Short-Range Network Triggering for Mobile Receiver Light Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for generating light signals using mobile receiver units, such as in crowded events, face challenges with accurate location determination and high resolution, especially when individuals move, as they rely on fixed position assignment or GPS which is inaccurate and limited to open-air events.
Innovation Solution
A method where a trigger unit forms a short-range communication network with receiver units to determine their location through communication between units, using triangulation based on signal strength or transit time measurements, allowing for precise positioning and synchronized light signal generation.

Engineering Contradiction Analysis
1Adaptability or versatility
If GPS signals are used for location determination, then the method can be used for open-air events, but the positioning accuracy is only accurate to within a few meters
Solution Approach 1:
The system divides the area into multiple zones with defined boundaries and assigns receiver units to specific zones. Instead of relying on precise continuous positioning, the solution segments the space into discrete regions where receivers are allocated, thereby achieving sufficient positioning accuracy for the application without requiring high-precision GPS.
Solution Approach 2:
The patent implements zone-specific receiver assignment where different areas have different receiver allocations based on local requirements. Each zone has tailored receiver units assigned to it, optimizing the system for local conditions rather than using a uniform approach across the entire event area.
2Device complexity
If fixed position assignment is used, then position determination is simple, but the system cannot handle moving crowds of people
Solution Approach 1:
The system dynamically reassigns receiver units to different zones based on real-time crowd movement and zone occupancy. When people move between zones, the system automatically updates receiver assignments to match the new spatial distribution, maintaining system effectiveness for mobile crowds while keeping the underlying position determination mechanism relatively simple.
Solution Approach 2:
The system continuously monitors zone occupancy and receiver unit positions, using this feedback information to dynamically adjust receiver assignments. This feedback loop enables the system to adapt to moving crowds by reallocated receivers based on current spatial distribution without requiring complex predetermined positioning.
3Manufacturing precision
If a large number of receiver units are used for high-resolution visual representation, then the quality of light phenomena improves, but the communication overhead increases
Solution Approach 1:
The system combines multiple receiver units into zone groups that can be controlled collectively. Instead of managing each receiver unit individually, the patent merges receivers within zones into coordinated groups, reducing communication overhead by sending control signals to zones rather than to each individual receiver, while still achieving high-resolution visual representations through the coordinated action of multiple receivers.
