Fluid Stream Signal Detection via Internal Reflection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional target-based attractions using fluid sources, such as water cannons, face challenges in determining which fluid stream successfully hits a target, leading to inaccurate awarding of points or actions, especially when multiple streams are directed at the same target.
Innovation Solution
The system incorporates a fluid source that emits a stream with a unique signal encoded via internal reflection, allowing sensors to distinguish between fluid streams and identify the source, enabling accurate determination of which stream hits the target and facilitating appropriate actions based on this information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple fluid streams are directed at the same target, then the entertainment value and interaction of the attraction is improved, but the ability to accurately determine which stream hits the target deteriorates
Solution Approach 1:
The patent divides the identification problem into segments by assigning unique identifiers to each fluid stream source. Each transmitter is associated with a specific fluid source and emits a signal with a unique parameter combination, allowing the sensor to identify which specific stream hit the target even when multiple streams are present simultaneously.
Solution Approach 2:
The patent uses signal parameter variations (analogous to color changes) to distinguish between different fluid streams. Each transmitter emits signals with unique parameter combinations that can be detected and differentiated by the sensor, enabling accurate identification of the hitting stream among multiple concurrent streams.
2Measurement precision
If a signal is transmitted through the fluid stream via internal reflection, then the identification accuracy of the fluid stream source is improved, but the device complexity increases
Solution Approach 1:
The patent introduces signals as intermediaries that carry identification information through the fluid stream. These signals act as mediators between the fluid source and the sensor, enabling identification without requiring direct contact or complex physical modifications to the fluid stream itself.
Solution Approach 2:
The patent replaces complex mechanical tracking systems with an optical/electromagnetic signal-based identification system. Instead of mechanically tracking which physical stream hits the target, the system uses transmitted signals with unique parameters to identify the source, simplifying the overall system architecture.
3Use of energy by moving object
If the fluid stream geometry is optimized for internal reflection, then the signal transmission through the fluid stream is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent optimizes the geometry parameters of the fluid stream to facilitate internal reflection of signals. By carefully controlling parameters such as stream diameter, flow velocity, and coherence, the system achieves sufficient signal transmission without requiring extreme manufacturing precision, balancing performance with practical manufacturability.
