Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If configuration information is written to each projector individually using NFC, then configuration accuracy is ensured, but productivity decreases due to repeated manual operations
Solution Approach 1:
The patent applies the copying principle by enabling a configured projector to transmit its configuration information to other projectors through NFC communication. The configuration data is copied from the source projector to target projectors, eliminating the need for repeated manual configuration operations while maintaining configuration accuracy. This allows bulk configuration of multiple projectors through a single source configuration.
2Reliability
If multiple projectors are configured sequentially one by one, then configuration reliability is maintained, but loss of time increases due to repetitive setup processes
Solution Approach 1:
The patent implements preliminary action by performing the configuration operation on a single source projector first, then using this pre-configured projector to automatically transmit its configuration to multiple other projectors. This preliminary configuration step eliminates the need to repeat the entire configuration process for each projector, significantly reducing setup time while maintaining reliability through the automated transmission process.
3Ease of operation
If NFC communication is used for data transfer between terminal device and projector, then ease of operation is improved, but device complexity increases due to additional wireless communication components
Solution Approach 1:
The patent applies universality by making the projector serve multiple functions: it acts as both an NFC tag (first wireless communicator) for receiving configuration data and as an NFC reader/writer (second wireless communicator) for transmitting configuration data to other projectors. This multi-functionality eliminates the need for separate dedicated devices for configuration and data transmission, reducing overall system complexity while maintaining ease of operation.
