Solution Overview

Problem

Existing formwork anchor systems in the construction industry face challenges in achieving regular anchor spacings and efficient operation, leading to increased labor costs and potential operational errors due to complex setup and alignment requirements.

Innovation Solution

A formwork anchor system featuring a ball section in a support component that allows the anchor to pivot, enabling compensation for deviations in anchor passage openings and ensuring load-bearing anchoring, tightness, and easy operation, with a locking mechanism using grooves and elastic fixing means for secure connection and reduced labor costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a formwork anchor system uses fixed alignment requirements for anchor passage openings, then anchoring precision is improved, but operational complexity and labor costs increase due to difficult alignment and setup

Engineering Contradiction:
Improveanchor spacing regularityVSAvoidsetup and alignment difficulty
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The support component includes a spherical section that allows the formwork anchor to pivot and adjust its orientation dynamically. This spherical joint enables the anchor to adapt to misalignments between opposing formwork elements, compensating for positioning errors without requiring precise pre-alignment during installation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The spherical section changes the orientation parameter of the anchor rod relative to the formwork element. By allowing pivoting motion, the system can accommodate variations in anchor passage opening positions and achieve proper anchoring despite deviations in the original positioning parameters.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If a formwork anchor system requires two-sided operation for secure connection, then connection reliability is improved, but productivity decreases due to increased labor requirements

Engineering Contradiction:
Improveconnection securityVSAvoiderection speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The spherical section and locking device combination enables the formwork anchor to be operated from one side only. The spherical joint automatically adjusts to accommodate misalignments, and the locking device secures the anchor rod in place, allowing the system to serve itself by eliminating the need for workers on the opposite side during installation.

Inventive Principle:
Principle #25Self-service

3Strength

If a formwork anchor system uses complex locking mechanisms, then anchoring strength is improved, but device complexity increases leading to harder operation

Engineering Contradiction:
Improveanchoring load bearing capacityVSAvoidlocking mechanism complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The locking device is divided into separate components: a locking element with grooves that engage with grooves on the anchor rod, and an elastic fixing element. This segmentation allows each component to perform its specific function independently, simplifying the overall mechanism while maintaining secure locking capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The locking element acts as an intermediary between the anchor rod and the formwork anchor receptacle. The grooves on the locking element engage with grooves on the anchor rod, providing a simple yet effective locking action that secures the anchor without requiring complex mechanisms.

Inventive Principle:
Principle #24Intermediary (Mediator)
