Twisting Stepper Apparatus With Dual Lever Foot Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stepper machines do not effectively engage the lower body muscle groups with a twisting motion, limiting the variety and effectiveness of exercise routines.
Innovation Solution
A Twisting Stepper Apparatus comprising a Frame Structure Member, a Foot Engagement Member with a Dual Lever Assembly, and an optional Resistance Member, which allows for a unique twisting motion by pivoting foot pedals that move in reciprocating upward and downward motions, engaging a slanted Guide Platform Member to create a side-to-side twisting motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional stepper machines are used, then the exercise routine is simple and easy to operate, but the lower body muscle groups are not effectively engaged with a twisting motion
Solution Approach 1:
The patent applies the dynamics principle by implementing a pivoting mechanism that allows the foot pedals to rotate and twist during the stepping motion. The foot engagement member is pivotally mounted to the base frame member, enabling it to dynamically change orientation from a fixed conventional position. This pivoting action creates a twisting motion that engages lower body muscle groups more effectively while maintaining ease of operation through natural stepping movements.
2Adaptability or versatility
If a pivoting mechanism is added to create twisting motion, then the exercise effectiveness is improved, but the device complexity increases
Solution Approach 1:
The patent applies the merging principle by integrating the pivoting mechanism directly into the existing foot engagement member structure. The foot engagement member combines the pedal support function with the pivoting capability in a single integrated component assembly. This merging approach creates the twisting motion effect without adding separate complex mechanisms, thereby improving exercise effectiveness while minimizing the increase in device complexity.
3Adaptability or versatility
If the foot support members move in reciprocating upward and downward motions, then the twisting motion is created, but the structural stability may be compromised
Solution Approach 1:
The patent applies the segmentation principle by dividing the foot engagement system into multiple independent pivotally mounted components. The foot engagement member is segmented into separate foot support members that can pivot independently relative to the base frame member. This segmentation allows each component to move freely to create the twisting motion while maintaining overall structural stability through the distributed pivot connections that allow controlled movement without compromising the frame's integrity.

AI summary
A Twisting Stepper Apparatus comprising a Frame Structure Member, a Foot Engagement Member, and an optional Resistance Member. The Frame Structure Member is comprised basically of a Base Frame Member and a Guide Platform Member. The Foot Engagement Member is pivotally mounted to the Base Frame Member and mainly comprises two Foot Support Members pivotally coupled together by a lever assembly such that they move in reciprocating upward and downward motions. The lever assembly is a dual lever assembly which keeps the Foot Support Member in a relatively horizontal positon while moving upward and downward. The Foot Support Members operatively engage the Guide Platform Member, with the upward and downward movements of the Foot Support Members create the twisting movement of the Foot Engagement Member, and vice versa. The optional Resistance Member provides resistance in the twisting motion of the Foot Engagement Member, and thus also in the upward and downward movements of the Foot Support Members.
