Compact Shower Carrier Elevating Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shower carriers face challenges in maximizing space utilization and up-and-down displacement due to the limitations of their elevating mechanisms, which often require larger fixing parts and motors, leading to inefficient use of space and reduced mobility.
Innovation Solution
The senior-friendly shower carrier employs a dual elevating module system with motors positioned between the fixing and moving parts, allowing for compact housing design and enhanced up-and-down displacement, along with adjustable headrests and safety guides for improved patient comfort and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the motor is positioned adjacent to the fixing part to drive the elevating mechanism, then the motor can effectively transmit power to elevate the bed, but the length of the fixing part must be larger than the motor length, creating empty space that cannot be used
Solution Approach 1:
The motor is positioned inside the hollow cylindrical fixing part, allowing the motor to be nested within the structural component. This eliminates the empty space problem while maintaining power transmission capability through the hollow shaft configuration.
Solution Approach 2:
The fixing part is designed as a hollow cylinder that extends vertically, allowing the motor to be positioned at a different vertical level (inside the hollow space) rather than adjacent horizontally. This dimensional rearrangement eliminates wasted space while preserving mechanical function.
2Length of moving object
If the length of the fixing part is increased to enlarge the up-and-down displacement, then the bed can be elevated higher, but the overall device size increases disadvantageously
Solution Approach 1:
The elevating system is divided into multiple segments: the hollow fixing part, the moving part with screw thread engagement, and the bed platform. This segmentation allows the displacement function to be achieved through the interaction of components rather than a single long fixing part, reducing the overall stationary structure length.
Solution Approach 2:
The screw thread mechanism acts as an intermediary that converts rotational motion of the motor into linear displacement of the bed. This allows significant up-and-down displacement to be achieved within a compact fixing part length by utilizing the mechanical advantage of the screw thread.
