Solution Overview
Problem
Existing lighting systems for buildings face challenges such as complex and costly installations, aesthetic disruption, and durability issues due to permanent installations, particularly on historical buildings, and are limited by non-uniform surfaces and seasonal installation requirements.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If LED strips are permanently installed on buildings, then the lighting system can be used continuously, but the installation becomes complex and costly, and aesthetic integrity is compromised
Solution Approach 1:
The patent replaces mechanical LED strip installations with optical projection systems. Instead of physically mounting LED strips on building surfaces, the system uses projectors to cast light patterns onto buildings, eliminating the need for mechanical attachment and cable deployment while enabling continuous seasonal use
Solution Approach 2:
The system creates visual copies of lighting effects through projection. Rather than installing physical light sources on the building, the projectors generate light patterns that replicate the appearance of illuminated buildings without requiring permanent installation infrastructure
2Duration of action of stationary object
If LED strips are permanently installed on buildings, then the lighting system can be used at any time, but cable deployment becomes visible and deteriorates due to atmospheric agents
Solution Approach 1:
The patent eliminates the mechanical cable infrastructure by replacing wired LED systems with wireless projection technology. The projectors can be positioned on the ground and project light patterns onto buildings without requiring cable deployment across the building facade, avoiding exposure to atmospheric deterioration
Solution Approach 2:
The system extracts and removes the cable infrastructure from the lighting solution. By using projection technology, the harmful cables that connect LED strips are completely eliminated, leaving no visible or vulnerable electrical infrastructure on the building surfaces
3Ease of manufacture
If LED strips are installed on buildings with non-uniform surfaces, then the lighting system can be installed, but the aesthetic effect is compromised due to difficulty in homogeneous arrangement
Solution Approach 1:
The patent replaces mechanical LED strip mounting on complex surfaces with optical projection. Projectors can cast light patterns onto irregular building surfaces without requiring the surface to accommodate physical light sources, achieving homogeneous light distribution regardless of surface geometry
Solution Approach 2:
The system changes the fundamental parameter of light delivery from contact-based (LED strips mounted on surface) to distance-based (projection from ground level). This allows the light patterns to be projected onto any surface shape without being constrained by the surface's geometric irregularities
