Solution Overview

Problem

Existing weight training systems require multiple specialized weight machines, which are costly and occupy significant space, and weight plates lack versatility for varied exercises without additional equipment.

Innovation Solution

A weight training system that utilizes a weight rack, weight plates, and adjustable arm assemblies with pivot blocks and modular attachments, allowing for pivoting and adjustable positioning of weight plates to accommodate different exercises and user preferences.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple specialized weight machines are used to provide various weight training exercises, then exercise versatility is improved, but space occupation and cost increase

Engineering Contradiction:

Improveexercise versatilityVSAvoidspace occupation

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent applies universality by designing a single weight rack system that can perform multiple weight training exercises through adjustable arm assemblies. The system allows users to configure different arm positions, weight plate locations, and exercise configurations, enabling one piece of equipment to replace multiple specialized machines while maintaining exercise versatility

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent applies segmentation by dividing the weight training system into modular components: a central weight rack, multiple independent arm assemblies, adjustable weight plates, and configurable attachments. This segmentation allows each component to be independently positioned and configured for different exercises, providing versatility without requiring multiple complete machine systems

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If built-in weights are increased in weight machines to provide higher resistance, then weight training capability is improved, but machine weight increases reducing mobility

Engineering Contradiction:

Improveweight training capabilityVSAvoidmachine weight

Core Design Contradiction:

Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The patent applies dynamics by using adjustable and removable weight plates instead of fixed built-in weights. Users can dynamically change the weight configuration by adding or removing plates from the weight rack, allowing weight training capability to be adjusted without permanently increasing the machine's base weight, thereby maintaining mobility

Inventive Principle:

Principle #15Dynamics

3Weight of moving object

If weight plates are used instead of built-in weights to reduce machine weight, then mobility is improved, but exercise versatility deteriorates

Engineering Contradiction:

Improvemachine weightVSAvoidexercise versatility

Core Design Contradiction:

Weight of moving objectVSAdaptability or versatility

Solution Approach 1:

The patent applies dimensionality change by adding spatial configuration as a new dimension of versatility. Instead of relying solely on weight magnitude, the system provides exercise variety through three-dimensional arm positioning, angle adjustment, and weight plate placement variations, enabling diverse exercises with portable weight plate equipment

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

4Adaptability or versatility

If arm assemblies are made adjustable to accommodate different exercises and users, then adaptability is improved, but device complexity increases

Engineering Contradiction:

Improveexercise adaptabilityVSAvoidassembly complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by creating modular arm assemblies that can be independently configured and attached to the weight rack. Each arm assembly is a separate unit with its own adjustment mechanisms, allowing complexity to be distributed across multiple simple modules rather than concentrated in one complex integrated system

Inventive Principle:

Principle #1Segmentation

AI summary

A weight training system for a weight rack includes at least one arm assembly. The at least one arm assembly includes a pivot mount couplable to a rack member of the weight rack, where the pivot mount is height adjustable on the rack member relative to a ground surface; a main arm couplable to the pivot mount, where the main arm is adjustable relative to the pivot mount along a longitudinal axis through a length of the main arm; and a weight attachment couplable to the main arm, where the weight attachment is adjustable relative to the pivot mount along the longitudinal axis through the length of the main arm. A handle attachment and/or a combination weight and handle attachment is couplable to the main arm, each being adjustable relative to the pivot mount along the longitudinal axis through the length of the main arm.
