Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication apparatuses face challenges in maintaining stable electric power levels for continuous operation, leading to potential disruptions in data transmission due to uneven power distribution and reliance on battery replacement or energy harvesting, which may not provide constant and stable power.
Innovation Solution
A wireless communication apparatus with an electric power storage section, wireless communication section, and control section that manages electric power distribution among devices based on priority levels, ensuring that each device maintains the necessary power level for operation by transferring power from devices with surplus to those in need, using the required power level for operation as a threshold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If electric power is distributed equally among wireless communication apparatuses, then the electric power storage levels even out, but it becomes difficult to guarantee the operation of each apparatus
Solution Approach 1:
The patent assigns different priority levels to different wireless communication apparatuses based on their specific operational requirements. High-priority apparatuses receive preferential power distribution to ensure their continuous operation, while low-priority apparatuses receive power only when surplus is available. This local differentiation of power allocation quality resolves the contradiction by ensuring critical devices maintain operation while still distributing power across the network.
Solution Approach 2:
The control section continuously monitors the electric power storage levels of all apparatuses and dynamically adjusts power distribution decisions based on real-time conditions. When a high-priority apparatus's power level drops below a threshold, the system responds by prioritizing power transfer to that apparatus. This feedback mechanism ensures operational reliability while maintaining overall power balance.
2Ease of operation
If electric power is distributed to even out storage levels, then fairness is achieved, but transmission disruptions occur when apparatuses run out of power
Solution Approach 1:
The system implements differentiated power distribution where high-priority apparatuses receive preferential treatment to ensure continuous transmission operation. The control section identifies apparatuses with low power levels that have high priority and directs power transfers to them first, ensuring their transmission operations are not disrupted. This local quality approach maintains fairness while preventing transmission disruptions for critical devices.
Solution Approach 2:
The control section continuously monitors both power storage levels and priority levels of all apparatuses. When transmission disruptions are detected or predicted (power level dropping below threshold), the system responds by adjusting power distribution to prioritize affected apparatuses. This feedback loop ensures continuous operation while maintaining fair overall distribution.
3Ease of manufacture
If energy harvesting is used to eliminate batteries, then battery replacement is eliminated, but constant and stable power generation is difficult to achieve
Solution Approach 1:
The patent combines energy harvesting technology with wireless power transfer technology in a hybrid power supply system. The energy harvesting section collects ambient energy (solar, wind, vibration) to generate electric power, while the wireless power transfer section supplements power deficits by receiving energy from other apparatuses. This merging of two power sources achieves both the elimination of battery replacement and stable, constant power generation.
Solution Approach 2:
The control section acts as an intermediary that manages the unstable output from energy harvesting by coordinating with the wireless power transfer system. When energy harvesting produces insufficient or unstable power, the control section activates power reception from other apparatuses to stabilize the overall power supply. This intermediary management resolves the instability issue while maintaining the battery-less design.

AI summary
Electric power is distributed among wireless communication apparatuses while, at the same time, an electric power level required to operate a wireless communication function in the wireless communication apparatus is maintained. A wireless communication apparatus includes an electric power storage section, a wireless communication section, and a control section. The electric power storage section stores electric power. The wireless communication section engages in wireless communication with other wireless communication apparatuses by using the electric power stored in the electric power storage section. The control section controls passing of electric power stored in the electric power storage section by using the electric power level required to operate a wireless communication section as a threshold. At this time, the control section performs control such that electric power is passed to or from other wireless communication apparatuses according to a priority level assigned to each of the wireless communication apparatuses.
