Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the bandwidth of one radio channel is used to cover both uplink and downlink transmissions, then the system complexity is reduced, but the channel bandwidth is not broad enough to encompass both transmissions simultaneously
Solution Approach 1:
The patent introduces a frequency transformation dimension by mapping signals from a wide bandwidth known band to a narrower predetermined band through mathematical transformation. This allows the channel device to process signals in a transformed frequency domain where the effective bandwidth requirements are reduced, while still supporting both uplink and downlink transmissions.
Solution Approach 2:
The patent changes the frequency domain parameters by transforming signals from one frequency band to another. The frequency transformer converts signals from the known band with wider bandwidth to the predetermined band with narrower bandwidth, enabling the channel device to handle both uplink and downlink within its limited bandwidth capability.
2Area of stationary object
If multiple radio channels are used to accommodate different bandwidth requirements, then the bandwidth requirement is satisfied, but the number of required radio channels exceeds the number of available radio channels
Solution Approach 1:
The patent makes a single radio channel capable of handling multiple functions by transforming different bandwidth requirements into a common predetermined band. The frequency transformer enables one radio channel to serve multiple purposes by mathematically mapping different input bandwidths to a standardized output band that fits within the channel device's capabilities.
Solution Approach 2:
The patent resolves the channel quantity shortage by introducing a frequency transformation dimension. Instead of requiring multiple physical channels, the system transforms signals from multiple bandwidth requirements into a unified transformed domain, allowing a single channel to handle what would otherwise require multiple channels.
3Area of stationary object
If multiple radio channels are used to handle different transmission requirements, then the bandwidth requirement is met, but resource wastage occurs due to excessive use of radio channels
Solution Approach 1:
The patent eliminates resource wastage by making the radio channel universal. Instead of allocating multiple dedicated channels for different bandwidth requirements, the frequency transformer enables a single channel to handle diverse transmission requirements efficiently, reducing the total resource consumption while meeting all bandwidth needs.

AI summary
A frequency manipulator comprises a frequency transformer and a frequency retransformer. The frequency transformer receives each of at least one signal in a known band from at least one transmitter, transforms the known band of each signal into a predetermined band and forwards each signal in the predetermined band to a channel device. The frequency retransformer receives each signal from the channel device, retransforms the predetermined band of each signal to the known band and forwards each signal in the known band to at least one receiver.
