Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dehumidifiers have a small water tank size, leading to frequent water pouring by users, which affects user experience.
Innovation Solution
A dehumidifier design that includes a mounting bracket with a liquid level detector and a water pump assembly, where the suction pipe is positioned at the bottom of the water tank, allowing for automatic drainage based on water level detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the water tank size is increased, then the water storage capacity is improved, but the device complexity increases
Solution Approach 1:
The water tank is divided into a first water tank and a second water tank, with the first water tank having a larger capacity for bulk water storage and the second water tank being smaller and positioned higher for automatic drainage functionality. This segmentation allows the system to achieve large total water capacity while maintaining manageable complexity through functional division of the water storage system.
2Ease of operation
If automatic drainage is implemented, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The second water tank is positioned higher than the first water tank, utilizing gravity to enable automatic drainage of condensed water from the first tank to the second tank and then to the drainage outlet. This self-service mechanism eliminates the need for active pumping or complex control systems, achieving automatic drainage functionality while minimizing device complexity.
3Extent of automation
If the water tank is positioned higher, then the automatic drainage capability is improved, but the volume of the water tank is reduced
Solution Approach 1:
The water storage system is segmented into two tanks at different heights: the first water tank with larger volume positioned lower for bulk storage, and the second water tank with smaller volume positioned higher for automatic drainage. This segmentation resolves the contradiction by allocating different volumes to tanks based on their functional requirements rather than using a single high-positioned tank.
