1Adaptability or versatility

If preset tuning parameters are used in conventional vehicle radio receivers, then the device complexity is reduced and ease of operation is improved, but the adaptability to different signal reception conditions deteriorates

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A remote server acts as an intermediary between multiple radio receivers and the environment. The server collects signal reception data from various vehicles, processes this information, and generates optimized tuning parameters that are then distributed back to the receivers. This mediator approach allows individual receivers to achieve high adaptability without each one needing complex local processing capabilities.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

Instead of each radio receiver independently analyzing and adapting to signal conditions, the system creates a centralized copy of the environmental and signal data on the remote server. The server processes this copied data and generates tuning parameters that are then distributed to all receivers, eliminating the need for complex local adaptation mechanisms in each device.

Inventive Principle:

Principle #26Copying

2Reliability

Solution Approach 1:

The remote server serves multiple functions: collecting data from numerous receivers across different locations, processing this diverse information, and generating universally applicable tuning parameters. This multi-functional approach allows the system to cover diverse signal conditions without requiring complex manual testing procedures, as the server automatically processes data from real-world operations.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system implements a feedback loop where signal reception data from various vehicles is continuously collected, processed on the remote server, and used to generate updated tuning parameters that are distributed back to the receivers. This automated feedback mechanism ensures comprehensive coverage of diverse signal conditions without requiring manual field-testing operations.
