Engineering Contradiction Analysis
1Object-affected harmful factors
If transmitting power is reduced to mitigate interference and packet collisions, then radio wave interference and packet collisions are reduced, but connectivity of wireless communication may not be maintained
Solution Approach 1:
The patent applies dynamics by making the transmitting power adjustable rather than fixed. The transmitting power control unit dynamically changes the transmitting power level based on real-time network conditions, specifically the number of neighboring wireless communication apparatuses detected. This allows the system to adapt between high power (for connectivity) and low power (for reduced interference) depending on the operational context.
Solution Approach 2:
The patent implements parameter changes by modifying the transmitting power parameter according to the density of neighboring wireless communication apparatuses. When many neighbors are detected, the system switches to a first (lower) transmitting power to reduce interference and packet collisions. When fewer neighbors are detected, it switches to a second (higher) transmitting power to maintain connectivity, thus changing the power parameter based on environmental conditions.
2Object-affected harmful factors
If transmitting power is reduced to mitigate interference and packet collisions, then radio wave interference and packet collisions are reduced, but dissipation power of wireless communication apparatus is reduced
Solution Approach 1:
The patent changes the transmitting power parameter based on the number of neighboring wireless communication apparatuses. In high-density areas where packet collisions are frequent, the system reduces transmitting power to minimize collisions and associated retransmissions, thereby reducing overall energy dissipation. In low-density areas, higher power is used but less frequently, optimizing the balance between communication reliability and energy consumption.
Solution Approach 2:
The patent converts the potentially harmful effect of high transmitting power (which causes packet collisions and retransmissions) into a benefit by reducing power in dense areas. This reduction prevents the harmful cycle of collisions and retransmissions that would consume more energy, thus transforming the power reduction from a potential connectivity risk into an energy-saving measure that also reduces packet collisions.
3Object-affected harmful factors
If transmitting power is reduced to mitigate interference and packet collisions, then radio wave interference is reduced, but range of access of radio waves is reduced
Solution Approach 1:
The patent applies dynamics by making transmitting power adaptable rather than static. The system dynamically adjusts power levels based on the detected number of neighboring wireless communication apparatuses, switching between low power (first transmitting power) in dense areas to reduce interference, and high power (second transmitting power) in sparse areas to extend range of access.
Solution Approach 2:
The patent implements local quality by applying different transmitting power levels to different local conditions. In areas with many neighboring apparatuses (high density), the system uses lower transmitting power locally to reduce interference. In areas with fewer neighbors (low density), it uses higher transmitting power locally to maintain adequate range of access. This localized adaptation resolves the contradiction between reducing interference and maintaining range.

AI summary
A wireless communication apparatus having a plurality of neighboring wireless communication apparatuses may includes a wireless transmitter, an information control storage member, and a transmitting power calculator. A wireless transmitter may transmit a wireless signal with a transmitting power to a destination wireless communication apparatus. An information control storage member may maintain first information of links between the wireless communication apparatus and the plurality of neighboring wireless communication apparatuses, and second information of a communication route between the wireless communication apparatus and the destination wireless communication apparatus. A transmitting power calculator may calculate the transmitting power based on the first and second information, so as to ensure reception of the wireless signal.
