Solution Overview

Problem

Existing illuminating glass partitions are not robust, ecological, or easy to install, as they often require complex lighting systems integrated within the glass modules, which can be aesthetically unappealing and difficult to set up.

Innovation Solution

A new illuminating glass partition design featuring a lighting system with light-emitting diodes (LEDs) positioned outside the glass modules, using a profile with a solid surface that maintains a gap between the LEDs and the glass edge, allowing for easy installation and protection of the LEDs during assembly, while maintaining a transparent appearance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the lighting system is integrated inside the glass module, then the illumination is achieved, but the installation becomes complex and the aesthetics are compromised

Engineering Contradiction:
Improveinstallation simplicityVSAvoidlighting system integration
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The lighting system is extracted from the interior of the glass module and positioned externally. The LEDs are mounted on a support structure that faces the glass edge from the outside, eliminating the need for complex internal integration while maintaining the illumination function through total internal reflection at the glass edge.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

A profile structure with a solid surface acts as an intermediary between the external LED lighting system and the glass module. This profile maintains a precise gap between the LED emitting face and the glass edge, allowing light to enter the glass while protecting the LEDs and enabling simple installation without drilling or complex integration.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Illumination intensity

If the LEDs are positioned close to the glass edge for efficient lighting, then the illumination effectiveness improves, but the LEDs become vulnerable to shocks and damage

Engineering Contradiction:
Improvelighting efficiencyVSAvoidLED protection
Core Design Contradiction:
Illumination intensityVSReliability

Solution Approach 1:

The profile with the solid surface serves as a protective intermediary between the LEDs and the glass module. It maintains an optimal gap that allows sufficient light entry for effective illumination while physically protecting the LEDs from shocks and damage during installation and operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The profile structure is designed beforehand to maintain a protective gap between the LEDs and the glass edge. This pre-established spacing cushions the LEDs against potential shocks and impacts during assembly and use, preventing damage before it can occur.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Shape

If the glass module is made transparent for aesthetic purposes, then the visual appeal improves, but the structural support and LED protection become more difficult

Engineering Contradiction:
ImprovetransparencyVSAvoidsupport structure
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The lighting system and support structure are extracted to the exterior of the transparent glass module. This allows the glass to remain fully transparent for aesthetic purposes while the external profile and solid surface provide the necessary structural support and LED protection without compromising the glass's visual clarity.

Inventive Principle:
Principle #2Taking out (Extraction)
