Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless communication networks are used for building automation, then flexibility and expandability are improved, but reliability and quality are worsened due to structural barriers and noise interference
Solution Approach 1:
The patent implements an acknowledgment mechanism where receiving nodes send feedback signals back to transmitting nodes to confirm successful frame reception. This feedback loop ensures reliable communication by allowing retransmission of frames that were not successfully received, thereby resolving the reliability issue while maintaining wireless flexibility.
Solution Approach 2:
The patent introduces intermediate nodes in the mesh network that relay communications between transmitting and receiving nodes. These intermediary nodes help overcome structural barriers by routing signals through multiple paths, ensuring reliable delivery even when direct communication is blocked by physical obstacles.
2Reliability
If wired networks are used for building automation, then reliability is improved, but cost and ease of installation are worsened
Solution Approach 1:
The patent replaces the mechanical wired communication system with a wireless mesh network that uses radio frequency communication. This substitution eliminates the need for physical wiring infrastructure while implementing reliability mechanisms through software-based acknowledgments and retransmission protocols, thereby achieving wired-level reliability without the associated costs and installation complexity.
3Ease of operation
If wireless communication is used in building automation, then ease of installation is improved, but quality and reliability are worsened due to noise sources and structural barriers
Solution Approach 1:
The patent segments the communication process into distinct phases: frame transmission, acknowledgment reception, and retransmission if needed. This segmentation allows the system to maintain simple wireless installation while ensuring quality through systematic error handling and verification at each communication stage.
Solution Approach 2:
The acknowledgment mechanism provides continuous feedback to ensure successful communication. Receiving nodes send confirmation signals back to transmitting nodes, and if acknowledgments are not received, retransmission occurs. This feedback loop maintains high communication quality without complicating the wireless installation process.

AI summary
In embodiments of the present invention improved capabilities are described for sending a single cast frame from a first node to a second node in a mesh network; sending the single cast frame from the second node to a third node in a mesh network; using the first node to detect the single cast frame sent from the second node to the third node; and interpreting this detection within the first node as an acknowledgement of success in sending the single cast frame from the first node to the second node. An additional method described herein may send a second single cast from the second node to a third node in a mesh network, interpret detection of the second single class frame within the first node as an acknowledgement of success in sending the first single cast frame from the first node to the second node.
