Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing systems for assembling and disassembling wall formworks in concrete construction are cumbersome and require separate handling and detachment of coupling devices, which complicates the process and increases the risk of errors and injuries.
Innovation Solution
A detacheable and mechanically coupled coupling device that can be securely attached to the wall formwork without tools, allowing for flexible positioning and easy assembly/disassembly by incorporating a rod-like element with a broadened area for stability and a wedge for force transmission, enabling the device to remain attached during use and reducing the need for separate handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the coupling device is detached from the wall formwork for assembling or disassembling, then the coupling device can be repositioned or stored, but separate handling and detachment operations are required which complicates the process and increases the risk of errors and injuries
Solution Approach 1:
The coupling device is permanently attached to the wall formwork by integrating it into the formwork structure. The coupling device includes a rod that is fixed to the formwork, combining the coupling function with the formwork structure itself. This eliminates the need for separate detachment operations while maintaining the ability to couple and decouple wall formworks during assembly and disassembly processes.
2Ease of operation
If the coupling device is permanently attached to the wall formwork, then handling and operation is simplified, but the coupling device cannot be easily repositioned or stored
Solution Approach 1:
The coupling device is designed with dynamic characteristics that allow it to remain attached to the wall formwork during normal operation while enabling easy coupling and decoupling of wall formworks. The rod and clamp structure provides stable attachment during use but allows controlled separation when needed for assembly or disassembly operations.
3Adaptability or versatility
If traditional coupling devices are used requiring separate handling, then repositioning is possible, but the process is cumbersome and increases the risk of errors and injuries
Solution Approach 1:
The coupling device is integrated into the wall formwork structure through permanent attachment of the rod to the formwork. This merging of functions eliminates the need for separate handling operations, reduces the risk of errors and injuries associated with manual manipulation, while maintaining the flexibility to couple and decouple wall formworks during construction operations.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution simplifies the assembly and disassembly of wall formworks by allowing the coupling device to remain attached, reducing handling risks, and facilitating faster reconfiguration without the need for tools, while ensuring stability and secure coupling of the formworks.
Implementation Method 1
A wedge or the like is provided to displace both of the clamps for the coupling of two wall formworks
Implementation Method 2
The rod (4) comprises a broadened area (5), preferably a broadened end, which prevents the rod from being able to be passed through a hole (3) of a supporting element (1 or 2)

AI summary
According to the invention a wall formwork (1, 2) for the production walls consisting of concrete having a coupling device (4, 10), by means of which the wall formwork (1, 2) may be coupled to another wall formwork which is arranged adjacent or above is provided. The coupling device (4, 10) is - preferably detacheably - coupled to the wall formwork (1, 2) and is especially coupled to a supporting element (2) of the wall formwork (1, 2). By "coupled" it is meant that the coupling device (4, 10) may even kept coupled to the wall formwork (1, 2) when the coupling device (4, 10) will not be used for coupling the wall formwork (1, 2) to another wall formwork. By way of coupling between the coupling device (4, 10) and the wall formwork (1, 2), during installation, a coupling device (4, 10) will immediately be available, if the wall formwork (1, 2) is to be coupled to another wall formwork by the coupling device (4, 10). By this, assembling will be promoted. Also realization of disassembling may be promoted, since the coupling device (4, 10) does not have to be deposited nor handled separately. For disassembling detachment of the coupling device (4, 10) from the wall formwork (1, 2) which is arranged adjacent or above will be sufficient.
