Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless electric power supply techniques do not consider the varying electric power consumption of each receiving apparatus, leading to potential disruptions in communication processes due to inadequate power supply.
Innovation Solution
An electric power supply apparatus that acquires and distributes power based on the consumption of each receiving apparatus, prioritizing those with higher needs, using a combination of detection, communication, and timing control to ensure efficient power allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electric power is supplied equally to all receiving apparatuses in a time-sharing manner, then the power supply system is simple to implement, but communication apparatuses in active communication processes may not receive sufficient power and may stop their communication processes
Solution Approach 1:
The patent changes the parameter of power distribution from equal allocation to unequal allocation based on communication status. The base station identifies whether each terminal is in communication or waiting state and allocates power accordingly, giving higher power to communicating terminals and lower power to waiting terminals, thus ensuring communication continuity while maintaining system manageability
Solution Approach 2:
The patent implements a feedback mechanism where terminals report their communication status (communication or waiting state) to the base station. The base station uses this feedback information to dynamically adjust power allocation for each terminal in subsequent time slots, ensuring that power distribution matches actual needs and prevents communication interruptions
2Reliability
If more power is allocated to terminals in communication processes, then communication reliability is improved, but the power consumption of the base station increases
Solution Approach 1:
The patent dynamically changes the power allocation parameter based on the number and status of active communication terminals. When fewer terminals are in communication mode, the base station reduces total power consumption by allocating lower power to waiting terminals. When more terminals need communication, power is increased only for those specific terminals, optimizing the balance between communication reliability and energy efficiency
3Productivity
If the base station monitors and adjusts power for each terminal individually, then power distribution efficiency is optimized, but the signaling overhead and system complexity increase
Solution Approach 1:
The patent uses a simplified status parameter (communication or waiting state) to guide power allocation decisions. By categorizing terminals into these two states and using this single parameter for allocation, the system achieves efficient power distribution without requiring complex monitoring of detailed terminal operations, thus minimizing signaling overhead while maintaining productivity
Solution Approach 2:
The patent applies different power allocation strategies to different groups of terminals based on their local conditions. Terminals in communication status receive higher power allocation while waiting terminals receive lower power, creating a differentiated local quality approach that optimizes overall system efficiency without requiring uniform complex control across all terminals
