Adaptive Pivoting Tip Assembly for Walking Aids
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional walking aids with rubber tips often cause users to fall due to sliding when held at an angle, especially on slick surfaces, as they fail to maintain adherence to the floor and provide adequate shock absorption when inclined.
Innovation Solution
A shock absorbing and pivoting tip assembly is integrated into walking aids, featuring a bendable spring or elastic material sandwiched between upper and lower portions, allowing the tip to dynamically pivot and maintain a planar relationship with the floor regardless of the aid's angle, ensuring stability and shock absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional rubber tip is used on a walking aid, then the tip can provide stable engagement with the floor when held vertically, but the tip slides out and causes falling when the walking aid is held at an angle
Solution Approach 1:
The tip assembly incorporates a pivoting mechanism that allows the tip to dynamically adjust its orientation. The connecting rod and pivot point enable the tip to automatically reorient itself to maintain planar contact with the floor surface, transforming the static rubber tip into a dynamic system that adapts to various holding angles while maintaining stable engagement
Solution Approach 2:
The tip assembly is divided into separate functional components: a lower portion with floor-contacting element, a connecting rod, an upper portion, and a pivot point. This segmentation allows each component to perform its specific function - the lower portion provides floor engagement, the connecting rod transmits force, and the pivot enables angular adjustment, collectively solving the contradiction between stability and adaptability
2Object-affected harmful factors
If a rubber tip is used without shock absorption, then the structure remains simple, but impact forces cause injury to the user
Solution Approach 1:
A shock absorber is integrated into the tip assembly to provide impact mitigation before the force reaches the user's hand. This beforehand cushioning approach absorbs shock during impact events, reducing harmful forces transmitted to the user while maintaining a relatively simple overall structure through the use of a single integrated assembly
3Object-affected harmful factors
If shock absorbing devices are added to walking aids, then impact absorption is improved, but the devices only absorb vertical impact and do not provide pivoting capability
Solution Approach 1:
The invention merges two previously separate functions into a single integrated tip assembly: shock absorption and pivoting capability. The shock absorber is incorporated within the pivoting mechanism, allowing both functions to operate simultaneously. This merging eliminates the need for separate shock absorbing accessories and provides a unified solution that addresses both impact protection and angular adaptability

AI summary
An adaptive ambulatory support includes a shock absorbing and pivoting tip assembly attached to the staff of a walking aid, such as a cane, crutch or walker. The shock absorbing and pivoting tip assembly includes a shock absorber sandwiched between a lower portion and an upper portion. The shock absorber may be a bendable spring or elastic material. The tip assembly enables the shaft of the walking aid to dynamically pivot without the loss of adherence of the lower portion to the floor surface and simultaneous provides the adaptive shock absorbing capability in any angle during ambulation.
