Multi-Dimmer Control for Large-Load Power Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dimming control methods for KNX bus systems are inflexible, leading to mismatches between dimmer power and load power, which can result in inefficient control of multiple loads.
Innovation Solution
An apparatus and method that includes an on-off control circuit, dimmers with dimming control units, detection units, and switch units, allowing for reliable control of multiple dimmers to simultaneously deliver voltage to loads with large power by detecting live wire voltage thresholds and generating turn-on indication signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If single-channel control manner is used, then power of controlled load can be relatively large, but only one group of loads can be controlled
Solution Approach 1:
The patent combines multiple dimmers into a single multi-channel dimming control device, where each dimmer channel can independently control a group of loads. The control unit integrates multiple dimming control functions, allowing simultaneous control of multiple load groups while maintaining the ability to handle large power loads through parallel channel operation.
2Adaptability or versatility
If multi-channel control manner is used, then multiple groups of loads can be controlled, but power of each group of loads is relatively small
Solution Approach 1:
The patent segments the control system into multiple independent dimmer channels, each capable of handling substantial power loads. Each channel includes its own dimming control unit, detection unit, and execution unit, allowing independent control of large power loads while simultaneously managing multiple load groups through the segmented channel architecture.
3Ease of operation
If existing dimming control method is used, then control can be implemented, but flexibility is insufficient causing mismatch between dimmer power and load power
Solution Approach 1:
The patent implements dynamic power matching through detection units that monitor load power characteristics in real-time. The dimming control unit dynamically adjusts dimmer parameters based on detected load conditions, ensuring optimal matching between dimmer output capacity and actual load requirements. This dynamic adaptation provides both flexibility in controlling different load types and reliability through precise power matching.
