Solution Overview

Problem

Existing exercise systems, particularly those using dumbbells, face challenges in maintaining user engagement due to delayed gratification from slow external body changes, leading to inconsistent workout regimes.

Innovation Solution

An adjustable weight exercise system is introduced, featuring a permanent weight assembly and interlocking weights that can be locked or unlocked based on user settings, combined with haptic feedback and gamification elements to enhance engagement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional dumbbells are used for exercise, then the exercise system is simple and straightforward, but user engagement is low due to delayed gratification from slow external body changes

Engineering Contradiction:
Improvesimplicity of exercise systemVSAvoiduser engagement
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent implements feedback mechanisms through haptic devices that provide tactile responses during exercise, and through digital interfaces that display real-time performance data and progress tracking. This immediate feedback loop enhances user engagement by making workout progress visible and tangible, directly addressing the delayed gratification problem while maintaining operational simplicity.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces traditional purely mechanical dumbbells with an enhanced system incorporating electronic components including sensors, haptic feedback devices, and digital display interfaces. This substitution transforms the exercise experience from passive mechanical resistance to an interactive system that provides real-time feedback and engagement without complicating the basic exercise mechanism.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If interlocking weights are added to the exercise system, then weight adjustability is improved, but device complexity increases

Engineering Contradiction:
Improveweight adjustabilityVSAvoidsystem structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the weight system into modular interlocking components where weights can be independently selected and attached. Each weight unit is a separate module that can be combined with the handle through simple interlocking mechanisms, allowing users to customize weight configurations without requiring a completely different device for each weight level.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic weight adjustment capabilities where the system can change weight configurations during exercise sessions. The interlocking mechanism allows for quick weight changes without requiring complex tools or procedures, enabling users to adapt weight levels dynamically based on workout progress and requirements.

Inventive Principle:
Principle #15Dynamics

AI summary

An adjustable weight exercise system is provided. A permanent weight assembly and a plurality of interlocking weights are provided. A base comprises an interlocking weight carrier, wherein the interlocking weights are supported on the interlocking weight carrier and an interlocking weight selector, wherein the interlocking weight selector is adapted to cause interlocking weights to be set to be locked to the permanent weight assembly while the permanent weight assembly is not on the base, wherein placement of the permanent weight assembly on the base causes interlocking weights that are set to be locked to the permanent weight assembly to be locked to the permanent weight assembly, and wherein placement of the permanent weight assembly on the base does not cause interlocking weights that are not set to be locked to the permanent weight assembly to be locked to the permanent weight assembly.
