Screen Device Photoelectric Power for Flying Object Flight Time
Solution Overview
Problem
Conventional screen devices and image projection systems using flying objects are limited by the capacity of flight powering batteries, resulting in short flight times.
Innovation Solution
A screen device with photoelectric conversion elements that generates electric power from received image light, which is then used to supply power to a flying object, along with a flight controller to manage the flight and positioning of the object.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a flight powering battery is carried on the flying object, then the flying object can fly, but the flight time is limited to only ten and several minutes due to battery capacity constraints
Solution Approach 1:
The patent applies preliminary action by having the photoelectric conversion elements generate and store electrical energy in advance during daylight hours when sunlight is available. The power storage unit accumulates energy before it is needed, allowing the flying object to operate during nighttime or periods when direct sunlight is unavailable, thereby extending flight time beyond what a conventional battery alone could provide.
Solution Approach 2:
The system implements self-service by using the flying object's own screen as a photoelectric conversion element that generates electrical energy from sunlight. This eliminates or reduces the need for external power sources or frequent battery replacements, as the system sustains itself by converting ambient light into usable electrical power for its operation.
2Weight of moving object
If the battery is made light in weight to be carried on the flying object, then the flying object can fly, but the battery capacity is limited
Solution Approach 1:
The patent merges the screen function with photoelectric conversion functionality. The screen serves dual purposes: displaying images and generating electrical energy through photoelectric conversion elements. This integration eliminates the need for a separate, heavy battery system, as the combined screen-power generation unit provides both visual output and sustained power supply with minimal additional weight.
Solution Approach 2:
The screen is designed with multi-functionality, serving both as a display device and as a power generation system through integrated photoelectric conversion elements. This universal design allows the same component to fulfill multiple roles, reducing the overall system weight while maintaining adequate power capacity for extended flight operations.

AI summary
A screen device includes a screen, a plurality of first photoelectric conversion elements, a plurality of second photoelectric conversion elements, a flying object, a support member, and a controller. The plurality of first photoelectric conversion elements are on the screen and are arranged at an outermost periphery, in a frame shape, of an area in which photoelectric conversion elements are arranged. The plurality of second photoelectric conversion elements are on the screen and are arranged inside the area at the outermost periphery covered by the plurality of first photoelectric conversion elements. The flying object is configured to be powered by electric power generated by the plurality of second photoelectric conversion elements. The support member connects the screen with the flying object. The controller is configured to control the flying object based on an evaluation of the electric power generated by the plurality of first photoelectric conversion elements.
