Temperature-Activated Scent Dispenser with Float Valve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scent dispensers for animal attractants are inefficient as they provide continuous scent release, which is wasteful and not time-specific, and can be affected by temperature changes and rain, leading to unwanted human odor contamination and valve blockages.
Innovation Solution
A temperature regulated, pressure activated scent dispenser that releases a portion of liquid scent when a threshold pressure is reached due to ambient temperature changes, ensuring controlled and time-specific scent distribution without continuous manual operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a continuous flow valve is used to dispense scent, then the scent is released continuously, but the scent is wasted and human odor contamination increases
Solution Approach 1:
The patent implements periodic action by using a float valve mechanism that opens and closes based on liquid level fluctuations caused by temperature-induced expansion and contraction of the liquid scent. The valve opens when the liquid level rises (during daytime heating) and closes when the level drops (during nighttime cooling), creating periodic dispensing cycles that match natural temperature patterns without continuous manual operation.
Solution Approach 2:
The system employs self-service through automatic temperature-regulated operation. The float valve mechanism automatically responds to temperature changes by rising and falling with liquid expansion and contraction, opening and closing the dispensing channel without human intervention. This eliminates the need for manual valve operation while preventing both over-dispensing and blockages.
2Ease of operation
If manual valve operation is used to control scent release, then scent can be released at specific times, but continuous manual operation is tedious and increases human odor contamination
Solution Approach 1:
The float valve system provides self-service by automatically controlling scent dispensing based on liquid level changes. The mechanism requires no manual operation - the float rises and falls with temperature-induced liquid expansion and contraction, automatically opening and closing the valve. This eliminates both the tedium of continuous manual operation and the time loss associated with frequent adjustments.
Solution Approach 2:
The patent replaces manual mechanical valve operation with an automatic mechanical system driven by thermal expansion and contraction. Instead of human hands operating a valve, the system uses the physical properties of the liquid scent itself (expansion with heat, contraction with cooling) to drive the float mechanism, which in turn controls the dispensing valve automatically.
3Loss of substance
If low flow rate valve setting is used to conserve scent, then scent waste is reduced, but the valve becomes blocked and flow stops completely
Solution Approach 1:
The periodic opening and closing of the float valve prevents continuous low-flow conditions that lead to blockages. By creating intermittent flow cycles synchronized with temperature changes, the system maintains adequate flow velocity during dispensing periods to prevent debris accumulation, while conserving scent during closed periods when no flow is needed.
Solution Approach 2:
The system dynamically changes the flow parameter from continuous low-flow to periodic variable-flow based on temperature conditions. During daytime heating, the valve opens and allows higher flow rates; during nighttime cooling, the valve closes and stops flow entirely. This parameter change prevents the stagnant low-flow conditions that cause blockages while maintaining scent conservation goals.
4Productivity
If scent is released continuously to maximize animal attraction, then hunting effectiveness increases, but scent is wasted during nighttime and rainy periods
Solution Approach 1:
The float valve mechanism creates periodic dispensing cycles that align with natural temperature patterns - opening during daytime when animals are active and closing during nighttime when activity decreases. This periodic action ensures scent is released when most effective for attracting animals while preventing waste during periods when animal activity is low or scent would be washed away by rain.
Solution Approach 2:
The system changes the dispensing parameter from continuous to conditional based on temperature-driven liquid expansion and contraction. The valve opens when temperature increases cause liquid expansion (daytime conditions favorable for animal activity) and closes when temperature decreases (nighttime conditions less favorable). This parameter change optimizes the balance between animal attraction effectiveness and scent conservation.
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
The dispenser provides efficient, unattended scent release during desired times, reducing waste and minimizing human odor contamination, while maintaining scent effectiveness even during periods of low temperature changes, such as at night or in rain.
Implementation Method 1
As the temperature increases, the volume of the air within the container expands
Implementation Method 2
the volume of the air within the container expands to a point that activates a release structure, thereby releasing a portion of the liquid from the container

AI summary
The present disclosure relates to a temperature regulated, pressure activated liquid scent dispenser. The pressure in the interior of the container may increase as ambient temperature increases. A release structure of the container may release a portion of the liquid scent once a threshold pressure or threshold amount of pressure build-up is reached in the interior of the container. A method comprises filling the interior volume with a liquid scent so that the interior volume also includes a volume of air, suspending the dispenser over a ground surface, and dispensing the liquid scent from the interior volume through the release structure. Due to an increase of pressure of the volume of air, and upon reaching a threshold air pressure, the release structure releases a portion of the liquid scent from the interior volume. Applications may include dispensing animal attractant or repellent.
