Solution Overview

Problem

Conventional weighted vests have complex structures that make them difficult to clean thoroughly, reduce comfort, and require replacement of the entire vest when parts wear out, lacking durability and practicality for long-term use.

Innovation Solution

A weighted vest designed with separable front and back piece bodies connected by a reinforcing connection element using metal wires, allowing easy separation and reconnection, and featuring hook-and-loop fasteners for enhanced durability and ease of cleaning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the weighted vest uses a complicated structure with pockets and adjustable parts to fit user body shape, then the vest can hold weights and adapt to different users, but the vest becomes difficult to clean thoroughly and less convenient to don and doff

Engineering Contradiction:

Improveadaptability to different usersVSAvoidease of cleaning

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The weighted vest is divided into separate front and back piece bodies that can be detached from each other. This segmentation allows the front and back pieces to be washed separately, making cleaning easier while maintaining the adaptability features like pockets and adjustable straps on each piece.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If the weighted vest uses a complicated structure with multiple parts, then the vest can be adjusted to fit different users, but the entire vest has to be replaced when any part wears out

Engineering Contradiction:

Improveadjustability to fit userVSAvoiddurability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The weighted vest is segmented into detachable front and back piece bodies connected by a reinforcing connection element. When one piece wears out, only that specific piece needs to be replaced rather than the entire vest, improving reliability while maintaining adjustability features.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The design allows individual pieces (front or back) to be discarded when worn and replaced independently, while the other piece continues to be used. This extends the overall lifespan of the weighted vest system.

Inventive Principle:

Principle #34Discarding and recovering

3Ease of manufacture

If the weighted vest uses conventional connection methods, then the vest can be assembled, but the connection is not durable enough for long-term use

Engineering Contradiction:

Improveease of assemblyVSAvoidconnection durability

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The reinforcing connection element combines metal wires with hook-and-loop fasteners to create a composite connection system. The metal wires provide strong mechanical tension resistance while the hook-and-loop fasteners enable easy attachment and detachment, achieving both durability and ease of assembly.

Inventive Principle:

Principle #40Composite materials
