Solution Overview

Problem

Conventional window drying racks suffer from instability, potential breakage under wet laundry weight, and fixed sizes, which do not adapt to varying window dimensions, posing safety concerns and inefficiencies in space utilization.

Innovation Solution

A metal drying rack design featuring symmetrical elements with telescopic mechanisms, 'C' shaped supports, and horizontal rods that securely attach to roller shutter guides, allowing adjustable width and enhanced stability through a locking system, preventing inward deformation under heavy loads, and serving as a safety barrier.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional drying racks are attached to rails, then they can be removed and stored, but they suffer from instability and are not properly secured

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

Solution Approach 1:

The drying rack is divided into separate modular components: uprights, crossbars, and coupling devices. Each component can be independently assembled and disassembled, allowing easy installation and removal while maintaining stability through proper connection mechanisms.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A coupling device acts as an intermediary between the drying rack uprights and the window rail. This coupling device includes a clamping mechanism that securely grips the rail, providing stable attachment while allowing the entire rack to be easily installed and removed as a unit.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Quantity of substance

If drying racks are made to support wet laundry weight, then they can hold heavy loads, but they risk breakage or falling

Engineering Contradiction:
Improveload capacityVSAvoidstructural integrity
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The drying rack uses composite construction combining metal uprights for structural strength with plastic or coated metal crossbars for durability and corrosion resistance. This composite material approach ensures the rack can support heavy wet laundry loads without breaking or deforming.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The coupling device incorporates a safety mechanism that distributes the load of wet laundry across multiple contact points with the rail. The clamping structure is designed with sufficient safety margin to prevent sudden failure or falling even under maximum expected load conditions.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Ease of manufacture

If drying racks have fixed sizes, then they are simple to manufacture, but they cannot adapt to varying window dimensions

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidsize adaptability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The crossbars are designed as telescopic or adjustable length components that can be extended or retracted to match different window widths. This dynamic adjustment capability allows a single rack model to adapt to various window sizes while maintaining simple manufacturing processes for the modular components.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The rack is constructed from standardized modular segments (uprights, crossbars, connectors) that can be assembled in different configurations. This segmentation allows the same basic components to create racks of different sizes, providing adaptability without requiring custom manufacturing for each size.

Inventive Principle:
Principle #1Segmentation

4Ease of operation

If drying racks use simple attachment mechanisms, then they are easy to install, but they detach or fall off the rail

Engineering Contradiction:
Improveinstallation easeVSAvoidattachment security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The coupling device serves as an intermediary attachment mechanism between the rack uprights and the window rail. It features a clamping design with sufficient friction and mechanical interlocking to securely hold the rack in place, preventing detachment while still allowing relatively easy installation and removal by a single person.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The invention is a clothes drying rack comprising two symmetrical elements (bs, bd), each comprising at least one wire holding shelf (md, ms) assembled on an upright (cd, cs), and wherein one or preferably at least two horizontal rods (ad, as) are fixed at right angles to said upright (cd, cs), each one of said rods (ad, as) being suited to be fixed to the corresponding horizontal rods (as, ad) integral with the other opposing symmetrical element (bs, bd) and, wherein said uprights (cs, cd) are suitable for being inserted in the opposing guides of a roller shutter.
