Compact Electric Air Dryer for Bladder and Food Storage Bags
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drying solutions for portable bladders and food storage bags are either too large and non-portable or inefficient in promoting air circulation, leading to mold and mildew growth due to residual water, necessitating a compact and efficient drying method that prevents bacterial growth without harsh chemicals.
Innovation Solution
An electric dryer with a compact design featuring an electric fan and a specially designed insert with a nozzle that directs air into the bladder or bag, promoting air circulation and preventing folding, coupled with a kit for connecting to a bladder's drinking hose for efficient drying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a forced air dryer with larger dimensions is used to effectively dry the bladder, then drying efficiency is improved, but portability deteriorates as it cannot be stored in the same backpack
Solution Approach 1:
The dryer is designed to nest within the bladder itself during storage and transport. The collapsible housing allows the dryer to be compressed to a fraction of its operational size, enabling it to fit inside the same backpack as the bladder it serves.
Solution Approach 2:
The dryer employs a collapsible housing that transitions between a compact storage state and an expanded operational state. This dynamic structure allows the dryer to adapt its volume based on whether it is being stored or used, resolving the contradiction between portability and drying efficiency.
2Volume of moving object
If simple drip drying frames are used, then portability is improved, but drying efficiency deteriorates due to lack of air circulation
Solution Approach 1:
The dryer incorporates an electric fan that generates forced air circulation within the bladder. This pneumatic system actively moves air through the water reservoir, significantly accelerating the evaporation and drying process compared to passive drip drying, while the device remains compact and portable.
3Device complexity
If residual water remains in the bladder, then device complexity is reduced, but harmful factors increase due to mold and mildew growth
Solution Approach 1:
The dryer enables the bladder to dry itself through forced air circulation without requiring external intervention or complex additional systems. The simple design of positioning the dryer within the bladder and activating the fan allows the bladder's own structure to facilitate complete drying, preventing mold and mildew growth while maintaining low device complexity.
4Volume of moving object
If the dryer is made compact for portability, then ease of operation is improved, but power consumption may increase
Solution Approach 1:
The dryer is designed to operate continuously at low power consumption, utilizing the compact electric fan to maintain constant air circulation throughout the drying process. This continuous low-power operation is more energy-efficient than intermittent high-power operation, and the extended runtime compensates for the lower power level, enabling complete drying while maintaining portability.
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 electric dryer effectively dries bladders and food storage bags quickly and efficiently, extending their lifespan by preventing mold and mildew growth, while being portable and low in power consumption, suitable for camping or backpacking trips.
Implementation Method 1
An electric fan and a nozzle to connect to an output of the fan for insertion in a filling portal or opening of a bladder or food storage bag

AI summary
An electric dryer designed for drying a bladder or food storage bag, featuring an electric fan enclosed within a housing, and an insert with a nozzle for directing air into the internal volume of the bag. The insert is dimensioned to be inserted into the bag's opening, separating the front and back panels and preventing the bag from folding along its longitudinal axis. The fan is capable of moving between five and fifteen cubic feet of air per minute. The insert may include a projection to prevent the bag from being blown off and is shaped to project at least an inch into the bag. The dryer may also include a base with at least one projection extending at an angle to the axis of the insert. The power line can be configured to couple to a wall outlet or a battery. The dryer may also come as part of a kit, including a tubular member and a flexible elongated tether for connecting the tubular member to the electric dryer.
