Multi-Grip Weight Bar With Pad Spacers for Range-of-Motion Control

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing weight bars and spacers used in exercises are inconvenient, unsafe, and limit the range of motion and gripping options, requiring additional users to hold spacers or allowing them to rotate out of position during exercises.

Innovation Solution

An exercise apparatus with a grip section, sleeves, and a support platform that securely mounts pad spacers to limit exercise movements, providing versatile gripping options and adjustable ranges of motion, and a pad assembly that attaches to weight bars to restrict movement during pressing exercises.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional spacers are used to limit range of motion during exercises, then exercise safety is improved, but additional users are required to hold the spacers in place

Engineering Contradiction:

Improveexercise safetyVSAvoidconvenience of use

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The pad spacer assembly is designed to be self-holding through friction engagement between the pad spacer and the bar shaft, eliminating the need for additional users to hold the spacers in place during exercises

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The pad assembly acts as an intermediary between the user and the bar, providing a secure interface that limits range of motion without requiring human assistance to maintain position

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If traditional spacers are used to limit range of motion, then exercise safety is improved, but the spacers can rotate out of position during exercises

Engineering Contradiction:

Improveexercise safetyVSAvoidposition stability

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Instead of trying to prevent rotation through active control, the design allows the pad spacer to engage the bar shaft in a way that naturally resists rotation through friction and geometric constraints

Inventive Principle:

Principle #13The other way round (Inversion)

3Adaptability or versatility

If a standard Olympic bar with round shaft is used, then gripping options are limited, but the bar structure is simple

Engineering Contradiction:

Improvegripping optionsVSAvoidbar structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The bar features localized grip supports with different geometries (flat, contoured, angled) at specific positions along the shaft, providing varied gripping options only where needed while maintaining a simple overall structure

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The bar is segmented into distinct functional zones: grip supports for hand placement, knurled sections for enhanced grip, and smooth sections for bar movement, allowing each segment to serve its specific purpose

Inventive Principle:

Principle #1Segmentation

AI summary

An exercise apparatus includes a grip section including at least one pair of handles; a first sleeve coupled to a first end of the grip section; and a second sleeve coupled to a second end of the grip section, which is opposite the first end. Each of the first and second sleeves is structured to receive one or more weight plates. The grip section includes a first grip segment, a second grip segment, and a platform positioned between the first grip segment and the second grip segment.
