Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired connections (DMX, Arcnet, ethernet) are used for lighting control, then reliable communication and control precision are achieved, but system flexibility and ease of installation are reduced
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless communication system. The lighting control console and lighting instruments communicate via wireless signals (such as radio frequency) instead of physical cables, eliminating the need for complex wiring while maintaining control functionality. This substitution resolves the contradiction by providing both wireless flexibility and reliable communication through protocol-level error correction and acknowledgment mechanisms.
Solution Approach 2:
The patent introduces a wireless communication protocol as an intermediary between the lighting control console and lighting instruments. This protocol layer handles data transmission, error detection, and correction without requiring physical connection, serving as a mediator that enables reliable communication while maintaining installation flexibility. The protocol includes features like packet acknowledgment and retransmission to ensure reliability.
2Stability of the object's composition
If wired connections are used for lighting control, then stable control is achieved, but potential for electromagnetic interference and system complexity increase
Solution Approach 1:
The patent replaces wired electrical connections with wireless electromagnetic communication, thereby eliminating the physical pathways through which electromagnetic interference could affect the control system. The wireless signals operate on frequencies that are less susceptible to industrial interference, and the protocol includes error detection and correction mechanisms to maintain control stability without vulnerable physical connections.
3Ease of operation
If wireless control is implemented, then system flexibility and ease of installation are improved, but communication security and reliability may be reduced
Solution Approach 1:
The patent implements a feedback mechanism in the wireless communication protocol where receiving devices send acknowledgment signals back to transmitting devices. If an acknowledgment is not received within a specified time window, the transmitting device retransmits the data. This feedback loop ensures reliable communication while maintaining wireless flexibility, resolving the contradiction between ease of installation and communication reliability.
Solution Approach 2:
The patent employs preliminary error detection and correction codes in the wireless data packets before transmission. By pre-processing the data with redundancy bits and checksums, the system prepares for potential transmission errors in advance, enabling reliable communication over the wireless medium without requiring complex post-transmission error handling, thus maintaining both flexibility and reliability.
