Solution Overview

Problem

Conventional shoe dryers often inadequately dry the toe portion of shoes due to air being blown in the same direction regardless of the shoe's position, leading to insufficient drying or excessive drying when temperature or wind volume is increased.

Innovation Solution

A shoe dryer with a camera that captures images of the shoe to determine the position of the shoe's mouth portion and adjusts the direction of air blown by the blowing unit to target the center of the mouth portion, ensuring efficient drying.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If air is blown in the same direction regardless of the shoe's position, then the blowing unit structure is simple, but the toe portion of the shoe is insufficiently dried

Engineering Contradiction:
Improveblowing unit structureVSAvoiddrying uniformity
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The blowing unit is made rotatable to dynamically adjust its blowing direction based on the detected shoe position, transforming a static structure into a dynamic one that can adapt to different shoe orientations, thereby achieving uniform drying without increasing structural complexity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system uses image recognition to detect shoe position and provides feedback to control the rotation of the blowing unit, creating a closed-loop control system that automatically adjusts the blowing direction to match the shoe's actual position, ensuring precise and uniform drying

Inventive Principle:
Principle #23Feedback

2Productivity

If the temperature of air blowing is increased, then the drying speed is improved, but the shoe may be excessively dried

Engineering Contradiction:
Improvedrying speedVSAvoidexcessive drying
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system applies different blowing conditions to different regions of the shoe by adjusting the blowing direction to match the shoe's actual position, ensuring that air is concentrated on undried areas like the toe portion while avoiding already dried areas, thus achieving uniform drying without excessive heat exposure

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The rotatable blowing unit dynamically adjusts its direction based on real-time shoe position detection, allowing the system to maintain high drying efficiency by concentrating air flow on undried areas while preventing excessive drying in already treated areas

Inventive Principle:
Principle #15Dynamics

3Productivity

If the wind volume is increased, then the drying efficiency is improved, but the shoe may be excessively dried

Engineering Contradiction:
Improvedrying efficiencyVSAvoidexcessive drying
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system concentrates high-volume air flow precisely on the undried toe portion by adjusting the blowing direction according to shoe position, rather than dispersing it uniformly, thereby achieving high drying efficiency without causing excessive drying in already dried areas

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The image recognition system continuously monitors shoe position and provides feedback to adjust the blowing unit's direction, ensuring that high wind volume is always directed at the correct location (toe portion), maximizing drying efficiency while preventing damage to already dried areas

Inventive Principle:
Principle #23Feedback
