Exercise Machine Seat Height Adjustment and Rope Equalization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise machines, such as Pilates reformers, lack easy mechanisms for adjusting the seat height and rope length to accommodate different exercises and user needs, particularly for seamless transitions between exercises.
Innovation Solution
The exercise machine incorporates a seat mechanism with a height adjustment system and a pedal mechanism, allowing for selective adjustment and locking of the seat and bracket position, along with a rope equalizing mechanism to ensure even rope lengths, enhancing user comfort and exercise versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the seat height is made fixed, then the structure is simpler, but the adaptability for different exercises and users is reduced
Solution Approach 1:
The patent applies the dynamics principle by implementing a height adjustment system that allows the seat to transition between fixed and movable states. The seat includes adjustment mechanisms (such as pins, slots, or telescopic components) that enable users to selectively change seat height positions, transforming a static structure into a dynamic one that adapts to different exercise requirements and user preferences.
2Ease of operation
If the rope length is made fixed, then the structure is simpler, but the ease of operation for different exercises is reduced
Solution Approach 1:
The patent applies the dynamics principle to the rope system by incorporating adjustment mechanisms that allow rope length to be dynamically changed between exercises. The ropes include features such as movable connectors, adjustable attachments, or equalizing mechanisms that enable users to modify rope lengths seamlessly, transforming a static rope system into an adaptive one that facilitates easy transitions between different exercise configurations.
3Ease of operation
If the seat is positioned far from the pedal mechanism, then user comfort is improved, but the device complexity increases
Solution Approach 1:
The patent applies the dynamics principle by making the relative position between the seat and pedal mechanism adjustable rather than fixed. The seat height adjustment system and pedal mechanism are coordinated through dynamic positioning, allowing the seat to be elevated to a distance that provides user comfort while maintaining functional connectivity. This dynamic arrangement enables the system to optimize both comfort and coordination without requiring a permanently complex structure.

AI summary
In one aspect of the present exercise machine, an assembly is attached to the end of a reformer, where the assembly comprises a seat mechanism and a pedal mechanism. The seat mechanism has a seat, a bracket supporting the seat, and a height adjustment system, where activation of the height adjustment system permits selective adjustment and locking of the height of the seat and the bracket by restricting travel of the seat and bracket to a slanted path that is slanted relative to the vertical. The pedal mechanism has an axle, a first pedal arm with a first pedal, and a second pedal arm with a second pedal. The pedal mechanism is located directly beneath the seat when the seat mechanism is in a lowest position and partially exposed in a higher position.
