Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional collapsible garment drying racks are often too small to accommodate large loads and lack stability, making them inefficient for indoor use in spaces with limited storage.
Innovation Solution
A foldable and expandable garment drying rack design featuring interlocking frames with a gearing mechanism, crossbars that can telescope, and a locking system to adjust angles, allowing for increased capacity and stability while minimizing storage space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the drying rack is made collapsible to reduce storage space, then storage space is reduced, but the rack size when expanded is also reduced, limiting garment capacity
Solution Approach 1:
The drying rack is divided into multiple expandable sections with telescoping crossbars. Each section can be independently extended, allowing the rack to segment into a larger configuration when needed for drying garments, while collapsing into a compact form for storage. This segmentation enables the rack to achieve both small storage volume and large garment capacity at different times.
Solution Approach 2:
The rack employs dynamic telescoping crossbars and adjustable legs that can transition between retracted and extended positions. This dynamic structure allows the rack to adapt its size - compact when collapsed for storage, and expanded when needed to accommodate large garment loads, resolving the contradiction between storage efficiency and drying capacity.
2Quantity of substance
If the drying rack is made expandable to accommodate large loads, then garment capacity is increased, but the rack becomes more complex and harder to store
Solution Approach 1:
The telescoping crossbars are designed with nested sections that slide within one another, similar to nested dolls. When collapsed, the crossbars nest within each other to minimize space and simplify the structure for storage. When expanded, the nested sections extend to provide the necessary garment capacity, thus reducing structure complexity when not in use while maintaining high capacity when needed.
Solution Approach 2:
The rack uses dynamic telescoping mechanisms that allow the crossbars to transition smoothly between extended and retracted states. This dynamic design enables the structure to simplify itself during storage without permanently compromising its expanded capacity, effectively managing the trade-off between complexity and functionality.
3Quantity of substance
If the drying rack uses a telescoping crossbar system to increase capacity, then garment capacity is increased, but the mechanism becomes more complex
Solution Approach 1:
The crossbar mechanism employs nested telescoping sections that slide within each other using simple friction-fit or pinned connections. This nesting approach increases garment capacity when extended while keeping the mechanism relatively simple and intuitive to operate, avoiding overly complex mechanical systems.
Solution Approach 2:
The telescoping crossbars are designed to be easily extended and retracted by the user without requiring complex locking mechanisms or tools. The self-service design allows users to adjust the crossbar length themselves to match their drying needs, simplifying the overall mechanism while maintaining increased capacity functionality.
4Ease of operation
If the drying rack is designed to be portable and foldable, then ease of movement is improved, but stability during use may be compromised
Solution Approach 1:
The rack features dynamically adjustable legs with locking mechanisms that can be extended to provide a wide base for stability during use, then collapsed for portability when not in use. The locking mechanism ensures the legs remain fixed at the desired angle during drying, providing stability, while the ability to collapse them maintains ease of movement and portability.
Solution Approach 2:
The frame is segmented into multiple adjustable sections connected by joints that allow the rack to be folded for transport but locked into a stable configuration during use. This segmentation enables the rack to transition between portable and stable states, with each segment capable of independent adjustment to optimize both portability and stability as needed.

AI summary
A collapsible drying rack for drying wet garments is provided. The drying rack preferably includes a right and a left frame, with each frame including a top and a bottom leg. Crossbars on which garments may be hung connect the left and right frames to one another. The top and bottom legs of each frame are engaged to one another at a joint that that allows the legs to be placed at a variety of angles relative to one another. Each joint also may include a locking member that keeps the legs at a particular angle relative to one another, including a 0° angle so that the rack can be collapsed and compactly stored when not in use.
