its original position with short effective fastening legs for precise positioning. For thick floor coverings, the support leg is bent to elevate the holding device, effectively lengthening the fastening path without actually changing the fastening leg dimensions
Solution Approach 2:
By bending the flexible part of the support leg, the vertical position parameter of the holding device is changed. This allows the same physical fastening legs to effectively reach the required depth for both thin and thick floor coverings, achieving adaptability without compromising positioning precision
3Adaptability or versatility
If a separate adjustable holding device is used to accommodate different floor covering thicknesses, then the receiving height can be adjusted, but the number of parts and assembly effort increases
Solution Approach 1:
The flexible part is integrated directly into the support leg as a unified component rather than being a separate adjustable holding device. This merging of functions reduces the number of parts while maintaining the ability to adjust the receiving height by bending the flexible part, thereby reducing assembly effort
Solution Approach 2:
The flexible part acts as a bendable element within the support leg structure, allowing height adjustment through deformation rather than through separate movable components. This approach maintains adaptability while minimizing structural complexity and number of parts
