Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems require separate components for power transfer and data transmission, leading to inefficiencies and increased costs due to the need for multiple transformers or couplers, which complicates the design and increases space and expense.
Innovation Solution
A transformer-based system that enables both power transfer and bi-directional data communication using a single transformer, where a controller induces a rapidly rising current to open a data transmission window, allowing data to be transmitted during power transfer cycles, and employs echo operations to enhance efficiency and throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate components are used for power transfer and data transmission, then reliability is improved, but device complexity increases and cost increases
Solution Approach 1:
The patent combines power transfer and data transmission functions into a single transformer component. The transformer's primary and secondary windings are used simultaneously for both power coupling and bidirectional data communication, eliminating the need for separate transformers or couplers for each function.
Solution Approach 2:
The transformer is designed to perform multiple functions: it transfers power between circuits and simultaneously enables bidirectional data communication. The same magnetic coupling mechanism that transfers power also carries data signals, making the transformer a universal component for both power and data applications.
2Reliability
If separate components are used for power transfer and data transmission, then reliability is improved, but cost increases
Solution Approach 1:
The patent merges power transfer and data transmission into a single transformer component, reducing the total component count and associated costs. By using the same transformer for both functions, the system eliminates the need for additional transformers, couplers, or related components that would increase manufacturing cost.
Solution Approach 2:
The transformer serves as a universal component for both power and data applications, maximizing its utility and reducing the need for specialized components. This multi-functionality approach reduces overall system cost by eliminating redundant components and simplifying the bill of materials.
3Device complexity
If a single transformer is used for both power transfer and data transmission, then device complexity is reduced and cost is reduced, but data transmission rate may be affected
Solution Approach 1:
The system uses periodic switching between power transfer mode and data transmission mode. During data transmission, the transformer operates in a high-frequency switching regime that allows data signals to be superimposed on the power transfer waveform, enabling high-speed communication while maintaining power transfer capability.
Solution Approach 2:
The system dynamically changes operating parameters to optimize for different functions. During data transmission, the switching frequency and duty cycle are adjusted to maximize data rate while maintaining sufficient power transfer. The controller modifies these parameters in real-time to balance power and data performance.

This approach eliminates the need for separate couplers, achieving space and cost savings while enabling efficient power transfer and high-speed data communication through a single transformer, improving both power efficiency and data transmission rates.
Implementation Method 1
A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. A varying current in one winding (e.g., inductor or coil) of the transformer produces a varying magnetic field, which in turn induces a voltage in a second winding.
Implementation Method 2
The primary controller coupled to intermittently cause a short at the primary winding to indicate a transmission of data to the secondary controller via the transformer
