Solution Overview

Problem

Existing prefabricated walls with integrated formwork pose safety risks during handling due to the need for operators to work at height and the irretrievable loss of connection means, and complex construction requirements, including the use of sophisticated and expensive technology for removal.

Innovation Solution

A prefabricated wall design with removable receiving means that are accessible from the exterior, featuring reversible fixing mechanisms and actuating means, allowing for safe handling and subsequent removal and reuse of connection means without the need for complex orientation or expensive technology.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If connection means are introduced inside the internal volume of the wall to be embedded in concrete cast in place, then the wall can be handled, but operators must work at height which poses safety problems and the connection means is irretrievably lost

Engineering Contradiction:
Improvehandling safetyVSAvoidoperator safety risk and material loss
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The receiving means is extracted from the internal volume of the wall and made accessible from the exterior side. This allows the connection means to be introduced and secured without requiring operators to work at height inside the wall, thereby eliminating the safety risk while preventing loss of connection means through reversible fixing

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The receiving means is designed with reversible fixing to the plates, allowing it to be removed after handling is complete. This enables the recovery and potential reuse of both the receiving means and the connection means, eliminating the irreversible loss that occurs with traditional embedding methods

Inventive Principle:
Principle #34Discarding and recovering

2Reliability

If a pivoting body with movable pin is used for receiving connection means, then the wall can be handled safely, but the construction becomes complex and expensive technology is required for removal

Engineering Contradiction:
Improvehandling safetyVSAvoidconstruction complexity and cost
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The receiving means is divided into separate components: the receiving means itself and the fixing means. This segmentation allows for simpler, independent design and manufacturing of each component, reducing overall complexity while maintaining safe handling through the reversible fixing mechanism

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The reversible fixing mechanism is designed to be simple and cost-effective, replacing the need for expensive electromagnetic pulse systems or complex mechanical release mechanisms. The fixing means can be easily removed after use without requiring sophisticated technology

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Stability of the object's composition

If receiving means are embedded inside the plates of the wall, then the wall structure is maintained, but the receiving means is not accessible for removal and connection means cannot be recovered

Engineering Contradiction:
Improvewall structure integrityVSAvoidaccessibility for removal and recovery
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

Instead of fully embedding the receiving means inside the plates, the design uses partial embedding with the fixing means accessible from the exterior. This partial action maintains sufficient structural integrity while enabling accessibility for removal and recovery of connection means

Inventive Principle:
Principle #16Partial or excessive action

AI summary

The invention relates to a wall with integrated formwork (1) comprising: - two plates (2; 2') made of a hydraulic mixture and positioned at a determined distance from each other (2; 2') so as to define an internal volume (3) in the wall (1); - a plurality of means for connecting the two plates (2; 2'); - at least one means for connecting the wall (1) to a handling device; - at least one receiving means (6) for such a connecting means (5), such receiving means (6) being removable, engaged inside at least a part of each of the two plates (2; 2') of the wall (1), and extending through the internal volume (3) of the wall (1); - means for reversibly fixing (7) the receiving means (6) to at least one of the plates (2; 2') of the wall (1); This wall (1) is characterized in that the receiving means (6): - open out or are accessible from an outside side (20) of at least one of these plates (2; 2');- include actuating means (9) for actuating this or these receiving means (6), this against the fixing means (7), these actuating means (9) being accessible from the outside side (20) of at least one of the plates (2; 2').;
