Solution Overview

Problem

Walls with integrated formwork, particularly those with an insulating second skin, face damage during handling and installation due to stress exerted by connectors, leading to reduced usable interior space and rigidity issues.

Innovation Solution

A wall design featuring a first skin of hydraulic material and a second skin made of insulating material with a plurality of blocks and panels, where the blocks contain receptacles for connection means, and a second plate attached to the first plate for increased rigidity and resistance, allowing for effective anchoring and insulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If connectors are simply engaged through the second insulating skin, then the wall can be assembled, but the insulating skin suffers damage during handling and filling operations

Engineering Contradiction:
Improveconnector installationVSAvoidinsulating skin integrity
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

Receptacles are pre-formed within the insulating material before the insulating skin is fully assembled. These receptacles provide predetermined, protected pathways for connector engagement, eliminating the need to pierce or damage the insulating skin during later handling and filling operations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The receptacles act as intermediary structures between the connectors and the insulating skin. Instead of connectors directly engaging through the insulating skin (which causes damage), the receptacles mediate this interaction by providing a dedicated, protected space for connector placement and engagement.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Strength

If the second insulating skin is made with significant thickness to meet rigidity requirements, then the wall can withstand handling and filling operations, but the usable interior surface area is reduced

Engineering Contradiction:
Improvesecond skin rigidityVSAvoidusable interior surface
Core Design Contradiction:
StrengthVSArea of stationary object

Solution Approach 1:

The insulating skin is segmented into multiple sections or layers, with receptacles strategically positioned within these segments. This segmentation allows the insulating material to be distributed more efficiently, providing necessary rigidity through structural arrangement rather than simply increasing overall thickness, thereby preserving interior surface area.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The insulating skin incorporates composite construction combining insulating material with embedded receptacles and connection elements. This composite structure provides enhanced rigidity and mechanical strength without requiring a uniform increase in thickness throughout the entire insulating skin, thus maintaining maximum usable interior surface area.

Inventive Principle:
Principle #40Composite materials

3Stability of the object's composition

If connectors are embedded in traversing manner through the insulating skin, then connection between skins is achieved, but damage occurs to the insulating skin during handling

Engineering Contradiction:
Improveskin connectionVSAvoiddamage to insulating skin
Core Design Contradiction:
Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

Receptacles are pre-formed within the insulating material before assembly, creating predetermined pathways and engagement points for connectors. This preliminary action eliminates the need for connectors to traverse through the insulating skin in a way that causes damage, as the receptacles provide protected, designated spaces for connector placement.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The receptacles serve as intermediary structures that mediate between the connectors and the insulating skin. Instead of connectors directly traversing through the insulating skin (causing damage), the receptacles provide a protected interface that maintains skin integrity while enabling stable connection between skins.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The wall (1) has connection units (8) i.e. rod shaped connector, for connecting two skins (2, 3). The skin (2) is made of hardened material (7) e.g. concrete. The skin (3) includes an insulating plate (31) constituted by blocks (311) and insulating panels (312). The panels and blocks are arranged in a juxtaposed manner, and are interchanged within the plate. The skin (3) includes an insulating plate (32) connected on a surface (6') of the plate (31) opposite to a surface (6) at which a receptacle (5) opens. The blocks include a longiform panel element made of wood/extruded synthetic material.
