Solution Overview

Problem

Laundry drying racks face stability issues due to high static load from damp laundry, leading to tipping over, especially when placed away from the center of gravity, which can cause accidents and contamination of freshly washed items.

Innovation Solution

Incorporating magnetic holding elements on the base structure of the drying rack, allowing reversible attachment to surfaces via magnetic interaction, enhancing stability and preventing tipping.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the drying rack uses a freestanding base structure with feet filled with water or sand to prevent tipping, then stability is improved, but the device becomes heavy and difficult to move

Engineering Contradiction:
ImprovestabilityVSAvoidweight
Core Design Contradiction:
Stability of the object's compositionVSWeight of stationary object

Solution Approach 1:

The patent replaces the mechanical stabilization system (feet filled with water or sand) with a magnetic field-based stabilization system. Magnetic holding elements are integrated into the base structure, which interact with ferromagnetic surfaces to provide stabilization forces without adding significant weight to the device.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the physical state of the stabilization mechanism from a passive mechanical system (weight-based) to an active magnetic field-based system. By utilizing magnetic field strength as the stabilizing parameter instead of mass, the device achieves stability without the penalty of increased weight.

Inventive Principle:
Principle #35Parameter changes

2Stability of the object's composition

If adhesive or suction cup devices are used to attach the drying rack to surfaces, then stability is improved, but the attachment cannot be securely and permanently fixed to all types of surfaces

Engineering Contradiction:
ImprovestabilityVSAvoidsurface compatibility
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The magnetic holding elements provide a universal attachment solution that works with any ferromagnetic surface (metal surfaces, magnetic tiles, etc.). This single magnetic-based mechanism replaces multiple specialized attachment methods (adhesive, suction cups) and provides consistent performance across different ferromagnetic surfaces without requiring surface-specific customization.

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

3Ease of operation

If the drying rack is designed to be foldable for space-saving storage, then ease of storage is improved, but stability and resistance to tipping are worsened

Engineering Contradiction:
Improvestorage convenienceVSAvoidstability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent replaces the mechanical stabilization system (which would be difficult to implement in foldable structures) with a magnetic field-based system. The magnetic holding elements can be integrated into the foldable base structure, providing stabilization forces that work effectively regardless of the folded or unfolded state, enabling space-saving storage without compromising stability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Area of stationary object

If extension frames are added to increase drying area, then drying capacity is improved, but the risk of tipping over increases due to laundry positioned far from the center of gravity

Engineering Contradiction:
Improvedrying areaVSAvoidstability
Core Design Contradiction:
Area of stationary objectVSStability of the object's composition

Solution Approach 1:

The magnetic holding elements act as counterbalancing forces that oppose the tipping moment created by laundry positioned on extension frames far from the center of gravity. The magnetic attraction forces provide a stabilizing torque that counteracts the destabilizing torque from the extended laundry load, enabling safe use of extended drying areas.

Inventive Principle:
Principle #8Anti-weight (Counterweight)
