Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional storage cabinets are designed with fixed structures to meet specific storage requirements, then storage functionality is improved, but space occupation increases and versatility decreases

Engineering Contradiction:
ImproveversatilityVSAvoidspace occupation
Core Design Contradiction:
Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The storage cabinet employs foldable side plates connected via pivot parts, transforming the fixed structure into a dynamic one that can switch between expanded storage mode and collapsed storage mode. This dynamic structure allows the cabinet to adapt to different space requirements while maintaining storage functionality

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The cabinet is divided into modular components including frame, back plate, folding side plates, bottom plate, and top plate, each connected through pivot parts. This segmentation enables independent movement and folding of each component, achieving both versatility and reduced space occupation when collapsed

Inventive Principle:
Principle #1Segmentation

2Volume of stationary object

If storage cabinets are designed to be compact for easy storage, then space efficiency is improved, but stacking capability and storage capacity are reduced

Engineering Contradiction:
Improvespace efficiencyVSAvoidstorage capacity
Core Design Contradiction:
Volume of stationary objectVSProductivity

Solution Approach 1:

The foldable side plates are designed to nest within the frame structure when collapsed, with the bottom plate and top plate folding inward. This nesting arrangement maximizes compactness while maintaining the ability to expand to full storage capacity when needed

Inventive Principle:
Principle #7Nested doll (Nesting)

3Volume of stationary object

If folding mechanisms are added to enable collapsible storage, then space efficiency is improved, but device complexity increases

Engineering Contradiction:
Improvespace efficiencyVSAvoidstructural complexity
Core Design Contradiction:
Volume of stationary objectVSDevice complexity

Solution Approach 1:

Multiple pivot connections are merged into a unified folding system where the frame, back plate, side plates, bottom plate, and top plate all connect through pivot parts. This merging of connection mechanisms simplifies the overall structure compared to using separate hinges for each component

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A folding storage cabinet is provided. The folding storage cabinet includes a back plate, two folding side plates, a frame, a bottom plate, and a top plate. Left and right sides of the back plate are respectively pivoted with one side of each of the two folding side plates, and the other side of each of the two folding side plates are pivoted with two sides of the frame. The folding side plates are capable of being bent to folded, such that the back plate may be close to the frame after the two folding side plates are folded, and the top plate and the bottom plate are respectively pivoted with the top portion and bottom portion of the back plate. The top plate and the bottom plate may be opened and closed relative to the back plate.
