Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise devices for core muscle training are often bulky, expensive, require specific operation techniques, and lack versatility in resistance levels, posing risks of injury and failing to accommodate users with varying fitness levels or rehabilitation needs.
Innovation Solution
A portable exercise device with a frame and adjustable resistance system that provides a tangential force, allowing users to maintain correct posture, adjust resistance, and exercise specific muscle groups through a range of motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional exercise devices like rowing machines are used for core muscle training, then effective muscle development is achieved, but the device becomes expensive and occupies large space
Solution Approach 1:
The patent extracts the essential core muscle training function from traditional bulky exercise devices. The frame structure with resistance member creates a minimal space exercise system that delivers core training effectiveness without requiring large equipment footprint, separating the essential function from the unnecessary bulk.
Solution Approach 2:
The patent creates a simplified copy of core training mechanics using a basic frame and resistance member system. Instead of replicating complex rowing machine mechanisms, it captures the essential resistance-based core engagement principle in a compact form that maintains training effectiveness while reducing space requirements.
2Reliability
If exercise devices operate within certain resistance limits, then safety is maintained, but versatility for different fitness levels is reduced
Solution Approach 1:
The patent implements dynamic resistance adjustment through the resistance member system that can be repositioned along the frame. This allows the resistance characteristics to change based on user needs and fitness levels, transforming a static resistance system into a dynamic one that adapts to different users while maintaining safety through controlled movement ranges.
Solution Approach 2:
The patent enables parameter changes in resistance levels by allowing the resistance member to be positioned at different locations on the frame structure. This simple parameter adjustment mechanism provides versatility for different fitness levels and rehabilitation stages without compromising safety, as the resistance force can be modified while maintaining the same safe exercise framework.
3Ease of operation
If users are not instructed on proper positioning, then ease of use is improved, but risk of injury increases
Solution Approach 1:
The patent incorporates preliminary safety measures through the frame design that includes positioning guides and structural features that naturally encourage correct posture. The aperture and frame geometry are designed to predispose users toward proper positioning before exercise begins, reducing injury risk while maintaining ease of use through intuitive alignment.
4Productivity
If high intensity exercise is provided, then muscle development speed is increased, but risk of injury recurrence is increased for rehabilitation users
Solution Approach 1:
The patent creates a dynamic exercise intensity system where the resistance member can be repositioned to provide progressive overload. Rehabilitation users can start with lower resistance positions and gradually progress to more intensive positions as they heal, allowing muscle development speed to increase over time while controlling injury recurrence risk through staged intensity progression.
