Telescopic Folding Walking Aid for Height Adjustment and Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing walking aids lack the ability to adjust height and fold simultaneously, making them unsuitable for individuals of varying heights and difficult to store when not in use.
Innovation Solution
A telescopic folding walking aid with a folding mechanism comprising a first and second connecting sleeve, a spring, a limiting member, a screw, a nut, and a button, allowing for adjustable height through compression springs and adjusting holes, and featuring interchangeable non-slip pads, wheels, and walker ski glides for different user needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a walking aid is designed with fixed structure, then it is simple to manufacture, but it cannot be adjusted for different heights or folded for storage
Solution Approach 1:
The walking aid is divided into multiple segments including telescopic legs with adjustable sections, a folding seat backrest, and a folding footrest. These segmented components can be independently adjusted or folded to accommodate different user needs and storage requirements, resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The walking aid incorporates dynamic elements such as telescopic legs that can extend or retract, a seat backrest that can fold forward, and a footrest that can be folded. These dynamic components allow the device to transform between different configurations (standing, sitting, storage positions), providing height adjustment and folding capabilities while maintaining a relatively simple base structure.
2Adaptability or versatility
If a walking aid includes height adjustment mechanism, then it can suit different heights, but it increases device complexity
Solution Approach 1:
The telescopic legs incorporate a dynamic extension mechanism with telescopic sections that can be adjusted to different heights. This dynamic structure allows the walking aid to adapt to various user heights while maintaining a compact form when not in use, balancing height adaptability with structural considerations.
3Volume of moving object
If a walking aid is designed to be folded, then it can be stored compactly, but it increases device complexity
Solution Approach 1:
The walking aid is segmented into foldable components including the seat backrest and footrest, which can be independently folded to reduce overall volume for storage. This segmentation allows the device to be compact when stored while maintaining structural integrity during use.
Solution Approach 2:
The seat backrest and footrest are designed with folding capabilities, allowing them to dynamically change between extended (use) and folded (storage) positions. This dynamic folding mechanism reduces the storage volume of the walking aid while maintaining a relatively simple overall structure.
