Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a wireless station is equipped with multiple PTT switches for switching between different frequency bands and telecommunication standards, then the adaptability to different communication scenarios is improved, but the device complexity and ease of operation deteriorate

Engineering Contradiction:

Improveadaptability to different communication scenariosVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The wireless station automatically determines its own geographical location using a position determiner and autonomously selects the appropriate telecommunication mode based on the determined location, eliminating the need for manual intervention by the operator to switch between different communication modes

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system pre-configures multiple telecommunication modes corresponding to different geographical areas, and the position determiner proactively determines the current location before communication begins, allowing the mode selector to automatically configure the appropriate communication mode in advance

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If a wireless station is equipped with multiple PTT switches for switching between different frequency bands and telecommunication standards, then the adaptability to different communication scenarios is improved, but the ease of operation worsens

Engineering Contradiction:

AI summary

A wireless station (1) includes a switching instruction acceptor (11), a position determiner (12), a mode selector (13), a signal processing circuit (14), and a communicator (15). The position determiner (12) determines, with respect to at least one area that indicates a geographical range associated with one of telecommunication modes of the wireless station (1), whether or not the wireless station is located within one of the areas. When the switching instruction acceptor (11) accepts an instruction of switching to a transmission mode, the mode selector (13) selects a first telecommunication mode of an area within which the wireless station (1) is determined to be located or a second telecommunication mode in a case where the wireless station is not located within any of the areas. The signal processing circuit (14) generates, from an input signal, transmission data matching a telecommunication mode selected by the mode selector (13).
