Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If foldable storage boxes are designed to be collapsible for space-saving, then they become easy to store and transport, but their structural strength and stability deteriorate, causing deformation and inability to hold items

Engineering Contradiction:

ImprovefoldabilityVSAvoidstructural strength

Core Design Contradiction:

Adaptability or versatilityVSStrength

Solution Approach 1:

The box frame is divided into multiple connection points along its edges, with reinforcing strips positioned at these segmented locations. This segmentation allows the frame to maintain flexibility for folding while adding localized strength where structural integrity is needed most, preventing deformation during use.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Reinforcing strips are applied locally at specific connection points rather than uniformly across the entire frame. This local quality approach strengthens critical areas that experience stress during folding and loading, while preserving the overall foldability and lightweight characteristics of the storage box.

Inventive Principle:

Principle #3Local quality

2Volume of stationary object

If the storage box is made larger to increase capacity, then more items can be stored, but the bottom wall panel becomes prone to falling off and deformation increases

Engineering Contradiction:

Improvestorage capacityVSAvoidbottom panel stability

Core Design Contradiction:

Volume of stationary objectVSReliability

Solution Approach 1:

Reinforcing strips are pre-installed at the connection points between the bottom wall panel and box frame before the box is assembled or loaded. This preliminary reinforcement ensures that even in larger boxes, the bottom panel maintains strong attachment and resists deformation under weight, preventing the panel from falling off during use.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If hinges and folding mechanisms are added to enable folding, then the box becomes collapsible for space-saving, but the device complexity increases

Engineering Contradiction:

ImprovecollapsibilityVSAvoidstructural complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The folding mechanism is segmented into discrete connection points with reinforcing strips at each joint. This segmentation allows the complex folding function to be achieved through multiple simple, standardized connection elements rather than a single complex mechanism, making the overall structure more manageable and manufacturable.

Inventive Principle:

Principle #1Segmentation

AI summary

A foldable storage box includes a box frame. The box frame and a bottom wall panel clamped at a bottom of the box frame form a storage space. The side walls of the box frame are provided with a plurality of fold hinges to fold the box frame. The bottom of the box frame is integrally formed with several support straps. The support straps are arranged on the outside of the bottom wall panel, and the support straps are engaged or mated with the bottom wall panel.
