Gymnastic Machine with Inclined Support and Lockable Pulley
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gymnastic machines fail to ensure correct posture and safety during exercises, leading to potential injury and inadequate muscle workout, as they do not prevent users from arching their back and require assistance during high-intensity workouts.
Innovation Solution
A gymnastic machine with an inclined back support and foot platform, allowing users to stand upright and adjust the angle for optimal posture, combined with safety mechanisms that allow users to lock the movement of the loading unit without external help, ensuring symmetrical muscle engagement and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional flat or slant benches are used, then the machine structure is simple, but the user cannot maintain correct posture during exercise
Solution Approach 1:
The back support is made adjustable with multiple inclination positions, allowing the user to dynamically adapt the support angle to maintain correct posture throughout the exercise range of motion, preventing back arching while keeping the overall structure relatively simple
2Device complexity
If conventional benches without safety means are used, then the device complexity is low, but user safety is compromised during high-intensity exercises
Solution Approach 1:
The safety mechanism is designed as a self-operating system with a release button that allows the user to independently engage and disengage the locking mechanism on the loading unit, eliminating the need for external assistance while maintaining safety during high-intensity exercises
3Ease of manufacture
If conventional benches are used, then the machine is easy to manufacture, but symmetrical muscle engagement cannot be ensured
Solution Approach 1:
The back support is designed with a specific curved contour that asymmetrically conforms to the natural curvature of the human spine, providing targeted support at key anatomical points to enforce proper alignment and promote symmetrical muscle engagement during the exercise
4Device complexity
If conventional benches are used, then the structure is simple, but the user may arch the back causing injury
Solution Approach 1:
The back support is pre-configured with an inclined geometry that counteracts the natural tendency to arch the back during exercise, providing proactive postural correction before harmful movements can occur, thereby preventing injury while maintaining structural simplicity
