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 being expensive when they do.
Innovation Solution
An exercise device with a base, a rotating cylinder, slant boards, and a seat support that allows for adjustable fulcrum positioning, enabling both flexor and extensor muscle exercises with a single, cost-effective machine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single exercise machine is designed to exercise both flexor and extensor muscles, then device versatility is improved, but device complexity increases
Solution Approach 1:
The exercise device incorporates a slant board that can be positioned in multiple configurations to exercise both flexor and extensor muscles. The slant board pivots on a rotating cylinder that can be set to different angles, allowing the same basic structure to serve multiple muscle groups without requiring separate machines.
Solution Approach 2:
The fulcrum position is made adjustable along the base, allowing users to change the pivot point location to target different muscle groups. This dynamic reconfigurability enables a single device to adapt to various exercise requirements while maintaining a relatively simple overall structure.
2Device complexity
If separate machines are used for flexor and extensor exercises, then device complexity is reduced, but loss of time increases
Solution Approach 1:
The device combines both flexor and extensor exercise capabilities in a single machine, eliminating the need for users to switch between separate machines. The slant board's multi-position capability allows both muscle groups to be exercised sequentially without leaving the device, saving time while keeping the structure relatively simple.
3Adaptability or versatility
If advanced mechanisms are added to enable both flexor and extensor exercises, then adaptability is improved, but manufacturing cost increases
Solution Approach 1:
The adjustable fulcrum mechanism uses a simple sliding or telescoping design that allows position changes without requiring complex mechanical systems. This approach achieves adaptability for different muscle groups while keeping manufacturing costs relatively low compared to more sophisticated adjustable mechanisms.

AI summary
An exercise device that exercises both flexor and extensor muscles is provided. The exercise device includes a base having a front end, a rear end, a first side and a second side. Protruding from the rear end of the base is an anchor bar. The anchor bar may be substantially perpendicular to the base. An overhead handle bar may be pivotally connected to the top of the anchor bar by a pivot point. A stationary fulcrum may be secured to opposing sides of the base. A rotating rod is secured to the stationary fulcrum and rotates about a horizontal axis running through the rotating rod and the fulcrum. A slant board is supported by and pivots about the rotating rod.
