Motor-Driven Dual Shaft Exercising Device for Limb Rehabilitation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current exercising devices for therapeutic rehabilitation lack a comprehensive and efficient mechanism to engage both limbs of a user in a coordinated exercise, limiting the effectiveness of the workout and user interaction.
Innovation Solution
A device comprising a housing with a motor-driven shaft system, where each shaft is coupled to pedals that allow for simultaneous foot and hand positioning, enabling the motor to rotate the limbs in conjunction with the shafts, along with a microprocessor-controlled interface for customizable exercise settings and feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a motor-driven shaft system with pedals is used to engage both limbs simultaneously, then the effectiveness of the workout and user interaction is improved, but the device complexity increases
Solution Approach 1:
The device is divided into separate modular components including a motor assembly, dual shafts, pedals, and a control system. Each shaft-pedal assembly can be independently adjusted and positioned, allowing the complex function of engaging both limbs to be achieved through simpler, modular segments rather than a single complex mechanism.
Solution Approach 2:
The motor-driven shaft system serves multiple functions: it simultaneously engages both upper and lower limbs through the dual shaft and pedal configuration, provides customizable exercise resistance through the microprocessor-controlled motor, and enables various exercise modes by adjusting pedal positions. This multi-functionality consolidates what would otherwise require multiple separate mechanisms into a single integrated system.
2Adaptability or versatility
If pedals are made selectively couplable to shafts for foot and hand positioning, then the adaptability for different users and exercises is improved, but the ease of operation deteriorates
Solution Approach 1:
The pedal-to-shaft coupling mechanism appears to be designed for user-friendly attachment and detachment without requiring tools or complex procedures. The selective couplability allows users to independently position and secure their own feet and hands on the pedals, enabling self-adjustment for different body sizes and exercise preferences without operator intervention.
3Productivity
If the motor is configured to rotate shafts to compel limb rotation for exercise, then the productivity of the exercise is improved, but the use of energy increases
Solution Approach 1:
The motor operates in periodic cycles, rotating the shafts through controlled intervals to compel limb rotation for exercise. The microprocessor control system manages the motor's operation in discrete exercise phases rather than continuous operation, allowing energy-efficient intermittent operation while maintaining effective exercise productivity through structured periodic motion cycles.
