Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power supply systems for lamps lack accurate control over output state adjustments, as the feedback signals transmitted between the primary and secondary sides are not processed effectively, leading to inconsistencies in the working state.
Innovation Solution
A power supply system with a first controller on the primary side detecting and processing an adjustment signal, which is then transmitted to a second controller on the secondary side via an isolator, ensuring the quality of the signal and allowing accurate adjustment of the output state without the need for additional signal translation or encoding circuits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If feedback signals are transmitted between primary and secondary sides using existing isolation methods, then signal transmission is achieved, but control precision of output state is insufficient
Solution Approach 1:
The patent introduces an isolator as an intermediary component between the primary and secondary sides. The isolator includes a transformer that magnetically couples the two sides, allowing signal transmission while providing electrical isolation. This mediator enables precise control signals to be transmitted from the primary side controller to the secondary side controller without direct electrical connection, thus maintaining signal quality and control precision simultaneously.
Solution Approach 2:
The patent replaces direct electrical signal transmission with magnetic field-based signal transmission through the transformer. By using electromagnetic induction instead of direct electrical connection, the system achieves both signal transmission and electrical isolation, improving control precision while maintaining reliability through the physical isolation barrier.
2Reliability
If additional circuits for signal translation and encoding are added, then signal transmission between isolated sides is enabled, but device complexity increases
Solution Approach 1:
The isolator with transformer is designed to perform multiple functions simultaneously: it provides electrical isolation between primary and secondary sides, transmits control signals bidirectionally, and maintains signal integrity. This multi-functional component eliminates the need for separate translation and encoding circuits, reducing device complexity while ensuring reliable signal transmission.
Solution Approach 2:
The patent merges the isolation function and signal transmission function into a single transformer-based isolator component. By combining these functions that were previously performed by separate circuits, the system reduces overall device complexity while maintaining reliable signal transmission capability between the isolated sides.

AI summary
A power supply for a lamp is provided. An adjustment signal is detected and processed by a first controller (101) on a primary side, and the processed adjustment signal is transmitted to a second controller (102) on a secondary side via an isolator (103). Thus, the quality of the adjustment signal is ensured in the transmission, and the output state of the power supply may be adjusted accurately by the second controller (102) on the secondary side. Furthermore, no additional circuit for translating and encoding or decoding signals is needed.
