Basement Wall Insulation with Vertical Tongue-and-Groove Joints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thermal insulation systems for underground basement structures require laborious and costly separate sealing of seams with sealing compounds, which slows down construction and is inefficient in preventing moisture spread.
Innovation Solution
A wall structure featuring thermal insulation sheets with grooves on both surfaces, attached by a locked tongue-and-groove-joint that forms vertical air channels, eliminating the need for separate sealing compounds and enhancing moisture management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If thermal insulation sheets are sealed with separate sealing compound, then moisture spread is prevented, but construction time and cost increase
Solution Approach 1:
The patent combines the sealing function and drainage function into a single integrated joint structure. The tongue-and-groove joint includes an integrated sealing element that performs both moisture prevention and water drainage functions, eliminating the need for separate sealing compounds and reducing construction steps.
Solution Approach 2:
The joint structure is designed to perform multiple functions simultaneously: mechanical connection, sealing, and drainage. The sealing element within the tongue-and-groove joint serves as both a barrier to moisture and a component of the drainage system, reducing the number of separate components needed.
2Reliability
If separate sealing compound is applied to thermal insulation sheets, then moisture spread is prevented, but construction cost increases
Solution Approach 1:
The sealing function is merged into the structural joint design itself. The tongue-and-groove joint includes an integrated sealing element that eliminates the need for separate sealing compounds, reducing material costs and construction complexity.
Solution Approach 2:
The joint structure is designed to be self-sealing through its geometric configuration. The tongue-and-groove connection automatically creates a sealed joint when assembled, without requiring additional sealing materials or complex installation procedures.
3Stability of the object's composition
If thermal insulation sheets are arranged with tongue-and-groove joints, then structural stability is improved, but moisture management becomes insufficient
Solution Approach 1:
The tongue-and-groove joint is designed to serve dual purposes: providing structural stability through mechanical interlocking and enabling moisture management through integrated drainage channels and sealing elements that work together to control water movement.
Solution Approach 2:
The joint structure incorporates localized features such as drainage channels and sealing elements at specific positions within the tongue-and-groove connection. These local modifications enable the joint to perform both structural and moisture management functions simultaneously.

AI summary
A wall structure which comprises a basic structure forming a basement wall or footing structure being at least partially underground, and a thermal insulation material layer arranged on the outer surface of the basic structure. The thermal insulation material layer comprises adjacently arranged thermal insulation sheets (1, 2) which comprise a first surface and a second surface, and short edge sides and long edge sides (9', 9", 10') delimiting the surfaces, of which the first surface and the second surface comprise grooves, and which thermal insulation sheets are attached into the basic structure by their first surface. The thermal insulation sheets (1, 2) are arranged into the structure so that the long edge sides (9', 9", 10') of the thermal insulation sheets and the grooves on the first surface and on the second surface of the thermal insulation sheets are vertically with respect to the height direction of the basic structure. Furthermore, the long edge sides (9', 10') of the adjacently arranged thermal insulation sheets (1, 2) are attached to each other by a locked tongue-and-groove-joint (7) so that the locked tongue-and-groove-joint comprises inside the locked tongue-and-groove-joint at least one air channel (8', 8") that is in a vertical direction of the wall structure.
