Solution Overview

Problem

Existing solutions for mounting electronic control screens in humid environments, such as shower or hydro massage control devices, require complex assembly systems and specific tools to create an airtight seal, increasing costs and deterring installation.

Innovation Solution

A device comprising a box inserted into a wall hole with a flat plate secured using fixing means, featuring keyhole slot fixings with elastic fittings for a snap connection and perimeter rubber for an airtight seal, allowing horizontal and vertical movements for easy mounting and dismounting without specialized tools.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If complex assembly systems and specific tools are used to create an airtight seal, then the seal quality is improved, but the device complexity and installation cost increase

Engineering Contradiction:
Improveairtight seal qualityVSAvoidassembly system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The mounting device enables the electronic control screen to perform its own sealing operation through the elastic fittings and snap connection mechanism. The elastic fittings automatically compress and seal against the wall surface when the screen is pushed into place, eliminating the need for external sealing tools or complex assembly systems while ensuring reliable airtight sealing in humid environments

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The elastic fittings change their physical state from uncompressed to compressed as the screen is mounted, automatically adjusting the sealing pressure parameter. This parameter change allows the sealing force to increase naturally during the mounting process without requiring external tools, achieving both simplicity and seal quality

Inventive Principle:
Principle #35Parameter changes

2Reliability

If complex tools are used for mounting, then the sealing reliability is improved, but the ease of operation deteriorates

Engineering Contradiction:
Improvesealing reliabilityVSAvoidmounting ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The device allows the electronic control screen to mount and seal itself through a simple pushing motion. The elastic fittings and snap connection mechanism automatically engage and seal without requiring specialized tools, making the operation as easy as placing the screen against the wall while ensuring reliable sealing

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The mounting process is segmented into two simple movements: horizontal placement and vertical pressing. This segmentation breaks down the complex sealing task into elementary actions that require no specialized tools, improving ease of operation while maintaining sealing reliability through the elastic fitting mechanism

Inventive Principle:
Principle #1Segmentation

3Strength

If traditional mounting methods are used, then the structural strength is ensured, but the manufacturing precision requirements increase

Engineering Contradiction:
Improvemounting strengthVSAvoidalignment precision
Core Design Contradiction:
StrengthVSManufacturing precision

Solution Approach 1:

The keyhole slot fixings feature an asymmetric geometry with a wide part for insertion and a narrow part for retention. This asymmetric design guides the lugs during horizontal placement and automatically secures them in the vertical position, providing both mounting strength and tolerance to alignment variations without requiring high manufacturing precision

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

Instead of requiring precise pre-alignment before mounting, the design inverts the approach by using the keyhole slot geometry to self-align and guide the lugs during installation. The wide part accepts various entry angles and the slanted inner surface guides the lugs into the correct position, reducing manufacturing precision requirements while ensuring strong mounting

Inventive Principle:
Principle #13The other way round (Inversion)
