Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a wired Ethernet connection is used for gigabit internet access, then high-speed internet connectivity is achieved, but wireless access to notebook computers and portable devices is not possible
Solution Approach 1:
The patent introduces a wireless network interface device as an intermediary component that converts wired Ethernet signals to wireless signals. This mediator enables notebook computers and portable devices to access gigabit internet wirelessly without modifying the existing wired Ethernet infrastructure, thus resolving the contradiction between maintaining high-speed wired connectivity and enabling wireless access.
Solution Approach 2:
The patent replaces the mechanical/wired connection system with a wireless electromagnetic signal transmission system. By substituting the physical Ethernet cable connection with wireless RF signals in the 60 GHz band, the system enables portable devices without physical ports to access gigabit internet while maintaining the same high-speed performance.
2Ease of manufacture
If a network interface apparatus is designed for desktop computers, then gigabit wired Ethernet conversion is achieved, but compatibility with notebook computers and portable devices is limited
Solution Approach 1:
The patent designs the network interface apparatus with universal functionality to work with multiple device types including desktop computers, notebook computers, and portable devices. The wireless network interface device incorporates both a wired Ethernet interface for desktops and a wireless RF transmission capability that serves notebooks and portable devices, making the system adaptable to various form factors and connection requirements.
Solution Approach 2:
The patent implements dynamic signal conversion capabilities that adapt to different device requirements. The wireless network interface device can dynamically adjust between converting wired Ethernet signals for desktop PCs and transmitting wireless signals for portable devices, providing flexible compatibility across different device types without requiring separate specialized hardware for each device category.
3Adaptability or versatility
If wireless transmission is implemented using conventional frequency bands, then basic wireless connectivity is achieved, but gigabit-speed wireless Ethernet transmission is not possible
Solution Approach 1:
The patent changes the frequency parameter of wireless transmission to the 60 GHz band, which provides sufficient bandwidth to support gigabit-speed wireless Ethernet transmission. By selecting this specific frequency band with higher available spectrum, the system achieves both wireless connectivity and high-speed data transmission capability that conventional lower frequency bands cannot provide.
