Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional construction methods are used, then structural integrity and precision can be maintained, but construction time is excessively long (several months)

Engineering Contradiction:
Improveconstruction speedVSAvoidconstruction period
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent changes the fundamental construction parameter from manual/sequential assembly to automated/layer-by-layer deposition. The additive manufacturing system extrudes material continuously in controlled layers, transforming the construction process from discrete component assembly to continuous material deposition, thereby dramatically reducing construction time while maintaining precision through computer-controlled positioning.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent replaces traditional mechanical construction systems (cranes, manual labor, sequential assembly operations) with an automated additive manufacturing system. The gantry-based extrusion system uses computer-controlled motion systems to deposit material layer by layer, substituting heavy mechanical assembly operations with precise automated deposition, achieving both speed and structural integrity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of manufacture

If traditional construction methods with multiple skilled trades are used, then comprehensive construction quality can be ensured, but the process becomes complex and time-consuming

Engineering Contradiction:
Improveconstruction process simplicityVSAvoidnumber of skilled trades required
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The additive manufacturing system performs multiple construction functions that traditionally required different skilled trades (masonry, concrete work, structural assembly) through a single integrated machine. The extrusion system can deposit various materials (concrete, mortar, infill materials) and perform different construction tasks (wall construction, infill, detailing) using the same gantry system, eliminating the need for multiple specialized trades.

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

Solution Approach 2:

The patent merges multiple construction operations into a single continuous process. The extrusion system combines material deposition, layer formation, and structural construction in one integrated operation, rather than requiring separate steps for different trades. The system merges the functions of multiple specialized construction teams into a single automated process that deposits and forms structure in one continuous workflow.

Inventive Principle:
Principle #5Merging (Combining)
