Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the stacking assembly is made of the same material, then the manufacturing process is simplified, but different functional characteristics for different parts cannot be achieved

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

Solution Approach 1:

The stacking assembly is divided into multiple connecting members with different materials (plastic and metal) to achieve different functional characteristics for different parts while maintaining overall manufacturing simplicity through modular assembly

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different parts of the stacking assembly are assigned different materials based on their specific functional requirements - plastic for flexibility and metal for durability - allowing each component to have optimized local properties

Inventive Principle:
Principle #3Local quality

2Ease of operation

If plastic is used for connecting members, then flexibility and ease of assembly are improved, but strength and durability are reduced

Engineering Contradiction:
Improveflexibility and ease of assemblyVSAvoidstrength and durability
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The stacking assembly uses a composite structure combining plastic and metal connecting members, where plastic provides flexibility and ease of assembly while metal provides strength and durability, achieving a balance between conflicting requirements

Inventive Principle:
Principle #40Composite materials

3Strength

If metal is used for connecting members, then strength and durability are improved, but flexibility and ease of assembly are reduced

Engineering Contradiction:
Improvestrength and durabilityVSAvoidflexibility and ease of assembly
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The stacking assembly uses a composite structure combining plastic and metal connecting members, where metal provides strength and durability while plastic provides flexibility and ease of assembly, achieving a balance between conflicting requirements

Inventive Principle:
Principle #40Composite materials

AI summary

A stacking assembly and a stacking system are provided. The stacking assembly has an accommodating space. The stacking assembly includes a first connecting member and a second connecting member. The first connecting member is configured to form at least one of an upper surface of the stacking assembly and a lower surface of the stacking assembly. The second connecting member is connected to the first connecting member to form the accommodating space. A material of the first connecting member is different from a material of the second connecting member.
