Wireless Communication System with Segmented Relay for Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems for teams, such as sports teams, pose safety risks due to high power devices and have limited range, and lack selective communication capabilities, making it difficult for players to communicate effectively over long distances.
Innovation Solution
A wireless communication system using a first wireless communication protocol for long-range transmission and a second, lower power protocol for short-range communication, with wearable audio devices allowing team members to hear ambient sounds and enabling selective message transmission through a group routing controller and stick trigger or epaulet speakers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If high power wireless communication devices are used for long-range transmission, then communication range is improved, but safety risks increase
Solution Approach 1:
The communication system is divided into two segments: a long-range high-power transmission segment (first wireless protocol) and a short-range low-power reception segment (second wireless protocol). This segmentation allows the system to achieve long-range communication capability while keeping the power level near the user's head low, thus resolving the contradiction between communication range and safety risks.
Solution Approach 2:
A relay device acts as an intermediary between the transmitter and the wearable audio device. The relay receives the oral message via the first wireless protocol over long range, then retransmits it via the second wireless protocol to the wearable audio device at low power. This intermediary approach enables long-range communication while maintaining safety by preventing high-power devices from being mounted close to the user's head.
2Object-affected harmful factors
If low power wireless devices are used for safety, then safety risks are reduced, but communication range is limited
Solution Approach 1:
The communication path is segmented into two stages: first, long-range transmission using a high-power protocol from the base transmitter; second, short-range transmission using a low-power protocol from the relay to the wearable audio device. This allows the system to utilize high-power capability for long-range communication while keeping low-power devices close to the user's head, thus reducing safety risks without sacrificing communication range.
3Ease of operation
If players can communicate freely at all times, then communication ease is improved, but selective communication capability deteriorates
Solution Approach 1:
The communication system provides dynamic control over message transmission through the relay device, which can selectively forward oral messages to specific wearable audio devices based on real-time conditions. This dynamic selectivity allows players to communicate easily when needed while maintaining the ability to restrict communication to specific teammates, thus resolving the contradiction between communication ease and selective capability.

AI summary
A wireless communication system comprises a first wireless communication device for a first team member, and a second wireless communication device for a second team member. The first wireless communication device comprises a microphone and a transmitter for transmitting an oral message via a first wireless communication protocol. The second wireless communication device comprises a main transceiver, a headset, and a support for mounting the main transceiver to the second team member remotely from the headset. The main transceiver receives the oral message from the first wireless communication device via the first communication protocol and retransmits the oral message via a second wireless communication protocol to the headset for generating audio corresponding to the oral message. The second wireless communication protocol operates at a lower power than the first wireless communication protocol, and the first communication protocol operates over a longer range than second wireless communication protocol.
