Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If terrestrial base stations are deployed to provide two-way data communication, then data transmission capability is improved, but infrastructure cost and device complexity increase significantly
Solution Approach 1:
The patent extracts the communication function from traditional terrestrial base stations and implements it through satellite-based transponders. This removes the need for expensive ground-based infrastructure while maintaining two-way data communication capability, directly resolving the contradiction between reliability and infrastructure cost
Solution Approach 2:
The patent introduces satellite transponders as intermediary devices that relay data between remote terminals and central systems. This intermediary approach enables two-way communication without requiring expensive terrestrial base station infrastructure, resolving the contradiction by providing an alternative communication path
2Area of stationary object
If satellite-based systems are used to expand geographic coverage, then coverage area is improved, but infrastructure cost and maintenance complexity increase
Solution Approach 1:
The patent designs satellite transponders to serve multiple functions: providing geographic coverage expansion, enabling two-way data communication, and reducing infrastructure costs. This multi-functionality allows a single satellite-based system to address multiple problems simultaneously, resolving the contradiction between coverage area and infrastructure cost
Solution Approach 2:
The patent changes the operational parameters from terrestrial frequency bands to satellite-appropriate frequency bands, and from ground-based transmission to space-based transmission. These parameter changes enable wide geographic coverage while utilizing existing satellite infrastructure, reducing the need for additional infrastructure investment
3Productivity
If high carrier frequencies are used for data transmission, then data rate is improved, but penetration capability through building structures deteriorates
Solution Approach 1:
The patent changes the frequency parameter from high carrier frequencies to lower frequency bands that are more suitable for satellite transmission. This parameter change maintains data transmission capability while improving penetration through building structures, as lower frequencies experience less attenuation when passing through obstacles
4Productivity
If cellular networks are deployed to provide wide area coverage, then data rate is improved, but infrastructure cost and geographic coverage deteriorate in remote areas
Solution Approach 1:
The patent extracts the communication service from terrestrial cellular networks and delivers it through satellite transponders. This extraction enables data transmission in remote areas where cellular infrastructure is unavailable, resolving the contradiction between data rate and geographic coverage by providing an alternative delivery mechanism
Solution Approach 2:
The patent transitions from two-dimensional ground-based cellular coverage to three-dimensional satellite-based coverage. This dimensional change allows the system to provide wide area geographic coverage including remote areas, while maintaining data transmission capabilities through the satellite dimension
