Walker Fastening Assembly Stability Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional walkers lack a secure fastening mechanism between the clamping ends and the connection part, leading to instability and potential separation of the walker's components when touched, causing loss of support and risk of falling.
Innovation Solution
A fastening assembly with a first baffle, second baffle, curved wall, and clasping component is integrated into the walker, featuring a pivot end, clasping portion, and plugs that enhance stability by engaging with the clasping component to prevent the fastening assembly from falling off, utilizing a hinge pin and clasping structure for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional fastening assembly with only clamping ends is used, then the walker can be easily disassembled for storage, but the fastening assembly may fall off when touched and the brace units will separate
Solution Approach 1:
The fastening assembly is divided into multiple functional components: a plug for insertion into the connection part, a curved wall connecting the plug to the clamping ends, and clamping components with clasp arms. This segmentation allows each part to perform its specific function while working together to provide both ease of assembly and reliable fixation.
Solution Approach 2:
The plug is inserted into a cavity within the connection part, and the clamping components are positioned within the space between the clamping ends. This nested arrangement ensures that all components are contained within the connection part structure, providing stability while maintaining a compact design that allows easy assembly and disassembly.
2Device complexity
If the fastening assembly has no additional fixing member between clamping ends, then the structure is simple, but the connection part lacks stability and may separate
Solution Approach 1:
The plug, curved wall, and clamping components are merged into a single integrated fastening assembly that functions as one unit. This merging provides enhanced stability through multiple fixed points (the plug anchored in the cavity and the clamping ends securing the brace units) while maintaining relative structural simplicity by combining these elements into a cohesive assembly designed for straightforward installation and removal.

AI summary
The present invention provides a walker including a fastening assembly. The walker has a connection part including two brace units, the fastening assembly assembled with the two brace units, and two side frames mounted to the connection part. The fastening assembly has a first baffle having a pivot end, a second baffle having a clasping portion, a curved wall having at least one plug and connecting the first baffle and the second baffle, and a clasping component pivotally mounted to the pivot end and selectively engaged with the clasping portion. The at least one plug of the fastening assembly is inserted into and fixed by the two brace units; and the clasping component is engaged with the clasping portion for further enhancing stability of the connection part and the fastening assembly to prevent the fastening assembly from falling off.
