Solution Overview
Problem
Conventional radio communication devices using press-to-talk systems lack flexible volume adjustment capabilities, leading to potential missed important information due to uniform volume settings regardless of the communication source, which can be inappropriate for different situations.
Innovation Solution
A radio communication device and method that adjusts volume based on source information acquired during user operations, utilizing an adjustment coefficient and associated information table to customize volume levels for different sources, allowing flexible volume control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If uniform volume setting is used for all communication sources, then device complexity is reduced and operation is simplified, but adaptability to different communication situations deteriorates
Solution Approach 1:
The patent segments the volume control function by creating separate volume settings for different communication sources (e.g., PTT transmission, automatic reception from different sources). This allows each source to have independent volume adjustment, improving adaptability without requiring a completely new complex system. The volume adjusting unit divides the overall volume control into source-specific segments.
Solution Approach 2:
The system automatically identifies the communication source and applies the appropriate volume setting without requiring manual user intervention for each source. The volume adjusting unit self-services by automatically selecting and applying the correct volume level based on the detected source, simplifying operation while maintaining adaptability.
2Object-affected harmful factors
If volume is lowered for all received voices, then harmful factors from unwanted voices are reduced, but important information may be lost
Solution Approach 1:
The patent applies different volume adjustment qualities to different communication sources. Wanted voices (e.g., from authorized sources or specific groups) maintain their original volume or are boosted, while unwanted voices have their volume reduced. This local differentiation allows the system to reduce harmful factors from unwanted voices without losing important information from wanted sources.
Solution Approach 2:
The system uses source information as feedback to determine the appropriate volume adjustment. By continuously monitoring the communication source and comparing it against predefined criteria or user preferences, the volume adjusting unit can dynamically adjust volume levels to suppress unwanted voices while preserving important information.
3Loss of information
If volume is increased for all received voices, then important information is ensured to be heard, but unwanted voices also become more audible
Solution Approach 1:
The patent applies selective volume enhancement only to wanted communication sources while maintaining or reducing volume for unwanted sources. This localized quality adjustment ensures that important information from authorized sources is heard clearly without amplifying disturbance from unwanted voices.
Solution Approach 2:
The system uses source identification feedback to determine which voices should be enhanced. By continuously monitoring and identifying the communication source, the volume adjusting unit can selectively increase volume for important information while suppressing unwanted voices.
4Measurement precision
If manual volume adjustment is required for each communication situation, then volume control precision is improved, but ease of operation deteriorates
Solution Approach 1:
The system provides self-service volume adjustment by automatically detecting the communication source and applying the appropriate volume setting. This eliminates the need for manual adjustment in each situation, maintaining precision through automatic source-based selection while significantly improving ease of operation.
Solution Approach 2:
The system uses real-time feedback from source identification to automatically adjust volume precision. By continuously monitoring the communication source and comparing it against stored source information, the system achieves precise volume control without requiring manual user input for each situation.

AI summary
A radio communication device is a radio communication device that performs radio communication by a press-to-talk communication system, and includes an operating unit that receives an operation of a user, an output unit that outputs a received voice signal as a voice, and a volume adjusting unit that adjusts a volume of the voice output by the output unit. The volume adjusting unit acquires source information that indicates a source of the voice signal when a predetermined operation by a user is made with respect to the operating unit, and adjusts the volume of the voice by using an adjustment coefficient that is a degree of adjustment of the volume of the voice, based on the acquired source information.
