Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical power supply converters face limitations in increasing output power without enlarging the light receiving element, as the number of optical fiber cables is restricted by the size of the light receiving element, leading to potential damage and increased manufacturing costs.
Innovation Solution
The optical power supply converter employs a reflecting section with a concave reflecting mirror having a partially concave surface of an ellipsoid of revolution, allowing light from multiple optical fiber cables to be reflected and focused onto a shared light receiving element without increasing its size, using the properties of an ellipse to distribute light input efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the size of the light receiving element is increased to accommodate more optical fiber cables, then the output power can be increased, but the manufacturing cost increases and the device complexity increases
Solution Approach 1:
The patent transitions from a planar arrangement of optical fiber cables to a three-dimensional configuration using a concave reflecting mirror. The mirror focuses light from multiple cables at different spatial positions onto a single light receiving element, effectively utilizing vertical and radial dimensions to increase power input without expanding the footprint of the receiving element.
Solution Approach 2:
The concave reflecting mirror acts as an intermediary component that redirects and concentrates light from multiple optical fiber cables onto the light receiving element. This mediator enables multiple light sources to be combined effectively without requiring the receiving element to be larger or more complex.
2Power
If the number of optical fiber cables is increased to increase output power, then the optical input can be increased, but the light receiving element may be damaged by excessive light concentration
Solution Approach 1:
The concave reflecting mirror is designed with specific focal properties that distribute light intensity across different regions of the light receiving element. By optimizing the mirror's curvature and position, the patent ensures that light from multiple cables is concentrated in a controlled manner that matches the receiving element's sensitive areas, preventing localized overheating or damage.
Solution Approach 2:
The patent optimizes parameters such as the focal length, curvature radius, and positioning of the concave reflecting mirror to control light concentration. By adjusting these parameters, the system maximizes power input while maintaining safe light intensity levels on the receiving element, preventing damage through careful parameter selection.
3Ease of manufacture
If the light receiving element size is kept small to reduce manufacturing cost, then the device complexity is reduced, but the number of optical fiber cables that can be connected is limited
Solution Approach 1:
The patent uses a three-dimensional concave reflecting mirror structure to accommodate multiple optical fiber cables from different spatial directions. This vertical and radial arrangement allows many cables to be connected to a small light receiving element, as the mirror collects light from the entire surrounding space and focuses it onto the compact receiver.
Solution Approach 2:
The concave reflecting mirror serves multiple functions simultaneously: it acts as a light collector, a light concentrator, and a spatial distributor. This multi-functional component enables a single small light receiving element to handle light from numerous optical fiber cables, eliminating the need for multiple separate receiving elements or a larger single element.
