Solution Overview

Problem

The assembly of wall formwork in concrete construction is complex and time-consuming due to the need for precise alignment and absorption of tensile and compressive forces, which limits the efficiency of the anchor system.

Innovation Solution

The introduction of a grid dimension on the tie rod and the use of locking devices with a stop mechanism allows for quick and precise setting of wall thickness, enabling easy alignment and absorption of forces, with the anchor system comprising an anchor rod and two locking devices that can be easily assembled and disassembled.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional anchor systems are used without grid dimensions or stop mechanisms, then the assembly process requires complex alignment procedures, but the assembly time and operational complexity increase significantly

Engineering Contradiction:
Improvealignment precisionVSAvoidassembly time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-marking grid dimensions on the tie rod and pre-positioning stop mechanisms at specific locations. These preliminary markings and stops are prepared in advance on the anchor system components, enabling workers to quickly align formwork elements without complex measurement procedures during assembly, thus reducing assembly time while maintaining precision

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces grid dimension markings and stop mechanisms as intermediary elements between the tie rod and the formwork elements. These intermediaries provide visual and physical references that facilitate precise alignment without requiring complex measurement tools or procedures, effectively mediating the alignment process between components

Inventive Principle:
Principle #24Intermediary (Mediator)

2Strength

If traditional anchor systems without stop mechanisms are used, then the absorption of tensile and compressive forces is complicated, but the device complexity and alignment difficulty increase

Engineering Contradiction:
Improveforce absorption capabilityVSAvoidalignment complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The stop mechanism acts as an intermediary element that simplifies the force absorption process. By providing a predetermined stop position, it automatically ensures correct alignment and load distribution between tensile and compressive forces, eliminating the need for complex alignment procedures while maintaining full force absorption capability

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The stop mechanism enables the anchor system to self-align and self-regulate force distribution. When the formwork elements are assembled, the stop automatically positions the components to ensure proper load bearing, allowing the system to serve itself in achieving correct alignment and force absorption without external intervention or complex procedures

Inventive Principle:
Principle #25Self-service

3Measurement precision

If precise alignment mechanisms are added to the anchor system, then the alignment precision improves, but the device complexity increases

Engineering Contradiction:
Improvealignment precisionVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent uses preliminary action by pre-marking grid dimensions and pre-positioning stops on the tie rod during manufacturing. These preliminary features are integrated into the basic structure without adding complex adjustable mechanisms, achieving precise alignment through simple, predetermined geometric references that do not increase system complexity

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent applies local quality by adding alignment features (grid markings and stops) only at specific critical locations on the tie rod where alignment is needed, rather than making the entire system complex. The majority of the anchor system remains simple, with precision features localized to where they are most needed

Inventive Principle:
Principle #3Local quality

AI summary

The application relates to an anchoring system for wall formwork and a method for assembling the anchoring system: • the two wall formworks (1, 2, 3, 40) are set up opposite each other, • an anchor rod (4) with a grid dimension (21) is pushed through anchor rod bores in the two wall formworks (1, 2, 3, 40) such that the end of the anchor rod (4) not pushed through has the grid dimension (21), • the end of the anchor rod (4) pushed through is connected to a locking device (41) located on the back of one of the formworks (40), • the end of the anchor rod (4) not pushed through is connected to the locking device (5, 6, 7, 8, 13, 14, 15) provided here so that this connection is aligned with the selected grid dimension, • the locking device aligned with the grid dimension is attached to the adjacent wall formwork (1, 2, 3) connected.
