Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulated slab-on-grade foundation systems lack adaptability to varying foundation dimensions and are inefficient in installation, requiring costly and time-consuming processes.
Innovation Solution
The system employs modular, pre-shaped EPS components with a dovetail locking mechanism for easy assembly and frost protection, allowing for adaptable installation on different-sized projects, using EPS for insulation and a metal U-shaped plate for secure connection, and a vapor barrier for enhanced protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional fixed isolation systems are used for foundation protection, then the system structure is simple, but the system cannot adapt to different foundation dimensions and project sizes
Solution Approach 1:
The isolation system is divided into multiple modular components including side isolation portions, end isolation portions, and base portions that can be assembled in different configurations. Each module can be independently manufactured and then combined to fit various foundation dimensions, allowing the system to adapt to different project sizes while maintaining a relatively simple individual component design.
Solution Approach 2:
The modular isolation modules are designed with universal features that allow them to serve multiple functions and be used in various configurations. The same basic module design can be applied to different foundation types and sizes by simply changing the arrangement and number of modules, rather than designing custom systems for each application.
2Manufacturing precision
If custom-molded insulation systems are used to fit specific foundation sizes, then the system provides precise fit, but the manufacturing cost and time increase significantly
Solution Approach 1:
Rather than manufacturing one custom-molded piece for each specific foundation size, the system segments the insulation into standardized modules that can be manufactured using fixed molds. These modules are then assembled to achieve the required fit, eliminating the need for costly and time-consuming custom molding for each project while maintaining adequate precision through the modular assembly approach.
Solution Approach 2:
The system achieves adaptability to different foundation dimensions by changing the number, arrangement, and configuration of standardized modules rather than changing the fundamental module design. This allows precise fitting to various sizes while using the same manufacturing processes and molds for all modules.
3Stability of the object's composition
If large single-piece insulation components are used, then the system provides continuous insulation coverage, but the installation process becomes difficult and time-consuming
Solution Approach 1:
The insulation system is segmented into smaller, more manageable modules that are easier to transport, position, and install. These modules can be handled by standard equipment and personnel, reducing installation difficulty and time compared to large single-piece components.
Solution Approach 2:
Multiple smaller insulation modules are combined through interlocking mechanisms and overlapping arrangements to create continuous insulation coverage. The modules are designed with features that ensure tight joints and seamless coverage when assembled, achieving the same continuous protection as large single-piece components but with the installation advantages of modular units.
4Adaptability or versatility
If non-modular insulation systems are used, then the system design is straightforward, but the system cannot be efficiently adapted to different construction projects
Solution Approach 1:
The system is divided into standardized modular components that can be independently designed, manufactured, and assembled. This segmentation enables flexibility in configuring the system for different construction projects while keeping individual module designs relatively simple and standardized.
Solution Approach 2:
The modular components are designed with universal features and standardized connection mechanisms that allow them to be used in various configurations and applications. This universality provides adaptability to different construction projects without requiring complex custom designs for each application.

Function Achieved in This Case
This solution enables efficient, cost-effective, and adaptable installation of insulated slab-on-grade foundation systems, reducing installation time and costs while providing effective frost protection and adaptability to various construction projects.
Implementation Method 1
The typical isolation system for foundation does not adjust and is fixed or does not adapt to the different dimension of shallow foundations
Implementation Method 2
the isolated frost protection stays in place after the pouring of the concrete because of the locking mechanism provided by the dovetail
