Solution Overview

Problem

Existing reinforced concrete slabs are excessively heavy and lack interstitial spaces for installations or conduits, necessitating additional hollowed-out layers that increase their thickness and weight, compromising structural efficiency.

Innovation Solution

A modular hollowed-out plate with multidirectionally continuous holes formed by parallel flat strips and an intermediate lamellar structure, allowing for self-supporting spans and integrated channels for installations without additional thickness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If reinforced concrete slabs are used to achieve structural resistance and load-bearing capacity, then strength is improved, but weight increases excessively

Engineering Contradiction:

Improvestructural resistanceVSAvoidslab weight

Core Design Contradiction:

StrengthVSWeight of stationary object

Solution Approach 1:

The slab is segmented into a lattice structure with multidirectionally continuous holes, dividing the solid concrete mass into interconnected cellular elements that maintain structural integrity while reducing weight

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention employs a porous lattice structure with continuous holes throughout the slab, creating a lightweight material that maintains strength through its geometric configuration rather than material mass

Inventive Principle:

Principle #31Porous materials

2Adaptability or versatility

If additional hollowed-out layers are added to provide spaces for installations, then adaptability is improved, but thickness and weight increase

Engineering Contradiction:

Improveinstallation spacesVSAvoidslab thickness

Core Design Contradiction:

Adaptability or versatilityVSLength of stationary object

Solution Approach 1:

The structural lattice and installation spaces are merged into a single integrated system, where the holes serving as installation pathways are the same holes that provide weight reduction, eliminating the need for separate hollowed-out layers

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The lattice holes serve multiple functions simultaneously: reducing slab weight, providing thermal and acoustic insulation, and creating accessible interstitial spaces for installations and conduits throughout the slab structure

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

The invention relates to plate that comprises an upper strip (1), a lower strip (2), both of which are flat, and a multidirectionally folded, curved or undulate intermediate structure (3) arranged between the upper strip (1) and the lower strip (2), and which is joined to the upper (1) and lower (2) strips at contact zones or connection points (4) and (5), intermittently located and distributed, such that it defines at least two chambers, channels or hollow spaces, interstitial (6) and (7) and continuous, which extend throughout the plate in at least two different directions. This way, a lightweight plate is obtained that is structurally, acoustically and thermally resistant, easy to systematically manufacture or mount and can be efficiently used as an integral system for constructing slabs and similar, since the inner holes can also be used as integrated accessible channels for installations.
