Solution Overview

Problem

Existing ozone generators used for deodorizing and sanitizing clothing and shoes require prolonged operation and are not suitable for home use due to their size and inefficiency in generating and transporting ozone, necessitating on-site generation and circulation.

Innovation Solution

A deodorizing and sanitizing apparatus with an enclosed treatment zone, an ozone generator, and a ventilation assembly that creates ozone-laden air currents by drawing ambient air past the generator, with a fan and optional heating to efficiently deodorize and sanitize items like shoes, where the ozone generator is located outside the treatment zone to enhance ozone concentration and delivery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If existing ozone generators are used for deodorizing and sanitizing clothing and shoes, then deodorizing and sanitizing function is achieved, but treatment time is prolonged and device size becomes too large for home use

Engineering Contradiction:
Improvetreatment speedVSAvoidoperation duration
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The apparatus is divided into distinct functional zones: an ozone generation compartment separated from the treatment chamber by a partition wall. This segmentation allows the ozone generator to operate in a confined space while delivering ozone-laden air to the treatment zone, improving treatment efficiency without requiring the entire device to be oversized.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A fan acts as an intermediary device to transport ozone-laden air from the generation compartment to the treatment chamber. This mediator enables efficient ozone distribution throughout the treatment space, accelerating the deodorizing and sanitizing process compared to passive diffusion methods.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Quantity of substance

If ozone generator is placed inside the treatment zone, then ozone is generated in-situ, but ozone concentration and delivery efficiency are reduced

Engineering Contradiction:
Improveozone concentrationVSAvoidgenerator placement configuration
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The treatment chamber is partitioned into two separate compartments: an ozone generation compartment and a treatment compartment. The partition wall with openings allows ozone-laden air to pass from the generation compartment to the treatment compartment, maintaining high ozone concentration while simplifying the overall device structure through functional separation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The partition wall serves as an intermediary structure that facilitates ozone transfer between compartments. The openings in the partition wall allow ozone-laden air to flow from the generation compartment to the treatment compartment, enabling efficient ozone delivery without requiring the generator to be placed inside the treatment zone.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If ambient air is drawn into proximity with ozone generator, then ozone-laden air currents are created efficiently, but additional ventilation components increase device complexity

Engineering Contradiction:
Improveozone generation efficiencyVSAvoidventilation assembly structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The ventilation functions are merged into a single integrated fan assembly that performs multiple tasks: drawing ambient air into the generation compartment, circulating ozone-laden air through the treatment chamber, and maintaining positive pressure. This consolidation improves ozone generation efficiency while minimizing the increase in device complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The fan assembly serves multiple functions simultaneously: it acts as an air intake device, an ozone distribution pump, and a pressure regulation mechanism. This multi-functionality enables efficient ozone-laden air current creation without requiring separate components for each function, thereby limiting the increase in device complexity.

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

AI summary

Improved, portable apparatus for ozone deodorizing and sanitizing of clothing items such as shoes is provided having a housing sized to receive an item to be treated, together with an ozone generator and a ventilation assembly operable to deliver ozone-laden air currents into the housing. In preferred forms, the ozone generator is located within a compartment separate from the housing, and a fan assembly is used to draw ambient air currents adjacent the generator for ozone supplementation, followed by delivery of the ozone-laden air currents into the housing.
