Solution Overview
Problem
Conventional fitness devices for core training have limited exercise modes, requiring multiple devices for varied workouts, which increases cost and space requirements, and multifunctional devices are cumbersome and inconvenient.
Innovation Solution
A multifunctional core training device with a first and second frame body, elastic elements, a sliding structure, and a switch that allows the second frame body to pivot relative to the first, enabling multiple exercise modes such as a rowing machine, abdominal muscle trainer, and Roman chair, with a sliding structure that moves reciprocally on the first frame body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional fitness devices are used for core training, then exercise function is provided, but exercise mode variety is limited and multiple devices are needed
Solution Approach 1:
The patent implements a multifunctional core training device that can perform multiple exercise modes including rowing machine exercises, abdominal muscle training, and Roman chair exercises. The device achieves versatility through a second frame body that can pivot between different positions and a sliding structure that moves reciprocally, allowing a single device to replace multiple specialized fitness equipment
Solution Approach 2:
The device employs dynamic components including a second frame body pivotally connected to the first frame body, allowing the second frame to rotate between different angular positions. Additionally, a sliding structure moves reciprocally along the first frame body, enabling the device to dynamically reconfigure its geometry to support different exercise modes without requiring multiple static devices
2Adaptability or versatility
If multiple fitness devices are used for different exercise modes, then exercise variety is achieved, but cost increases
Solution Approach 1:
The patent implements a multifunctional core training device that can perform multiple exercise modes including rowing machine exercises, abdominal muscle training, and Roman chair exercises. The device achieves versatility through a second frame body that can pivot between different positions and a sliding structure that moves reciprocally, allowing a single device to replace multiple specialized fitness equipment
3Adaptability or versatility
If multiple fitness devices are used for different exercise modes, then exercise variety is achieved, but space requirements increase
Solution Approach 1:
The patent implements a multifunctional core training device that can perform multiple exercise modes including rowing machine exercises, abdominal muscle training, and Roman chair exercises. The device achieves versatility through a second frame body that can pivot between different positions and a sliding structure that moves reciprocally, allowing a single device to replace multiple specialized fitness equipment
Solution Approach 2:
The device employs a compact nested structure where the second frame body is integrated within the footprint of the first frame body. When the second frame pivots to different positions, it utilizes the same spatial envelope, effectively nesting multiple exercise configurations within a single device footprint rather than requiring separate space for each exercise mode
4Adaptability or versatility
If multifunctional fitness device is designed, then exercise mode variety is improved, but device weight increases
Solution Approach 1:
The device employs dynamic components including a second frame body pivotally connected to the first frame body, allowing the second frame to rotate between different angular positions. Additionally, a sliding structure moves reciprocally along the first frame body, enabling the device to dynamically reconfigure its geometry to support different exercise modes without requiring multiple static devices

AI summary
A multifunctional core training device includes a first frame body, a second frame body, a holding device, two elastic elements, two forcing elements, a sliding structure, and a switch. The second frame body is pivotally disposed on the first frame body. The holding device is disposed on the first frame body. The two elastic elements are disposed on the first frame body. The two forcing elements are respectively connected to the two elastic elements. The sliding structure is movably disposed on the first frame body. The switch is disposed on the sliding structure and is for positioning a position of the sliding structure relative to the first frame body. When the second frame body pivots relative to the first frame body, the relative position of the first frame body and the second frame body is changed.
