Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If machines are spaced closer together to reduce occupied floor space, then area utilization is improved, but wireless signal interference increases
Solution Approach 1:
The patent divides the wireless communication environment into separate segments by enclosing individual machines in Faraday cages. Each cage creates an isolated electromagnetic environment, allowing machines to be spaced closely together while preventing wireless signal interference between them. This segmentation enables dense machine placement without compromising communication reliability.
2Productivity
If the same wireless frequency is reused for multiple machines to optimize bandwidth usage, then bandwidth efficiency is improved, but signal interference between machines increases
Solution Approach 1:
The Faraday cage acts as an intermediary barrier between machines using the same wireless frequency. The conductive enclosure blocks electromagnetic fields, allowing frequency reuse across multiple machines while preventing harmful interference. This intermediary structure enables efficient bandwidth utilization without sacrificing signal integrity.
3Reliability
If Faraday cages are implemented to block electromagnetic fields and prevent interference, then wireless signal reliability is improved, but device complexity increases
Solution Approach 1:
The patent employs Faraday cages constructed from conductive materials that form enclosing shells around machines. These cages, while adding structural elements, provide effective electromagnetic shielding with relatively simple implementations. The cages can be integrated into existing machine structures, balancing the improvement in wireless reliability against the added structural complexity.
