Shower Caddy Rod Lock Assembly to Prevent Shelf Sliding and Wobble
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shower caddies are not adjustable, leading to limited weight-bearing capacity and instability, as shelves tend to slide down and rods tend to wobble due to loose connections.
Innovation Solution
A customizable shower caddy with adjustable main and secondary rods, featuring a lock assembly and barrel system that allows for secure positioning and increased weight-bearing capacity, using a combination of inserts, collars, and end caps with rubber pads for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If shelves are made adjustable along rods, then adaptability is improved, but the shelves tend to slide down and weight-bearing capacity deteriorates
Solution Approach 1:
The system transitions from fixed shelves to dynamically adjustable shelves that can be positioned at multiple locations along the rods. The adjustment mechanism allows users to move shelves up and down while maintaining secure attachment through engagement features that prevent sliding during use.
Solution Approach 2:
An intermediary adjustment mechanism is introduced between the shelf and rod. This mechanism includes engagement features such as teeth, notches, or clamps that mediate the connection, allowing both adjustability and secure attachment to prevent sliding.
2Ease of operation
If rods are made telescopic for compact storage, then ease of operation is improved, but the rods become loose and wobble
Solution Approach 1:
The rod system is segmented into multiple telescopic sections that can be compressed for storage and extended for use. Each section maintains structural integrity through rigid connection features that prevent wobbling when the rods are deployed.
Solution Approach 2:
The physical state of the rod system changes between compressed and extended configurations. When extended, the rods achieve sufficient rigidity to support shelves without wobbling, while maintaining compactness when compressed for storage.
3Ease of operation
If tension poles are used for installation, then ease of operation is improved, but the rods become disconnected when moved
Solution Approach 1:
The rods are pre-configured with connection features such as interlocking mechanisms, engagement protrusions, or locking features that ensure secure attachment before movement occurs. This preliminary preparation prevents disconnection during subsequent handling and installation.
Solution Approach 2:
The design incorporates built-in protection against accidental disconnection through redundant connection features or friction-fit mechanisms that cushion against movement-induced separation during installation and repositioning.

AI summary
There is provided an endcap, connector, sleeve, and rod system lock designs that can be used to form a customizable shower caddy. The endcap can freely spin without axial movement. The connectors can support product holders at different positions along an extendable rod system. The sleeve can securely connect two rods together. The rod system lock provides a more secure connection between rods of the rod system to easily and reliably lock the rods to their desired combined length.
