Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the stacking assembly is made of the same material throughout, then the manufacturing process is simplified, but it becomes difficult to achieve different functional characteristics for different parts

Engineering Contradiction:
Improvemanufacturing process simplicityVSAvoidfunctional characteristics diversity
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The stacking assembly is divided into multiple components (first connecting member, second connecting member, third connecting member) that can be made from different materials. This segmentation allows each part to be optimized for its specific function while maintaining overall manufacturing efficiency through modular construction.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different parts of the stacking assembly are made from materials with locally optimized properties - for example, metal for structural strength in load-bearing connections, plastic for lightweight body sections, and wood for aesthetic or specific functional requirements. This enables each region to have the appropriate material properties for its intended function.

Inventive Principle:
Principle #3Local quality

2Adaptability or versatility

If different materials are used for different connecting members, then different functional characteristics can be achieved, but the manufacturing complexity increases

Engineering Contradiction:
Improvefunctional characteristics diversityVSAvoidmanufacturing process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The stacking members are designed with universal connection interfaces and standardized geometries that work across different material types. This allows metal, plastic, and wood components to be assembled together using the same connection mechanisms, reducing manufacturing complexity despite material diversity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The stacking assembly employs composite construction where different materials are combined in a coordinated manner - metal frames with plastic panels, or wooden bodies with metal reinforcement. This composite approach leverages the advantages of each material while maintaining manufacturing efficiency through integrated design.

Inventive Principle:
Principle #40Composite materials

3Strength

If metal is used for the second connecting member, then structural strength and safety are improved, but the weight increases

Engineering Contradiction:
Improvestructural strengthVSAvoidassembly weight
Core Design Contradiction:
StrengthVSWeight of moving object

Solution Approach 1:

Metal material is applied locally only where high strength is required - specifically in the second connecting member that provides structural support and safety functions. Other non-critical parts are made from lighter materials like plastic or wood, optimizing the overall weight-to-strength ratio of the assembly.

Inventive Principle:
Principle #3Local quality
