Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Voltage supplied to multiple loads decreases due to wiring resistance, resulting in varying voltages across loads, and existing solutions fail to maintain voltages within an allowable range during fluctuations.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wiring resistance is reduced to maintain voltage, then voltage stability improves, but wiring complexity and device layout constraints increase
Solution Approach 1:
The patent implements a feedback mechanism where the feedback portion monitors the voltage at the output terminal and adjusts the power source circuit's output accordingly. This closed-loop control compensates for voltage drops caused by wiring resistance, maintaining stable voltages across all loads without requiring complex wiring redesign or reduced wiring paths.
2Reliability
If feedback control is added to adjust output voltage, then voltage uniformity across loads improves, but device complexity increases
Solution Approach 1:
The feedback portion compares the actual output voltage with the target voltage and generates an error signal that adjusts the power source circuit's output. This feedback control mechanism ensures uniform voltage distribution across multiple loads while maintaining a relatively simple circuit structure by using standard control components.
Solution Approach 2:
The feedback portion acts as an intermediary between the output terminal and the power source circuit, translating voltage deviations into corrective control signals. This mediator approach enables precise voltage regulation without directly modifying the power source circuit's internal structure, thus adding minimal complexity.
3Measurement precision
If wiring resistance is increased for the feedback path, then feedback signal accuracy improves, but power loss increases
Solution Approach 1:
The patent applies different wiring resistance characteristics to different parts of the circuit: the feedback path uses higher resistance wiring to improve noise immunity and signal accuracy, while the main power delivery paths use low-resistance wiring to minimize power loss. This localized optimization of wiring properties resolves the contradiction between feedback accuracy and power efficiency.

AI summary
An electronic module includes a plurality of loads, a first wiring portion, a second wiring portion, a power source unit, and a feedback portion. The first wiring portion includes a plurality of first portions to which the plurality of loads are respectively connected, and a plurality of second portions each closest to a corresponding one of the plurality of first portions. The second wiring portion is connected to the plurality of second portions. The power source unit includes a feedback terminal, an output terminal, and a power source circuit. In the first wiring portion, a minimum path length from each of the plurality of second portions to the corresponding one of the plurality of first portions is smaller than 1/2 of a minimum path length from a part of the first wiring portion connected to the output terminal to the corresponding one of the plurality of first portions.
