Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional racks are often large, awkward, and fixed, making them difficult to transport and use in various settings, necessitating a portable, collapsible, and adjustable storage solution.
Innovation Solution
A collapsible rack design featuring interlocking supporting and connecting members with pivotally connected rods and fabrics, allowing for easy assembly and disassembly by changing rod configurations from linear to V-shaped, significantly reducing size and enabling stacking for increased storage capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional racks are designed to be large and fixed, then storage capacity is improved, but portability and ease of transport deteriorate
Solution Approach 1:
The rack is divided into multiple supporting members (first supporting member, second supporting member) that can be independently collapsed. Each supporting member contains supporting rods that can be pivoted between extended and retracted positions, allowing the rack to be segmented into collapsible units that maintain storage capacity when assembled but reduce size for transport.
Solution Approach 2:
The rack employs dynamic structures where supporting rods can be pivoted between different positions using connectors. The holding rod mechanism allows dynamic transformation from an extended storage configuration to a collapsed transport configuration, enabling the rack to adapt its size while maintaining structural integrity and storage functionality.
2Stability of the object's composition
If conventional racks are designed to be fixed and stable, then structural stability is improved, but ease of assembly and disassembly deteriorates
Solution Approach 1:
The connectors are designed with pivotal connections that allow supporting rods to be easily rotated between locked and unlocked positions. This dynamic mechanism provides structural stability when the rack is assembled (rods in extended position) while enabling easy assembly and disassembly through simple rotational movements of the holding rod and connectors.
Solution Approach 2:
The collapsing mechanism is designed to be self-contained, where the holding rod simultaneously controls multiple connectors through its pivotal movement. When the holding rod is rotated, it automatically triggers the collapse of multiple supporting rods through the connector mechanism, reducing the effort and steps required for assembly and disassembly.
3Quantity of substance
If conventional racks are designed to be large, then storage capability is improved, but device size and storage space requirements worsen
Solution Approach 1:
The rack is segmented into collapsible supporting members that can be compacted when not in use. Each supporting member can be independently collapsed by pivoting the supporting rods, allowing the overall device volume to be significantly reduced while maintaining full storage capability when assembled.
Solution Approach 2:
When collapsed, the supporting rods are pivoted to nest within or alongside each other, with the holding rod serving as a central pivot point. This nesting arrangement allows the rack to occupy minimal storage space when collapsed while maintaining its full extended dimensions and storage capability when assembled.
4Ease of manufacture
If conventional racks are designed to be simple, then ease of manufacture is improved, but adaptability and configurability deteriorate
Solution Approach 1:
The connectors are designed as universal components that can connect different supporting rods in multiple configurations. The pivotal connection design allows the same connector to accommodate various rod positions and orientations, enabling the rack to be manufactured with standardized parts while achieving high configurability and adaptability for different storage needs.
Solution Approach 2:
The dynamic pivotal connections allow the rack structure to adapt to different configurations through simple rod movements. The holding rod mechanism enables the user to adjust the rack between collapsed and extended states, and potentially between different storage configurations, using the same basic connector design, thus maintaining manufacturing simplicity while achieving versatility.

AI summary
A collapsible rack is disclosed. In one embodiment, a collapsible rack has a first supporting member, a second supporting member, a first connecting member and a second connecting member. The first supporting member may include a first pair of supporting rods, a second pair of supporting rods and a first supporting fabric. The first pair of supporting rods are parallel and spaced with a predetermined distance, as well as the second pair supporting rods. The first pair of supporting rods and the second pair of supporting rods are connected to form a rectangular surface and the first supporting fabric is secured. The structure of the second supporting member is substantially identical to the first supporting member, and the first and second supporting members are parallel, spaced with a predetermined distance and connected by the first and second connecting members.
