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 signal quality deteriorate due to structural barriers and noise interference
Solution Approach 1:
The patent divides the wireless communication channel into multiple frequency channels. The system can switch between different channels (e.g., channels 1, 2, 3) to avoid interference from structural barriers and noise sources. This segmentation of the communication spectrum allows the system to maintain reliable connectivity while preserving wireless flexibility.
Solution Approach 2:
The patent implements dynamic channel adjustment where the system can change communication channels in real-time based on detected interference conditions. The mesh network dynamically routes signals through alternative paths and adjusts frequency usage to overcome structural barriers and noise, maintaining reliability while preserving wireless adaptability.
2Reliability
If wired networks are used for building automation, then reliability is improved, but cost and installation complexity increase
Solution Approach 1:
The patent replaces the mechanical wired communication system with a wireless mesh network that uses radio frequency communication. By substituting physical cable infrastructure with wireless signals, the system achieves comparable reliability through protocol-level error correction and redundant routing, while eliminating the high installation complexity and cost associated with wiring.
Solution Approach 2:
The patent introduces mesh network nodes as intermediary devices that relay communications between end devices. These nodes provide signal regeneration, error correction, and alternative routing capabilities that compensate for the lack of direct wired connections, maintaining reliability without requiring intrusive wiring installation.
3Ease of manufacture
If wireless networks are used, then ease of installation is improved, but signal transmission quality worsens due to noise and structural barriers
Solution Approach 1:
The patent segments the communication spectrum into multiple frequency channels to distribute and mitigate the impact of noise interference. By dividing the communication load across multiple channels, the system maintains ease of wireless installation while reducing susceptibility to any single noise source or structural barrier.
Solution Approach 2:
The patent implements feedback mechanisms where the mesh network monitors signal quality and automatically adjusts channel selection and transmission parameters. This feedback loop allows the system to maintain ease of installation while dynamically compensating for noise and interference conditions detected in the environment.
