Dehumidifier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dehumidifiers have handles that are prone to damage during movement due to their tilting or folding mechanism, which can lead to structural integrity issues.
Innovation Solution
The dehumidifier features a handle designed with a lifting member that includes a latch hook, a latch, a lock spring, and reduction gears, allowing the handle to be automatically raised and lowered, preventing external forces from damaging the handle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the handle is designed in a tilting or folding manner to be attached to the dehumidifier body, then the handle can be compact when not in use, but the handle is prone to damage during movement due to external forces
Solution Approach 1:
The handle is designed to dynamically change its position between a protruding state (when in use) and a retracted state (when not in use). The automatic lifting mechanism enables the handle to move between these states autonomously, allowing it to be compact during storage while maintaining structural integrity by avoiding exposure to external forces during movement.
Solution Approach 2:
The handle system includes an automatic lifting mechanism that operates without user intervention. When the dehumidifier is moved, the mechanism automatically raises the handle to a protected position, eliminating the need for manual handling of the handle and preventing damage from external forces during transport.
2Ease of operation
If the handle is erected by external force during movement, then the handle can be positioned for use, but the handle may be damaged in the process
Solution Approach 1:
The automatic lifting mechanism performs a preliminary action by raising the handle to a protected position before the dehumidifier is moved. This prevents the handle from being exposed to harmful external forces during transport, eliminating the need to erect the handle by external force and preventing potential damage.
Solution Approach 2:
The handle is automatically positioned in the required orientation and position before the user needs to use it. The lifting mechanism ensures the handle is ready for operation without requiring manual manipulation that could expose it to damage, combining ease of operation with protection from external forces.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The innovative handle design ensures that the handle is protected from external forces when not in use, maintaining its structural integrity and enhancing the overall durability of the dehumidifier.
Implementation Method 1
a lock spring (57) connecting the lifting guide (54) and the back cover (52) to generate a force to raise the lifting guide (54)
Implementation Method 2
reduction gears (55) to reduce a rising speed of the lifting guide (54)

AI summary
A dehumidifier is provided that may include a housing including a base, a case disposed on the base, and a top cover that covers an upper end of the case; a dehumidification module provided inside of the housing; and a handle mounted inside of the housing. The dehumidification module may include a compressor that compresses a refrigerant; a fan module; a condenser located at an inlet side of the fan module to condense the refrigerant that has passed through the compressor; an expansion valve that changes a phase of the refrigerant passing through the condenser; and an evaporator located at a rear side the condenser to evaporate the refrigerant that has passed through the expansion valve. The handle may include a front cover; a back cover coupled to a rear side of the front cover; a lifting guide accommodated in a space defined by the front cover and the back cover; a handle body coupled to an upper end of the lifting guide; and a lifting member that provide automatic raising of the handle body.
