Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a light source unit is designed solely for optical wireless power transmission, then power transmission efficiency is improved, but lighting functionality is lost
Solution Approach 1:
The light source unit is designed to perform multiple functions: optical wireless power transmission and lighting. The laser light source can emit both power feed light (for photovoltaic power generation) and lighting light (for illumination), allowing a single device to replace both a power transmission system and a lighting fixture, thereby resolving the contradiction between specialized power transmission efficiency and versatile functionality
2Adaptability or versatility
If separate lighting fixtures are added to provide illumination, then lighting functionality is improved, but device complexity increases
Solution Approach 1:
The patent combines the power feed light emission function and lighting light emission function into a single light source unit. By merging these two previously separate functions into one device, the system eliminates the need for additional separate lighting fixtures, thereby reducing overall system complexity while maintaining both power transmission and lighting capabilities
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables both optical wireless power transmission and lighting, providing flexible control over light distribution and direction, allowing for simultaneous power generation and illumination without additional fixtures.
Implementation Method 1
a photoelectric transducer having the ability to generate photovoltaic power. The photoelectric transducer generates the photovoltaic power when receiving power feed light emerging from the light source unit
Implementation Method 2
The light source unit may cause the power feed light and light for lighting for lighting up a target space to emerge from the light source unit itself
Data Source
AI summary
A light system includes a light source unit including a laser light source, and a photoelectric transducer having the ability to generate photovoltaic power. The photoelectric transducer generates the photovoltaic power when receiving power feed light emerging from the light source unit. The light source unit may cause the power feed light and light for lighting for lighting up a target space to emerge from the light source unit itself. The power feed light is to be incident on the photoelectric transducer.
