Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication apparatuses face challenges in improving convenience as usage patterns diversify, particularly in efficiently managing wireless communication modes and frequency bands between devices with and without relay apparatuses.
Innovation Solution
A communication apparatus that can switch between wireless communication modes via a relay apparatus and direct communication, with a control unit managing frequency bands to avoid interference by setting different parts of the frequency bandwidth for each mode, ensuring seamless operation in both infrastructure and peer-to-peer modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless communication is performed in both first mode (via relay apparatus) and second mode (direct communication) using the same frequency band, then communication versatility is improved, but communication interference occurs between the two modes
Solution Approach 1:
The frequency band used for wireless communication is divided into multiple frequency sub-bands. The control unit allocates different frequency sub-bands to the first mode (infrastructure mode via relay apparatus) and the second mode (direct communication mode), thereby segmenting the frequency resources to avoid interference between the two communication modes while maintaining versatility in using both modes simultaneously
2Device complexity
If the same frequency band is allocated to both communication modes, then frequency resource utilization is simplified, but communication reliability deteriorates due to interference
Solution Approach 1:
The frequency band is segmented into multiple frequency sub-bands, with each sub-band allocated to specific communication modes. This segmentation approach maintains relatively simple frequency management through automated control unit allocation while significantly improving communication reliability by eliminating interference between concurrent communication modes operating in different sub-bands
3Productivity
If frequency bands are dynamically allocated to different communication modes, then communication performance is improved, but control complexity increases
Solution Approach 1:
The control unit automatically performs frequency sub-band allocation for different communication modes based on the operational state and requirements of each mode. This self-service mechanism dynamically optimizes communication efficiency by allocating appropriate frequency resources without requiring external intervention or complex manual configuration, thereby improving productivity while keeping the control system self-managing rather than externally complex
