Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If oblique crosspieces are fixed to vertical uprights with a single fixing point, then the structure is simple to manufacture, but the versatility and adaptability of the frame structure is limited

Engineering Contradiction:
Improvesimplicity of fixationVSAvoidversatility of frame structure
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The side walls are segmented into multiple sections with through openings positioned at different heights, creating multiple discrete connection points along the vertical element. This segmentation allows the single continuous side wall to provide multiple separate fixation locations, resolving the contradiction between simple manufacture and high versatility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The vertical uprights are designed with multiple through openings in their side walls, enabling them to serve multiple functions: supporting oblique crosspieces at different positions, accommodating various connection configurations, and providing adaptability for different structural requirements. This multi-functionality directly addresses the versatility limitation.

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

2Ease of manufacture

If section bars have a fixed configuration with one constraint position, then the manufacturing process is simple, but the functionality and adaptability for different construction purposes are limited

Engineering Contradiction:
Improvesimplicity of section bar configurationVSAvoidfunctionality for different purposes
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The side walls are designed with through openings that enable angular displacement and rotation of the section bars relative to each other. This dynamic capability allows the rigid extruded profiles to accommodate various angles and positions, transforming a static fixed configuration into a dynamic adaptable structure while maintaining manufacturing simplicity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The design adds a dimensional degree of freedom by allowing angular displacement between connected section bars. The through openings enable rotation and tilting movements, adding angular freedom to the previously fixed linear configuration, thus expanding functionality without complicating the extruded profile manufacturing.

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

3Ease of operation

If the frame structure uses standard section bars with limited constraint positions, then the construction process is straightforward, but the customization and spatial optimization capabilities are reduced

Engineering Contradiction:
Improvestraightforward construction processVSAvoidcustomization capability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

By segmenting the side walls with multiple through openings at different heights and positions, the structure gains multiple discrete constraint points. This segmentation enables customized configurations and spatial optimizations while maintaining the straightforward extruded profile construction process, as the openings are simply positioned during the extrusion rather than requiring complex post-processing.

Inventive Principle:
Principle #1Segmentation
