Solution Overview
Problem
Existing moisture extraction devices from walls are inadequate in varying conditions, such as temperature gradients, cavity insulation, and ventilation issues, leading to inefficient moisture removal and increased heat loss, particularly in newly built houses with limited ventilation and internal insulation.
Innovation Solution
A device with a partition wall creating different temperature zones within the chamber, allowing deeper penetration into walls without excessive heat loss, and featuring air channels for moisture removal from cavities filled with insulation, along with a customizable design for varying requirements and airflow control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the device penetrates deeper into the wall to remove moisture from the cavity, then moisture removal capacity is improved, but heat loss increases
Solution Approach 1:
The device is divided into multiple functional segments: a front section with air intake openings, a middle section with a partition wall creating separate chambers, and a rear section with air exit openings. This segmentation allows different parts of the device to perform specialized functions - the first chamber handles moisture extraction from the cavity while the second chamber manages airflow and temperature control, enabling deep penetration without excessive heat loss
Solution Approach 2:
The partition wall creates localized temperature zones within the device - the first chamber near the cavity entrance operates at a lower temperature optimized for moisture condensation, while the second chamber maintains a higher temperature to prevent excessive heat loss to the exterior. This local quality differentiation allows the device to penetrate deeper into the wall while maintaining thermal efficiency
2Productivity
If the moisture removing capacity is increased to handle initially moist walls, then drying effectiveness is improved, but heat loss increases
Solution Approach 1:
The device incorporates adjustable airflow control mechanisms that allow the moisture removing capacity to be dynamically adjusted based on the wall's moisture condition. During the initial drying phase, higher airflow rates are used to rapidly remove moisture from the wall and cavity. As the wall dries out, the airflow can be reduced to minimize heat loss, providing adaptive operation that matches the actual moisture removal needs
Solution Approach 2:
The device enables parameter changes in airflow rate and temperature by adjusting the position of the partition wall or using controllable dampers in the air channels. This allows the system to operate at high moisture removal capacity when the wall is initially very moist, then transition to lower capacity operation with reduced heat loss as the drying process progresses and moisture levels decrease
3Adaptability or versatility
If the device is designed to work in varying temperature conditions and wall types, then adaptability is improved, but device complexity increases
Solution Approach 1:
The device is designed with universal features that enable it to function effectively across different wall types (cavity walls, solid walls, insulated walls) and temperature conditions. The adjustable partition wall and controllable airflow system can be configured to match various wall thicknesses, insulation levels, and temperature gradients, making a single device design suitable for diverse building conditions without requiring multiple specialized devices
Solution Approach 2:
The device incorporates adjustable and movable components such as the partition wall that can be repositioned, and dampers that can be adjusted to adapt to different operating conditions. This dynamic adjustability allows the device to maintain optimal performance across varying temperature conditions and wall types without requiring multiple fixed designs, achieving versatility through adaptability rather than through complex multi-version design
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively removes moisture across the width of the wall, reduces heat loss, and improves humidity regulation in both walls and living spaces, enhancing the lifespan of the device and reducing moisture-related issues.
Implementation Method 1
a partition wall which divides the chamber into a first chamber part and a second chamber part, the first chamber part being in open connection with the outside via the openings and the second chamber part being substantially closed, thereby creating different temperature zones inside the device
Implementation Method 2
an air flow channel for a main air flow extends through the inner space between the air intake and the air exit, the main air flow that flows through the air flow channel carries off moisture from the wall
