Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing lower body exercise devices fail to effectively target the fine musculature of the toes and feet, and they are often bulky and costly.

Innovation Solution

A compact exercise device with a rectangular prism body and threaded rod system for mounting weights on toes, featuring a dowel mechanism to secure the weights, allowing for targeted muscle engagement of the feet and toes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If large gym equipment such as leg press machines, squat racks, and leg curl/extension machines are used, then lower body exercise capability is improved, but device size and cost increase

Engineering Contradiction:

Improvelower body exercise capabilityVSAvoiddevice size

Core Design Contradiction:

StrengthVSVolume of moving object

Solution Approach 1:

The patent extracts the essential function of lower body exercise from bulky gym equipment by creating a minimal device that attaches directly to the foot. The shoe clip-on device with toe straps and weight attachment removes the need for large machines while maintaining exercise capability through direct foot engagement.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The invention replaces expensive, permanent gym equipment with a simple, affordable clip-on device that can be easily attached and removed. The device uses basic components like straps, clips, and weight plates that are inexpensive compared to commercial gym machinery.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

2Strength

If large gym equipment is used, then lower body exercise capability is improved, but space requirement increases

Engineering Contradiction:

Improvelower body exercise capabilityVSAvoidspace requirement

Core Design Contradiction:

StrengthVSArea of stationary object

Solution Approach 1:

The patent extracts the exercise function from space-consuming gym equipment by creating a portable device that attaches to the user's foot. This eliminates the need for large dedicated exercise spaces while maintaining full lower body workout capability.

Inventive Principle:

Principle #2Taking out (Extraction)

3Strength

If existing exercise devices are used, then general lower body exercise is achieved, but fine musculature of toes and feet is not targeted

Engineering Contradiction:

Improvegeneral lower body muscle engagementVSAvoidtargeting fine musculature capability

Core Design Contradiction:

StrengthVSAdaptability or versatility

Solution Approach 1:

The patent applies local quality by designing a device that specifically targets the fine musculature of the toes and feet through direct attachment to the foot. The toe straps and individual toe engagement provide localized stimulation that general leg machines cannot achieve, while still allowing overall lower body exercise.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The device achieves universality by combining general lower body exercise capability with specific foot and toe muscle targeting. The same clip-on device can be used for both overall leg strengthening and fine motor control of foot muscles, eliminating the need for separate specialized equipment.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An exercise device includes a body with through holes for inserting a user's toes, a partially threaded rod, and a dowel; a weight mounted on the rod and dowel; and a threaded nut fastened to the rod. An exercise method includes gripping the device with a user's toes and actuating a joint on the leg with the device installed. The method exercises the user's lower body, including the fine musculature of the feet and toes.
