Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional reinforced concrete floor structures are used, then construction is straightforward, but design flexibility and adaptability to various foundations are limited

Engineering Contradiction:

Improvedesign flexibilityVSAvoidstructure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The reinforcement structure is divided into a triangular circumferential beam and multiple central ribs that extend from the center to the beam. This segmentation allows the structure to be manufactured in parts and assembled flexibly to adapt to different foundation conditions and architectural requirements while maintaining structural integrity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent employs a triangular circumferential beam with central ribs positioned asymmetrically to optimize load distribution and structural performance. The asymmetric triangular geometry provides enhanced adaptability to various foundation types and building configurations compared to conventional symmetric rectangular slabs.

Inventive Principle:

Principle #4Asymmetry

2Loss of substance

If conventional rectangular concrete slabs are used, then manufacturing is simple, but material waste increases and thermal insulation decreases

Engineering Contradiction:

Improvematerial wasteVSAvoidprefabrication complexity

Core Design Contradiction:

Loss of substanceVSEase of manufacture

Solution Approach 1:

The reinforcement structure including the triangular circumferential beam and central ribs is prefabricated in a controlled factory environment before concrete pouring. This preliminary fabrication ensures precise dimensional accuracy, minimizes material waste through optimized cutting and assembly, and allows for quality control while simplifying on-site installation.

Inventive Principle:

Principle #10Preliminary action

3Productivity

If standard reinforcement structures are used, then construction is straightforward, but load distribution efficiency is insufficient

Engineering Contradiction:

Improveload distribution efficiencyVSAvoidreinforcement structure complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The central ribs are strategically positioned to provide localized reinforcement in areas of high stress concentration, while the triangular circumferential beam provides overall structural stability. This local quality enhancement optimizes load distribution efficiency by concentrating reinforcement where needed rather than uniformly throughout the entire slab.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The addition of vertical central ribs extending from the center to the circumferential beam creates a three-dimensional reinforcement architecture. This dimensional enhancement improves load distribution by transferring loads through multiple pathways (radially through ribs and circumferentially through the beam) rather than relying solely on planar reinforcement.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
