Solution Overview

Problem

Conventional laminated panes used in display units, such as refrigerated units, often have opaque edge areas due to connecting elements like metal frames, which disrupt the view and are not aesthetically pleasing for presenting goods.

Innovation Solution

A laminated pane design featuring at least two parallel panes connected exclusively with a transparent adhesive, optionally reinforced with metal or plastic elements, allowing for a seamless, unobstructed view and enhanced stability without external frames, using a method where the adhesive is applied between panes and cured to form a strong bond.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If metal frames or connecting elements are used to connect panes, then structural stability and strength are improved, but transparency and aesthetic appearance deteriorate due to opaque edge areas

Engineering Contradiction:
Improvestructural stabilityVSAvoidtransparency
Core Design Contradiction:
StrengthVSIllumination intensity

Solution Approach 1:

The patent removes traditional metal frames and connecting elements from the pane assembly, extracting the opaque components that block light. Instead, it uses a transparent adhesive system that maintains structural integrity while preserving transparency and aesthetic appearance.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent changes the material parameter of the connecting element from opaque (metal) to transparent (adhesive). This parameter change allows the connecting function to be maintained while eliminating the visual obstruction, thus resolving the contradiction between strength and transparency.

Inventive Principle:
Principle #35Parameter changes

2Illumination intensity

If transparent adhesive is used to connect panes exclusively, then transparency and aesthetic appearance are improved, but structural strength and stability may worsen compared to metal frames

Engineering Contradiction:
ImprovetransparencyVSAvoidstructural stability
Core Design Contradiction:
Illumination intensityVSStrength

Solution Approach 1:

The patent employs a composite connection system combining transparent adhesive with reinforcement elements. The adhesive provides transparency and basic bonding, while embedded reinforcements (such as metal strips or profiles) provide additional structural strength, creating a composite solution that achieves both transparency and stability.

Inventive Principle:
Principle #40Composite materials

3Illumination intensity

If panes are connected in edge regions with transparent adhesive, then unobstructed view and aesthetic presentation are improved, but connection reliability and durability may worsen without traditional framing

Engineering Contradiction:
Improveunobstructed viewVSAvoidconnection reliability
Core Design Contradiction:
Illumination intensityVSReliability

Solution Approach 1:

The patent embeds reinforcement elements within the transparent adhesive layer, creating a nested structure where the adhesive provides the outer transparent matrix and the reinforcements are nested inside, providing hidden structural support that enhances connection reliability without compromising the unobstructed view.

Inventive Principle:
Principle #7Nested doll (Nesting)

4Illumination intensity

If no external frames or connecting elements are used, then aesthetic appearance and presentation quality are improved, but ease of manufacture and assembly may worsen

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidassembly process
Core Design Contradiction:
Illumination intensityVSEase of manufacture

Solution Approach 1:

The patent incorporates reinforcement elements and adhesive application features directly into the manufacturing process, performing preliminary actions during production. This includes pre-positioning reinforcements and applying adhesive in controlled patterns during assembly, which simplifies the overall manufacturing process despite the complex structure.

Inventive Principle:
Principle #10Preliminary action
