Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional radio communication devices using the TDMA method are not applicable to other multiple access methods like CDMA, FDMA, and CSMA/CA, and deactivate unnecessary operations to avoid noise, leading to inefficiencies in noise radiation and receiving sensitivity.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the radio communication device adopts a TDMA method to deactivate control unit operations during receiving slots, then noise radiation is reduced and receiving sensitivity is maintained, but the device becomes inapplicable to other multiple access methods (CDMA, FDMA, CSMA/CA)
Solution Approach 1:
The patent implements dynamic control of interface operations based on real-time received field strength measurements. The control unit adjusts interface activation states according to actual radio communication conditions rather than following fixed TDMA schedules, enabling the system to adapt to different multiple access methods while maintaining noise reduction benefits
Solution Approach 2:
The patent changes the control parameter from fixed time-based deactivation (TDMA slot) to field strength-based deactivation. By monitoring received field strength and comparing it against threshold values, the system dynamically determines when to deactivate interfaces, making it applicable to various multiple access methods while maintaining receiving sensitivity
2Reliability
If the radio communication device deactivates operations of LCD driver and I/O control unit to avoid noise, then receiving sensitivity is improved, but operations of control units free from noise influence are also deactivated
Solution Approach 1:
The patent applies local quality control by individually assessing each interface's noise impact characteristics. Instead of deactivating all non-essential interfaces uniformly, the system identifies specific interfaces that generate significant noise during receiving slots and deactivates only those, while maintaining operations of interfaces that do not interfere with receiving sensitivity
Solution Approach 2:
The patent implements feedback control by continuously monitoring received field strength and using this information to adjust interface activation states. The control unit receives field strength information, compares it against threshold values, and dynamically activates or deactivates interfaces based on actual noise conditions, ensuring optimal balance between noise reduction and operational efficiency
