Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If dedicated cables are installed from each remotely located computer and server to the system administrator's user console, then full access and operation of remote computer equipment is enabled, but substantial wiring and wire harnessing costs increase tremendously
Solution Approach 1:
The patent replaces the mechanical cable-based KVM extension system with a wireless communication system using 802.11b WLAN technology. The wireless adapter card enables communication between the remote computer and administrator's console without physical cable connections, thereby eliminating the need for substantial wiring and wire harnessing while maintaining full remote access capability.
2Adaptability or versatility
If the distance between the system administrator's user console and the remote computer equipment increases, then remote management flexibility improves, but the quality of the transmitted signal decreases
Solution Approach 1:
The patent utilizes 802.11b wireless communication technology which operates at 2.4 GHz with data rates up to 11 Mbps, providing reliable signal transmission over extended distances. The wireless adapter card implements robust error correction and signal processing algorithms to maintain signal quality and reliability as distance between the administrator's console and remote equipment increases, enabling flexible remote management without signal degradation.
3Ease of operation
If standard wireless systems are used for remote management, then wireless operation is enabled, but limited bandwidth results in keyboard, mouse, and video signal latency
Solution Approach 1:
The patent specifically implements 802.11b wireless technology with data rates up to 11 Mbps, which provides sufficient bandwidth to minimize latency in keyboard, mouse, and video signal transmission. The high data rate enables rapid transmission of control signals and video data, reducing the time delay experienced in wireless remote management operations compared to standard wireless systems.
4Length of stationary object
If UWB technology is used to extend transmission distance, then transmission range increases, but the technology currently has limited range of 10 to 20 feet
Solution Approach 1:
The patent employs 802.11b wireless access points as intermediary devices to extend the transmission range beyond the limited 10-20 foot range of UWB technology. The wireless adapter card communicates with remote computers through the WLAN infrastructure, using access points to relay signals over much longer distances, thereby overcoming the range limitation of direct UWB communication while maintaining reliable connection.
