Pet Cage Swivel Hook Connecting Structure

Solution Overview

Problem

Traditional pet cages have a complex structure with a small included angle between lateral parts, leading to increased production costs, assembly difficulties, and potential harm to pets due to sharp edges.

Innovation Solution

A pet cage design featuring a connecting structure with swivel hooks on vertical rods that encircle horizontal rods, allowing for a simpler assembly process and reduced material costs, while ensuring smooth rotation and safety by forming an angle between 80° and 100°, and a manufacturing device with sliding tables and hook modeling platforms to bend vertical rods into swivel hooks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the included angle between returning section and vertical rod is made small to allow horizontal rod to pass through, then the connecting structure can be formed, but the returning section must have relatively long length which increases production cost

Engineering Contradiction:

Improveease of assemblyVSAvoidlength of vertical rod

Core Design Contradiction:

Ease of manufactureVSQuantity of substance

Solution Approach 1:

The patent applies curvature by transforming the straight returning section into a bent shape with specific geometric characteristics. The returning section is designed to bend at a specific angle (80°-100°) rather than forming a sharp small angle, creating a curved path that allows the horizontal rod to pass through while reducing the overall length of the vertical rod needed.

Inventive Principle:

Principle #14Spheroidality (Curvature)

2Ease of manufacture

If the included angle between returning section and vertical rod is small, then the connecting structure can be formed, but the space formed is not a round hole which increases assembly difficulty

Engineering Contradiction:

Improveease of assemblyVSAvoidsmooth rotation

Core Design Contradiction:

Ease of manufactureVSEase of operation

Solution Approach 1:

The patent applies curvature by transforming the straight returning section into a bent shape with specific geometric characteristics. The returning section is designed to bend at a specific angle (80°-100°) rather than forming a sharp small angle, creating a curved path that allows the horizontal rod to pass through while reducing the overall length of the vertical rod needed.

Inventive Principle:

Principle #14Spheroidality (Curvature)

Solution Approach 2:

The patent changes the geometric parameters of the returning section, specifically the included angle, from a small angle to an optimized range of 80°-100°. This parameter change creates a more favorable geometry that enables smooth rotation while maintaining the connecting function.

Inventive Principle:

Principle #35Parameter changes

3Ease of manufacture

If the returning section is used to connect lateral parts, then the cage structure can be formed, but the end of the returning section may hurt pets

Engineering Contradiction:

Improveease of assemblyVSAvoidsafety for pets

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent applies curvature by transforming the straight returning section into a bent shape with specific geometric characteristics. The returning section is designed to bend at a specific angle (80°-100°) rather than forming a sharp small angle, creating a curved path that allows the horizontal rod to pass through while reducing the overall length of the vertical rod needed.

Inventive Principle:

Principle #14Spheroidality (Curvature)

Solution Approach 2:

The patent converts the potentially harmful sharp end of the returning section into a beneficial rounded shape. By designing the returning section to bend at an optimized angle, the end becomes naturally rounded, transforming a safety hazard into a safe, pet-friendly structure.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)
