Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrophoresis or electro-osmosis processes are implemented with electrodes, then capillary rise can be stopped, but the device requires continuous electricity and periodic maintenance
Solution Approach 1:
The electromagnetic device operates passively using the Earth's natural electromagnetic field, eliminating the need for external power sources. The device self-regulates by detecting and counteracting the capillary rise phenomenon through its resonant circuits, requiring no human intervention or energy input once installed.
Solution Approach 2:
The patent replaces the active electro-osmosis system with electrodes and power sources with a passive electromagnetic resonant system. Instead of using electrical fields generated by powered electrodes, the device uses naturally occurring Earth electromagnetic fields interacted with through resonant LC circuits to achieve the same capillary rise prevention effect.
2Reliability
If resin or gel based on active chemical compounds is injected into damp walls, then capillary rise is stopped, but the process is laborious, destructive, and uses harmful products
Solution Approach 1:
The patent replaces the mechanical injection process of chemical resins or gels with a passive electromagnetic field-based system. Instead of physically penetrating and injecting substances into wall structures, the device uses electromagnetic resonance to interact with and neutralize the capillary rise phenomenon at a distance, eliminating the need for drilling, injection equipment, and chemical materials.
Solution Approach 2:
The electromagnetic device acts as an intermediary between the Earth's electromagnetic field and the damp wall structure. Rather than directly injecting chemicals into the wall, the device uses electromagnetic fields as a mediator to transmit energy and achieve capillary rise prevention without physical contact or destruction of the wall structure.
3Use of energy by moving object
If complex windings and electronic components are used in passive electromagnetic devices, then power supply is not required, but operating failures can occur
Solution Approach 1:
The patent uses simple, localized conductive elements arranged in specific geometric patterns rather than complex windings. Each conductive element is a simple loop or trace on the film, minimizing the number of components and potential failure points while maintaining the necessary electromagnetic functionality through their geometric arrangement and resonance properties.
Solution Approach 2:
The device uses a composite structure combining conductive material traces on an electrically insulating flexible film. This composite design integrates the electromagnetic functionality directly into a single flexible component, eliminating the need for separate complex windings, capacitors, and electronic components that could fail, while maintaining the passive resonant operation.
4Area of stationary object
If treatment devices are installed to cover large areas, then more walls can be treated, but the device size and complexity increase
Solution Approach 1:
The patent employs multiple independent flexible treatment films that can be individually installed on different wall sections. Each film is a simple, self-contained unit that can be easily positioned and activated independently, allowing coverage of large areas through modular installation rather than using a single large complex device.
Solution Approach 2:
The patent transitions from three-dimensional complex electromagnetic structures to two-dimensional flexible films with printed or traced conductive patterns. This dimensional reduction simplifies the device construction dramatically while maintaining treatment effectiveness, as the electromagnetic resonance can be achieved through planar conductive geometries on flexible substrates.
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
Effectively and sustainably treats rising damp in walls by canceling the potential difference driving water migration, leading to complete drying of walls within 6 to 18 months, with no maintenance or electricity requirements, and covering a significant area.
Implementation Method 1
A passive electromagnetic device with concentric electrical circuits embedded in an insulating medium, capable of phase-shifting the earth's electromagnetic field to neutralize capillary rise
Implementation Method 2
The device includes four parallel oscillating circuits associated with two radiating dipoles which create a counter-field electrically out of phase with the initial electromagnetic field which generates the capillary rises
Implementation Method 3
rising water from the ground. In the latter case, these are the foundation walls of a house which does not have a watertight capillary break level and which are often subject to the geology of the soil or which are built on damp land or close to 'a water table. The humidity then penetrates into the foundation walls, then into those of the building by capillary effect.

AI summary
The device has a plate (22) arranged in a case that is made of a material permeable to electromagnetic field, where the plate has an electric circuit assembly (25) comprising three coplanar electric circuits. Each circuit is made of electric wired conductor, where each conductor is enrolled for forming continuous plane loops (b1-b14). The loops are in the form of a ring, where the loops are arranged in a concentric manner with respect to each other. Slots (f1-f9) of the loops are diametrically opposite, and the circuits are embedded in an insulated electric medium. An independent claim is also included for a method for treating ascent humidity in wall of a building.
