Solution Overview

Problem

Conventional bodybuilding equipment requires weight towers for load adjustment, occupying significant space and incurring high costs due to complex construction and maintenance, and existing solutions fail to eliminate the need for weight towers while ensuring ergonomic and compact design.

Innovation Solution

A bodybuilding equipment with a profile that allows direct pivoting and weight adjustment through a slidable weight element, eliminating the need for weight towers by using a weight adjustment device that is pivotable and selectively attachable/detachable via a fastening element, allowing compact and ergonomic use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If weight towers are used for load adjustment, then weight adjustment capability is provided, but space occupation increases and construction complexity increases

Engineering Contradiction:

Improveweight adjustment capabilityVSAvoidspace occupation

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent extracts and eliminates the weight tower component from the bodybuilding equipment, replacing it with a compact weight adjustment mechanism that integrates directly into the equipment structure. This removes the need for separate weight towers while maintaining weight adjustment functionality, thereby reducing space occupation.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The weight adjustment mechanism is merged with the main equipment structure rather than being a separate tower component. The weight stack and adjustment mechanisms are integrated into the equipment frame, combining multiple functions into a unified structure that reduces overall space requirements.

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If weight towers are used for load adjustment, then weight adjustment capability is provided, but manufacturing and maintenance costs increase

Engineering Contradiction:

Improveweight adjustment capabilityVSAvoidmanufacturing and maintenance costs

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By removing the weight tower component, the patent eliminates the manufacturing and maintenance costs associated with producing and servicing separate tower structures, while preserving the essential weight adjustment function through an integrated mechanism.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The integrated weight adjustment mechanism serves multiple functions within a single structure, combining weight support, adjustment, and stabilization functions that were previously distributed across separate components including the weight tower, thereby reducing manufacturing complexity and maintenance requirements.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If pins and weight towers are used for weight adjustment, then weight selection is enabled, but operational convenience deteriorates due to manual pin manipulation

Engineering Contradiction:

Improveweight selection capabilityVSAvoidoperational convenience

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The weight adjustment mechanism is designed to be self-servicing, allowing users to easily select and adjust weights without requiring separate pin manipulation. The integrated design enables direct weight selection through the equipment's own structure, eliminating the need for additional manual operations with pins.

Inventive Principle:

Principle #25Self-service

4Adaptability or versatility

If weight towers with multiple components are used, then weight adjustment is enabled, but device complexity increases

Engineering Contradiction:

Improveweight adjustment capabilityVSAvoidconstruction complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent removes the weight tower and its associated complex components (cables, pulleys, multiple rods, and pins) from the system, replacing them with a simplified integrated weight adjustment mechanism that achieves the same functional outcome with fewer parts and lower structural complexity.

Inventive Principle:

Principle #2Taking out (Extraction)
