Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for treating thermal bridges between floors and walls are cumbersome due to the large volume and complexity of thermally insulating bodies, making them difficult to transport and install effectively.
Innovation Solution
A method involving the alternating placement of thermal insulation elements and structural connection elements along the wall, where each element performs a single function, simplifying handling and installation by concentrating reinforcements within structural connection elements, thus allowing for a quick and easy implementation of thermal insulation between the floor and wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If thermally insulating elements with reinforcement bars are used to treat thermal bridges between floor and wall, then thermal insulation performance is improved, but the volume and weight of the elements increase, making them difficult to transport and install
Solution Approach 1:
The patent divides the traditional single integrated thermally insulating element into two separate components: a pure thermal insulation element without reinforcement bars, and a separate structural connection element (concrete block with reinforcement bars). This segmentation allows the insulation element to be smaller and easier to handle, while the structural function is fulfilled by the separate connection element.
Solution Approach 2:
The reinforcement bars are extracted from the thermal insulation element and placed in a separate structural connection element. This extraction removes the harmful factor (large volume and weight) while preserving the useful function (thermal insulation), as the insulation element can now be made from lightweight materials without needing to incorporate heavy reinforcement.
2Strength
If thermally insulating elements with reinforcement bars are used to rigidly connect floor and wall, then structural connection strength is improved, but the complexity of installation increases due to handling large-volume elements
Solution Approach 1:
The system is segmented into two specialized components: a thermal insulation element for insulation purposes and a structural connection element for structural purposes. This allows each element to be optimized for its specific function, with the connection element being smaller and easier to handle than a traditional large insulating element with embedded reinforcement.
Solution Approach 2:
The structural connection element is designed to be self-contained with reinforcement bars already positioned within it, eliminating the need for complex on-site reinforcement placement. The element arrives ready-to-install, reducing installation complexity while maintaining strong structural connection capabilities.
3Stability of the object's composition
If reinforcement bars are distributed throughout thermally insulating elements, then structural integrity is improved, but the handling and manipulation of insulation elements becomes difficult
Solution Approach 1:
The patent separates the structural reinforcement function from the thermal insulation function by creating distinct elements. The thermal insulation element contains no reinforcement bars, making it lightweight and easy to handle, while the structural connection element contains all the reinforcement bars needed for structural integrity.
Solution Approach 2:
Reinforcement bars are extracted from the thermal insulation element and concentrated in the structural connection element. This extraction eliminates the handling difficulties associated with reinforcement-containing insulation elements while preserving structural integrity through the dedicated connection element.

Function Achieved in This Case
This method effectively reduces thermal bridges by creating a rigid connection between the floor and wall while simplifying the handling and installation of insulation elements, enhancing both thermal insulation and structural support.
Implementation Method 1
Each element has reinforcement bars passing through it so that they protrude on both sides... the thermally insulating elements arranged between them minimize the corresponding thermal bridges
