Stacked Laundry Drums With Remote Control and Vibration Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry treatment apparatuses face challenges in reducing their volume, leading to space inefficiencies when multiple units are required, as they need to accommodate a minimum laundry capacity, resulting in users needing to place them side by side, which worsens space utilization.
Innovation Solution
A laundry treatment apparatus design where multiple treatment devices, each capable of washing or drying, are stacked vertically, with a remote control system allowing operation of lower devices from the top unit, including a connector that enables power and control circuit activation only when the top unit is properly seated, ensuring synchronized operation and minimizing vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple laundry treatment devices are placed side by side to provide multiple treatment functions, then the laundry treatment capability is improved, but the space occupied increases
Solution Approach 1:
The patent transitions from horizontal placement (side by side) to vertical stacking (one above another), utilizing the vertical dimension to accommodate multiple laundry treatment devices. This dimensional change allows multiple devices to occupy a smaller floor area while maintaining their individual treatment functions, effectively resolving the contradiction between versatility and space occupation.
Solution Approach 2:
The patent implements a nested configuration where one laundry treatment device is positioned inside or integrated with another device vertically. The upper device can be nested within the structural framework of the lower device, allowing both devices to function simultaneously while occupying minimal space, similar to nested dolls.
2Area of stationary object
If laundry treatment devices are stacked vertically to reduce space, then the space efficiency is improved, but the control complexity increases
Solution Approach 1:
The patent implements a universal remote controller that can operate both the upper and lower laundry treatment devices through a single interface. This multi-functional control system eliminates the need for separate controls for each stacked device, reducing control complexity despite the vertical stacking configuration.
Solution Approach 2:
The remote controller serves as an intermediary device that mediates between the user and multiple stacked laundry treatment devices. It provides a unified interface for controlling both upper and lower devices, simplifying the control architecture and reducing operational complexity while maintaining vertical stacking for space efficiency.
3Area of stationary object
If laundry treatment devices are stacked vertically, then the space utilization is improved, but the vibration and noise increase
Solution Approach 1:
The patent utilizes the vibration isolation mechanism where the upper laundry treatment device acts as a vibration damper for the lower device. The natural vibrations of the upper device counteract and reduce the vibrations generated by the lower device, converting a potential harmful effect into a beneficial vibration reduction mechanism that mitigates noise and vibration in the stacked configuration.
