Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If existing cages use a plastic grid structure with bolts, then the cage can be assembled, but it is difficult to assemble and disassemble, and prone to deformation and loosening under pressure

Engineering Contradiction:
Improveease of assembly and disassemblyVSAvoidstructural stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The cage is divided into modular components (cage body, attachment blocks, support bars) that can be independently assembled and disassembled. The attachment blocks with connection holes and bulges create standardized interfaces between segments, enabling easy assembly while maintaining structural integrity through distributed connection points.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cage design incorporates adjustable and reconfigurable elements that allow the structure to adapt to different assembly configurations. The support bars and attachment blocks can be positioned and connected in various arrangements, providing both ease of assembly and structural stability under different loading conditions.

Inventive Principle:
Principle #15Dynamics

2Stability of the object's composition

If existing cages have limited space, then the structure is simpler, but the cage cannot ensure stability during horizontal unloading and vertical stacking

Engineering Contradiction:
Improvestructural stability during stackingVSAvoidcage structure complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The cage design incorporates vertical stacking capability through attachment blocks with connection holes and bulges that enable both horizontal and vertical connections. This multi-dimensional connection system allows cages to be stacked vertically while maintaining stability, transforming a two-dimensional planar structure into a three-dimensional stable configuration.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The cage combines different structural elements (plastic grid, metal support bars, attachment blocks with bulges) to create a composite structure that achieves both stability and manageable complexity. The support bars provide rigid reinforcement while the modular attachment blocks simplify the connection system.

Inventive Principle:
Principle #40Composite materials

3Strength

If the cage uses a simple structure, then it is easier to manufacture, but it is prone to deformation under long-term pressure

Engineering Contradiction:
Improveresistance to deformationVSAvoidmanufacturing simplicity
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The cage structure is segmented into standardized modules with attachment blocks featuring connection holes and bulges. This segmentation allows for simplified manufacturing of individual components while the assembled structure achieves high strength through distributed load paths and multiple connection points that resist deformation under pressure.

Inventive Principle:
Principle #1Segmentation
