Solution Overview

Problem

Shower caddies with fixed suction cups often fail to securely attach to shower walls, especially when aligned with grout lines or irregularities, and struggle to accommodate oversized toiletry bottles due to non-adjustable shelving systems.

Innovation Solution

A shelving system with adjustable shelves that can move in both vertical and lateral directions, equipped with a central support member and clamping mechanisms that securely attach to the shower head pipe and wall, and a pivotable suction cup for secure attachment to the wall, allowing for flexible placement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If suction cups are positioned in fixed locations on the shower caddy, then the structure is simple and easy to manufacture, but the suction cups may align with grout lines or irregularities causing poor sealing and insecure attachment

Engineering Contradiction:
Improveattachment securityVSAvoidattachment mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The suction cup is made pivotable relative to the shower caddy body, allowing it to dynamically adjust its position and orientation to achieve proper alignment with the wall surface and avoid grout lines, thereby improving attachment security without requiring a complex adjustable mechanism

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The attachment system is divided into separate functional components: the main caddy body and the pivotable suction cup assembly. This segmentation allows the suction cup to be independently positioned and adjusted relative to the caddy, enabling it to adapt to wall irregularities while keeping the overall structure relatively simple

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If shelves are made non-adjustable, then the structure is simpler and more stable, but oversized toiletry bottles cannot be accommodated

Engineering Contradiction:
Improveaccommodation of various item sizesVSAvoidshelving system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The shelves are designed to be slidable along the support member in both vertical and lateral directions, allowing dynamic repositioning to accommodate different bottle sizes and shapes. The shelves can be locked at various positions to maintain stability when holding items

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The shelving system is designed to handle multiple types and sizes of toiletry items through the adjustable shelf positions. The same shelf structure serves universal purposes by accommodating everything from small bottles to large oversized containers through position adjustment

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If the shower caddy is designed with fixed shelf positions, then the manufacturing precision requirements are lower, but the system cannot accommodate oversized shampoo bottles from warehouse retail stores

Engineering Contradiction:
Improveshelf position flexibilityVSAvoidshelf adjustment mechanism precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The shelves are designed with sliding capability along the support member, allowing continuous adjustment to various positions. This dynamic positioning system enables accommodation of oversized bottles without requiring extremely precise manufacturing tolerances, as the shelves can be positioned to match the actual dimensions of stored items

Inventive Principle:
Principle #15Dynamics

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 system provides secure and adjustable storage for various-sized items, preventing the shower caddy from tilting or falling, and ensuring a stable attachment to the shower wall, even with heavy or oversized toiletries.

Implementation Method 1

a resilient member can be disposed in the aperture so as to lie between an outer surface of a shower head pipe and an inner surface of the aperture when the connector is disposed around a shower head pipe

Methodology Applied
Scientific EffectElasticity: Elasticity

Implementation Method 2

a second connector device can comprise a suction cup pivotally mounted to a lower end of the central support member

Methodology Applied
Scientific EffectSuction: Suction

AI summary

A shelving system having a support member and a plurality of shelves slidably connected to the support member with a connection mechanism. The connection mechanism including a clamping mechanism moving between locked and unlocked positions, wherein in the locked position the shelf is locked to the support member and in the unlocked position the shelf can be adjusted linearly along and linearly perpendicularly to a longitudinal axis of the support member. The top of the support member includes a hinged clamp which can attach to a shower head pipe for hanging the shelving system, and the bottom of the support member includes a suction cup for further securing the shelving system to the surface of a wall.
