Solution Overview

Problem

Current body drying apparatuses after a shower or bath are inefficient and uncomfortable, particularly for people with disabilities, as they require users to adopt unnatural postures to dry their feet, leading to increased risk of falling and high energy and resource costs due to the need for multiple towels and frequent washing.

Innovation Solution

A body drier apparatus with a column of average human height, featuring a fan-driven airflow system with strategically positioned diffusion openings and a mouthpiece configuration that optimizes air flow and pressure for uniform drying without requiring users to change posture, ensuring effective drying of the entire body without towels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If air is projected through diffusers in a vertical column to dry the body, then drying effectiveness is improved, but the ability to dry feet effectively deteriorates because users must lift their feet and adopt uncomfortable postures

Engineering Contradiction:
Improvedrying effectivenessVSAvoiduser comfort and safety
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The column is divided into multiple segments (first vertical segment, second upwardly inclined segment, third downwardly inclined segment) with diffusers distributed across different orientations. This segmentation allows air to be projected at various angles to cover different body parts including feet, eliminating the need for users to adopt uncomfortable postures while maintaining drying effectiveness.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention transitions from a purely vertical column configuration to a three-dimensional structure with upwardly and downwardly inclined segments. This dimensional change enables air projection in multiple directions (upward, downward, lateral) from diffusers positioned on different surfaces of the column, allowing effective foot drying without requiring user movement.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If the column is made taller to cover the entire body including feet, then integral drying is improved, but the risk of falling and discomfort increases due to unstable postures

Engineering Contradiction:
Improveintegral drying coverageVSAvoiduser safety
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

Instead of using a single tall vertical column, the invention segments the column into multiple sections with different orientations (vertical, upwardly inclined, downwardly inclined). Each segment contributes to drying specific body parts, achieving integral drying coverage while maintaining a stable, short column structure that does not require users to adopt unstable postures.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different segments of the column have different orientations and diffuser arrangements optimized for specific body parts. The downwardly inclined segment with downwardly directed diffusers specifically addresses foot drying needs, providing localized effective drying without requiring the entire column to be tall and unstable.

Inventive Principle:
Principle #3Local quality

3Productivity

If air pressure is increased to improve drying speed, then drying effectiveness is improved, but energy consumption increases

Engineering Contradiction:
Improvedrying speedVSAvoidfan energy consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The column is segmented into multiple sections with diffusers distributed across different surfaces and orientations. This segmentation allows air to be projected efficiently in multiple directions simultaneously, improving drying speed without requiring excessive air pressure or fan energy consumption, as the air is utilized more effectively across the entire body surface.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The distributed diffusers across multiple column segments ensure continuous and uniform air projection over the entire body surface including feet. This continuous action maximizes the utilization of the driven air, improving drying speed without wasting energy, as air is delivered continuously and effectively to all areas requiring drying.

Inventive Principle:
Principle #20Continuity of useful action

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 apparatus enables efficient and comfortable drying of the entire body, including feet, without the need for towels, reducing energy expenditure and improving accessibility for individuals with disabilities by maintaining optimal air flow and pressure, thus enhancing user safety and hygiene.

Implementation Method 1

a fan (10) for driving air and a column (20) which is about the average height of a person, longitudinally defining a channel on the inside thereof

Methodology Applied
Scientific EffectFluid flow:

Implementation Method 2

a distribution of openings defined with an outwardly protruding edge are open on the front part of the column... flow out through the openings of the front part acting as diffusers for projecting the air to the outside

Methodology Applied
Scientific EffectDiffusion: Diffusion

Implementation Method 3

which prevents head loss of the air in said inflow, taking optimal advantage of the action of the fan driving the air

Methodology Applied
Scientific EffectHead loss reduction:

Implementation Method 4

the inner channel of the column through which air circulates to flow out through the diffusion openings for projecting the air outwards becomes progressively narrower from top to bottom, thereby defining a compensation for the loss of speed in the circulation of the air

Methodology Applied
Scientific EffectFluid flow compensation:

Implementation Method 5

the outwardly protruding edge of the diffusion openings is envisaged, where appropriate, according to a curved taper, with a radius of curvature and a ratio between the end aperture and the base aperture, which favors the outflow of air without any head loss
