Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired connections are used to transmit sensor outputs to multiple users, then reliable data transmission is achieved, but safety hazards increase and training efficiency decreases
Solution Approach 1:
The patent replaces mechanical wired connections with wireless electromagnetic field-based transmission. The sensor unit transmits audio outputs wirelessly to receiving units, eliminating physical cables and connectors that pose safety hazards while maintaining reliable data transmission through radio frequency communication.
2Stability of the object's composition
If wired connections are used for sensor output transmission, then stable connection is maintained, but device complexity and ease of operation are reduced
Solution Approach 1:
The patent substitutes mechanical connection systems with wireless electromagnetic transmission. The sensor unit and receiving units communicate through wireless signals, eliminating the need for physical plugging and unplugging of cables, thereby reducing device complexity while maintaining connection stability through continuous wireless communication.
3Adaptability or versatility
If wired connections are used to connect multiple users to sensor outputs, then all users can access data, but training efficiency and operational flexibility are reduced
Solution Approach 1:
The patent replaces wired multi-user access systems with wireless transmission. Multiple receiving units can simultaneously and independently connect to the sensor unit wirelessly, allowing flexible movement and positioning of users without being constrained by physical cable routing, thereby improving training efficiency while maintaining multi-user access capability.
4Loss of information
If physical connections are used for sensor output transmission, then direct communication is established, but safety hazards and operational risks increase
Solution Approach 1:
The patent substitutes direct physical connections with wireless electromagnetic communication. The sensor unit transmits information directly to receiving units through wireless signals, maintaining communication directness and information integrity while eliminating the safety hazards associated with physical cable connections in hazardous environments.
Data Source
AI summary
A system for wireless multiple user access to a sensor comprises a sensor unit having a sensor element (e.g. a leak detector), a sensor user interface, and a sensor wireless transceiver that transmits information corresponding to the sensor output. One or more receiving units each receive the sensor information corresponding to the output of the sensor user interface, and provide that output to a receiver user interface. Multiple receiving units may be used, for example, by students receiving training on the use of a sensor unit. An instructor unit can provided to allow an instructor to review the sensor information and create instructional commentary that is transmitted to each of the student receiver units along with the sensor information.
