Oxidant Coil Scent Control with Turbulent Airflow Neutralization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for masking human scent using natural scents are ineffective in preventing animals from detecting humans, as animals can still sense both the human and applied scents, alerting them to the person's presence.
Innovation Solution
A scent control apparatus with a fan, oxidant generator coil, and flow-restricted output vent that induces turbulent airflow to enhance oxidant generation, chemically altering scent molecules and neutralizing them, using a detachable oxidant generator coil for ease of maintenance and adjustable oxidant output based on local conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If natural scents are applied to mask human scent, then the human scent is masked, but animals can still detect both the human scent and the applied natural scent
Solution Approach 1:
The patent applies oxidants (such as ozone) to chemically alter and neutralize scent molecules rather than attempting to mask them with other scents. This converts the harmful detection capability into a beneficial neutralization process, where the oxidant breaks down the scent molecules themselves, making them undetectable to animals.
Solution Approach 2:
The patent changes the chemical parameters of the scent molecules through oxidation. By altering the chemical composition and structure of the scent molecules via oxidant exposure, the system transforms the scented molecules into non-detectable forms, fundamentally changing their detectability parameter rather than attempting to mask them.
2Ease of repair
If a detachable oxidant generator coil is used, then ease of maintenance is improved, but device complexity increases
Solution Approach 1:
The oxidant generator coil is designed as a separate, detachable component that can be removed from the main device body for maintenance or replacement. This segmentation allows the coil to be serviced independently without disassembling the entire device, improving maintenance accessibility while adding only minimal structural complexity.
Solution Approach 2:
The oxidant generator coil is extracted as a removable component from the integrated device structure. This extraction enables easy removal and replacement of the coil for maintenance purposes, separating the maintenance function from the operational components and simplifying the overall maintenance process.
3Productivity
If flow-restricted output vent is used to induce turbulent flow, then oxidant generation efficiency is improved, but device complexity increases
Solution Approach 1:
The flow-restricted output vent creates turbulent flow conditions by changing the flow parameters (velocity, pressure distribution) as air passes through the restricted opening. This parameter change enhances the mixing efficiency and oxidant generation effectiveness without requiring complex mechanical components.
Solution Approach 2:
The system uses pneumatic principles to create turbulent flow through the flow-restricted output vent. The restriction in the vent creates pressure differential and flow turbulence that enhances oxidant generation efficiency, utilizing gas dynamics rather than mechanical complexity to achieve the desired effect.

AI summary
A scent control apparatus can include: a housing defining a first aperture and a second aperture; an intake vent and a flow-restricted output vent respectively coinciding at least in part with the first aperture and the second aperture; a fan positioned inside the housing and operable to bring air through the intake vent and flow air directly from the fan and into a chute leading to the flow-restricted output vent; and a cartridge including an oxidant generator coil, the cartridge being removably secured to the housing to position the oxidant generator coil between the fan and the chute.
