Weight-Adjustable Exercise Device With Segmented Plates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gym and fitness equipment, such as dumbbells and barbells, occupy excessive space due to their fixed or adjustable weight configurations, and lack a compact, weight-adjustable solution that targets specific muscles while ensuring proper weight distribution.
Innovation Solution
A compact, weight-adjustable free-weight exercise device featuring a tubular housing with adjustable weighted plates and locking pins, allowing for customizable weight settings and ergonomic handling for various exercises, accommodating underhand and overhand grips, and facilitating easy storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple dumbbells with fixed weights are used to accommodate different strength levels, then weight adaptability is improved, but space occupation increases
Solution Approach 1:
The device divides the weight system into separate, removable weight plates that can be independently selected and combined. Each weight plate is a discrete unit that can be attached or detached from the handle, allowing users to create different weight configurations without needing multiple complete dumbbell sets.
Solution Approach 2:
The device creates a universal weight system where a single handle can work with multiple weight plates of different masses. This multi-functional design allows one base unit to serve multiple weight training purposes, replacing the need for multiple specialized dumbbells.
2Adaptability or versatility
If a barbell with adjustable weights is used, then weight adaptability is improved, but space occupation and device complexity increase
Solution Approach 1:
The weight adjustment mechanism is segmented into simple, independent components: weight plates with engagement features and corresponding receptacles on the handle. This segmentation avoids the complex mechanical systems found in traditional adjustable barbells while achieving the same weight variability.
Solution Approach 2:
The invention extracts the weight selection function from a complex mechanical adjustment system and implements it through simple, removable weight plates. This removes unnecessary complexity while preserving the essential weight adaptability function.
3Stability of the object's composition
If kettlebells with fixed weights are used, then proper weight distribution is improved, but space occupation increases
Solution Approach 1:
The device segments the weight into removable plates that can be precisely configured, allowing for optimized weight distribution similar to kettlebells but with the flexibility to adjust the total weight. The modular design maintains compact form while enabling weight customization.
Solution Approach 2:
The weight plates are nested within or attached to the handle structure, creating a compact configuration when not in use. This nesting approach allows multiple weight components to occupy minimal space while maintaining proper weight distribution during exercise.

AI summary
A weight-adjustable free-weight exercise device is a portable and ergonomic exercise apparatus. The apparatus allows the weight to be varied according to the strength of the user and the type of exercise being performed by the user. The apparatus includes a tubular housing, a left handle, a right handle, at least one weighted plate, a first locking pin, and a second locking pin. The tubular housing contains the at least one weighted plate. The left handle and the right handle allow a user to grip the apparatus. The at least one weighted plate defines the overall weight of the apparatus. The first locking pin and the second locking pin secures the position of the at least one weighted plate within the tubular housing. The apparatus may further include a first cap and a second cap that fully enclose the at least one weighted plate within the tubular housing.
