Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shoe care devices face issues with maintaining a constant air temperature due to heat buildup, leading to thermal damage and inefficient dehumidification, especially in high outside air temperatures, and they often release contaminated air.
Innovation Solution
A shoe care apparatus with a heat pump cycle system that includes a compressor, evaporator, and condenser, controlled by a processor to manage air circulation and temperature, using a second fan to regulate compressor operation and maintain constant air temperature, while preventing heat buildup and air contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the compressor operates continuously to improve dehumidification performance, then dehumidification efficiency increases, but heat buildup causes thermal damage to shoes
Solution Approach 1:
The patent introduces a second fan as an intermediary device located in the machine room to circulate air and dissipate heat generated by the compressor. This mediator prevents direct thermal transfer from the compressor to the shoe care chamber, allowing the compressor to operate at high capacity for improved dehumidification while the second fan actively manages the harmful heat buildup through continuous air circulation and heat dissipation.
2Stability of the object's composition
If air is continuously circulated through the chamber to maintain constant temperature, then temperature stability improves, but heat buildup occurs due to continuous compression
Solution Approach 1:
The patent divides the air circulation system into two separate pathways: a first fan that circulates air through the shoe care chamber to maintain temperature stability, and a second fan that circulates air specifically in the machine room to manage heat buildup. This segmentation allows independent control of temperature stability and heat dissipation functions, enabling continuous operation without thermal damage.
3Productivity
If the operating rate of the compressor is increased in high outside air temperature environments, then dehumidification efficiency improves, but the usable temperature range is limited
Solution Approach 1:
The patent implements dynamic control of the second fan's operation based on real-time monitoring of compressor operation state and outside air temperature. The processor adjusts the second fan's activation and speed dynamically, increasing its operation during high-temperature conditions when the compressor works harder, and reducing it when conditions are favorable. This dynamic adaptation allows the system to maintain high dehumidification efficiency across a broader usable temperature range.
