Adjustable Tilt Table Mechanism for Ankle Range Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foot-pedaling exercise apparatuses fail to allow users to adjust the movable range of ankle joints effectively, making it difficult for users to perform foot-pedaling exercises with appropriate joint settings.
Innovation Solution
A foot-pedaling exercise apparatus with a crank, link, and tilt table system, where the tilt table is adjustable in inclination angle and position, and equipped with a sliding wheel that moves on an inclined surface, allowing for customizable ankle joint movement ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed pedal mechanism is used, then the structure is simple, but the movable range of ankle joints cannot be adjusted
Solution Approach 1:
The patent introduces a movable tilt table that can be adjusted to different inclination angles and positions, transforming the static pedal mechanism into a dynamic system. This allows the ankle joint movable range to be adjusted by changing the tilt table's angle and position, resolving the contradiction between simplicity and adaptability.
Solution Approach 2:
The patent changes the inclination angle parameter of the tilt table to control the ankle joint movable range. By adjusting this geometric parameter, the system achieves different exercise intensities and joint ranges without complex mechanical modifications, balancing simplicity and versatility.
2Adaptability or versatility
If the tilt table is made movable in front-rear direction, then the ankle joint range is adjustable, but the device complexity increases
Solution Approach 1:
The tilt table is designed to be movable in the front-rear direction in addition to being tiltable, creating a dynamic adjustment mechanism. This allows flexible control of the ankle joint range by combining positional and angular adjustments, achieving high adaptability with relatively simple mechanical means.
3Productivity
If different tilt tables with different inclination angles are replaceable, then the exercise effectiveness is improved, but the device complexity and cost increase
Solution Approach 1:
Instead of replacing multiple static tilt tables, the patent implements a single tilt table with dynamic angle adjustment capability. This eliminates the need for multiple components while achieving the same exercise effectiveness, reducing device complexity and cost.
Solution Approach 2:
The tilt table is designed to perform multiple functions by adjusting its inclination angle to different values, replacing the need for multiple specialized tables. This multi-functional design achieves high exercise effectiveness while maintaining simple device structure.
