Mobile Partition Wall Voltage Drop Elimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile partition walls face limitations due to high voltage drops caused by relays, which restrict the number of wall elements that can be supplied with a voltage source, making it difficult to efficiently manage and control multiple independently displaceable wall elements.
Innovation Solution
The solution involves separating the voltage supply and signaling for activating control units and motors, using a parallel electrical connection for control units and a signaling element to trigger unlocking signals, eliminating the need for relays and allowing for the supply of multiple control units with a single voltage source. This includes a signaling element with plug-in connections for communication between wall elements and a microcomputer for controlling the movement of connection profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If relays are used to sequentially supply voltage to control units of wall elements, then the electrical connection can be established through all wall elements, but the voltage drop becomes high which limits the number of supplyable wall elements
Solution Approach 1:
The patent separates the voltage supply function from the signaling function. Control units are connected in parallel to the voltage source for simultaneous power supply, while separate signaling elements (contactless sensors) transmit unlocking signals sequentially. This segmentation eliminates the cumulative voltage drop problem of series relay connections while maintaining reliable control.
Solution Approach 2:
The patent introduces contactless signaling elements (such as optical or radio frequency communicators) as intermediaries between wall elements. These signaling elements transmit unlocking signals without electrical contact, avoiding the voltage drop associated with relay-based electrical connections while ensuring reliable signal transmission across multiple wall elements.
2Ease of operation
If relays are used for sequential voltage supply, then control can be achieved across wall elements, but the number of wall elements that can be supplied is limited
Solution Approach 1:
The patent divides the control system into two independent subsystems: a parallel voltage supply subsystem that can power any number of control units simultaneously, and a sequential signaling subsystem that maintains controlled operation. This allows the system to scale to any number of wall elements without the limitations imposed by relay-based voltage distribution.
3Loss of energy
If control units are connected in parallel for simultaneous voltage supply, then voltage drop is reduced, but sequential activation of wall elements must be achieved through separate signaling
Solution Approach 1:
The patent employs contactless signaling elements as mediators between adjacent wall elements. These elements detect the position and movement of connection profiles and transmit unlocking signals sequentially through the parallel-connected control units, enabling controlled operation without complex electrical switching networks.
