Pivoting Abdominal Exercise Machine With Hinged Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise devices for core muscle strengthening are often uncomfortable and limited in the range of motion, leading to potential injuries and decreased effectiveness due to repetitive exercises on hard surfaces and lack of variation in movement.
Innovation Solution
A pivoting abdominal exercise machine with a hinged frame that bends with the user, supported by a stable base stand and cushioned pads or rollers, allowing for various exercises and enhanced core muscle strengthening through adjustable components and resistance mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional exercise devices are used for core muscle strengthening, then they provide stable support, but they are limited in range of motion and exercise variety
Solution Approach 1:
The frame is designed with a hinge joint that allows it to dynamically pivot and bend in response to user movement. This dynamic structure enables multiple exercise variations (crunches, sit-ups, leg raises) while maintaining stable support, resolving the contradiction between exercise versatility and structural simplicity
Solution Approach 2:
The frame is segmented into multiple sections connected by hinge joints, allowing independent movement of each section. This segmentation enables the frame to adapt to different exercise motions and user positions, providing exercise variety without requiring multiple separate devices
2Ease of operation
If exercises are performed on hard surfaces, then device structure can be simple, but comfort is poor and injury risk increases
Solution Approach 1:
Cushioned pads are strategically positioned at all user contact points (head, back, hips, knees, feet) before exercise begins. This prior cushioning eliminates discomfort and injury risk associated with hard surfaces while maintaining device structural simplicity
Solution Approach 2:
Different portions of the device have different properties - hard structural components for stability and support, while localized areas (contact surfaces) have soft cushioned properties for comfort. This local differentiation resolves the contradiction between structural simplicity and comfort
3Adaptability or versatility
If fixed-direction exercise devices are used, then structure is simple, but exercise routine variation is limited
Solution Approach 1:
The hinge joint creates a dynamic pivot mechanism that allows the frame to move in multiple directions (forward, backward, lateral) while maintaining structural simplicity. This single dynamic element enables extensive exercise routine variation without complex mechanisms
Solution Approach 2:
The pivoting frame serves multiple functions - providing support during crunches, sit-ups, leg raises, and other core exercises. This multi-functionality is achieved through a single hinge mechanism, avoiding the need for separate devices for each exercise type

AI summary
A pivoting abdominal exercise machine is used to exercise and strengthen core muscles. The machine includes a hinged frame, a plurality of back supports, and a base stand. The plurality of back supports is connected along the hinged frame. Together, the hinged frame and the plurality of back supports are used to interact with and brace portions of the user's back as the user performs an exercise. The plurality of back supports may either be cushioned pads or rollers. The base stand is mounted to the hinged frame through an elastic pivot resistor. The elastic pivot resistor allows the user to rock, tilt, or twist about the base stand. A frame-grasping assembly is mounted to the hinged frame. The frame-grasping assembly allows the user to hold onto the device and maintain stability while performing exercises.
