Solution Overview

Problem

In construction, traditional timber formwork for concrete slab edges is inefficient due to material wastage, labor-intensive, and poses safety risks from nails, and existing solutions do not adequately address these issues.

Innovation Solution

A bracket system comprising interconnected members with a lug or protrusion engagement feature that securely attaches to formwork, providing improved strength and reducing material wastage and labor, featuring a mechanical linkage with adjustable components for versatile use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of substance

If traditional timber formwork is used, then material availability is ensured, but material wastage increases and labor requirements increase

Engineering Contradiction:
Improvematerial wastageVSAvoidlabor efficiency
Core Design Contradiction:
Loss of substanceVSProductivity

Solution Approach 1:

The bracket system is designed to be reusable across multiple formwork applications. The metal bracket with its standardized formation can be detached from one formwork panel and reattached to another, recovering the support function repeatedly rather than discarding timber brackets after single use. This directly reduces material wastage while maintaining productivity.

Inventive Principle:
Principle #34Discarding and recovering

Solution Approach 2:

The bracket design incorporates a standardized formation that can engage with multiple different formwork panels and configurations. The universal interface allows the same bracket to serve various supporting functions across different locations and applications, reducing the need for multiple specialized timber components and thereby reducing overall material wastage and labor.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If timber formwork is used, then ease of construction is maintained, but safety risks increase due to nails

Engineering Contradiction:
ImprovesafetyVSAvoidconstruction simplicity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The invention replaces the traditional timber-and-nails mechanical connection system with a metal bracket system that uses formation engagement (interlocking geometric shapes) rather than fasteners. This substitution eliminates nail-related safety hazards while maintaining ease of construction through the simple engage-disengage mechanism of the formation interface.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The dangerous element (nails) is completely extracted from the construction system. The bracket relies solely on the mechanical interlocking of formations without any penetrating fasteners, removing the safety hazard entirely while preserving construction simplicity through the straightforward engagement mechanism.

Inventive Principle:
Principle #2Taking out (Extraction)

3Adaptability or versatility

If fixed bracket design is used, then manufacturing simplicity is maintained, but adaptability to different formwork sizes is reduced

Engineering Contradiction:
Improveadjustability to formwork sizesVSAvoidbracket structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The bracket incorporates adjustable elements that allow modification of its geometry to suit different formwork panel sizes. Rather than a fixed rigid structure, the bracket can be dynamically adjusted in length or angle, providing adaptability while keeping the overall structural concept relatively simple and manufacturable.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The bracket is divided into modular segments or components that can be assembled in different configurations. This segmentation allows the same basic bracket design to adapt to various formwork sizes by simply reconfiguring the segments, maintaining manufacturing simplicity through standardized parts while achieving versatility.

Inventive Principle:
Principle #1Segmentation
