Solution Overview

Problem

Existing methods for securing structural strength in angle irons, such as using L-shape angle irons or welding struts, compromise on stiffness or material efficiency and quality, leading to uncertain integration and higher production costs.

Innovation Solution

A corner bracket with reinforcing ribs is designed, comprising two intersecting fixing plates with embossed ribs, forged in a single molding process, eliminating the need for filler material and reducing production time and costs while enhancing structural strength.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If welding struts are used to secure structural strength, then structural strength is improved, but manufacturing complexity and production time increase

Engineering Contradiction:

Improvestructural strengthVSAvoidmanufacturing complexity

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The patent combines multiple components (fixing plates and reinforcing ribs) into a single integrated corner bracket structure. The reinforcing ribs are formed as integral parts of the fixing plates through one-stage molding, eliminating the need for separate welding operations and filler materials while maintaining structural strength.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The reinforcing ribs are pre-formed as integral parts of the fixing plates during the molding process. This preliminary formation of strengthening features eliminates the need for subsequent welding operations, reducing manufacturing complexity and production time while ensuring structural integrity.

Inventive Principle:

Principle #10Preliminary action

2Ease of manufacture

If L-shape angle iron is used, then ease of manufacture is improved, but structural strength and stiffness deteriorate

Engineering Contradiction:

Improveease of manufactureVSAvoidstructural strength

Core Design Contradiction:

Ease of manufactureVSStrength

Solution Approach 1:

The patent applies local quality enhancement by adding reinforcing ribs at specific locations on the fixing plates. These ribs are strategically positioned to provide localized strengthening where structural demands are highest, while maintaining the overall simplicity of the angle iron form factor.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The corner bracket uses a composite structure combining flat fixing plates with three-dimensional reinforcing ribs. This composite geometry integrates the simplicity of sheet metal construction with the structural benefits of ribbed reinforcement, achieving both ease of manufacture and high strength.

Inventive Principle:

Principle #40Composite materials
