Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If welded structures are used for base structure, then mechanical strength is improved, but assembly difficulty and transportation difficulty increase due to requiring specialized labor and inability to dismantle

Engineering Contradiction:
Improvemechanical strengthVSAvoidassembly ease
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The base structure is divided into modular components (vertical profiles, horizontal profiles, coupling elements) that can be assembled and disassembled independently. Each module contains integrated coupling elements that simplify connection without requiring welding operations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The coupling elements are merged with the vertical profiles to form integrated structural columns. This combination provides both the mechanical strength of welded connections and the ease of modular assembly, as the coupling elements are pre-attached to the profiles.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If modular assembly of metal profiles is used, then assembly ease and transportation are improved, but manufacturing cost increases due to use of expensive Zamak alloys for corner connections

Engineering Contradiction:
Improveassembly easeVSAvoidmanufacturing cost
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The invention replaces expensive Zamak alloy corner connections with simpler, cheaper coupling elements made from standard metal profiles. These coupling elements maintain the modular assembly advantage while significantly reducing material costs.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The invention changes the material parameter from expensive Zamak alloy to more economical metal profiles with integrated coupling elements. This parameter change maintains the modular assembly benefits while reducing manufacturing costs.

Inventive Principle:
Principle #35Parameter changes

3Manufacturing precision

If skilled labor and appropriate equipment are used for correct perpendicular assembly, then assembly precision is improved, but productivity decreases due to daunting assembly task and high costs

Engineering Contradiction:
Improveperpendicular assembly precisionVSAvoidassembly productivity
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The coupling elements are pre-attached to the vertical profiles during manufacturing, creating pre-assembled structural columns. This preliminary action ensures correct perpendicular alignment is built-in, eliminating the need for skilled labor to achieve precise assembly during final installation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The coupling elements are designed to self-align and self-position the horizontal profiles perpendicular to the vertical profiles during assembly. This self-service mechanism eliminates the need for specialized equipment and skilled labor to ensure perpendicular assembly precision.

Inventive Principle:
Principle #25Self-service
