Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional items like glow sticks and wristbands are used to enhance entertainment effect, then the entertainment experience is improved, but the preparation complexity and human resource requirements increase significantly
Solution Approach 1:
The patent replaces traditional mechanical preparation methods (manual distribution of glow sticks and wristbands) with a wireless communication system using signal relay stations and frequency hopping technology. The main transmitting device sends control signals to multiple relay stations, which automatically distribute entertainment effects to audience devices, eliminating the need for manual preparation and distribution of physical items.
Solution Approach 2:
The system creates virtual copies of entertainment effects through wireless signal transmission. Instead of distributing physical glow sticks to each audience member, the system transmits control signals that enable audience devices to generate their own light effects, sounds, or vibrations, achieving the same entertainment purpose with minimal physical preparation.
2Area of stationary object
If multiple signal relay stations are deployed to cover large areas, then the coverage area is improved, but signal interference between stations increases
Solution Approach 1:
The patent implements frequency hopping where signal relay stations periodically switch between different frequency channels according to a predetermined sequence. When one station transmits on a particular frequency, other stations switch to different frequencies, creating periodic action patterns that avoid continuous interference. This allows multiple stations to operate simultaneously in the same area without significant signal conflict.
Solution Approach 2:
The system dynamically adjusts frequency allocation in real-time based on transmission needs. Signal relay stations do not operate on fixed frequencies but continuously hop between frequencies according to the frequency hopping sequence, making the frequency assignment dynamic rather than static. This dynamic approach allows the system to adapt to changing conditions and avoid interference automatically.
3Productivity
If synchronous broadcasting is implemented across multiple relay stations, then the coordination efficiency is improved, but the synchronization precision requirement increases
Solution Approach 1:
The patent incorporates a correcting time signal mechanism where the receiver at each signal relay station receives timing information and generates correction signals to adjust transmission timing. This feedback loop ensures that all relay stations synchronize their broadcasting activities by comparing their timing against a reference and making necessary adjustments, thereby maintaining synchronization precision while enabling coordinated operation across multiple stations.
4Reliability
If frequency hopping is used to avoid interference, then the signal reliability is improved, but the system complexity increases
Solution Approach 1:
The patent segments the frequency spectrum into multiple channels and assigns different frequency hopping sequences to different signal relay stations. Instead of using a single complex frequency management system, the overall system is divided into multiple independent frequency sequences that operate in parallel. Each relay station follows its own segmented frequency pattern, reducing the complexity of individual station design while maintaining overall system reliability through diversity.

AI summary
Embodiments of the present disclosure provide a signal relay station for large gatherings, capable of synchronously broadcasting with other signal relay stations. The signal relay station includes a receiver and a transmitter. The receiver is configured to receive to-be-broadcast data and output a correcting time signal. The transmitter is configured to receive the to-be-broadcast data and the correcting time signal from the receiver, and has packet broadcast events that occur respectively aligned with the other signal relay stations at a plurality of times according to the correcting time signal so as to broadcast the to-be-broadcast data. The transmitter broadcasts the to-be-broadcast data by using different frequency hopping between the signal relay station and the other signal relay stations.
