Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional exercise training equipment can only provide either linked or independent training modes, limiting the diversity of physical training and reducing the effectiveness of exercise or rehabilitation.
Innovation Solution
An exercise device with controllable training modes, featuring a base, first and second exercise mechanisms, and an operating mechanism with a third gear member that can switch between linked and free states, allowing users to freely choose between linked and independent training modes by adjusting the gear engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional exercise training equipment is designed to provide only linked or independent training mode, then the device structure is simple, but the training diversity and effectiveness are limited
Solution Approach 1:
The exercise device employs a dynamic configuration system where the connection between left and right exercise mechanisms can be switched between connected and disconnected states through a connection mechanism. This allows the device to adapt its structure in real-time, transforming from a static single-mode device to a dynamic multi-mode device, thereby resolving the contradiction between training diversity and structural simplicity
Solution Approach 2:
The exercise device integrates multiple training functions into a single device by incorporating both linked training capability (through gear connection) and independent training capability (through gear disconnection). The universal design allows one device to serve multiple purposes - either simultaneously training both sides or independently training either side, thus improving adaptability without requiring separate dedicated equipment for each training mode
2Adaptability or versatility
If the exercise device allows switching between linked and independent training modes, then training effectiveness is enhanced, but the device complexity increases
Solution Approach 1:
The connection mechanism acts as an intermediary element between the left and right exercise mechanisms. This intermediary component (comprising connection gears and connecting rods) enables the switching function between connected and disconnected states, providing a simple and elegant solution that avoids complex control systems while achieving mode transformation
Solution Approach 2:
The exercise device employs a self-service switching mechanism where the connection and disconnection of training modes is achieved through the natural interaction of gear components. When the user operates the exercise equipment, the gear mechanisms automatically engage or disengage based on the training requirements, reducing the need for external control systems and simplifying the overall device structure

Function Achieved in This Case
Enables users to switch between linked and independent training modes, providing a variety of physical training options that enhance the effectiveness of exercise or rehabilitation by allowing individual adjustment of swing angles and modes based on training needs.
Implementation Method 1
the third gear member meshes with the first gear member and the second gear member to form a linked state, so that the first exercise mechanism and the second exercise mechanism are operatively linked and coupled and swing in opposite directions via the third gear member

AI summary
An exercise device with controllable training modes includes a base, a first exercise mechanism, a second exercise mechanism, and an operating mechanism. The first exercise mechanism has a first gear member. The second exercise mechanism has a second gear member. The operating mechanism has a third gear member. When the third gear member is at a first position, the third gear member meshes with the first gear member and the second gear member to form a linked state, so that the first exercise mechanism and the second exercise mechanism are operatively linked and coupled and swing in opposite directions. When the third gear member is at a second position, the third gear member is disengaged from either the first gear member or the second gear member or both to form a free state, so that the first exercise mechanism and the second exercise mechanism individually swing.
