Double-Decker Cloth Rack with Tri-Connect Couplers for Load Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustable double-decker cloth racks are not structurally strong enough, leading to instability and potential damage when carrying heavy loads, causing the rack to become shaky and potentially collapse.
Innovation Solution
A double-decker cloth rack design featuring a reinforced structure with tri-connect couplers, locking nuts, and telescopic extension pieces to enhance stability, including a base with horizontal slats and transverse supports, and end caps to secure the vertical and horizontal tubes, ensuring the rack can handle heavy loads without collapsing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the cloth rack uses a simple structure with basic connections, then it is easy to manufacture and assemble, but it lacks structural strength and becomes shaky when bearing heavy loads
Solution Approach 1:
The vertical tubes are divided into multiple sections (top tube and bottom tube) that can be telescopically adjusted, allowing the rack to be customized for different heights while maintaining structural integrity through segmented design
Solution Approach 2:
The extension piece is inserted within the top horizontal tube, creating a nested structure that provides additional support and reinforcement without significantly increasing the overall footprint of the rack
Solution Approach 3:
The locking nut is pre-positioned on the helical track of the tri-connect coupler, allowing for easy adjustment and locking of the vertical tube position before use, ensuring proper structural alignment is achieved during assembly
2Adaptability or versatility
If the cloth rack uses adjustable components for versatility, then it can adapt to different storage needs, but it becomes less stable when fully extended and loaded
Solution Approach 1:
The rack provides dynamic adjustability through telescopic vertical tubes with locking mechanisms and adjustable horizontal tubes, allowing users to customize the rack configuration based on storage needs while maintaining stability through secure locking features
Solution Approach 2:
Different sections of the rack have different degrees of adjustability - the vertical tubes offer height adjustment while the horizontal tubes provide reach adjustment, with each section optimized for its specific function while contributing to overall stability
3Force
If the cloth rack uses plastic base and coupler connections, then it is lightweight and easy to assemble, but it suffers from damage to the base and separation of couplers when bearing maximum load
Solution Approach 1:
The tri-connect coupler integrates multiple connection functions into a single component, combining the horizontal tube connection, vertical tube attachment, and locking mechanism into one unified structure that simplifies assembly while strengthening connections
Solution Approach 2:
The rack combines different materials strategically - metal components for structural elements requiring strength (vertical tubes, couplers, locking nuts) and plastic for the base and non-critical components, creating a composite structure that balances weight, ease of manufacture, and load-bearing capacity
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 design significantly improves the structural integrity of the cloth rack, preventing shakiness and damage, even when fully loaded, by securely connecting the horizontal and vertical tubes, thus maintaining stability and preventing collapse.
Implementation Method 1
a locking nut to screw onto the helical track to decrease the divide of the slit, thereby tightening the horizontal tube body
Implementation Method 2
a locking nut to screw onto the helical track
Implementation Method 3
The extension piece telescopically inserts within the perspective terminal end of the top horizontal tube
