Telescopic Underfloor Side Wall Structure for Variable Screed Heights
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing underfloor installation components with rigid side walls, such as those made of sheet metal, face challenges in accommodating varying screed thicknesses without additional height adjustments, leading to potential denting and incomplete screed penetration, and existing adjustable solutions compromise installation cavity volume or stability.
Innovation Solution
The underfloor installation component features telescopically adjustable side wall sections connected by guide hooks, allowing for automatic height adjustment of the side wall relative to the base plate, ensuring stability and flexibility across different screed thicknesses without compromising the installation cavity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid side panels made of sheet metal are used, then lateral strength and resistance to screed pressure are improved, but adaptability to varying screed thicknesses deteriorates
Solution Approach 1:
The side wall is divided into multiple side wall parts that can be adjusted independently. Each side wall part can be positioned at different heights to accommodate varying screed thicknesses while maintaining rigid lateral strength through the sheet metal construction of individual segments.
Solution Approach 2:
The side wall structure transitions from a fixed rigid panel to a dynamic adjustable system. The side wall parts can be moved vertically along the base plate to adapt to different screed thicknesses, providing both rigidity when positioned and adaptability through movement capability.
2Adaptability or versatility
If side panels with maximum height are used, then adaptability to varying screed thicknesses is improved, but device complexity and need for on-site adjustment increases
Solution Approach 1:
Instead of using a single maximum-height panel that requires cutting or complex adjustment mechanisms, the side wall is segmented into multiple standardized parts that can be combined in different configurations. This reduces on-site adjustment complexity while maintaining adaptability to various screed thicknesses.
3Adaptability or versatility
If foam formwork frame is used, then adaptability to lower side wall heights is improved, but installation cavity volume is reduced
Solution Approach 1:
The side wall uses thin, adjustable metal segments rather than a bulky foam formwork frame. This segmentation allows the side wall to achieve lower heights without requiring excessive material width, thereby preserving maximum installation cavity volume while maintaining adaptability to different screed thicknesses.
4Ease of operation
If flexible side skirts are used, then ease of installation is improved, but resistance to screed pressure and prevention of denting deteriorates
Solution Approach 1:
The side wall uses rigid segmented panels instead of a single flexible skirt. Each segment can be independently positioned and secured, providing both ease of installation through modular assembly and superior resistance to screed pressure through the rigid sheet metal construction of each segment.
