Two-Piece Cane Handle With Segmented Grip And Shock Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional canes fail to simultaneously provide a reliable hand grip and impact absorption, making them uncomfortable and unreliable for elderly or disabled users.
Innovation Solution
A cane with a two-piece handle comprising a rigid body portion and a soft, resilient top portion, along with a soft and resilient tip, designed to offer increased frictional resistance and comfort through a unique configuration that absorbs impact and provides a secure grip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid handle is used, then the hand grip reliability is improved, but the impact absorption capability deteriorates
Solution Approach 1:
The handle is divided into two distinct segments: a rigid lower portion that provides structural support and grip reliability, and a soft upper portion that absorbs impact shocks. This segmentation allows each part to perform its specialized function without compromising the other.
Solution Approach 2:
The handle combines two different materials with contrasting properties - a rigid material for the lower portion and a soft, resilient material for the upper portion. This composite structure enables the handle to simultaneously provide grip reliability and impact absorption.
2Object-affected harmful factors
If a soft handle is used, then the impact absorption is improved, but the hand grip reliability deteriorates
Solution Approach 1:
The handle is divided into two distinct segments: a rigid lower portion that provides structural support and grip reliability, and a soft upper portion that absorbs impact shocks. This segmentation allows each part to perform its specialized function without compromising the other.
Solution Approach 2:
The handle combines two different materials with contrasting properties - a rigid material for the lower portion and a soft, resilient material for the upper portion. This composite structure enables the handle to simultaneously provide grip reliability and impact absorption.
3Ease of manufacture
If a single-material handle is used, then the manufacturing simplicity is improved, but the functional versatility deteriorates
Solution Approach 1:
The handle is divided into two distinct segments: a rigid lower portion that provides structural support and grip reliability, and a soft upper portion that absorbs impact shocks. This segmentation allows each part to perform its specialized function without compromising the other.
Solution Approach 2:
The handle combines two different materials with contrasting properties - a rigid material for the lower portion and a soft, resilient material for the upper portion. This composite structure enables the handle to simultaneously provide grip reliability and impact absorption.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The cane provides enhanced comfort and reliability by offering a secure hand grip and effective impact absorption, improving user stability and safety.
Implementation Method 1
The top portion is soft and resilient with respect to the bottom portion
Implementation Method 2
a cane tip which may be made of resiliently deformable material attached to a lower end of the cane shaft
Implementation Method 3
The top portion of the handle preferably comprises a surface having more frictional resistance than a surface of the body portion

AI summary
A comfort cane includes a cane shaft having an upper end and lower end thereof, and a two-piece handle affixed to the upper end of the cane shaft. The handle includes a rigid body portion substantially defining a profile of the handle in a top view of the handle, and a top portion attached to the body portion. The top portion is soft and resilient with respect to the body portion.
