Solution Overview

Problem

Existing laundry drying devices are bulky, require frequent setup and teardown, and either occupy valuable space or obstruct windows when not in use, lacking a space-saving and user-friendly design.

Innovation Solution

A horizontally swiveling laundry drying device with rectangular sash frames and hinges, allowing it to pivot horizontally within a window or door frame, maintaining a compact closed position and expanding for use without obstructing the window or door when open.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a laundry drying device is attached to a wall, then it provides stable support for drying laundry, but it becomes bulky and occupies space even when closed

Engineering Contradiction:
Improvestable supportVSAvoidspace occupied when closed
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The drying device is nested within the window frame structure, with the sash frame fitting inside the window opening. When closed, the device occupies the same space as the window frame itself, effectively hiding it within the building structure rather than protruding outward like traditional wall-mounted racks.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Area of stationary object

If a laundry drying device is attached in front of a window, then it saves wall space, but the window can no longer be opened or only partially opened

Engineering Contradiction:
Improvewall space savedVSAvoidwindow opening capability
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The device incorporates a hinge mechanism with vertical rotation axis that allows the sash frame to pivot horizontally. This dynamic design enables the window to open freely while the drying device can be rotated out of the way when not in use, eliminating the static obstruction problem of traditional window-mounted racks.

Inventive Principle:
Principle #15Dynamics

3Volume of moving object

If a laundry drying device is designed to be compact when closed, then it saves space, but it requires frequent setup and teardown to be used

Engineering Contradiction:
Improvespace occupied when closedVSAvoidsetup and teardown frequency
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The horizontal pivoting mechanism allows the device to transition smoothly between closed and open positions without requiring complete disassembly or setup. Users can simply rotate the sash frame horizontally to deploy or stow the drying racks, eliminating the labor-intensive setup and teardown processes of traditional collapsible racks.

Inventive Principle:
Principle #15Dynamics

4Area of stationary object

If a laundry drying device uses horizontal pivoting mechanism, then it allows window operation and saves space, but the structure becomes more complex

Engineering Contradiction:
Improvespace efficiencyVSAvoidstructure complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The hinge mechanism serves multiple functions: it enables the horizontal pivoting motion, provides the mounting connection to the window frame, and allows the device to be positioned at various angles. This multi-functional design reduces the need for separate complex mechanisms for each function, simplifying the overall structure despite the sophisticated motion capabilities.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The invention relates to a horizontally pivotable laundry drying device (1) for mounting on or in front of an inside of a horizontally pivotable window frame (10) or on or in front of a horizontally pivotable door, comprising at least one rectangular sash frame (2, 2') made of two vertical longitudinal struts (3) and two horizontal transverse struts (4), wherein several vertically spaced horizontal bars (5) are arranged between the two vertical longitudinal struts (3) of the at least one rectangular sash frame (2, 2'), wherein at least one hinge (6) with a vertical axis of rotation is fixedly connected to one of the two vertical longitudinal struts (4) of the at least one rectangular sash frame (2, 2'); wherein, for the horizontal pivotability of the laundry drying device (1), the at least one hinge (6) can be attached to a vertical reveal (11) in a window opening (12) or door opening of a building.
