Bed Wheel Locking Mechanism with Lateral Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Beds with wheels and locking mechanisms are difficult to operate when the bed frame is in a low position, as the actuating means for blocking or releasing the wheels are hard to reach, making it challenging for users to easily lock or unlock the bed in such configurations.
Innovation Solution
The actuating means for blocking or releasing the wheels are arranged at the level of the wheels, allowing for easy operation even when the bed frame is in a low position, and are designed with restoring mechanisms and mechanical linkages that facilitate easy access and operation, such as pedals or levers that can be actuated with the foot, with spring-loaded components and linkage systems to return to their initial positions for consistent accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the bed frame is lowered to its lowest position, then the risk of falling out of bed is reduced, but the actuating means for the blocking means becomes extremely difficult to reach
Solution Approach 1:
The actuating means are relocated from a vertical arrangement (above the wheels) to a horizontal arrangement (at the level of the wheels, laterally offset from the bed frame). This dimensional change allows the actuating means to remain accessible from the side even when the bed frame is in its lowest position, resolving the contradiction between safety (low bed position) and operability (accessibility of actuating means).
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
This design ensures that the actuating means can be comfortably reached and easily operated, even when the bed frame is lowered, enhancing user convenience and safety by simplifying the process of locking or unlocking the wheels without requiring users to search for or strain to access the actuating mechanisms.
Implementation Method 1
The restoring means are designed to move the actuating means from the first deflected position into the starting position
