Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air ionization devices in closed rooms are ineffective in evenly distributing negative ions, leading to premature exhaustion and decreased concentration among occupants due to localized ion generation and potential ozone level exceedance.
Innovation Solution
A configuration of elongated, non-insulated conductors arranged parallel to each other within the room, connected to a voltage source between 5 kV and 10 kV, with a controlled maximum current to ensure even distribution of negative ions across the space without exceeding ozone limits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If air ionization devices are used to generate negative ions at specific points, then negative ion concentration is increased locally, but the distribution of negative ions becomes uneven throughout the room
Solution Approach 1:
The patent divides the room into multiple zones by placing several conductor pairs at different locations (ceiling, walls, floors) rather than using a single ionization device. Each conductor pair serves as an independent ionization unit, collectively achieving uniform distribution throughout the entire space.
Solution Approach 2:
Different conductor pairs are positioned at specific locations (ceiling-mounted, wall-mounted, floor-mounted) to create localized ionization zones that collectively cover the entire room. Each location receives optimized ion concentration according to its specific spatial characteristics.
2Quantity of substance
If high voltage is applied to generate sufficient negative ions, then negative ion concentration increases, but ozone levels may exceed safety limits
Solution Approach 1:
The patent optimizes the voltage parameters applied to each conductor pair (5-15 kV range) to achieve effective ionization while controlling ozone generation. By distributing the ionization load across multiple conductor pairs rather than using one high-power device, the system maintains effective negative ion concentration while keeping ozone levels within safety limits.
3Quantity of substance
If conductor pairs are placed close together to increase ion generation, then negative ion concentration improves, but the risk of electrical discharge and safety hazards increases
Solution Approach 1:
By dividing the ionization function across multiple conductor pairs with larger spacing between them, the patent reduces the electrical field intensity at any single location while maintaining overall ion generation effectiveness. This segmentation approach lowers the risk of electrical discharge and improves safety.
4Device complexity
If a single air ionization device is used, then device complexity is reduced, but the ability to distribute negative ions evenly throughout the room decreases
Solution Approach 1:
The patent employs multiple conductor pairs distributed throughout the room (on ceiling, walls, and floors) to achieve uniform negative ion distribution. Each conductor pair is a simple device, but their coordinated arrangement creates the desired uniform distribution effect that a single device cannot achieve.
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
This approach achieves a uniform concentration of negative ions throughout the room, enhancing occupant well-being and concentration while preventing ozone level exceedance and ensuring safety.
Implementation Method 1
A voltage source with an output voltage between 5 kV and 10 kV is connected to the first and second conductors
Implementation Method 2
In the electric field, gas ionization occurs at the value of the field at which the gas atom or gas molecule reaches an energy on the so-called free path length that is greater than the ionization energy of the particles originating from the gas itself
Implementation Method 3
The voltage that produces such a field strength - also called the threshold voltage - depends mainly on the shape and placement of the electrodes relative to each other

AI summary
The invention relates to an arrangement for increasing the concentration of negative ions in the breathing air of a closed space. In order to make possible a more uniform distribution of the negative ion concentration inside the space without exceeding the permissible limits for ozone in the breathing air, the invention proposes that - at least one conductor pair is arranged in the closed space, - the conductor pair has a first non-insulated conductor, which is switched as the anode, and a second non-insulated conductor, which is switched as the cathode, with the first and second conductors being arranged mutually parallel at a distance, - a voltage source with an output voltage of between 5 kV - 10 kV is connected to the first and second conductors and - the distance between the first and the second conductor is between 10 - 30 mm.
