Rotary clothes drier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rotary clothes dryers require users to bend down to operate the lift device due to the low positioning of the hoisting line, and they are prone to dirt, moisture, or small animals entering the standpipe when open, leading to functional restrictions and potential damage.
Innovation Solution
A sliding element is positioned above the sliding joint during the opening movement, allowing a higher deflection point for the lifting line and covering the openings in the standpipe wall when the dryer is open, thus reducing the need for users to bend and preventing contaminants from entering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the hoisting line is attached directly to the sliding joint, then the structure is simple, but the user must bend down to operate it which reduces ease of operation
Solution Approach 1:
A sliding element is introduced as an intermediary component between the standpipe and the sliding joint. This sliding element carries the hoisting line attachment point at a higher position, allowing users to operate the dryer without bending down, while the sliding element itself moves synchronously with the sliding joint to maintain functional simplicity.
2Adaptability or versatility
If the standpipe has openings for functional mechanisms, then the mechanism can access external components, but dirt and moisture can enter the standpipe interior causing damage
Solution Approach 1:
The sliding element acts as a flexible barrier that covers the openings in the standpipe wall during operation. As the sliding element moves up and down with the sliding joint, it dynamically seals the openings, preventing dirt and moisture from entering the standpipe interior while still allowing the functional mechanisms to access external components when needed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution elevates the hoisting line's end to a more comfortable gripping height, enhancing user convenience and reducing the risk of dirt, moisture, or small animals entering the standpipe, thereby improving the operational ease and longevity of the dryer.
Implementation Method 1
a sliding element which precedes the sliding joint during at least part of the opening movement is arranged above the sliding joint
Implementation Method 2
allowing a higher deflection point for the lifting line

AI summary
The dryer (1) has a slip joint (3) displaceably mounted along a stand pipe (2) for opening the dryer. Support arms (4) of the dryer are hinged at the slip joint. The slip joint is transferred from a lower position into an upper position by actuating a lifting device i.e. lifting cord. The dryer is closed in the lower position and opened in the upper position. A sliding element is arranged above the slip joint and runs ahead of the slip joint by a part of an opening movement. Openings are formed in a region of an upper end of the pipe. The sliding element is formed by a slip joint projection.
