Solution Overview

Problem

Conventional drying methods, such as towel drying, are inefficient and resource-intensive, leading to inadequate drying, particularly in areas like gyms and hotels, resulting in increased laundry loads and water consumption, which is environmentally detrimental.

Innovation Solution

A forced airflow drying apparatus that uses a body with air inlets, flow guides, and an airflow generator to produce a directed airflow for efficient drying, reducing reliance on towels and minimizing water usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If towel drying is used, then drying of the person can be achieved, but the number of towels required increases and laundry loads increase

Engineering Contradiction:
Improvedrying efficiencyVSAvoidnumber of towels
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

The patent replaces the mechanical action of towel drying with a forced air flow system. An air outlet generates a stream of air that passes over the person's body to evaporate and remove moisture, substituting the need for physical towels and manual drying actions.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The invention uses pneumatic principles by generating a controlled air flow through an air outlet. The forced air stream utilizes gas dynamics to transport moisture away from the person's body, achieving drying through fluid mechanics rather than absorbent materials.

Inventive Principle:
Principle #29Pneumatics and hydraulics

2Ease of operation

If towels are used frequently, then drying can be achieved, but water consumption increases due to laundering

Engineering Contradiction:
Improvedrying capabilityVSAvoidwater consumption
Core Design Contradiction:
Ease of operationVSLoss of substance

Solution Approach 1:

The patent replaces the water-intensive towel laundering process with a mechanical air drying system. The forced air flow evaporates moisture directly from the person's body without requiring water for cleaning or laundering towels, significantly reducing water consumption.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The air drying system enables self-service drying where the person is dried by the generated air stream without requiring separate laundry processes. The system handles the entire drying function independently, eliminating the need for water-based towel maintenance.

Inventive Principle:
Principle #25Self-service

3Productivity

If towel drying is used, then moisture can be removed, but drying time is excessive particularly for hair and feet

Engineering Contradiction:
Improvedrying speedVSAvoiddrying time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent employs continuous forced air flow that periodically replaces the air in contact with the person's body, maintaining a consistent temperature and moisture gradient that accelerates evaporation. This continuous periodic action of air renewal speeds up the drying process compared to static towel drying.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The invention changes the parameters of the drying environment by controlling air temperature, flow rate, and direction through the air outlet. These parameter adjustments create optimal conditions for rapid evaporation, significantly reducing drying time for difficult-to-dry areas like hair and feet.

Inventive Principle:
Principle #35Parameter changes

4Adaptability or versatility

If towels are used in gyms and hotels, then drying service is provided, but laundry loads and energy consumption increase

Engineering Contradiction:
Improvedrying service availabilityVSAvoidlaundry energy consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent replaces the energy-intensive laundry mechanical system with a direct air drying mechanism. By eliminating the need for towel collection, washing, and drying cycles in laundry facilities, the system dramatically reduces energy consumption while maintaining drying service availability in gyms and hotels.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The air drying system provides self-service drying capability that eliminates dependency on centralized laundry operations. Users can dry themselves immediately without contributing to laundry loads, making the system particularly suitable for high-traffic locations like gyms and hotels where towel turnover would be excessive.

Inventive Principle:
Principle #25Self-service

AI summary

A forced airflow drying apparatus includes a body including an air inlet, a flow guide having a first end coupled to the air inlet and a second end opened to an upstream side of a filter unit, and an airflow generator to generate a forced airflow. The airflow generator has a first end and a second end, where the first end of the airflow generator is opened to a downstream side of the filter unit. An air outlet is in communication with the second end of the airflow generator to receive the forced airflow from the airflow generator and to expel the forced airflow out of the body.
