Innovation Solution
A foldable storage rack design featuring side frames with guide grooves and slide shafts, connecting arms, and shelves that can be easily transitioned between unfolded and folded states without disassembly, incorporating locking devices and casters for convenience and space efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional storage rack uses non-detachable welding manner, then manufacturing strength is improved, but device complexity and transportation space increase
Solution Approach 1:
The storage rack is divided into multiple detachable modules including side frames, shelves, connecting arms, and slide shafts. Each module can be independently manufactured and assembled, replacing the conventional non-detachable welding structure. This segmentation allows for simplified manufacturing processes while maintaining structural integrity through the hinge connections and locking mechanisms.
Solution Approach 2:
The storage rack incorporates dynamic elements such as hinge connections between side frames and shelves, and slide shafts that allow the rack to transition between extended and folded states. This dynamic design enables the rack to adapt its configuration for different storage needs and transportation requirements, reducing overall device complexity compared to fixed welded structures.
2Stability of the object's composition
If conventional storage rack uses welding procedure, then structural stability is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The rack structure is segmented into modular components that can be manufactured separately using simpler processes and then assembled through hinge connections. This eliminates complex welding procedures while maintaining structural stability through the mechanical connection of side frames, shelves, and connecting arms.
Solution Approach 2:
Hinge connections and locking mechanisms serve as intermediary elements between the modular components. These intermediaries provide stable mechanical connections without requiring welding, allowing for easy assembly and disassembly while maintaining structural integrity during use.
3Volume of moving object
If conventional storage rack uses assembled/disassembled manner, then transportation space is reduced, but ease of operation deteriorates due to mounting difficulty and component loss
Solution Approach 1:
The storage rack is designed with segmented modular components that can be easily assembled and disassembled. The standardised hinge connections and locking mechanisms enable users to quickly assemble the rack without special tools or expertise, eliminating the mounting difficulties associated with conventional assembled/disassembled racks.
Solution Approach 2:
The connecting arms and slide shafts merge the functions of connection and guidance into a single integrated mechanism. This design reduces the number of separate components that need to be managed during assembly and disassembly, reducing the risk of component loss while maintaining ease of operation.
4Volume of moving object
If storage rack is designed for folded state, then transportation space is reduced, but manufacturing complexity increases
Solution Approach 1:
The storage rack incorporates dynamic hinge connections and slide shafts that enable smooth transition between folded and extended states. These dynamic elements are integrated into the basic modular structure, allowing the rack to fold compactly for transportation without significantly increasing manufacturing complexity beyond the initial modular design.

AI summary
A foldable storage rack, including side frames, connecting arms and shelves. When unfolded, the foldable storage rack can satisfy a user's storage needs, and when the foldable storage rack is being transported or idle, the side frames, the connecting arms and the shelves of the foldable storage rack are folded in an interlinked manner. The foldable storage rack in a folded state occupies a small space and is convenient for storage and transportation.
