Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If receiver units are placed remotely from the mixer-recorder to reduce transmission distance and improve signal reliability, then audio transmission reliability is improved, but cabling complexity increases
Solution Approach 1:
The system is divided into separate functional modules: a receiver unit that can be remotely positioned near the transmitter, and a mixer-recorder that remains stationary. These modules are connected through a simplified interface that separates audio data transmission from power transmission, allowing the receiver to be placed remotely without increasing overall system complexity.
Solution Approach 2:
An intermediary connection system is introduced between the remotely positioned receiver unit and the mixer-recorder. This intermediary interface handles both audio data and power transmission through a unified connection mechanism, simplifying the overall cabling architecture while enabling remote placement of the receiver unit.
2Device complexity
If receiver units are integrated into the mixer-recorder to eliminate cabling, then cabling complexity is reduced, but adaptability to remote positioning is lost
Solution Approach 1:
The integrated receiver-mixer unit is segmented into separate functional components that can be physically separated. The receiver unit maintains the ability to connect to the mixer-recorder through a standardized interface, providing both the simplicity of integration and the flexibility of separation when needed.
Solution Approach 2:
The connection between the receiver unit and mixer-recorder is made dynamic rather than fixed. The receiver unit can be easily connected to or disconnected from the mixer-recorder through a quick-release mechanism, allowing the system to adapt between integrated and separated configurations based on operational requirements.
3Reliability
If a secure fixed connection is used to ensure reliable audio data transmission, then transmission reliability is improved, but ease of repositioning the receiver module is reduced
Solution Approach 1:
The connection mechanism transitions from a fixed permanent connection to a dynamic quick-release connection. The interface provides secure electrical contacts for reliable audio and power transmission when connected, while allowing rapid disconnection and repositioning when needed through a simple actuation mechanism.
Solution Approach 2:
The connection interface is designed to extract the receiver unit from the mixer-recorder body as a separate, removable module. This extraction capability allows the receiver to be securely connected during operation for reliable transmission, while enabling easy removal and repositioning when required.

AI summary
Methods and devices are provided for the modular construction of a mixer-recorder and wireless receiving modules, where the receiving modules may be optionally attached directly to the mixer-recorder without the need for cabling between them and/or in combination with corded units placed in the vicinity of the mixer-recorder.
