Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication apparatuses operating in both child and parent station modes face challenges in efficiently managing frequency bands, leading to interference and reduced convenience as the number of devices increases, particularly in concurrent infrastructure and direct connection modes.
Innovation Solution
A communication apparatus that simultaneously operates in both child and parent station modes by utilizing two distinct frequency bands, with a control unit managing channel switching between these bands to prevent interference, allowing seamless transitions between infrastructure and direct connection modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a communication apparatus operates in both child station mode and parent station mode simultaneously, then the convenience and functionality are improved, but interference between the two modes occurs due to frequency band conflicts
Solution Approach 1:
The patent divides the frequency spectrum into separate first and second frequency bands, assigning the first band to child station operations and the second band to parent station operations. This segmentation prevents interference between the two modes by ensuring they operate on different frequencies simultaneously.
Solution Approach 2:
The patent introduces a frequency band dimension to resolve the conflict between child station and parent station modes. By adding this spectral dimension for mode differentiation, the system enables concurrent operations that would otherwise interfere with each other in the time domain.
2Object-affected harmful factors
If a communication apparatus switches frequency bands between child and parent modes, then interference is prevented, but channel switching complexity increases
Solution Approach 1:
The patent pre-assigns specific frequency bands to specific modes (first band for child station, second band for parent station). This preliminary assignment simplifies the switching control by establishing a predetermined mapping between modes and frequency bands, reducing the complexity of real-time decision-making.
Solution Approach 2:
The communication apparatus automatically selects the appropriate frequency band based on its operational mode without requiring complex external coordination. The system self-manages the frequency band selection based on whether it is operating as a child station or parent station.
3Adaptability or versatility
If multiple apparatuses operate in concurrent modes, then the functionality is enhanced, but the management of frequency bands becomes more difficult leading to reduced convenience
Solution Approach 1:
The patent changes the frequency band parameter based on the operational mode. By dynamically adjusting which frequency band is used according to whether the apparatus is in child station or parent station mode, the system simplifies frequency band management while enabling concurrent operations.

AI summary
A communication apparatus is configured to perform control in such a manner that one of the first and second frequency bands is used in operating in a first mode and the other frequency band (of the first and second frequency bands) is used in operating in a second mode, during a time period in which the state in which the communication apparatus is operating in the first mode and the state in which the communication apparatus is operating in the second mode are concurrently maintained.
