Flying Body Reflective Surface Control for Position Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for precisely measuring a flying body's position in the sky or space using a reflector allow others to determine its location, raising concerns about privacy and unauthorized tracking.
Innovation Solution
A flying body equipped with a reflector, controller, and anti-reflection section that controls the reflection of laser beams based on its position and observation permissions, preventing reflection in unauthorized areas while allowing reflection in permitted areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a reflector is provided on the flying body to enable precise position measurement, then measurement precision is improved, but the flying body's position becomes accessible to unauthorized observers
Solution Approach 1:
The reflector's reflective surface is made dynamically controllable through a rotation section that changes its orientation based on the flying body's position and observation permissions. This dynamic adjustment allows the system to enable or disable reflection functionality in real-time, resolving the contradiction between maintaining measurement precision and preventing unauthorized tracking.
Solution Approach 2:
The anti-reflection section selectively controls reflection properties in different spatial directions and conditions. By using a shutter mechanism that can be opened or closed based on location, the system creates local variations in reflectivity - allowing reflection when authorized and blocking it when unauthorized - thus resolving the contradiction between measurement precision and security.
2Object-affected harmful factors
If a shutter is added to control laser reflection intensity, then position measurement security is improved, but device complexity increases
Solution Approach 1:
The shutter function is merged with the existing reflector structure, creating an integrated anti-reflection section that combines both components into a unified system. This reduces overall device complexity by eliminating separate control mechanisms while maintaining the security function of preventing unauthorized measurement.
Solution Approach 2:
The controller automatically manages the shutter and rotation section based on pre-stored position information and observation permissions, enabling the system to self-regulate reflection control without external intervention. This self-service capability reduces operational complexity while maintaining security functions.
3Adaptability or versatility
If the reflective surface direction is dynamically controlled, then selective position measurement control is improved, but device complexity and energy consumption increase
Solution Approach 1:
The rotation section serves multiple functions: it controls reflective surface orientation for selective measurement control, works in conjunction with the shutter for enhanced security, and adapts to different flying body positions. This multi-functionality justifies the added complexity by providing versatile control capabilities from a single mechanism.
Solution Approach 2:
The controller receives feedback about the flying body's position and observation permissions, then automatically adjusts the rotation section and shutter accordingly. This feedback mechanism enables adaptive control that responds to changing conditions, improving versatility while managing complexity through automated decision-making based on pre-stored authorization data.

AI summary
A flying body, which prevents others from measuring precise position of the flying body and allows friends to measure precise position of the flying body, is provided. The flying body (10) is provided with a reflector (100), a controller (300) and an anti-reflection section (200). The reflector (100) is provided with a reflective surface, arranged in an aperture, which reflects a radiated laser. The controller (300) generates a control signal on a basis of a state of the flying body. The anti-reflection section (200) prevents a reflection of the laser by the reflective surface on a basis of the control signal.
