Solution Overview

Problem

Existing shelf devices for bathrooms and showers often damage wall coatings during installation, leading to insecure and unstable mounting, and can be aesthetically unappealing.

Innovation Solution

A shelf device with a basis element extending in a horizontal plane and at least one angled peripheral web, featuring a flange that extends in a vertical plane underneath the wall coating, allowing secure and visually appealing mounting by being fastened on both sides of the wall, with options for above and below the basis element, and incorporating a run-off device for hygiene and anti-slip features.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the shelf device is fastened directly to the wall coating, then the mounting is simple, but the wall coating is damaged and the mounting becomes insecure

Engineering Contradiction:
Improvemounting simplicityVSAvoidmounting security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The flange is pre-installed on the wall structure before applying the wall coating. This preliminary action allows the shelf device to be securely fastened to the load-bearing wall while the wall coating is applied over it, protecting the coating from damage during installation and ensuring secure mounting without compromising either simplicity or reliability.

Inventive Principle:
Principle #10Preliminary action

2Object-affected harmful factors

If the shelf device is subsequently mounted onto the wall coating, then the wall coating remains intact, but the mounting becomes complex and the shelf device loses dimensional stability

Engineering Contradiction:
Improvewall coating damageVSAvoidmounting complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The flange is installed before the wall coating is applied, protecting the wall coating from damage during the mounting process. This preliminary installation eliminates the need for complex subsequent mounting operations while maintaining the integrity of the wall coating and ensuring dimensional stability of the shelf device.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If the flange is fastened on both sides of the wall, then the mounting security is improved, but the device complexity increases

Engineering Contradiction:
Improvemounting securityVSAvoidfastening complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The flange is divided into two distinct areas: a first flange area for fastening to the load-bearing wall structure, and a second flange area covered by the wall coating. This segmentation allows secure fastening on both sides while simplifying the overall process, as the wall coating itself provides protection and stabilization without requiring additional complex fastening mechanisms.

Inventive Principle:
Principle #1Segmentation
