Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If multiple RF apparatuses are coupled to provide additional signal paths, then the number of available signal paths increases, but the cost and complexity of the measurement setup increases

Engineering Contradiction:
Improvenumber of signal pathsVSAvoidcomplexity of measurement setup
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

A transceiver module is introduced as an intermediary device between the RF apparatus and multiple RF devices. The transceiver module includes a baseband interface connected to the RF apparatus, multiple RF interfaces connected to different RF devices, and a switching unit that dynamically routes baseband signals to appropriate RF interfaces. This intermediary solution allows one RF apparatus to control multiple RF devices without requiring multiple RF apparatuses, thereby increasing signal path quantity while maintaining setup simplicity and reducing cost.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The transceiver module serves multiple functions: it acts as a baseband processor, an RF signal generator, a signal router, and a device controller all in one unit. By making the transceiver module universal and multi-functional, the system replaces the need for multiple specialized RF apparatuses, thus increasing the number of available signal paths without proportionally increasing system complexity or cost.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Quantity of substance

If multiple RF apparatuses are coupled to provide additional signal paths, then the number of available signal paths increases, but the cost of the measurement setup increases

Engineering Contradiction:
Improvenumber of signal pathsVSAvoidcost of measurement setup
Core Design Contradiction:
Quantity of substanceVSEase of manufacture

Solution Approach 1:

The transceiver module merges the functions of multiple RF apparatuses into a single integrated device. By combining baseband processing, RF signal generation, signal routing, and device control capabilities into one transceiver module, the system achieves multiple signal paths without the cost penalty of purchasing and integrating multiple separate RF apparatuses. This merging approach directly addresses the cost issue while maintaining the desired increase in signal path quantity.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If the RF apparatus hardware is adapted to provide additional interfaces, then the number of connectable RF devices increases, but the hardware adaptation cost increases

Engineering Contradiction:
Improvenumber of connectable RF devicesVSAvoidhardware adaptation cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The invention extracts the additional interface functionality from the RF apparatus itself and places it in a separate transceiver module. Instead of modifying the RF apparatus hardware to add more interfaces, the transceiver module is connected to the existing RF apparatus via a baseband interface and provides multiple RF interfaces to connect to additional RF devices. This extraction approach increases adaptability while avoiding expensive hardware modifications to the original RF apparatus.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The transceiver module acts as an intermediary that extends the connectivity of the RF apparatus without requiring modifications to the RF apparatus itself. The module receives baseband signals from the RF apparatus through the baseband interface and provides multiple RF output interfaces to connect to multiple RF devices, thereby increasing the number of connectable devices without incurring hardware adaptation costs.

Inventive Principle:
Principle #24Intermediary (Mediator)
