Back Exercise Equipment with Linked Handle and Disk for Compact One-Arm Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing back exercise equipment lacks the ability to perform deep lower back stimulation with one-arm operations and often requires large spaces, making it inconvenient for users.
Innovation Solution
The back exercise equipment features a support frame, body frame, rotating part, grip part, lifting part, and seating part, allowing for independent arm movement, customizable motions with various handles, and a compact design by linking the handle and disk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional back exercise equipment is used, then exercise functionality is provided, but it occupies large space and cannot perform deep lower back stimulation with one-arm operation
Solution Approach 1:
The exercise equipment is divided into independent left and right rotating parts, each capable of independent rotation and exercise execution. This segmentation enables one-arm operation while maintaining compact size, as only one side needs to be active at a time rather than requiring a full two-sided apparatus.
Solution Approach 2:
The handle and disk are fastened in a linked nested structure where the handle is connected to the disk assembly. This nesting reduces the overall footprint and allows the components to occupy minimal space when not in use, while still providing full exercise functionality when activated.
2Reliability
If traditional back exercise equipment is used, then exercise functionality is provided, but it cannot provide deep stimulation to the lower back
Solution Approach 1:
The equipment features dynamic rotating parts that can rotate in multiple directions and at different angles, allowing the user to adjust the motion trajectory and intensity. This dynamic capability enables deep lower back stimulation through controlled rotational movements while maintaining versatility for different exercise variations.
Solution Approach 2:
The handle is designed with specific curvature and positioning that concentrates the exercise force on the lower back region. The local geometry of the handle and disk assembly creates focused stimulation on target muscle groups rather than distributing force uniformly, thereby enhancing lower back stimulation effectiveness.
3Adaptability or versatility
If multiple exercise types are provided, then adaptability is improved, but device complexity increases
Solution Approach 1:
The rotating part serves multiple functions: it acts as both the rotating mechanism and the exercise lever, the handle serves as both grip and resistance applicator, and the disk serves as both weight counterweight and exercise component. This multi-functionality achieves exercise variety without proportionally increasing structural complexity.
Solution Approach 2:
The handle and disk are merged into a single linked assembly rather than separate components. This merging reduces the number of independent parts and simplifies the overall structure while still enabling multiple exercise variations through the coordinated movement of the integrated assembly.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables effective single-arm back exercises that deeply stimulate the lower back, allows for customized motion options, and occupies minimal space due to its linked handle and disk structure.
Implementation Method 1
when the external force is released by the user, it can return along the descending path due to the weight of the weight plate mounted on the lifting part

AI summary
A back exercise equipment includes a support frame seated on the bottom surface, a body frame connected to the support frame to form a support structure, a rotating part rotatably mounted to the body frame, a grip part connected to one end of the rotating part and providing a space for the user to grip, a lifting part that is connected to the other end of the rotating part, moves up and down being interlocked with the rotation of the rotating unit and provides a space in which a plate is mounted, and a seating part connected to the support frame and disposed in front of the body frame to provide a space in which the user can sit.
