Solution Overview

Problem

Users of kettle bells, dumbbells, and barbells need to purchase multiple weights of different sizes, as existing equipment does not allow for convenient adjustment or combination of weights, making it cumbersome to switch between exercises.

Innovation Solution

A combinable weight plate system with a limiting assembly and engaging assembly, allowing multiple weight plates to be detachably connected and easily assembled/disassembled, enabling adjustable weights for kettle bells, dumbbells, and barbells without the need for multiple equipment pieces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If users use traditional kettle bells, dumbbells, or barbells with fixed weights, then the equipment structure is simple, but users need to purchase multiple equipment pieces with different weights, increasing device complexity and storage requirements

Engineering Contradiction:

Improveweight adjustabilityVSAvoidequipment structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The weight plate is divided into multiple detachable segments (first weight plate, second weight plate, third weight plate) that can be independently connected and disconnected. Each segment has specific connection structures (connection holes, connection protrusions, connection grooves) that allow modular assembly, enabling users to adjust weights by combining different segments rather than requiring completely different equipment pieces.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The weight plate design serves multiple functions: it can be used as a single unit or combined with other weight plates to create different weight configurations. The same connection structures (engagement assemblies with fixing blocks and engaging blocks) work for both attaching weight plates to barbells and connecting weight plates to each other, making the design universally applicable for various fitness equipment types.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If users purchase multiple kettle bells, dumbbells, and barbells with different weights, then weight variety is achieved, but storage space requirements increase and user convenience decreases

Engineering Contradiction:

Improveweight varietyVSAvoiduser convenience

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The weight plate system transitions from static fixed-weight equipment to dynamic adjustable-weight equipment. The engagement assemblies allow weight plates to be easily connected and disconnected during workouts, enabling users to dynamically adjust weights between exercises without needing to store and swap multiple complete equipment pieces, significantly improving user convenience.

Inventive Principle:

Principle #15Dynamics

3Productivity

If traditional weight plates are used, then manufacturing is simple, but weight adjustment requires replacing entire equipment pieces, increasing time consumption

Engineering Contradiction:

Improveweight adjustment speedVSAvoidequipment swapping time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The connection structures (connection holes, connection protrusions, connection grooves) and engagement assemblies are pre-designed and pre-positioned on the weight plates during manufacturing. This preliminary preparation allows for rapid assembly and disassembly during workouts, as users only need to connect or disconnect individual weight plates rather than reconfigure entire equipment pieces, significantly reducing time consumption.

Inventive Principle:

Principle #10Preliminary action
