Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional form systems for building structural components, such as foundations, require customization and additional drainage systems, which can be costly and difficult to install, and often compromise the structure, while also failing to address issues like radon and gas mitigation effectively.
Innovation Solution
A system that integrates a form system with a drainage and ventilation system, using a bracket assembly and permeable barriers to retain a flowable building material, providing drainage, ventilation, and thermal insulation, and including a conduit and drainage cores with fabric wrapping to manage air and gas flow, and prevent backfilling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional form systems are used with separate drainage systems, then drainage function is provided, but device complexity and installation difficulty increase
Solution Approach 1:
The patent combines the form system and drainage system into a single integrated unit. The form system includes internal channels and cavities that serve as drainage pathways, eliminating the need for separate drainage components. This merging reduces device complexity while maintaining reliable drainage function through the integrated structure.
Solution Approach 2:
The form system is designed to perform multiple functions simultaneously: it provides structural support during construction, creates the final structural component, and establishes drainage pathways. The integrated design allows the same components to serve both forming and drainage purposes, reducing the number of separate systems needed.
2Reliability
If conventional form systems require additional drainage systems, then drainage is achieved, but installation time and cost increase
Solution Approach 1:
The drainage pathways are pre-integrated into the form system design before construction begins. The channels and cavities are built into the form structure itself, so no separate drainage installation is needed during construction. This preliminary integration eliminates time-consuming separate installation steps.
Solution Approach 2:
By combining form and drainage functions into a single system, the installation process is streamlined. Workers install one integrated system rather than multiple separate systems, reducing installation time and labor costs while ensuring proper drainage functionality.
3Ease of manufacture
If conventional form systems are used, then structural components are formed, but radon and gas mitigation is ineffective
Solution Approach 1:
The form system incorporates porous or permeable materials in strategic locations to allow gas and radon to pass through rather than accumulate. These porous elements create pathways for harmful gases to escape, mitigating their harmful effects while maintaining the structural forming function.
Solution Approach 2:
The form system incorporates specific localized features such as ventilation channels, gas escape pathways, and permeable zones in areas where gas accumulation is most likely. These local quality enhancements address the harmful gas issue without compromising the overall structural forming capability.
4Device complexity
If integrated form and drainage systems are used, then device complexity is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The integrated form system is divided into modular segments or standardized components that can be manufactured with consistent precision requirements. By segmenting the design into repeatable units, the manufacturing precision needed for each component remains manageable while achieving overall system integration.
Solution Approach 2:
The design incorporates standardized dimensions, tolerances, and geometric parameters that optimize manufacturability. By carefully selecting and controlling key parameters such as channel dimensions, wall thicknesses, and connection interfaces, the system achieves precise integration without excessive manufacturing complexity.

AI summary
A system for retaining a flowable and curable building material to form a portion of a foundation includes side walls disposed in a predetermined configuration having a first side wall and a second side wall, and at least one component having an interior cavity disposed in one of the side walls. A bracket assembly includes an outwardly bounding reinforcement post for each of the side walls, a separator bar having a plurality of apertures sized to receive and retain each of the reinforcement posts at locations corresponding to nominal widths of the at least one component. A barrier is disposed between the outwardly bounding posts. The barrier and the component in the side wall is retained in the foundation after the building material cures. The barrier prevents backfill from filling a volume between the outwardly bounding posts.
