Solution Overview

Problem

Existing lighting systems for staircases lack an aesthetically appealing and easily integratable solution for indirect or direct lighting of steps, particularly in tiled structures, with limited options for flexible light direction and maintenance.

Innovation Solution

A lighting system featuring an elongated profile with a base leg, decorative leg, fastening leg, and a lens cover, made from corrosion-resistant materials like aluminum or stainless steel, allowing for easy integration during tile laying, with adjustable light direction and accessible LED strips for maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If LED strips are glued under floor panels for indirect or direct lighting of steps, then lighting functionality is achieved, but integration complexity and aesthetic appeal are compromised

Engineering Contradiction:
Improveintegration easeVSAvoidintegration complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The lighting system is divided into separate functional components: an extruded profile structure that integrates with the staircase, a lens cover that directs light, and LED strips that provide illumination. This segmentation allows each component to be optimized independently while simplifying overall integration during staircase construction

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The extruded profile serves multiple functions simultaneously: it provides structural support for the lighting system, integrates with the tiled staircase structure, houses the LED strips, and works with the lens cover to direct light. This multi-functionality reduces the number of separate components needed and simplifies integration

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If traditional lighting systems are installed on staircases, then lighting is provided, but aesthetic appeal and visual attractiveness are limited

Engineering Contradiction:
Improveaesthetic appealVSAvoidsystem design
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The lens cover is designed with specific optical properties to direct light in desired patterns (indirect or direct lighting). The extruded profile is made from materials like aluminum or stainless steel that provide both structural integrity and visual appeal. These localized quality enhancements improve aesthetic appeal without requiring complete system redesign

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The extruded profile features an asymmetric cross-section with a base leg, decorative leg, and fastening leg, each serving specific functions. The decorative leg provides visual appeal while the fastening leg enables secure installation. This asymmetric design allows optimization of both aesthetics and installation ease

Inventive Principle:
Principle #4Asymmetry

3Stability of the object's composition

If lighting systems are integrated into tiled structures, then aesthetic integration is achieved, but maintenance accessibility and flexibility are reduced

Engineering Contradiction:
Improveintegration stabilityVSAvoidmaintenance accessibility
Core Design Contradiction:
Stability of the object's compositionVSEase of repair

Solution Approach 1:

The lighting system is segmented into removable components, particularly the lens cover and LED strip assembly. The lens cover can be detached from the extruded profile to provide access to the LED strips for maintenance or replacement, while the profile remains permanently integrated into the staircase structure. This segmentation maintains integration stability while enabling maintenance accessibility

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system incorporates dynamic accessibility through the removable lens cover design. During normal operation, the system maintains a stable integrated appearance. During maintenance, the lens cover can be removed to access the LED strips, providing dynamic flexibility without compromising the permanent integration of the profile structure

Inventive Principle:
Principle #15Dynamics

4Ease of manufacture

If fixed lighting systems are installed, then installation simplicity is achieved, but light direction flexibility and adaptability are limited

Engineering Contradiction:
Improveinstallation simplicityVSAvoidlight direction flexibility
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The lens cover is designed to be removable and replaceable, allowing the light direction to be dynamically adjusted. Different lens covers with different optical properties can be used to achieve indirect lighting, direct lighting, or a combination, providing adaptability while maintaining simple installation through the standardized extruded profile interface

Inventive Principle:
Principle #15Dynamics

AI summary

The lighting system (1) has an elongated profile (2) having a base leg (6) and a fastening leg (9). A decorative leg (7) is protruded from one free end of the base leg and is formed with a visible decorative surface (8) at outer surface in intended mounted state. The decorative leg is arranged above other free end of the base leg. A lighting unit (3) is arranged within the base legs and is secured or fastened to a receiving space defined between the decorative and fastening legs. The elongated tinted windshield coverings (4,5) are defined at the elongated profile.
