Solution Overview

Problem

Existing devices with touchscreens mounted in wall recesses face challenges in providing a stable and protective environment for the touchscreen while maintaining a space-saving design and minimizing exposure to environmental influences.

Innovation Solution

A device comprising a touchscreen with a self-supporting glass plate that serves as both the touch-sensitive surface and a protective layer, integrated with a computer and a housing that is attached to the back of the self-supporting plate, and sealed with a circumferential seal to prevent air and particle exchange between the wall recess and the exterior.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If the touchscreen is recessed into the wall to save space and protect it from environmental influences, then the device protrudes minimally and is protected from environmental influences, but the touchscreen requires additional supportive and protective elements to maintain structural stability

Engineering Contradiction:

Improveprotection from environmental influencesVSAvoidadditional supportive and protective elements

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent combines the protective function and structural support function into a single integrated self-supporting plate. This plate serves both as the structural element that maintains the touchscreen's position in the wall recess and as the protective barrier against environmental influences, eliminating the need for separate supportive and protective components.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The self-supporting plate performs multiple functions simultaneously: it provides structural support for the touchscreen, protects the touchscreen from environmental factors, and serves as the front surface of the device. This multi-functionality reduces overall device complexity while maintaining protection and stability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Stability of the object's composition

If a self-supporting plate is used to provide structural stability, then the touchscreen is stabilized without additional supportive elements, but the device complexity increases due to the need for a robust self-supporting structure

Engineering Contradiction:

Improvestructural stability of touchscreenVSAvoidself-supporting structure

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The self-supporting plate is made from composite materials that provide high structural strength and stability while maintaining a relatively simple and integrated structure. The use of advanced materials allows the plate to support the touchscreen effectively without requiring additional complex supportive elements.

Inventive Principle:

Principle #40Composite materials

3Volume of moving object

If the touchscreen is installed in a wall recess to achieve space-saving design, then the device occupies minimal space, but the touchscreen becomes vulnerable to environmental influences without proper sealing

Engineering Contradiction:

Improvespace occupation of deviceVSAvoidexposure to environmental influences

Core Design Contradiction:

Volume of moving objectVSObject-affected harmful factors

Solution Approach 1:

The patent employs a circumferential seal that creates an airtight barrier between the wall recess and the external environment. This seal prevents air and particles from entering the wall recess, protecting the touchscreen from environmental influences while maintaining the space-saving recessed installation.

Inventive Principle:

Principle #30Flexible shells and thin films

4Object-affected harmful factors

If additional protective layers and air gaps are introduced between the screen and touch-sensitive surface, then the touchscreen is protected from environmental influences, but the device complexity and space requirements increase

Engineering Contradiction:

Improveprotection of touchscreenVSAvoidprotective layers and air gaps

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent integrates the protective function into the self-supporting plate itself, eliminating the need for separate protective layers and air gaps. The plate's material properties and structural design provide inherent protection against environmental influences, simplifying the overall device structure.

Inventive Principle:

Principle #5Merging (Combining)
