Solution Overview

Problem

Existing boot drying devices are bulky, non-portable, and limited in capacity, often accommodating only one or two pairs of boots or gloves, failing to meet the need for a compact, efficient, and modular solution that can dry multiple items simultaneously and adapt to various spatial requirements.

Innovation Solution

A portable modular dryer device equipped with a fan unit that distributes air and heat through a drying manifold, featuring interchangeable attachments for boots and gloves, and a modular design allowing for easy assembly, disassembly, and mounting on walls, enabling the simultaneous drying of multiple pairs of boots and gloves.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Weight of moving object

If prior art boot drying structures are used, then they can dry boots and gloves, but they are bulky and non-portable

Engineering Contradiction:
ImproveportabilityVSAvoidbulkiness
Core Design Contradiction:
Weight of moving objectVSVolume of stationary object

Solution Approach 1:

The drying device is divided into modular components including a fan unit, heating element, and interchangeable drying attachments that can be assembled and disassembled. This segmentation allows the device to be compact for storage and transport while providing sufficient drying capacity when assembled.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The fan unit serves multiple functions by being able to attach different drying attachments for various items (boots, gloves, shoes, hats). The single fan unit can service multiple attachments, reducing the overall volume needed compared to having separate drying devices for each item type.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Quantity of substance

If prior art boot drying structures are used, then they can dry one or two pairs of boots, but they cannot accommodate multiple items simultaneously

Engineering Contradiction:
Improvenumber of items driedVSAvoidstructural complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The drying system uses separate interchangeable attachments for different item types (boot attachments, glove attachments, shoe attachments) that can be selectively attached to the fan unit. This allows multiple items to be dried simultaneously by having multiple attachments connected to the single fan unit, increasing capacity without proportionally increasing overall device complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The fan unit is designed as a universal base that can accommodate multiple types of drying attachments. A single fan unit can service multiple attachments for boots, gloves, shoes, and hats simultaneously, allowing the device to handle a greater variety and quantity of items without requiring separate dedicated devices for each item type.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If prior art boot drying structures are used, then they have fixed construction, but they cannot adapt to different spatial requirements

Engineering Contradiction:
Improvespatial adaptabilityVSAvoidmodular design complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device is constructed from modular components including a fan unit, heating element, and various drying attachments that can be assembled in different configurations. The attachments can be selectively attached or removed based on what needs to be dried and the available space, allowing adaptation to different spatial requirements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The drying device incorporates flexible positioning capabilities where attachments can be adjusted and repositioned. The modular design allows the user to configure the device according to available space and drying needs, making it dynamically adaptable rather than fixed in a single configuration.

Inventive Principle:
Principle #15Dynamics
