Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple antennas are installed by different business operators, then each operator can provide wireless services independently, but installation costs increase and space constraints are exacerbated
Solution Approach 1:
The patent combines multiple antennas from different business operators into a shared antenna system. The antenna sharing device allows operators A and B to共用 the same physical antenna infrastructure, reducing the total number of antennas installed while maintaining independent service capabilities through signal separation mechanisms
Solution Approach 2:
The shared antenna system serves multiple functions: it provides wireless services for multiple business operators simultaneously, supports MIMO technology for improved data transmission, and enables frequency band differentiation. The single antenna infrastructure performs what previously required multiple separate antenna systems
2Adaptability or versatility
If separate antenna systems are used by each business operator, then service independence is maintained, but installation space requirements increase
Solution Approach 1:
The patent merges separate antenna systems into a shared configuration where multiple operators' signals are combined and transmitted through common antenna elements, dramatically reducing the physical space required for antenna installation while preserving operator independence through signal processing separation
3Productivity
If multiple antennas are installed for MIMO technology across different frequency bands, then data transmission speed is improved, but mutual interference between operators increases
Solution Approach 1:
The patent introduces filter couplers as intermediary devices between the transceiving units and shared antennas. These filter couplers act as mediators that separate signals from different frequency bands and operators, allowing MIMO technology to operate across multiple frequency bands without causing mutual interference between operators
4Reliability
If independent antenna systems are deployed by each operator, then service reliability is maintained, but management efficiency decreases
Solution Approach 1:
The shared antenna system provides universal service to multiple operators through a single infrastructure. The filter coupler configuration enables each operator to access their designated frequency bands independently while sharing the common antenna resources, improving management efficiency without compromising service reliability
