One-Handed Rolling Cane with Multi-Point Base
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of assistive walking devices that provide intermediate support, as single point canes offer insufficient support while two-handed walkers are unwieldy and burdensome for those who do not require substantial assistance, leading to decreased muscle strength, poor posture, and balance issues.
Innovation Solution
A one-handed rolling cane with four points of contact, designed to increase the base of support and balance, featuring a centrally placed handgrip for stability and control, and an efficiently accessible storage compartment, allowing for more fluid motion and reduced energy expenditure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single point cane is used, then the device is simple and easy to operate, but it provides insufficient support and balance
Solution Approach 1:
The base of the cane is segmented into multiple contact points (three or four gliders/wheels) instead of a single point, creating a multi-point support system that increases stability while maintaining the simplicity of a cane structure
Solution Approach 2:
The support system transitions from a single vertical point to a distributed planar arrangement of multiple contact points, adding spatial dimensionality to the base of support and significantly improving balance capabilities
2Reliability
If a two handed walker is used, then substantial support and balance is provided, but the device becomes unwieldy and burdensome
Solution Approach 1:
The device extracts only the essential support function from a full walker by using a single handgrip and lightweight frame, removing unnecessary bulk and complexity while retaining the beneficial multi-point contact base for stability
Solution Approach 2:
The cane incorporates rolling elements (wheels) and gliding surfaces that enable dynamic, fluid motion compared to static walker feet, allowing easier propulsion and maneuverability with one hand
3Reliability
If a two handed walker is used when not needed, then substantial support is provided, but it leads to decreased large muscle strength, poor posture, and loss in balance and maneuverability
Solution Approach 1:
The device provides localized support exactly where needed (through the handgrip and base of support) without the excessive support of a full walker, allowing users to maintain natural posture and muscle engagement while receiving appropriate assistance
