Engineering Contradiction Analysis
1Reliability
If physical connections are used to transmit audio outputs, then reliability of connection is improved, but safety hazards increase and ease of operation deteriorates
Solution Approach 1:
The patent replaces the mechanical connection system (physical cables and connectors) with an electromagnetic field-based wireless transmission system. The sensor unit's audio output is transmitted via radio frequency signals to receiver units, eliminating the need for physical tethers while maintaining connection reliability through error correction protocols and signal redundancy.
2Stability of the object's composition
If physical connections are used to transmit audio outputs, then connection stability is improved, but ease of operation deteriorates due to physical tethers
Solution Approach 1:
The patent substitutes mechanical cable connections with wireless electromagnetic transmission, allowing operators to move freely without physical constraints. The system maintains connection stability through automatic signal tracking and handoff protocols when multiple receivers are involved.
Solution Approach 2:
The wireless transmission system provides multi-functionality by supporting both single-user and multi-user scenarios. The sensor unit can simultaneously transmit to multiple receiver units, enabling collaboration and training functions while maintaining operational simplicity for all users.
3Ease of operation
If wireless transmission is implemented, then safety is improved and ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent introduces a wireless transceiver subsystem as an intermediary between the sensor unit and receiver units. This dedicated wireless communication module handles the complexity of signal modulation, transmission, and reception, keeping the main sensor functionality simple while enabling safe and easy wireless operation.

AI summary
A system for wireless multiple user access to a sensor comprises a sensor unit having a sensor element, a sensor user interface, and a sensor wireless transceiver that transmits information corresponding to the output of the sensor user interface. One or more receiving units each receive the information corresponding to the output of the sensor user interface, and provide that output to a receiver user interface. The receiver may be located near the sensor unit, or may be located remotely from the sensor unit. Multiple receiving units may be used, for example, by students receiving training on the use of a sensor unit.
