Venetian Blind Motor Control Over a Two-Wire Power Line
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Venetian blind driving systems require additional electronic devices and wires for complex drive controls, leading to increased installation time and cost, especially when integrated in insulated glazing, where additional holes are needed for wiring.
Innovation Solution
A method that uses a two-wire power line for signal communication between the blind assembly and control unit, enabling complex drive controls like Sun Tracking and firmware updates without additional connection wires, through data and current signal processing on the existing power line.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional electronic devices and wires are added for complex drive controls, then control functionality is improved, but device complexity and installation difficulty increase
Solution Approach 1:
The existing two-wire power line is made multi-functional by enabling it to carry both power delivery and bidirectional data communication. The blind assembly electronic means can both send data signals up the power line to the control unit and receive control signals down the power line, allowing complex controls without additional wiring infrastructure
Solution Approach 2:
The patent merges the power delivery function and data communication function into a single two-wire system. By superimposing data signals on the power lines and using the same physical infrastructure for both energy and information transfer, the system eliminates the need for separate communication wires
