Exercise Machine Gear Shifting for Multi-Muscle Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise machines are limited to training specific muscle groups, requiring multiple machines for comprehensive workouts.
Innovation Solution
A multifunctional exercise machine with a supporting frame, load group, and gear shifting mechanism that allows selective coupling to different operating groups, controlled by a logic unit for various exercises, including biceps, triceps, abdominals, pectorals, shoulders, and quadriceps, with adjustable resistance and exercise starting positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single exercise machine is designed to train only one specific muscle group, then the machine can be simple and easy to operate, but multiple machines are required to train different muscle groups
Solution Approach 1:
The exercise machine is designed with multiple operating groups (first, second, third operating groups) that can be selectively engaged through a gear shifting mechanism, allowing a single machine to perform exercises for different muscle groups including biceps, triceps, abdominals, pectorals, shoulders, and back, thereby eliminating the need for multiple separate machines
Solution Approach 2:
The machine divides its functionality into distinct operating groups, each dedicated to specific muscle groups, with a gear shifting mechanism that selectively couples the load group to different operating groups, enabling independent control and selection of exercise modes without increasing overall machine complexity
2Adaptability or versatility
If multiple exercise machines are used to train different muscle groups, then each machine can be simple and dedicated, but the space requirement and equipment cost increase
Solution Approach 1:
The machine consolidates multiple workout functions into a single unit, providing comprehensive muscle group training capability within one machine footprint, thereby reducing the space required compared to having separate machines for each muscle group
3Adaptability or versatility
If a gear shifting mechanism is added to enable multiple operating groups, then the machine becomes multifunctional, but the device complexity increases
Solution Approach 1:
The transmission system is segmented into distinct gear shifting mechanisms that selectively couple the load group to specific operating groups, allowing independent control of each exercise mode without requiring a completely complex transmission system, thereby managing overall device complexity
4Extent of automation
If automatic gear shifting controlled by a logic unit is implemented, then workout sequences can be automated, but the device complexity and cost increase
Solution Approach 1:
The logic control unit automatically manages gear shifting and load group selection based on pre-programmed workout sequences, enabling the machine to self-regulate exercise transitions without requiring manual intervention, thereby providing automated workout programs while keeping control system complexity manageable
