Solution Overview

Problem

Existing strength training equipment lacks versatility and convenience for outdoor use, particularly in rucking and weight training, failing to provide a compact, customizable, and safe solution for various exercises.

Innovation Solution

A multi-purpose functional ruck weight (FRW) designed with a swing handle and grip handle configurations, allowing for multiple exercise modes, including rucking, dumbbell, and two-handed swinging, with customizable features like textured grips and glow-in-the-dark capabilities for visibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional strength training equipment is used, then exercise functionality is provided, but versatility for multiple exercise modes and outdoor use is limited

Engineering Contradiction:
Improveexercise mode versatilityVSAvoidequipment configuration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The weight plate is designed with multiple handles (swing handle with first aperture, grip handle with second and third apertures) that enable the same object to function across multiple exercise modes including rucking, dumbbell exercises, and two-handed swinging, eliminating the need for separate equipment for each exercise type

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The weight plate incorporates distinct functional segments - the swing handle region with first aperture for rucking and swinging modes, and the grip handle region with second and third apertures for dumbbell exercises - allowing each segment to serve its specific purpose while maintaining overall device simplicity

Inventive Principle:
Principle #1Segmentation

2Volume of moving object

If compact design is implemented for outdoor use, then portability is improved, but safety and visibility during exercise are reduced

Engineering Contradiction:
Improveweight compactnessVSAvoidexercise safety
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The weight plate incorporates glow-in-the-dark material or coatings that cause the plate and/or handles to luminesce in low-light conditions, providing visual feedback to users during exercise and preventing accidental drops while maintaining a compact portable design

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The contoured surfaces are strategically positioned at handle regions where hand contact occurs, providing localized ergonomic benefits and grip security without adding overall volume to the weight plate, thus maintaining compactness while enhancing safety

Inventive Principle:
Principle #3Local quality

3Ease of operation

If contoured surfaces are added to handles, then grip security and ergonomics are improved, but manufacturing complexity increases

Engineering Contradiction:
Improvegrip securityVSAvoidmolding complexity
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The contoured surfaces are integrated directly into the handle regions of the weight plate during the molding process, merging the ergonomic features with the structural handles themselves rather than adding separate components, thereby improving grip security without significantly increasing manufacturing complexity

Inventive Principle:
Principle #5Merging (Combining)

AI summary

Apparatus and associated methods relate to a multi-purpose functional ruck weight (FRW). The FRW includes a packing mode, a two-handed swinging mode, and a dumbbell mode. The FRW is a weight reflectively mirrored about a bisecting longitudinal axis. The weight includes a top and a bottom surface. The FRW includes a swing handle defined by a first aperture extending through the top and bottom surfaces. The weight may be carried in a rucksack against the user's body in a packing mode. The first aperture may be configured such that the first and second hand of the user, in a two-handed swinging mode, are spatially distributed and oriented along intersecting axes. The grip handle may be configured, in a dumbbell mode, such that the user's first hand is inserted through the second and third aperture to grip the grip handle at the center of the FRW.
