Solution Overview

Problem

Existing shower basket mounting systems struggle with angular tolerance deviations in shower corners, particularly in three-point mounting systems, leading to reduced holding power and requiring skilled assembly.

Innovation Solution

A shower basket system with a two-part base plate pivotally connected via a single pivot joint, allowing compensation for angular tolerances by pivoting the base parts around a vertical axis, ensuring secure three-point attachment without specialized skills.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a three-point mounting system is used to ensure secure attachment, then holding power is improved, but the system becomes sensitive to angular tolerance deviations in shower corners

Engineering Contradiction:
Improveholding powerVSAvoidtolerance to angular deviations
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The mounting system employs a dynamically adjustable base plate that can pivot and rotate to adapt to angular deviations in shower corners. The base plate includes a pivotable arm that can be adjusted to compensate for non-90° angles between wall surfaces, allowing the three-point mounting system to maintain optimal holding power while accommodating variations in corner geometry.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system allows for parameter changes in the mounting configuration, specifically the ability to adjust the angle and position of the base plate relative to the walls. This enables the mounting system to adapt to different angular tolerances while maintaining the three-point attachment configuration for secure holding.

Inventive Principle:
Principle #35Parameter changes

2Strength

If a three-point mounting system is used to provide sufficient storage space with increased depth, then load-bearing capacity is improved, but assembly complexity increases requiring skilled craftsmanship

Engineering Contradiction:
Improveload-bearing capacityVSAvoidassembly simplicity
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The mounting system is divided into segmented, modular components including a base plate with separate adjustable arms, mounting brackets, and adhesive elements. This segmentation allows each component to be independently positioned and adjusted, simplifying the assembly process while maintaining the three-point attachment configuration for high load-bearing capacity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The base plate incorporates self-adjusting mechanisms that allow the installer to automatically compensate for angular deviations without requiring specialized skills. The pivotable arms and adjustable mounting positions enable the system to self-align to the actual corner geometry, reducing assembly complexity while maintaining strong three-point attachment.

Inventive Principle:
Principle #25Self-service

3Volume of moving object

If the basket depth is increased to provide sufficient storage space, then storage capacity is improved, but the lever arm of the moment of force increases reducing holding power

Engineering Contradiction:
Improvestorage capacityVSAvoidholding power
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The mounting system is designed with preliminary reinforcement features including a wide base plate that distributes the moment of force over a larger area, and strategically positioned mounting points that are optimized to counteract the increased lever arm effect of deeper baskets. The adhesive strips are positioned to maximize their moment resistance before the load is applied.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system employs a counterbalancing design where the base plate extends beyond the basket depth to provide a counter-lever arm that offsets the moment of force generated by the deep basket. This creates a balanced moment system that maintains holding power despite increased storage capacity.

Inventive Principle:
Principle #8Anti-weight (Counterweight)

AI summary

A shower basket system (1) for fixing in a shower corner, comprising a container (5) in the form of a corner basket, which has two side walls (3, 4) approximately at a right angle to each other and a base (15) held by said side walls, and a base plate (7) which is composed of a first base part (10) and a second base part (11) which have adhesive surfaces (90, 91) on the rear side for self-adhesive adhesive strips (13) and coupling elements (30, 31) on the front side for fixing in each case to one of the side walls (3, 4); wherein each side wall (3, 4) has coupling receptacles (6) on the outer side for the releasable connection to the coupling elements (30, 31) of the base plate (7); characterized in that the base parts (10, 11) are connected pivotably to each other via a single rotary joint (8) with a vertical axis of rotation; and the coupling of at least one of the base parts (10, 11) and the associated side wall (3, 4) has such a play that on-site angular tolerances of a wall corner up to a predetermined maximum angular deviation from the 90° standard angle can be compensated for by corresponding pivoting of the base parts (10, 11) about the rotary joint (8).
