Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mat-type exercise devices face challenges in ensuring horizontal movement while maintaining user stability during exercises, particularly when components like motors are included, and require easy manipulation for moving and seating on a floor.
Innovation Solution
The device incorporates wheel modules that can move between protrusion and introduction positions, switched by a manipulation mechanism, allowing for horizontal movement and stable exercise, with elastic forces aiding in wheel positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the mat-type exercise device includes components such as a motor to provide exercise load, then the exercise functionality is improved, but the device becomes difficult for a user to directly carry and move
Solution Approach 1:
The device body is divided into an upper body and a lower body that can be relatively moved with respect to each other. The lower body includes a seat and wheels, while the upper body includes exercise equipment. This segmentation allows the device to be moved by shifting the upper body relative to the lower body, making it easier to relocate despite having motor components.
Solution Approach 2:
The device employs dynamic positioning through wheels that can be switched between protruding and retracted positions. The lower body can be freely moved horizontally on the floor using the wheels, and the upper body can be relatively moved with respect to the lower body during exercise. This dynamic structure enables both mobility and stability during use.
2Ease of operation
If the device ensures free horizontal movement on the floor, then the mobility is improved, but the user's stability during exercise may be compromised
Solution Approach 1:
The device uses a dynamic wheel system that can switch between protruding and retracted positions. During movement, the wheels protrude to enable free horizontal movement. During exercise, the wheels are retracted to provide stability. This dynamic adjustment resolves the contradiction between mobility and stability.
Solution Approach 2:
The device separates the movement function (lower body with wheels) from the exercise function (upper body with equipment). The lower body provides mobility through wheels, while the upper body provides stability during exercise. This functional segmentation allows both mobility and stability to coexist.
3Ease of operation
If multiple wheel modules are used to ensure mobility, then the horizontal movement capability is improved, but the complexity of manipulating multiple wheels increases
Solution Approach 1:
Multiple wheel modules are integrated into a unified lower body structure. All wheel modules are switched between protruding and retracted positions through a single switching module, combining multiple functions into one control mechanism. This reduces operational complexity while maintaining mobility benefits.
Solution Approach 2:
The switching module serves multiple functions: it controls all wheel modules simultaneously, provides elastic force for wheel positioning, and maintains the device in stable positions. This multi-functionality reduces the need for separate mechanisms for each wheel, simplifying the overall system.

AI summary
Proposed is a mat-type exercise device. The mat-type exercise device may include a plurality of wheel modules. Each of the plurality of wheel modules is installed in the device body such that the wheel module can move between a protrusion position at which the wheel module protrudes from the lower surface of the device body and an introduction position at which the wheel module is introduced to the inside of the lower surface of the device body. Additionally, a plurality of switching modules switches the position of at least one of the plurality of wheel modules between the protrusion position and the introduction position. Accordingly, the mat-type exercise device is secured to move horizontally when the wheel module is located at the protrusion position, and stable exercise is secured when the wheel module is located at the introduction position.
