Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple physical links and channels are employed for data communications, then communication versatility and redundancy are improved, but timing coordination, security, data packet sequencing, and system complexity are worsened
Solution Approach 1:
The patent implements a hierarchical protocol structure where multiple specialized protocols are nested within the transport packet layer. Each protocol handles specific link characteristics, while the underlying transport layer provides unified security and coordination, effectively nesting specialized protocols within a general framework to manage complexity.
Solution Approach 2:
The transport packet layer acts as an intermediary between multiple specialized protocols and the network layer. It receives data from various protocols, applies unified security measures, manages packet sequencing, and coordinates timing across different links, thereby mediating the complexity of multi-link communication.
2Adaptability or versatility
If device mobility and channel switching are implemented in wireless communications, then communication adaptability is improved, but security constraints and data loss are worsened
Solution Approach 1:
The system performs preliminary actions by establishing security contexts and encryption keys before actual data transmission begins. The transport packet layer pre-configures security parameters and packet sequencing mechanisms in advance, so that when channel switching occurs during mobility, security and connectivity are maintained without interruption or data loss.
3Productivity
If specialized protocols are used for wireless communications, then communication efficiency is improved, but security implementation complexity is worsened
Solution Approach 1:
The patent segments the communication system into distinct layers: specialized protocols handle efficient data transmission specific to each wireless technology, while the transport packet layer separately handles security and coordination. This segmentation allows each layer to focus on its specific function, improving efficiency while simplifying security implementation.

AI summary
A communications system provides for secure communications of information over multiple communications links. The system includes a client device, a server device, and at least one, and typically multiple, available and usable communications channels, elements, modes and links for connecting the devices for communications of information therebetween. The system includes a link detector for determining existence and usability of the communications links for communications of the information, a pathfinder for selecting one or more of the communications links for communications of at least some of the information, a link handover for switching to the selected one or more communications links for communications of the information or portion thereof, and an auto reconnector for re-connecting to detected and selected one or more communications links for communications of the information or portions of it in the event that any communication is hindered, terminated or upset.
