Solution Overview
Problem
Conventional shoes care devices fail to properly dehumidify and deodorize shoes, with moisture and odor-laden air being discharged into the environment, leading to reduced performance and user dissatisfaction, and lack effective regeneration and management of dehumidifying materials.
Innovation Solution
A shoes care device with a dehumidifying part that regenerates used dehumidifying material, utilizing a circulation air current structure to dehumidify and deodorize shoes within an inner cabinet, and automatically terminate processing based on temperature differences to ensure complete treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If air is discharged to the outside of the apparatus after passing through the deodorization module, then moisture and odors can be removed from the shoes, but the air that has not sufficiently removed moisture or odors may be discharged to the inside where the wearer resides
Solution Approach 1:
Instead of discharging air to the outside, the patent inverts the approach by recirculating the air back into the treatment chamber. The air that has passed through the deodorization module is not discharged externally but is redirected to continue circulating through the shoes, ensuring repeated treatment and sufficient removal of moisture and odors before any discharge occurs.
Solution Approach 2:
The patent implements continuous circulation of air through the shoes and deodorization module. The air is continuously pumped from the treatment chamber, passed through the deodorization module, and returned to the chamber, creating a continuous cycle that ensures thorough and sustained dehumidification and deodorization without interrupting the treatment process.
2Reliability
If dehumidifying materials are used to remove moisture from air, then shoe treatment performance can be improved, but the performance of the dehumidifying material reduces over time and requires regeneration
Solution Approach 1:
The patent implements a regeneration system that recovers the dehumidifying material's effectiveness. When the dehumidifying material becomes saturated and loses performance, the system activates a regeneration mode that heats the material to desorb the absorbed moisture, restoring its dehumidification capability and allowing it to be used again without replacement.
Solution Approach 2:
The patent changes the temperature parameter of the dehumidifying material during regeneration. By heating the material to a higher temperature, the absorbed moisture is desorbed and removed, thereby changing the material's moisture content parameter and restoring its dehumidifying performance for continued use.
3Reliability
If air circulation is used to treat shoes, then dehumidification and deodorization can be achieved, but the processing time and energy consumption increase
Solution Approach 1:
The patent employs periodic action by implementing automatic control that monitors treatment progress and terminates the circulation process when predetermined conditions are met. The system operates in cycles, pumping air through the shoes and deodorization module, then pausing to assess whether treatment objectives have been achieved, thereby reducing unnecessary processing time and energy consumption.
Solution Approach 2:
The patent incorporates feedback control mechanisms that monitor the treatment process and provide information to the control system. Based on this feedback regarding moisture levels and treatment effectiveness, the system automatically adjusts or terminates the air circulation process, optimizing processing time and energy usage while ensuring adequate shoe treatment.

AI summary
A shoes care device includes: an inner cabinet having an accommodation space configured to accommodate shoes; a connection path providing a flow path through which air from the accommodation space is introduced and then discharged back into the accommodation space; a blowing part; a dehumidifying part; a controller configured to control a drying stroke in which air moves along the connection path and is dehumidified to dry the accommodation space; a first sensor disposed upstream of the dehumidifying part to measure a temperature of the air; and a second sensor disposed downstream from the dehumidifying part to measure a temperature of the air. The controller is configured to control the drying stroke to be performed until a state in which completion of processing of the shoes is estimated through a difference of the temperatures of air measured by the first sensor and the second sensor during the drying stroke.
