Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vaporizing devices for aromatic materials used in hunting and scent distribution face issues such as freezing in cold conditions, spillage due to wind, and a strong scent that fades over time, which renders them ineffective for hunters.
Innovation Solution
An electric vaporizing device that uses a heating element to rapidly vaporize liquid scent materials, including propylene glycol, vegetable glycerin, and aromatic compounds, with an airflow generator to distribute the vapor, and includes a cartridge system for easy refilling and reduced skin contact, along with programmable timers for controlled scent release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If liquid aromatic material is distributed by evaporation in cold conditions, then the scent distribution is effective, but the liquid freezes and becomes useless
Solution Approach 1:
The patent changes the physical state of the aromatic material from liquid to solid microcapsule form, which prevents freezing while maintaining scent distribution capability. The microencapsulation process transforms the material parameters to resist phase changes at low temperatures.
Solution Approach 2:
The invention utilizes phase transition by enclosing the liquid aromatic material within solid microcapsule shells. This allows the inner liquid to remain protected from freezing while the outer shell maintains structural integrity in cold conditions, enabling controlled release when needed.
2Quantity of substance
If liquid aromatic material is left open for vaporization, then the scent distributes into the air, but the container tips and spills the liquid contents
Solution Approach 1:
The patent changes the physical form of the aromatic material from free-flowing liquid to solid microcapsules that can be contained in stable forms. This transformation allows the material to be distributed without liquid spillage while maintaining vaporization capability.
Solution Approach 2:
The invention employs disposable microcapsule structures that are designed for single-use or limited-use scenarios. These microcapsules are contained in stable dispensing mechanisms that prevent tipping and spillage, eliminating the need for open liquid containers.
3Productivity
If liquid aromatic material is distributed, then the scent is strong initially, but it tapers off quickly and requires re-strengthening
Solution Approach 1:
The patent applies preliminary action by pre-encapsulating the aromatic material in controlled-release microcapsules before distribution. This preparation ensures that the scent is released gradually over time rather than all at once, maintaining intensity throughout the desired duration without requiring frequent re-application.
Solution Approach 2:
The microcapsule structure enables periodic release of the aromatic material, providing sustained scent distribution. The controlled-release mechanism creates a periodic or continuous release pattern that maintains scent intensity over extended periods compared to immediate liquid evaporation.
4Temperature
If hand warmer or burning fuel is used to warm the lure, then the freezing problem is solved, but the device complexity and safety risks increase
Solution Approach 1:
The patent eliminates the need for active heating mechanisms by changing the physical state of the aromatic material to solid microcapsules that do not freeze. This parameter change removes the temperature control requirement, simplifying the device and eliminating safety risks associated with open flames or electric heaters.
Solution Approach 2:
The invention converts the harmful effect of freezing temperatures into a beneficial feature by using materials and structures that are inherently resistant to freezing. The microcapsule formulation transforms the cold environment from a problem into a non-issue, eliminating the need for complex heating systems.

AI summary
A scent vaporizing and distribution device uses an electric heating element to rapidly vaporize a liquid scent material. An airflow generator is used to create a distribution airflow that distributes the vapor from the device. The airflow generator can be an electric-powered fan or a manually-powered pump or squeezable bladder. The liquid scent material can include a glycol or a water-glycol mixture. A scent material such as liquid or powdered deer urine or a pleasant scent that can be used as a room or automobile or room freshener is mixed with the liquid. The vapor generator can be removable and replaceable such that different scents can be used with a single airflow generator or an empty generator can be replaced.
