Gymnastic Machine Resisting Device Abdomen Constraint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding belt gymnastic machines face issues with bulkiness and safety due to external resisting devices, which obstruct movement and pose risks during exercises, and coupling resisting devices to the user's legs complicates the performance of gymnastic exercises.
Innovation Solution
A closed circuit sliding belt machine with a wearable resisting device that constrains the abdomen, allowing free movement of the upper and lower limbs, coupled with handles and a deformable resisting mechanism that exerts force opposite to the user's running direction, reducing encumbrance and enhancing safety by integrating the resisting device within the machine's structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the resisting device is installed on an external structure behind the user, then the user can perform gymnastic exercises with resistance, but the overall bulk within the space increases and the user may hit against the external structure during accidental falls
Solution Approach 1:
The resisting device is nested within the frame structure of the exercise machine. Specifically, the resisting device is coupled to the frame between the sliding belt and the user, integrating it into the existing structure rather than placing it externally. This nesting approach reduces the overall bulk while maintaining safety functions.
Solution Approach 2:
The resisting device is extracted from the external structure and repositioned to be coupled directly to the frame of the exercise machine. This extraction eliminates the need for separate external support structures, reducing the overall bulk while maintaining the resistance function.
2Volume of stationary object
If the resisting device is coupled with the supporting structure or frame of the exercise machine, then the encumbrance is reduced, but the user has legs placed under the resisting device which makes gymnastic exercise difficult
Solution Approach 1:
The resisting device is positioned to constrain only the abdomen region of the user, while leaving the lower and upper limbs free to move. This localized constraint approach allows the user to perform coordinated limb movements necessary for gymnastic exercises while still providing the resistance function.
Solution Approach 2:
The resisting device is designed to constrain specific body parts (abdomen) while leaving other parts (limbs) free. This segmentation of constraint allows for both compact integration and ease of exercise performance by differentiating between constrained and free movement zones.
3Ease of operation
If the resisting device constrains the user's abdomen and leaves limbs free to move, then coordinated limb movement is enabled, but the device complexity increases
Solution Approach 1:
The resisting device serves multiple functions: it provides resistance, constrains the abdomen, and allows free limb movement. By integrating these functions into a single device coupled to the frame, the complexity is managed while achieving the desired ease of operation.
4Area of stationary object
If the resisting device is integrated within the machine structure with handles coupled to the frame, then space for easy access is improved, but the coupling mechanism complexity increases
Solution Approach 1:
The coupling mechanism is segmented into separate components: handles coupled to the frame at specific positions, and the resisting device coupled to the handles. This segmentation allows for simplified individual components while maintaining the overall integration benefits.
