Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional exercise device supporting structures fail to allow easy and quick conversion of dumbbell devices to barbell devices, limiting their versatility and functionality.
Innovation Solution
A dumbbell and barbell supporting system with an adjustable configuration, featuring rotatable tables, carriers, and brackets that enable weight plates to be attached to a bar, allowing for seamless conversion between dumbbell and barbell modes by pivoting and sliding mechanisms, with spring biased catches and locks for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional exercise device supporting structure is used, then the structure is simple and stable, but it cannot support both dumbbell and barbell configurations and requires separate devices for different exercise modes
Solution Approach 1:
The supporting structure is designed to serve multiple functions: it can support dumbbells on inclined tables for traditional exercises, and simultaneously support barbells on a horizontal table for different exercises. The base unit with multiple rotatable tables and adjustable carriers enables one structure to replace multiple dedicated structures, achieving universality across different exercise device configurations.
Solution Approach 2:
The supporting system is divided into independent functional modules: a base structure, multiple rotatable tables (first and second tables for dumbbells, third table for barbell), carriers for weight members, and a horizontal table for the bar. This segmentation allows each module to be independently adjusted and positioned to accommodate different exercise configurations without requiring complete structural redesign.
2Ease of operation
If weight members are fixed to handlebars for dumbbell configuration, then the dumbbell structure is stable, but conversion to barbell configuration requires time-consuming disassembly and reassembly
Solution Approach 1:
The system employs dynamic, adjustable connections rather than fixed attachments. The carriers are rotatably mounted on table pivots and can be easily repositioned between inclined and horizontal positions. The spring-loaded catches provide quick-release functionality, allowing weight members to be rapidly transferred from dumbbell handlebars to the barbell configuration without time-consuming fastening or unfastening operations.
Solution Approach 2:
The carriers serve as intermediary components between the weight members and the supporting tables. These carriers with spring-loaded catches provide a mechanical mediation system that facilitates quick transfer of weight members between different configurations. The intermediary carriers absorb the complexity of the conversion process, allowing users to simply reposition the carriers rather than directly manipulating the weight members and handlebars.
3Adaptability or versatility
If the supporting structure is designed for stable weight support, then the structure is rigid and secure, but adjustment and reconfiguration between exercise modes becomes difficult
Solution Approach 1:
The structure employs dynamic elements (rotatable tables, movable carriers) combined with stable support mechanisms (spring-loaded catches, locked positions). The tables can rotate to different angles while the carriers provide stable, secure holding positions during exercise. This dynamic design allows the structure to be rigid when needed for stability and flexible when adjustment is required.
Solution Approach 2:
The invention merges the stability function and adjustability function into a single integrated system. The spring-loaded catches simultaneously provide secure weight support and easy release for reconfiguration. The rotatable tables provide both stable inclined positions for dumbbell exercises and stable horizontal position for barbell exercises, combining multiple functions in unified structural elements rather than separate systems.

AI summary
A dumbbell and barbell supporting system includes two tables rotatably attached to a base and rotatable relative to the base to two working positions where the tables are inclined relative to each other or are in line with each other, and two dumbbells disposed on the tables, the dumbbells each include two or more weight members or two weight elements, and a handlebar engageable with the weight members and the weight elements for detachably coupling the weight members and the weight elements to the handlebar, the tables are rotatable to be in lined with each other, and a longitudinal bar engageable with the weight members and the weight elements for forming a barbell exerciser device.
