Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current signal boosters face challenges in effectively amplifying and filtering signals across multiple frequency-contiguous bands, leading to interference and reduced network performance due to inadequate filter isolation and overlapping frequency ranges.
Innovation Solution
The use of physically isolated signal boosters within a single device, each configured to amplify and filter specific frequency bands, with controllers to adjust gain based on received signal strength and perform network protection, mitigates interference by employing band pass filters and intermediate frequency filters to enhance frequency selectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single signal booster amplifies multiple frequency bands, then the device complexity is reduced, but filter isolation becomes inadequate and interference increases
Solution Approach 1:
The patent divides the signal booster into multiple physically isolated units, with each unit dedicated to amplifying a specific frequency band. This segmentation prevents frequency interference between bands while maintaining manageable device complexity through modular architecture.
Solution Approach 2:
The patent introduces intermediate frequency filters as mediators between different frequency bands. These filters act as intermediaries that selectively pass desired frequencies while blocking interfering frequencies, enabling multi-band operation with adequate isolation.
2Adaptability or versatility
If signal boosters amplify signals across contiguous bands, then frequency coverage is expanded, but filter isolation becomes insufficient and network performance degrades
Solution Approach 1:
By segmenting the signal boosting function across multiple physically isolated units, each tuned to specific frequency bands, the system achieves broad frequency coverage while maintaining reliable network performance through prevented inter-band interference.
Solution Approach 2:
Each signal booster unit is optimized with local quality characteristics specific to its assigned frequency band, including band-specific filtering and amplification parameters. This localized optimization ensures reliable performance across the entire frequency spectrum while maintaining isolation between bands.
3Object-affected harmful factors
If physically isolated signal boosters are used for each frequency band, then interference is reduced, but device complexity increases
Solution Approach 1:
The patent accepts increased device complexity as a necessary trade-off for signal integrity, implementing physically isolated signal booster units for each frequency band to eliminate interference, with the modular structure managing the complexity burden.
4Object-affected harmful factors
If band pass filters and intermediate frequency filters are used, then frequency selectivity is enhanced and interference reduced, but device complexity increases
Solution Approach 1:
The patent employs intermediate frequency filters as mediators that convert high-frequency signals to intermediate frequencies for processing. This intermediary approach enhances frequency selectivity and noise rejection while managing device complexity through systematic signal transformation.
