Drawer-Type Laundry Apparatus with Mountable Unit Interlock Control
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 lower than waist level, and existing solutions do not address the operational functionality effectively.
Innovation Solution
A laundry treatment apparatus with a detachable second treatment apparatus mounted on the upper surface, featuring a connector unit that controls the operation of the driving unit and display unit only when the second apparatus is present, preventing unauthorized operation and ensuring stability by requiring the second apparatus to be mounted for functionality.
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 apparatus cannot perform laundry treatment functions
Solution Approach 1:
The support platform is designed to serve dual purposes: it acts as a structural support to raise the introduction port height for user convenience, and simultaneously functions as a laundry treatment apparatus with its own drum and driving unit. This multi-functionality resolves the contradiction by making the support structure itself capable of performing laundry treatment.
Solution Approach 2:
The patent combines two separate functions into one integrated system: the support platform structure and the laundry treatment apparatus. By merging these functions, the introduction port height is raised while the laundry treatment capability is preserved and enhanced through the integrated second drum system.
2Reliability
If the connector unit prevents operation when the object is absent, then operational stability is improved, but device complexity increases
Solution Approach 1:
The connector unit automatically detects whether the second laundry treatment apparatus is mounted on the first apparatus and autonomously controls the opening or closing of the circuit accordingly. This self-service mechanism eliminates the need for complex external control systems while ensuring operational stability through automatic detection and response.
Solution Approach 2:
The patent replaces complex mechanical interlocking systems with an electrical circuit control system. The connector unit uses electrical signals to detect the presence of the second apparatus and control the driving unit operation, simplifying the overall system while maintaining reliability through electronic detection and control mechanisms.

AI summary
A laundry treatment apparatus includes a cabinet having an upper surface, the upper surface being configured to receive an object thereon, a drawer adapted to be drawn from the cabinet, a drum disposed in the drawer and defining a space for receiving laundry, a driving unit configured to rotate the drum, a control unit configured to control the driving unit, and a connector unit configured to impact an ability of the control unit to control operation of the driving unit based on whether or not the object is placed on the upper surface of the cabinet by preventing the control unit from controlling operation of the driving unit based on the object being absent from the upper surface of the cabinet and by allowing the control unit to control operation of the driving unit based on the object being placed on the upper surface of the cabinet.
