Solution Overview

Problem

Existing hooks for elastic belts are prone to releasing and breaking during use, posing safety hazards to users due to inadequate connection mechanisms.

Innovation Solution

A double-safety anti-dropping and anti-fracture hook design featuring a main hook body with a tapered hole, notch, and arch-shaped second connecting hole, along with a connecting beam for a safety rope, which provides secondary locking and ensures the elastic belt is securely attached, preventing accidental release or breakage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the elastic belt is quickly connected with the hook by plugging, then the connection convenience is improved, but the reliability of preventing releasing and breakage deteriorates

Engineering Contradiction:
Improveconnection convenienceVSAvoidpreventing releasing and breakage
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The hook is divided into multiple functional components: a first connecting hole for initial connection, a second connecting hole for safety rope attachment, and a tapered hole for locking the elastic belt. This segmentation allows the hook to provide both quick connection and reliable retention through separate structural elements working together.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The safety rope is pre-installed through the second connecting hole and tied to form a knot before use. This preliminary preparation ensures that the secondary safety mechanism is already in place and functional, providing immediate protection against releasing or breakage without requiring additional actions during exercise.

Inventive Principle:
Principle #10Preliminary action

2Device complexity

If the hook structure is simplified for easy connection, then the device complexity is reduced, but the strength and anti-fracture capability deteriorate

Engineering Contradiction:
Improvehook structure simplicityVSAvoidanti-fracture capability
Core Design Contradiction:
Device complexityVSStrength

Solution Approach 1:

The hook incorporates localized structural features that enhance strength where needed: the arch-shaped second connecting hole provides structural reinforcement, the tapered hole creates a locking mechanism that prevents slippage, and the notched big end concentrates strength at critical connection points. These local quality enhancements maintain overall structural simplicity while providing robust anti-fracture capability.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The hook is made from high-strength alloy material that combines multiple properties: tensile strength to resist breaking, elasticity to absorb stress, and durability to prevent deformation. This composite material approach allows the simple hook structure to achieve superior strength and anti-fracture performance without increasing complexity.

Inventive Principle:
Principle #40Composite materials
