Smart Dart UWB Hit Detection for Toy Battle Games
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interactive game systems fail to accurately detect and track hits from toy projectiles, such as darts, fired from blasters, especially from multiple angles, and do not effectively accumulate hit points for gameplay purposes in a reliable and efficient manner.
Innovation Solution
The system employs conductive suits and smart darts with embedded Ultra-Wide Band (UWB) technology and capacitive charging, allowing for precise hit detection and tracking through communication between smart blasters and darts, using conductive tips and printed circuit boards to facilitate accurate player identification and hit resolution without the need for a server, enabling peer-to-peer communication and cloud-based data management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional toy projectile systems are used, then the system is simple and easy to manufacture, but hit detection accuracy and reliability are insufficient
Solution Approach 1:
The patent merges multiple functions into the smart dart: capacitive sensing for hit detection, UWB transceiver for communication and positioning, and onboard memory for data storage. This integration allows accurate hit detection and tracking without requiring separate complex systems for each function, resolving the contradiction between measurement precision and device complexity.
Solution Approach 2:
The patent replaces mechanical hit detection methods (such as physical sensors or visual observation) with electronic and electromagnetic systems. The capacitive tip detects hits through electrical contact, while UWB technology provides wireless communication and positioning, eliminating the need for complex mechanical sensor arrays or server-based tracking systems.
2Reliability
If server-based hit resolution systems are used, then centralized data management is achieved, but system complexity and cost increase
Solution Approach 1:
The smart blaster performs hit resolution autonomously by receiving UWB signals from smart darts, determining hit coordinates through signal triangulation, and updating player hit points without server intervention. This self-service capability maintains reliable hit tracking while eliminating the need for complex server-based arbitration and centralized data management.
Solution Approach 2:
The UWB signal acts as an intermediary carrier that transports hit detection data from the smart dart to the smart blaster. This wireless intermediary enables reliable data transmission without requiring physical connections or complex wired infrastructure, reducing system architecture complexity while maintaining tracking reliability.
3Adaptability or versatility
If multiple angle hit detection is implemented, then comprehensive player hit tracking is achieved, but detection reliability from various angles becomes challenging
Solution Approach 1:
The patent uses UWB signal phase information to determine the angle of incoming darts. By analyzing phase differences in signals received from multiple antennas, the system accurately identifies hit locations on players regardless of dart trajectory angle, maintaining reliable detection across all directions without requiring physical adjustment of sensor orientations.
