Walker Safety Strap With Breakaway Buckle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inexperienced users of walkers often push the device too far forward, leading to balance issues and increased risk of slips and falls, necessitating a safety strap that prevents excessive forward movement and provides stability without being used as a seat or support.
Innovation Solution
A walker safety strap device featuring a bungee-like elastic strap with C-shaped hooks at opposing ends and a breakaway buckle in the middle, which secures to the walker and adjusts to the user's size, preventing the strap from being used as a seat and ensuring the user remains within the walker's stability circle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a walker is designed to provide stability, then the walker structure becomes more robust, but the device becomes more difficult to maneuver and control
Solution Approach 1:
The patent introduces a safety strap as an intermediary device that connects the user to the walker. This strap acts as a mediator that provides stability guidance without requiring changes to the walker's structural robustness, thus maintaining ease of operation while improving stability.
Solution Approach 2:
The safety strap uses elastic material with specific physical parameters (elasticity, length) to provide dynamic stability. The elastic properties allow the strap to adapt to user movement while maintaining the walker's stability boundary, avoiding the need for a more robust and cumbersome walker structure.
2Reliability
If a safety strap is added to prevent excessive forward movement, then user stability is improved, but the device complexity increases
Solution Approach 1:
The safety strap device is segmented into distinct functional components: elastic strap body, C-shaped hooks for attachment, and breakaway buckles for safety. This segmentation allows each component to perform its specific function efficiently, improving reliability without unnecessarily increasing overall device complexity.
Solution Approach 2:
The safety strap serves multiple functions simultaneously: it provides stability guidance, prevents excessive forward movement, acts as a visual marker for proper stance, and includes breakaway buckles to prevent injury. This multi-functionality improves reliability while avoiding the need for multiple separate devices.
3Adaptability or versatility
If the strap is made elastic and adjustable, then adaptability to different users is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The strap uses elastic material with inherent stretch and recovery properties that provide adaptability to different users without requiring precise manufacturing of specific dimensions. The elastic deformation naturally adjusts to various body types and walker sizes, reducing manufacturing precision requirements while maintaining versatility.
Solution Approach 2:
The strap's elastic properties allow it to dynamically adjust its effective length and tension based on user needs. This dynamic adaptability replaces the need for multiple fixed-size straps or complex adjustment mechanisms, thereby reducing manufacturing precision requirements while maintaining high versatility.
4Object-affected harmful factors
If a breakaway buckle is included to prevent injury, then safety is improved, but the strap cannot be used as a seat or support
Solution Approach 1:
The breakaway buckle, which prevents the strap from being used as a seat, is designed to break under excessive pressure. This harmful factor (inability to sit on the strap) is converted into a beneficial safety feature that prevents injury. The buckle's breaking mechanism protects users from potential harm while maintaining the strap's intended safety function.
Solution Approach 2:
The breakaway buckle is designed to fail safely under excessive load rather than permanently deform or create a seat. This disposable-like approach ensures that the strap cannot be misused as a seat, prioritizing user safety over versatility in this specific application.
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 strap device provides stability and balance guidance by maintaining the user within the walker's defined area, reducing the risk of falls by preventing excessive forward movement and ensuring proper stance, while the breakaway buckle prevents injury from excessive pressure.

AI summary
The present invention relates to a novel walker safety strap device. The device is a multipurpose strap that will assist a user in using a walker. The strap device functions as a bungee cord that will stretch from one side of the walker to the other, thereby providing the user with instruction for proper stance, balance, and distance from the walker. The walker safety strap device comprises a body component with a C-shaped hook at opposing ends which secure to the walker and a breakaway buckle in the middle. Generally, the strap device is elastic and adjustable based on the size of the user and/or walker to ensure that the strap device keeps the user inside the one-foot circle created by the walker during use.
