Solution Overview
Problem
Conventional elliptical exercise machines have fixed exercise trajectories, limiting the user's ability to quickly change walking patterns and spans, failing to satisfy the need for varied exercise experiences.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional elliptical exercise machines use fixed exercise trajectories, then the structure is simple and stable, but the user cannot quickly change walking patterns or adjust exercise types
Solution Approach 1:
The patent applies dynamics by replacing fixed trajectories with dynamically adjustable ones. The swing arms are designed to be movable relative to the supporting frame through lifting mechanisms, allowing the exercise trajectory to change dynamically based on user input. This enables quick adjustment of walking patterns without requiring complete structural redesign, resolving the contradiction between adaptability and complexity.
Solution Approach 2:
The patent segments the exercise machine into independent functional modules: supporting frames, movable swing arms, lifting mechanisms, and linking mechanisms. Each module performs a specific function and can be adjusted independently. The swing arms can be positioned at different heights and angles, allowing users to select various exercise patterns. This modular segmentation enables versatility while keeping each component relatively simple.
2Speed
If actuators are used to adjust exercise trajectory, then some adaptability is achieved, but the operational speed is slow and cannot satisfy quick change needs
Solution Approach 1:
The patent implements self-service by allowing users to directly adjust the swing arm positions through manual lifting mechanisms rather than relying on slow automated actuators. The users can independently control the height and angle of each swing arm according to their exercise needs, achieving immediate trajectory adjustment. This direct user control eliminates the speed limitation of automated systems while maintaining full adaptability.
3Adaptability or versatility
If multiple linking mechanisms are added to enable coordinated movement and pivoting, then the degree of freedom of trajectory is improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple functions into integrated linking mechanisms that simultaneously achieve coordinated movement and pivoting of swing arms. The first linking mechanism connects the movable swing arms to enable coordinated vertical movement, while the second linking mechanism enables coordinated pivoting. By combining these functions into streamlined mechanisms rather than separate complex systems, the patent achieves high trajectory freedom while controlling overall complexity.

AI summary
A free walking training machine includes a chassis having a left supporting frame and a right supporting frame, a left swing arm having a left axial portion extending laterally, a right swing arm having a right axial portion extending laterally, a left lifting mechanism, a right lifting mechanism, a first linking unit, and a second linking unit. The left lifting mechanism makes the left swing arm move upward and downward relative to the left supporting frame. The right lifting mechanism makes the right swing arm move upward and downward relative to the right supporting frame. The first and second linking mechanisms are connected with the left and right swing arms for enabling the left and right axial portions and the left and right swing arms to make coordinated movement and move in opposite directions, respectively. The first and second linking mechanisms are operable independently.
