Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise resistance methods and apparatus lack versatility and efficient resistance adjustment mechanisms, particularly in accommodating different exercise types and user preferences, with limited control over resistance levels and feedback.
Innovation Solution
The exercise apparatus features a frame with shafts, brake drums, and sheaves connected by one-way clutch assemblies, allowing for adjustable resistance through tension in brake bands, and includes a touch-screen display for electronic resistance control and data tracking, accommodating various exercises like hip-thrust and lat-pull with separate resistance devices for each exercise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single resistance device is used for multiple exercises, then device complexity is reduced, but adaptability to different exercise types deteriorates
Solution Approach 1:
The resistance system is divided into separate resistance devices (first resistance device for hip-thrust, second resistance device for lat-pull) that can independently provide resistance for different exercises. This segmentation allows each device to be optimized for its specific exercise while maintaining overall system versatility.
Solution Approach 2:
The exercise apparatus is designed with multiple resistance devices that can accommodate various exercise types (hip-thrust, lat-pull, and others). The frame structure and resistance mechanism are universal enough to support different exercises while providing specialized resistance control for each.
2Device complexity
If manual resistance adjustment is used, then device complexity is reduced, but ease of operation deteriorates
Solution Approach 1:
The manual mechanical resistance adjustment system is replaced with an electronic control system that includes a processor and display. The processor controls the resistance devices electronically, allowing users to adjust resistance levels through the display interface rather than manual mechanical adjustments.
Solution Approach 2:
The system incorporates a display that provides feedback to users about resistance levels and exercise data. This feedback mechanism allows users to monitor and adjust resistance settings easily, improving ease of operation while maintaining electronic control.
3Adaptability or versatility
If separate resistance devices are used for each exercise, then adaptability to different exercises is improved, but device complexity increases
Solution Approach 1:
The resistance system is divided into separate resistance devices (first resistance device for hip-thrust, second resistance device for lat-pull) that can independently provide resistance for different exercises. This segmentation allows each device to be optimized for its specific exercise while maintaining overall system versatility.
4Ease of operation
If electronic control is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The manual mechanical resistance adjustment system is replaced with an electronic control system that includes a processor and display. The processor controls the resistance devices electronically, allowing users to adjust resistance levels through the display interface rather than manual mechanical adjustments.
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
This solution provides a versatile and adjustable resistance system that effectively supports multiple exercises, allowing for precise resistance control and user feedback, enhancing the workout experience by accommodating different user needs and exercise types.
Implementation Method 1
brake band segments wrapped around portions of respective left and right brake drums. Tension in the brake band segments is selectively simultaneously increased to increase resistance to rotation of both brake drums
Implementation Method 2
A first one-way clutch assembly is operatively interconnected between the first brake drum and the first sheave to constrain the first sheave and the first brake drum to rotate together in the braking direction and to allow the first sheave to rotate relative to the first brake drum in an opposite, rewind direction
Implementation Method 3
a rewind spring interconnected between the sheave and the frame to bias the sheave to rotate in a rewind direction

AI summary
An exercise apparatus includes a seat to accommodate a person in a seated position, an upper back rest to support the person's back, a foot rest to the person's feet, and a lap engaging member spanning the person's lap. A first resistance device is connected to opposite ends of the lap engaging member to resist movement of the lap engaging member away from the seat. A second resistance device is connected to a handle to resist movement of the handle from a position behind the back rest toward the back rest. A person sits on the seat and performs a combination exercise involving both: (a) a hip thrust exercise, wherein the person thrusts her hips and the lap engaging member upward and away from the seat; and (b) a lat pull down exercise, wherein the person pulls the handle from an arm's length distance behind the back support to a position more proximate the upper back support.
