Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If traditional machine room layout is used, then pipeline layout becomes complicated and chaotic, but space requirement and pipeline resistance increase

Engineering Contradiction:
Improvepipeline layout complexityVSAvoidmachine room space requirement
Core Design Contradiction:
Device complexityVSArea of stationary object

Solution Approach 1:

The machine room layout is divided into standardized modular blocks representing different equipment and pipeline sections. Each block is a pre-designed unit that can be independently configured and assembled, transforming the chaotic continuous layout into organized discrete segments that reduce overall complexity and space requirements

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent creates a universal layout block library where standardized blocks can represent multiple equipment types and pipeline configurations. These universal blocks can be reused across different machine room designs, reducing the need for custom layouts and minimizing space requirements through standardized footprints

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

2Device complexity

If traditional machine room layout is used, then pipeline layout becomes complicated and chaotic, but energy consumption increases

Engineering Contradiction:
Improvepipeline layout complexityVSAvoidmachine room energy consumption
Core Design Contradiction:
Device complexityVSUse of energy by moving object

Solution Approach 1:

By segmenting the pipeline layout into standardized blocks, the system optimizes pipeline routing to reduce length and minimize crossings. This segmented approach allows for more efficient energy distribution and reduces energy losses associated with longer, more complex pipeline routes

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from two-dimensional floor plans to three-dimensional spatial arrangement through stacked layout blocks. This vertical dimensionality reduces horizontal pipeline length and minimizes crossings by utilizing multiple levels, thereby reducing energy consumption for fluid transport

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

3Loss of information

If traditional machine room layout is used, then spatial location relationships cannot be intuitively reflected, but adaptability is reduced

Engineering Contradiction:
Improvespatial relationship informationVSAvoidmachine room adaptability
Core Design Contradiction:
Loss of informationVSAdaptability or versatility

Solution Approach 1:

The layout blocks incorporate color coding and visual differentiation that intuitively indicate spatial relationships, equipment types, and pipeline connections. This visual encoding system allows operators to quickly understand spatial arrangements and relationships without detailed documentation, improving both information clarity and adaptability

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent uses standardized graphical representations and digital models that copy and simplify the physical layout into intuitive visual formats. These standardized copies can be easily interpreted and adapted to different scenarios, maintaining spatial relationship information while enhancing adaptability

Inventive Principle:
Principle #26Copying
