Solution Overview

Problem

Optical power supply converters face limitations in increasing output power due to the small core diameter of single-mode optical fibers, which can lead to fiber fuse damage from high optical input, and increasing the number of fibers requires larger light receiving elements, increasing manufacturing costs.

Innovation Solution

An optical power supply converter design featuring a concave reflecting mirror with a partially concave surface of an ellipsoid of revolution, allowing multiple optical fibers to input light without increasing the size of the light receiving element, by reflecting light from the second focus to the first focus, thereby increasing optical input and output without damaging the light receiving element.

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

Engineering Contradiction:

Core Design Contradiction:
PowerVSEase of manufacture

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.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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.

Inventive Principle:
Principle #24Intermediary (Mediator)

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

Engineering Contradiction:

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.

Inventive Principle:
Principle #3Local quality

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.

Inventive Principle:
Principle #35Parameter changes

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

Engineering Contradiction:
Improvemanufacturing costVSAvoidnumber of optical fiber cables
Core Design Contradiction:
Ease of manufactureVSQuantity of substance

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.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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.

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