Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If beams are placed horizontally on top of each other to form walls (log-house-type construction), then the structure can be assembled using simple methods, but the construction time increases significantly and heavy machinery is required

Engineering Contradiction:

Improveassembly method simplicityVSAvoidconstruction speed

Core Design Contradiction:

Ease of manufactureVSProductivity

Solution Approach 1:

The patent inverts the conventional horizontal log-house construction method by using vertical stacking of beam elements. Instead of placing beams horizontally one on top of another, the invention uses vertical beam elements that are stacked and connected through insertion holes and fastening elements, fundamentally changing the construction approach to achieve both simplicity and speed.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The wall structure is segmented into discrete beam elements with standardized dimensions and connection features. Each beam element contains insertion holes and fastening elements that enable modular assembly, allowing rapid construction without heavy machinery while maintaining structural integrity through the segmented modular design.

Inventive Principle:

Principle #1Segmentation

2Stability of the object's composition

If traditional horizontal beam assembly is used, then structural stability can be achieved, but the construction process becomes time-consuming and requires heavy machinery

Engineering Contradiction:

Improvestructural stabilityVSAvoidconstruction time

Core Design Contradiction:

Stability of the object's compositionVSLoss of time

Solution Approach 1:

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The beam elements are pre-manufactured with standardized insertion holes and fastening elements already integrated into their structure. This preliminary preparation of connection features allows for rapid on-site assembly without requiring complex field operations or heavy machinery, significantly reducing construction time while ensuring structural stability.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If prefabricated concrete elements are used for underground structures or protective structures, then the structure can serve multiple purposes, but the construction method becomes complex and time-consuming

Engineering Contradiction:

Improvestructure multi-purpose useVSAvoidconstruction system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The beam elements are designed as universal modular components that can be used for multiple purposes including walls, underground structures, and protective structures. The standardized dimensions, insertion holes, and fastening elements allow the same basic element type to serve different structural functions, reducing the need for specialized components and simplifying the overall construction system.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The structure is divided into standardized beam element segments that can be easily assembled and configured for different applications. This segmentation allows the same modular elements to be adapted for various purposes such as underground construction or protective structures without requiring complex specialized components, thereby reducing construction system complexity while maintaining versatility.

Inventive Principle:

Principle #1Segmentation

AI summary

The corresponding structure of the invention is made from a set of prefabricated concrete elements. The concrete elements are variously sized rectangular prisms, long and narrow beams. The concrete elements serve different purposes: roof end and continuation elements are used to create roofs or ceilings, floor end and floor continuation elements are used to form floors or foundations, wall corner and wall continuation elements are used to construct walls. The entire structure is assembled solely from prefabricated concrete elements, and the construction does not require heavy machinery.
