Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing footwear drying and sanitizing devices do not effectively dry footwear in an inverted position or provide bactericidal, fungicidal sanitization without chemicals, and lack forced air and UV light functionality.
Innovation Solution
A footwear dryer and sanitizer apparatus featuring removable tubes with ultraviolet bulbs, heating elements, and fans that support footwear in an inverted position, using warmed air for drying and sanitizing without chemicals, with a controller regulating temperature and fan power, and a grate to catch debris.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If footwear is dried without forced air, then the device structure is simpler, but drying speed and effectiveness are reduced
Solution Approach 1:
The patent employs a fan-driven forced air circulation system where air is drawn through heating elements and blown through tubes positioned near the footwear. This pneumatic approach accelerates moisture evaporation and removal, directly resolving the contradiction by providing high drying speed through controlled air flow rather than passive evaporation.
2Productivity
If footwear is dried in upright position, then the device structure is simpler, but moisture drainage is less effective
Solution Approach 1:
The patent inverts the footwear during the drying process by positioning the footwear holders with the opening facing downward. This inversion allows gravity to assist moisture drainage from the footwear while the forced air system simultaneously evaporates and removes moisture, effectively combining gravitational drainage with mechanical drying.
3Reliability
If sanitization is accomplished by drying alone, then the device structure is simpler, but bactericidal and fungicidal effectiveness is insufficient
Solution Approach 1:
The patent replaces chemical sanitization methods with a physical approach using ultraviolet (UV) light. UV-C bulbs are positioned within the device to emit germicidal radiation that kills bacteria and fungi on the footwear surfaces. This substitution of mechanical/physical means for chemical methods achieves reliable sanitization without chemical residues.
4Ease of operation
If tubes and components are fixed, then the device structure is more stable, but cleaning and maintenance become difficult
Solution Approach 1:
The patent divides the drying system into separable components including removable tubes, detachable footwear holders, and accessible UV bulbs. This segmentation allows each component to be independently removed, cleaned, and maintained without disassembling the entire device, directly improving cleaning ease while maintaining structural integrity during operation.
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
Efficiently dries and sanitizes footwear in an inverted position using warmed air and UV light, effectively killing microorganisms, while being easy to clean and maintain with replaceable components.
Implementation Method 1
The air is warmed by the heating elements placed proximal to the bottom end of each lower tube
Implementation Method 2
Air cycles through the air intake of the base, through the tubes, and past the footwear holders into the footwear
Implementation Method 3
Each set of tubes is comprised of two tubes which are separable. A grate is disposed proximal to the top of the lower tube... ultraviolet bulbs... effectively killing microorganisms

AI summary
A footwear dryer and sanitizer apparatus comprising a base with upwardly extended, removable, hollow tubes. The top of each tube is removably fitted with a footwear holder, each holder fitted with at least one ultraviolet bulb for sanitation of footwear. The apparatus further comprises a controller for regulating the removable bulbs, heating elements, and fans, such that forced drying air for footwear is warmed. The apparatus supports and holds a pair of footwear for drainage and drying and sanitation, without the need for chemicals or solutions.
