Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for reducing rising damp in buildings, such as chemical treatments and electro-osmotic devices, either introduce chemical substances or require electrical power, and are not fully effective in eliminating humidity without these limitations.
Innovation Solution
A device that captures and phase-shifts electromagnetic waves resulting from humidity-induced electric charges, using a structure with capturing and reflection elements to cancel out these waves, thereby eliminating the potential difference causing rising damp.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If chemical products or special paints are applied to walls, then rising damp is temporarily reduced, but chemical substances are introduced into the environment
Solution Approach 1:
The patent replaces chemical treatment methods with a physical electromagnetic wave interference system. The device uses capturing elements to detect electromagnetic waves generated by humidity-induced electric charges in the wall, and reflection elements to generate counter-phase waves that cancel the harmful electromagnetic interference, thereby eliminating rising damp without introducing chemical substances into the environment.
Solution Approach 2:
The patent introduces an intermediary electromagnetic wave interference system between the humidity source and the wall structure. The capturing and reflection elements act as intermediaries that detect and neutralize the electromagnetic waves generated by electric charges due to humidity, preventing these waves from causing further moisture accumulation in the wall.
2Object-affected harmful factors
If electro-osmotic devices are used, then rising damp is reduced by acting on potential difference, but electrical power supply is required
Solution Approach 1:
The device operates autonomously by utilizing the electromagnetic waves naturally generated by humidity-induced electric charges in the wall. The capturing elements detect these self-generated waves, and the reflection elements automatically produce counter-phase waves to cancel them, eliminating the need for external electrical power supply while continuously counteracting rising damp.
Solution Approach 2:
The patent converts the harmful electromagnetic waves generated by humidity into a useful signal source. Instead of treating these waves as mere byproducts, the system uses them as the input signal for the interference cancellation process, thereby eliminating the need for external power while effectively counteracting rising damp.
3Object-affected harmful factors
If electro-osmotic devices are placed in contact with walls, then dehumidification is achieved, but the device position is restricted
Solution Approach 1:
The patent transitions from direct wall contact (one-dimensional surface attachment) to electromagnetic wave interaction (three-dimensional spatial operation). The device can be positioned at various distances from the wall and still effectively detect and cancel electromagnetic waves generated by humidity, providing flexibility in installation location and orientation.
