Adjustable Ankle Stirrup with Pivotal Holder Extender
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ankle stirrups with integrally formed ankle holders cannot accommodate legs of different sizes and lengths effectively, resulting in a decreased fixing effect due to mismatched sizes.
Innovation Solution
The ankle stirrup design includes a base, an ankle holder, a holder extender, and four combination structures with hook portions and fixing grooves, allowing for adjustable mounting angles and heights through pivotal combinations, enabling the stirrup to fit various leg sizes and lengths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the ankle holder is integrally formed as an upright holder, then the ankle holder can be mounted around the whole leg to achieve a fixing effect for the ankle, but the size of the ankle holder cannot match the size of the leg of users with different leg sizes and lengths, resulting in decreased fixing effect
Solution Approach 1:
The ankle holder is divided into multiple segments: a base, an ankle holder body, and an extensible holder. These segments can be connected through combination structures with hook portions and fixing grooves, allowing the holder to be adjusted in length and configuration to match different leg sizes and lengths while maintaining structural integrity and fixing effectiveness.
2Reliability
If the ankle holder is made adjustable to fit different leg sizes, then the fixing effect for users with different leg sizes can be improved, but the device complexity increases due to additional combination structures
Solution Approach 1:
The combination structures with hook portions and fixing grooves serve multiple functions: they connect the base to the ankle holder body, allow adjustment of the extensible holder length, and provide stable fixation when engaged. This universal connection mechanism enables the device to adapt to different user requirements while using a standardized, relatively simple structural element.

AI summary
An ankle stirrup has a base, an ankle holder, a holder extender, and four combination structures. The ankle holder is pivotally combined with the base. The holder extender is pivotally combined with the ankle holder and located over the ankle holder. The four combination structures are disposed on the base, the ankle holder, and the holder extender to combine with the base, the ankle holder, and the holder extender. The ankle stirrup can achieve a fixing effect for an ankle of a user.
