Solution Overview

Problem

Existing thermally insulating concrete blocks fail to provide adequate structural strength and continuity of longitudinal reinforcement while maintaining effective thermal insulation, often resulting in compromised performance due to horizontal deformation, high material costs, and inefficient heat transfer pathways.

Innovation Solution

The design incorporates strategically positioned thermally insulating material sections within cavities to lengthen the shortest path through the block material, reducing heat transfer while ensuring structural stability through connections between the front and back faces, and includes through-holes for rebar reinforcement to maintain structural integrity and reduce thermal bridges.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If insulating panels are placed in the mold before filling with mortar, then thermal insulation properties are improved, but the block is subject to horizontal deformation and compression under great forces and pressures

Engineering Contradiction:
Improvethermal insulationVSAvoidresistance to horizontal deformation
Core Design Contradiction:
Loss of energyVSStrength

Solution Approach 1:

The block is divided into multiple cavities separated by internal walls made of mortar. These internal walls segment the insulating material into distinct sections, preventing horizontal deformation while maintaining thermal insulation. The segmentation allows the structure to withstand great forces and pressures without compromising the insulating panels.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different parts of the block have different properties: the internal walls and connecting elements are made of strong mortar material to provide structural support and resistance to deformation, while the cavities are filled with insulating material to provide thermal insulation. This local differentiation of material properties resolves the contradiction between strength and insulation.

Inventive Principle:
Principle #3Local quality

2Strength

If the block is made thicker to provide enough strength for structural support, then strength is improved, but building space is reduced

Engineering Contradiction:
Improvestructural support strengthVSAvoidbuilding space
Core Design Contradiction:
StrengthVSVolume of moving object

Solution Approach 1:

The block combines mortar material and insulating material in a composite structure. The mortar provides structural strength and load-bearing capacity, while the insulating material provides thermal insulation. This composite approach allows the block to achieve sufficient structural strength without increasing overall thickness, thereby preserving building space.

Inventive Principle:
Principle #40Composite materials

3Stability of the object's composition

If rebar runs through the insulating material, then continuity of longitudinal reinforcement is achieved, but the insulating material is easily damaged

Engineering Contradiction:
Improvecontinuity of longitudinal reinforcementVSAvoidintegrity of insulating material
Core Design Contradiction:
Stability of the object's compositionVSReliability

Solution Approach 1:

The rebar is extracted from the insulating material and placed only within the mortar portions of the block. The mortar sections serve as conduits for the reinforcement bars, allowing continuous longitudinal reinforcement without compromising the insulating material. This separation protects the insulating material from damage while maintaining structural continuity.

Inventive Principle:
Principle #2Taking out (Extraction)

4Stability of the object's composition

If an inner layer of mortar is added to provide a through-hole for rebar, then rebar continuity is achieved, but the block takes more space

Engineering Contradiction:
Improverebar continuityVSAvoidblock space
Core Design Contradiction:
Stability of the object's compositionVSVolume of moving object

Solution Approach 1:

The internal walls and connecting elements made of mortar serve multiple functions: they provide structural support, separate the cavities for thermal insulation, and simultaneously serve as conduits for rebar placement. This multi-functionality achieves rebar continuity without requiring additional space beyond the block's existing structure.

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

5Loss of energy

If webbing with thin walls is used to define empty inner cavities, then insulating properties are improved, but the block height is limited due to viscosity problems during filling

Engineering Contradiction:
Improvethermal insulationVSAvoidblock height
Core Design Contradiction:
Loss of energyVSLength of moving object

Solution Approach 1:

The formwork is designed with pre-positioned internal walls and cavity definitions before the mortar is poured. This preliminary structuring of the formwork allows the mortar to be poured in a controlled manner, ensuring proper filling of cavities and correct positioning of insulating material without viscosity-related problems, thereby enabling greater block heights.

Inventive Principle:
Principle #10Preliminary action
