Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital receiving systems for simultaneous information and energy transfer dissipate energy from analog signals during conversion, leading to insufficient energy supply and communication interruptions.
Innovation Solution
A digital receiving system that converts serial SIET analog signals to parallel, separates and processes information and energy signals differently, with analog-to-digital conversion for information and energy demodulation, rectification, and storage in separate domains to preserve energy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If analog-to-digital conversion is performed on the received analog signal in existing digital receiving systems, then communication reliability is improved, but energy is dissipated in the form of heat and insufficient energy is provided to the receiving terminal
Solution Approach 1:
The patent segments the received analog signal into two separate paths: one for information processing (analog-to-digital conversion) and one for energy harvesting (energy signal processing unit). This segmentation allows the information signal to be converted to digital form for reliable processing while the energy signal is routed to a separate unit that rectifies and stores it, preventing energy dissipation as heat.
Solution Approach 2:
The patent introduces an energy signal processing unit as an intermediary component between the analog signal reception and the power supply system. This intermediary unit specifically processes the energy-containing portion of the analog signal through rectification and storage, acting as a mediator that captures and preserves energy that would otherwise be lost during standard analog-to-digital conversion.
2Use of energy by moving object
If the energy signal is processed in analog domain through energy demodulation, parallel-to-serial conversion, decoding and rectification, then full energy collection is enabled, but device complexity increases
Solution Approach 1:
The patent divides the receiving system into distinct functional modules: an information signal processing unit for digital communication and an energy signal processing unit for energy harvesting. Each unit handles specific tasks independently, which虽然 increases component count but organizes complexity into manageable, specialized segments rather than a monolithic complex system.
Solution Approach 2:
The receiving system is designed with multi-functionality, where the same received analog signal serves dual purposes: information transmission (processed through analog-to-digital conversion and demodulation) and energy transmission (processed through energy demodulation and rectification). This universal approach allows a single receiving system to simultaneously perform both communication and power harvesting functions.

AI summary
A method is provided for digital Simultaneous Information and Energy Transfer (SIET), comprising the steps of receiving a serial SIET analog signal, and converting the serial SIET analog signal received into a parallel SIET analog signal, extracting an analog information signal and an analog energy signal from the parallel SIET analog signal, performing analog-to-digital conversion on the analog information signal to obtain a digital information signal, and performing information demodulation, parallel-to-serial conversion and decoding on the digital information signal in digital domain, and pre-processing the analog energy signal in analog domain and storing the preprocessed analog energy signal. As the information signal is processed in the digital domain and the energy signal is processed in the analog domain, the energy in the SIET signal can be full collected in receiving side.
