Tiltable Crank Paddling Simulator for Guided Torso Twist
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing apparatuses for paddling simulation fail to provide a controlled and guided motion that effectively engages the user's torso twisting and leg movements, resulting in uncontrolled cyclic motions.
Innovation Solution
A gymnastic apparatus with a frame, adjustable seat, footrest, and a kinematic mechanism comprising cranks or a bar assembly that simulates paddling motion, allowing for controlled torso twisting and leg engagement, with adjustable angles and resistance settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing paddling simulation apparatuses are used, then the user can simulate paddling motion, but the motion is uncontrolled and cyclic rather than guided and controlled
Solution Approach 1:
The patent applies dynamics by making the support member tiltable and adjustable, allowing the plane of crankshaft rotation to be dynamically changed. This enables the apparatus to adapt to different paddling styles and user needs while maintaining controlled motion through the kinematic mechanism. The adjustable configuration allows transition between different exercise modes while preserving the controlled guided motion characteristic.
2Adaptability or versatility
If arm ergometers are used, then arm training is provided, but torso twisting motion is not simulated
Solution Approach 1:
The patent merges arm training and torso twisting functions into a single integrated apparatus. The kinematic mechanism combines the crankshaft rotation (for arm movement) with the tiltable support member (for torso twisting), creating a unified exercise system that engages multiple upper body muscle groups simultaneously without requiring separate equipment.
Solution Approach 2:
The apparatus achieves multi-functionality by enabling both arm ergometer-style training and torso twisting exercises through its adjustable kinematic mechanism. The same basic structure can accommodate different exercise modes by adjusting the support member angle and configuration, making it a universal training device for upper body conditioning.
3Adaptability or versatility
If torso twisting equipment is used, then torso twisting is simulated, but arm training is not provided
Solution Approach 1:
The patent merges torso twisting and arm training functions into a single integrated apparatus. The kinematic mechanism combines the crankshaft rotation (for arm movement) with the tiltable support member (for torso twisting), creating a unified exercise system that engages multiple upper body muscle groups simultaneously without requiring separate equipment.
4Reliability
If the kinematic mechanism with adjustable support member is used, then controlled and realistic paddling simulation is achieved, but the device complexity increases
Solution Approach 1:
The patent applies dynamics by making the support member tiltable and adjustable, allowing the plane of crankshaft rotation to be dynamically changed. This enables the apparatus to adapt to different paddling styles and user needs while maintaining controlled motion through the kinematic mechanism. The adjustable configuration allows transition between different exercise modes while preserving the controlled guided motion characteristic.
