Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If complex 3-D models are used for lighting design, then lighting accuracy can be improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent uses augmented reality to create virtual copies of lighting fixtures that are overlaid onto the real physical space. Instead of building complex 3-D models of the entire environment, the system places simplified virtual lighting fixture models into the actual space viewed through the AR device, allowing accurate lighting simulation without the complexity of full environmental modeling
Solution Approach 2:
The AR device serves as an intermediary between the physical space and the virtual lighting models. It captures the real environment through its camera and superimposes virtual lighting fixtures onto the live feed, mediating between the simple virtual objects and the complex real-world geometry without requiring full 3-D reconstruction
2Measurement precision
If complex 3-D models are used for lighting design, then lighting accuracy can be improved, but ease of operation deteriorates
Solution Approach 1:
The system performs automatic functions without requiring user intervention in complex modeling tasks. The AR device automatically captures the physical space, places virtual lighting fixtures, and simulates lighting patterns based on photometric data, eliminating the need for users to manually create or adjust complex 3-D models
Solution Approach 2:
Virtual copies of lighting fixtures are placed directly into the AR view of the physical space, allowing users to visualize lighting effects without dealing with complex modeling operations. The system handles all the computational complexity of rendering and lighting simulation automatically
3Measurement precision
If 3-D models are used for lighting estimation, then lighting pattern accuracy can be improved, but loss of time increases
Solution Approach 1:
Photometric data for lighting fixtures is pre-calculated and stored in the system. When a virtual lighting fixture is placed in the AR environment, the lighting patterns are immediately rendered using this pre-prepared data, eliminating the need to perform complex lighting calculations in real-time during the design process
Solution Approach 2:
The patent replaces the traditional mechanical process of creating physical lighting mockups or detailed 3-D models with an optical/digital approach using augmented reality. The AR device directly renders virtual lighting effects onto the captured image, substituting time-consuming physical or computational processes with instant graphical overlay

AI summary
An augmented reality-based lighting design method includes displaying, by an augmented reality device, a real-time image of a target physical area on a display screen. The method further includes displaying, by the augmented reality device, a lighting fixture 3-D model on the display screen in response to a user input, where the lighting fixture 3-D model is overlaid on the real-time image of the target physical area. The method also includes displaying, by the augmented reality device, a lighting pattern on the display screen overlaid on the real-time image of the target physical area, wherein the lighting pattern is generated based on at least photometric data associated with the lighting fixture 3-D model.
