Portable Blower with Integrated Heater and Ring Handle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blower devices lack a portable design with a cylindrical housing and integrated handle for efficient drying of vehicles after washing, as they do not effectively direct air flow and often require manual wiping, which can damage the vehicle's finish.
Innovation Solution
A portable blower device with a cylindrical housing and a ring handle that integrates a blower and heater, allowing air to be directed onto the vehicle through an exhaust port, with adjustable speed settings and a power supply for efficient drying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual wiping is used to dry the vehicle, then the vehicle can be dried, but the vehicle's finish may be damaged
Solution Approach 1:
The patent replaces the mechanical wiping system (cloth or towel contact with vehicle surface) with a pneumatic system (blower directing air flow). The blower assembly uses forced air convection to evaporate and remove water from the vehicle surface without physical contact, thereby maintaining drying efficiency while eliminating the harmful mechanical action that could scratch or damage the vehicle's finish.
2Ease of operation
If a portable blower device with cylindrical housing and integrated handle is designed, then ergonomics and portability are improved, but device complexity increases
Solution Approach 1:
The patent merges multiple functions into a single integrated unit: the cylindrical housing serves as both the structural container and the exhaust port, the handle is formed as a continuous ring around the cylinder for ergonomic gripping, and the blower mechanism is integrated within the housing. This consolidation improves portability and ease of operation while managing device complexity through functional integration rather than separate components.
3Productivity
If heated air is used to enhance drying, then drying speed is improved, but energy consumption increases
Solution Approach 1:
The patent changes the temperature parameter of the air stream by incorporating a heating element within the cylindrical housing. The heater warms the air before it is blown onto the vehicle surface, increasing the drying speed through enhanced evaporation. This parameter change (from ambient temperature air to heated air) directly improves productivity while accepting increased energy consumption as a trade-off for faster drying performance.
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
Facilitates efficient and ergonomic drying of vehicles without manual wiping, enhancing the drying process by directing heated air for faster evaporation and reducing the risk of damage to the vehicle's finish.
Implementation Method 1
The heater is integrated into the cylinder such that the heater is in thermal communication with an interior of the cylinder
Implementation Method 2
The heater is positioned between the blower and the exhaust port to heat the air is blown by the blower
Implementation Method 3
A blower is rotatably integrated into the cylinder to urge air outwardly through the exhaust port

AI summary
A portable blower assembly includes a cylinder that has an exhaust port integrated into the cylinder. A handle extends around the cylinder and the handle can be gripped by a user for directing the exhaust port toward a vehicle. A blower is rotatably integrated into the cylinder to urge air outwardly through the exhaust port thereby facilitating the air to be directed onto the vehicle for drying the vehicle when the blower is turned on. A heater is integrated into the cylinder such that the heater is in thermal communication with an interior of the cylinder. The heater is positioned between the blower and the exhaust port to heat the air is blown by the blower for enhancing drying the vehicle.
