Clothing drying device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing indoor clothing drying devices face challenges in compactness due to the need for large pulleys to accommodate a rope outlet on the front surface, which increases the device's thickness or height dimension.
Innovation Solution
A clothing drying device design featuring a drum with a rope wound around, a compact casing body with an entrance/exit surface adjacent to a wall, a gate-shaped guide member with arc surfaces and a spacer to secure space, and a receiving portion on a separate wall for the rope's grip, allowing for a compact configuration without a large pulley.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a large pulley is provided between the drum and the rope outlet on the front surface, then the rope can be guided smoothly, but the thickness dimension or height dimension of the cover case increases
Solution Approach 1:
The patent removes the traditional large pulley from the front surface of the cover case and extracts only the essential rope guidance function. The rope outlet is repositioned to the side surface, eliminating the need for a large front-mounted pulley and thereby reducing the cover case's thickness or height dimension.
Solution Approach 2:
The rope outlet is relocated from the front surface to the side surface of the cover case, changing the spatial dimension through which the rope exits. This dimensional shift allows the rope to be guided smoothly without requiring a large pulley that would increase the cover case's thickness or height.
2Ease of operation
If the rope outlet is provided on the front surface of the cover case, then the rope can be easily accessed, but a large pulley is required which increases device size
Solution Approach 1:
The rope outlet is positioned on the side surface of the cover case rather than the front surface, utilizing a different spatial dimension for rope access. This allows the rope to be easily accessed without requiring a large pulley, thereby reducing the overall device volume.
3Length of stationary object
If the cover case thickness is reduced for compactness, then the device becomes more space-efficient, but the structural strength may be compromised
Solution Approach 1:
The cover case is divided into multiple reinforcing ribs that segment the structure internally. These ribs provide structural strength and rigidity to the cover case, allowing the overall thickness to be reduced for compactness while maintaining the necessary structural integrity.
Solution Approach 2:
Reinforcing ribs are strategically positioned at specific locations within the cover case where structural strength is most needed. This localized reinforcement allows the cover case thickness to be reduced in non-critical areas while maintaining overall structural strength.
