Solution Overview

Problem

Users face difficulties in tuning to new radio stations while traveling due to varying signal strengths and availability, and existing databases are cumbersome to maintain and often outdated, especially in areas with irregular broadcast coverage.

Innovation Solution

A crowd-sourced database system that collects and updates radio station information centrally, allowing clients to download only pertinent data for their route, enabling efficient tuning to new stations without constant network access and providing a graphical interface for selecting stations based on user preferences.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a complete database of radio station information is stored on the client device, then the user can access radio station data without network connection, but the storage requirement increases significantly

Engineering Contradiction:
Improveradio station data availabilityVSAvoidstorage space
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent divides the complete radio station database into multiple smaller files organized by geographic regions or routes. Instead of storing one large database on the client device, the system provides access to multiple segmented database files that can be downloaded selectively based on the user's location and travel route, significantly reducing storage requirements while maintaining data availability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a geographic dimension for organizing radio station data by location rather than storing all data uniformly. The system queries and retrieves only the database portions relevant to the user's current or planned location, transforming the data access pattern from complete local storage to selective geographic-based retrieval, thereby reducing storage needs while maintaining reliability.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If the radio station database is updated frequently to reflect signal strength changes and frequency adjustments, then the information remains current, but the maintenance complexity and time consumption increase

Engineering Contradiction:
Improvedatabase accuracyVSAvoiddatabase maintenance
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements a feedback mechanism where client devices automatically report their detected radio station information, signal strength, and location data back to the central server. This feedback loop enables the database to be continuously updated with real-world reception data without manual intervention, maintaining accuracy while reducing maintenance complexity through automated data collection and processing.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system enables self-service database maintenance by allowing the radio station database to update itself through automated queries to client devices and processing of reported data. The central server automatically incorporates new information from multiple client devices, eliminating the need for manual database updates and reducing maintenance time and complexity while ensuring the database remains current.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If the system provides detailed radio station coverage information for all areas, then the user can find stations anywhere, but the data size increases and much data may not be pertinent to the user's specific trip

Engineering Contradiction:
Improveradio station coverageVSAvoiddata size
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent applies local quality by providing radio station database information tailored to the user's specific location and travel route rather than uniform coverage data for all areas. The system queries and retrieves only the database portions relevant to the user's current or planned location, ensuring high-quality, relevant information is provided where needed while avoiding unnecessary data for areas the user will not visit.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system extracts and provides only the necessary radio station database portions relevant to the user's specific trip parameters (location, route, destination). Instead of delivering the complete database, the patent selectively extracts and transmits only the pertinent data segments that match the user's travel plans, significantly reducing data size while maintaining adaptability to the user's specific needs.

Inventive Principle:
Principle #2Taking out (Extraction)

4Adaptability or versatility

If the receiver scans through the entire radio spectrum to locate new stations, then all available stations can be found, but the user experiences time loss and may not efficiently locate stations matching their preferences

Engineering Contradiction:
Improvestation selectionVSAvoidsignal acquisition time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent implements preliminary action by pre-querying the radio station database for stations relevant to the user's current or planned location before the user needs to tune in. The system proactively provides a curated list of recommended stations based on geographic data and user preferences, eliminating the need for the user to manually scan the entire spectrum and significantly reducing signal acquisition time while maintaining versatile station selection.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary - the radio station database query system - that mediates between the user's location and the available radio stations. Instead of requiring the receiver to scan the entire spectrum, the database system acts as an intermediary that processes location information, filters relevant stations, and provides a targeted list of recommendations, thereby reducing search time while maintaining comprehensive station selection capabilities.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Implementing and applying a database with radio station information that is gathered from client devices as stations become available to a plurality of users (i.e., "crowd sourced" radio station information) and allowing for a client device to download only the radio station information that is pertinent to the travel route of the user and/or radio station selection criteria associated with the client device or the user. Radio station information can be rendered via a graphical interface of a client device to allow the user to informatively select a new radio station, either before or as a current radio signal degrades to the point of being unusable. Radio station information may be rendered to cause the user's terrestrial radio to tune to a new station.
