Retractable Laundry Drawer With Guided Water Supply Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Front-loading laundry treatment apparatuses are inconvenient due to the need for users to stoop when loading or unloading laundry, as the introduction port is positioned below waist level, and existing support platforms do not facilitate laundry treatment functions.
Innovation Solution
A detachable laundry treatment apparatus with a retractable drawer and accommodation unit that allows for easy supply and discharge of washing water, condensation of moisture, and circulation within the unit, featuring a guider system with internal and external water supply and discharge channels, and a recovery unit to manage moisture discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a support platform is added to raise the introduction port height, then user convenience is improved, but the platform cannot perform laundry treatment functions
Solution Approach 1:
The retractable drawer is designed to serve dual purposes: it raises the introduction port height for user convenience while simultaneously providing an accommodation unit capable of performing laundry treatment functions such as washing or drying small items. This multi-functional design resolves the contradiction by making a single structure serve both ergonomic and functional needs.
2Adaptability or versatility
If a retractable drawer with accommodation unit is provided, then laundry treatment function is added, but water supply and discharge becomes complex
Solution Approach 1:
The patent utilizes flexible water supply channels that can bend and extend as the drawer moves in and out. This flexible connection allows water to be supplied to the moving accommodation unit without requiring complex rigid piping, telescoping joints, or rotary couplings, thereby adding functionality while keeping the water supply system relatively simple.
3Productivity
If washing water is discharged from the accommodation unit, then washing function is completed, but water may remain in the discharge unit causing equipment failure
Solution Approach 1:
The discharge unit is designed with a self-draining structure that uses gravity to automatically drain washing water from the accommodation unit and discharge channel after the washing cycle completes. This self-service draining mechanism eliminates the need for additional pumps or manual intervention to remove residual water, thereby preventing equipment failure from water accumulation while maintaining efficient washing cycle completion.
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
Enhances user convenience by allowing easy loading and unloading of laundry while performing washing and drying functions efficiently, minimizing water loss and preventing water from remaining in discharge units, thus improving washing performance and reducing the risk of equipment failure.
Implementation Method 1
A water supply channel is provided along the guider and is configured to supply water between the supply unit and the accommodation unit
