Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing glazings, particularly marine windows, are prone to damage and breakage under high mechanical loads from waves, winds, or squalls, posing a safety risk to passengers and crew.

Innovation Solution

A high-strength glazing laminate comprising outer and inner high-strength glass plies with a layered functional block, such as a solar protection layer, positioned between the plies to absorb mechanical stress and protect the functional block, using strengthened glass and adhesive layers to manage stress distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a functional block (e.g., solar protection layer) is integrated into the glazing laminate, then additional functions (solar protection, electrical circuits, antenna) are provided, but the functional block is exposed to high mechanical stress and may suffer damage or cracks

Engineering Contradiction:

Improveadditional functionsVSAvoiddamage resistance

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces a neutral layer as an intermediary element between the functional block and the high-strength glass plies. This neutral layer acts as a stress-absorbing mediator that protects the functional block from mechanical stress while allowing the glazing to maintain its structural integrity and additional functions

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates a composite laminate structure combining high-strength glass plies, functional blocks, and neutral layers. This composite construction allows each layer to perform its specific function while collectively providing both structural strength and protection against mechanical damage

Inventive Principle:

Principle #40Composite materials

2Strength

If the functional block is positioned to withstand high mechanical stress, then durability under load is improved, but the functional block may still suffer from cracks and damage due to excessive stress

Engineering Contradiction:

Improvestress resistanceVSAvoiddamage free operation

Core Design Contradiction:

StrengthVSReliability

Solution Approach 1:

The neutral layer is positioned in advance between the functional block and the glass plies to provide cushioning protection before mechanical stress is applied. This pre-positioned protective layer absorbs and distributes stress, preventing cracks and damage to the functional block during operation

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

3Strength

If high strength glass plies are used to withstand mechanical loads, then strength and durability are improved, but the functional block between the plies is still vulnerable to mechanical stress from external loads

Engineering Contradiction:

Improveload bearing capacityVSAvoidmechanical stress on functional block

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The neutral layer serves as a protective intermediary that intercepts and absorbs mechanical stress before it reaches the functional block. This allows the high-strength glass plies to bear external loads while the neutral layer shields the functional block from harmful stress concentrations

Inventive Principle:

Principle #24Intermediary (Mediator)
