Rotating Cane Rubber Tip Wear Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional canes with adjustable length do not effectively address the issue of premature wear on rubber tips, leading to frequent replacements and ecological concerns.
Innovation Solution
A cane design featuring a rotating mechanism that allows the rubber tip to be rotated in steps, extending its usable life by shifting wear to new areas, thereby delaying the need for replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the rubber tip is fixed in one position, then the cane structure is simple, but the rubber tip wears out quickly at the contact point
Solution Approach 1:
The rubber tip is made rotatable relative to the cane body through a bearing mechanism, transforming it from a static component to a dynamic one. This allows the rubber tip to rotate and distribute wear across its entire circumference, extending its service life while maintaining structural simplicity through standardized mechanical components
2Duration of action of moving object
If the rubber tip is made rotatable to extend its life, then the rubber tip service life is extended, but the cane structure becomes more complex
Solution Approach 1:
The bearing mechanism is nested within the cane body structure, with the rubber tip rotating inside a housing that contains the bearing. This nested arrangement integrates the rotation mechanism into the existing cane structure without adding significant external complexity, while still achieving the goal of extending rubber tip service life through rotation

AI summary
A cane that can efficiently use a rubber tip (60) is provided from the aspect of ecology. The cane comprises a grip part (10) located at the upper end of a first cane body (20), the rubber tip (60) located at the lower end of the first cane body (20), and a button (52) and holes (36a-36d) for rotating the grip part (10) and rubber tip (60) in four steps, wherein the button (52) and holes (36a-36d) also serve as a fixing part for fixing the grip part (10) and rubber tip (60) after those have been rotated.
