Stationary Exercise Apparatus with Adjustable Incline and Stride Length
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stationary exercise apparatuses lack variety in exercise experience and intensity, primarily relying on speed adjustments and limited incline or stride length modifications to enhance workout intensity.
Innovation Solution
A stationary exercise apparatus with a frame, supporting members, and pedals that move along a closed path with adjustable incline and stride length, allowing for varied exercise intensity and better gluteus engagement through a combination of arcuate reciprocating and closed paths, controlled via a console or manual adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If exercise intensity is increased by adjusting incline or stride length, then exercise effectiveness is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic adjustability of the footpath by allowing the linear track to be repositioned along the frame structure. This enables the incline angle and stride length to be varied during exercise, providing multiple exercise intensities and types without requiring multiple fixed mechanisms. The dynamic adjustment capability allows users to switch between different exercise modes (e.g., walking, running, uphill walking) by simply repositioning the track.
Solution Approach 2:
The exercise apparatus is designed to perform multiple exercise functions through a single integrated structure. By combining the adjustable linear track with the pedal mechanism, the device can provide various exercise intensities and types (walking, running, uphill walking) without requiring separate dedicated mechanisms for each function. This multi-functionality is achieved through the versatile footpath adjustment capability that accommodates different exercise patterns.
2Adaptability or versatility
If the footpath is made adjustable to vary exercise experience, then exercise variety is improved, but ease of operation deteriorates
Solution Approach 1:
The linear track is designed to be dynamically repositionable along the frame structure through simple adjustment mechanisms. Users can easily change the track position to vary the incline angle and stride length, providing different exercise experiences. The dynamic adjustment is implemented in a way that maintains operational simplicity, allowing users to switch between exercise modes without complex procedures.
3Adaptability or versatility
If the apparatus provides multiple exercise modes through path adjustment, then adaptability is improved, but device complexity increases
Solution Approach 1:
The apparatus achieves multiple exercise modes through a single universal footpath adjustment mechanism rather than separate dedicated mechanisms for each exercise type. The linear track can be repositioned to provide various incline angles and stride lengths, enabling walking, running, uphill walking, and other exercise patterns within one integrated system. This universal approach provides adaptability without proportionally increasing device complexity.
