Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Infrared (IR) emitters and sensors are used for laser tag games, then the targeting and detection function is achieved, but the equipment cost becomes high
Solution Approach 1:
The patent replaces expensive specialized IR emitters and sensors with ordinary mobile phones that can perform the same targeting and detection functions. The mobile phone camera captures images of targets, and the phone's processor analyzes the images to determine hits or misses, effectively copying the functionality of dedicated laser tag equipment using widely available consumer devices.
Solution Approach 2:
The patent uses ordinary mobile phones, which are inexpensive compared to specialized IR emitters and sensors. Mobile phones are mass-produced consumer electronics with long lifecycles and low costs, making them ideal for replacing expensive specialized equipment while maintaining the required functionality for targeting and detection.
2Measurement precision
If specialized IR emitters and sensors are used, then accurate targeting is achieved, but accessibility and versatility are reduced
Solution Approach 1:
The patent makes the mobile phone serve multiple functions: it acts as the firearm, the target indicator, the detection device, and the communication device all in one. The same mobile phone can be used by different players for different roles in the game, and the system can accommodate various game modes and configurations, greatly enhancing accessibility and versatility.
Solution Approach 2:
The mobile phone uses its own built-in components (camera, processor, GPS, communication modules) to perform all targeting and detection functions without requiring external specialized equipment. The phone captures images, processes them to determine hits or misses, and communicates results, making the system self-sufficient and highly accessible to anyone with a mobile phone.

AI summary
A shooting simulation system. The system includes a plurality of communication devices with each communication device associated with a separate player. In addition, each mobile phone includes an A-GPS device for determining a location indicia of the communication device and a mechanism for communicating the location indicia to a network. A game server communicates with the network for relaying the location indicia of each communication device to all of the communication devices. Each communication device includes a mechanism for determining a directional orientation of the communication device when aimed and a processor for determining if a simulated targeting of another player is a hit or miss based on the location indicia of a shooting communication device, the location indicia of a communication device of a targeted player, and the directional orientation of the shooting communication device.
