Twin Laundry Apparatus Top Cover Design for Compact Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing laundry treating apparatuses face challenges in manufacturing and assembly due to space constraints, particularly in designing a twin laundry treating apparatus with separate washing and drying capabilities, where components must be compactly arranged and assembled in a limited space.
Innovation Solution
The proposed solution involves a laundry treating apparatus with a housing that includes a tub and a drum, a top cover with integrated detergent and water supply systems, and a distributor for distributing washing water, allowing for easy assembly and manufacturing by fixing components like detergent boxes and water supply pipes within the top cover before it covers the tub and drum, and forming a simple configuration with front and rear sidewalls to receive the tub and drum.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a twin laundry treating apparatus is designed with separate washing and drying portions, then the functionality and versatility are improved, but the device complexity and manufacturing difficulty increase due to limited space
Solution Approach 1:
The apparatus is divided into a washing machine portion and a dryer portion, each with separate tubs and drums. The top cover is segmented into a washing machine top cover and a dryer top cover, allowing independent assembly and manufacturing of each functional unit, thereby reducing overall complexity while maintaining versatility
Solution Approach 2:
The dryer portion is positioned above the washing machine portion, with the dryer tub and drum nested within the space above the washing machine tub. The dryer top cover is positioned above the washing machine top cover, creating a compact vertical arrangement that fits both functions in a limited footprint
2Volume of moving object
If the auxiliary washing machine is made smaller to fit in limited space, then the compactness is improved, but the ease of manufacture deteriorates due to difficulty in arranging and assembling components
Solution Approach 1:
The top cover is divided into separate washing machine and dryer portions that can be manufactured independently. Each top cover portion has pre-formed openings and mounting structures that simplify assembly of water supply pipes, detergent boxes, and other components in the compact space
Solution Approach 2:
The water supply pipes, detergent boxes, and other components are arranged and connected to the top cover portions before final assembly. The top cover openings are pre-positioned to align with component locations, allowing for easier connection and assembly in the limited space of the compact apparatus
3Volume of moving object
If components are arranged compactly in limited space, then the compactness is improved, but the reliability deteriorates due to potential water or detergent entry into control components
Solution Approach 1:
Control components are separated from the water-filled compartments and positioned in protected locations away from direct water and detergent exposure. The top cover structure creates physical barriers that extract control components from the hazardous wet environment while maintaining compact overall dimensions
Solution Approach 2:
The top cover structure acts as an intermediary barrier between water/detergent compartments and control components. Seals and protective structures in the top cover prevent water and detergent from reaching control components while allowing the apparatus to maintain a compact form factor

AI summary
A laundry treating apparatus includes a housing, a tub, a drum, a top cover located above the housing and configured to cover an upper portion of the tub and the drum, a detergent box, a distributor configured to receive washing water from an external water supply source and to distribute washing water, a detergent water supply pipe connected to the distributor, and a tub water supply pipe connected to the distributor. The top cover includes a distributor holder located at a rear portion of the top cover and configured to support the distributor, a detergent box holder located at a front portion of the top cover and configured to support the detergent box, and a first pass through that allows the detergent water supply pipe to pass through the top cover from an upper portion of the top cover to a lower portion of the top cover.
