Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current exercise machines fail to effectively exercise both flexor and extensor muscles simultaneously, often requiring separate machines and are typically expensive.
Innovation Solution
A cost-effective exercise device featuring a base with interlocking teeth sidewalls, an elongated rod with gears, and a board that applies pressure to move the rod along the sidewalls, engaging both flexor and extensor muscles through a mechanism of interlocking gears and a fulcrum system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single exercise device is designed to exercise both flexor and extensor muscles, then the need for multiple machines is eliminated and cost is reduced, but the device complexity increases significantly
Solution Approach 1:
The patent combines flexor and extensor exercise functions into a single device by integrating two exercise mechanisms that share common structural elements. The first and second exercise mechanisms are merged through shared components including the base, sidewalls with teeth, elongated rod, and board, allowing users to exercise both muscle groups with one device rather than requiring separate machines
Solution Approach 2:
The exercise device is designed with universal components that serve multiple functions. The elongated rod acts as both a support structure and a moving component for both exercise mechanisms. The board serves as the interface for user input in both flexor and extensor exercises. The gear system on the rod provides resistance for both types of muscle groups, making the device multi-functional
2Adaptability or versatility
If expensive exercise machines are used to exercise both flexor and extensor muscles, then the functionality is achieved, but the cost increases significantly
Solution Approach 1:
The device is segmented into modular components that can be manufactured separately and assembled. The base, sidewalls, elongated rod, gears, and board are distinct segments that can be produced using standard manufacturing processes. This segmentation allows for cost-effective production compared to expensive integrated exercise machines, while still achieving the dual muscle group exercise functionality
Solution Approach 2:
The patent employs simple, inexpensive components such as toothed sidewalls, basic gear mechanisms, and a straightforward rod-and-board assembly. These components use conventional materials and manufacturing methods rather than expensive specialized parts, making the device affordable while maintaining the capability to exercise both flexor and extensor muscles
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables simultaneous exercise of both flexor and extensor muscles in a single, affordable device, providing resistance and deceleration to effectively target muscle groups without the need for multiple machines.
Implementation Method 1
at least a first gear secured to the first end of the elongated rod comprising a plurality of teeth interlocked with the plurality of teeth of the first sidewall; at least a second gear secured to the second end of the elongated rod and comprising a plurality of teeth interlocked with the plurality of teeth of the second sidewall
Implementation Method 2
a board resting on the elongated rod in between the first end and the second end

AI summary
An exercise device that exercises both flexor and extensor muscles. The exercise device includes a base. First and second sidewalls upwardly extend from opposing sides of the base. Each of the first and second sidewall has a plurality of teeth formed on an upper rim extending from the front end to the rear end of the base. At least a first gear is secured to a first end of an elongated rod and at least a second gear is secured to a second end of the elongated rod. A plurality of teeth of the first gear interlock with the plurality of teeth of the first sidewall and a plurality of teeth of the second gear interlock with the plurality of teeth of the second sidewall. A board rests on the elongated rod in between the first end and the second end.
