Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods for forming building foundations face challenges with slow drying and curing times due to the use of insulating materials like cellular plastic, and prefabricated concrete slabs struggle to provide a leveled foundation.
Innovation Solution
A method involving a slab with an insulating and draining granulate material and a channel system that allows for controlled pressure flow to ventilate and dehydrate the structure, reducing drying and curing times, and using non-organic materials like foam glass for insulation and drainage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a thick layer of cellular plastic insulating material is used to provide necessary insulating properties, then the insulating performance is improved, but the drying and curing time of the concrete ground plate increases significantly
Solution Approach 1:
The insulating layer is segmented into two distinct parts: a lower layer of cellular plastic providing thermal insulation, and an upper layer of granulate material with channel systems for moisture extraction. This segmentation allows each layer to perform its specific function optimally without interfering with the other.
Solution Approach 2:
The granulate material layer acts as an intermediary between the concrete ground plate and the cellular plastic insulation. It provides a permeable medium with channel systems that facilitate moisture removal from the concrete while allowing the cellular plastic to maintain its insulating function underneath.
Solution Approach 3:
A channel system is integrated into the granulate material layer, connected to a vacuum arrangement that creates negative pressure to actively extract moisture from the concrete ground plate. This pneumatic system accelerates the drying process by creating a pressure gradient that draws moisture out of the concrete.
2Loss of time
If a prefabricated concrete ground plate is used to solve drying and curing problems, then the drying time is reduced, but the ability to provide a leveled foundation is compromised
Solution Approach 1:
The system allows for in-situ casting of the concrete ground plate with controlled drying parameters. By using the granulate material and channel system to actively manage moisture removal, the drying conditions can be optimized to achieve both timely drying and proper curing for a leveled foundation.
3Manufacturing precision
If in-situ casting of concrete ground plate is performed on thick cellular plastic insulation, then the foundation can be leveled properly, but the drying and curing process becomes excessively slow
Solution Approach 1:
The insulating system is divided into a lower cellular plastic layer for thermal insulation and an upper granulate material layer with integrated channels for moisture extraction, allowing simultaneous achievement of insulation and accelerated drying.
Solution Approach 2:
The granulate material serves as an intermediary layer between the cast concrete and the cellular plastic insulation, providing a permeable structure with channels that actively removes moisture while permitting the concrete to be cast and leveled in-situ.
Solution Approach 3:
A vacuum arrangement connected to channels in the granulate material creates negative pressure to actively extract moisture from the freshly cast concrete, dramatically reducing drying time while allowing the concrete to cure properly for a leveled foundation.
