Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional magnetic switches, such as reed switches, require manual operation with a magnetic rod for activation, which is inconvenient and results in low on rates due to inaccuracy in on distance control, making them less suitable for small-sized sensor products.
Innovation Solution
A system comprising a switch control unit and a control signal receiving unit that generates or eliminates a magnetic field based on a pulse signal, using a current coil to activate the magnetic switch, allowing for remote control and improved accuracy through coded data generation and adjustment of sensing parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a magnetic rod is used to manually approach and activate the reed switch, then the switch can be turned on, but the operation is inconvenient and the on rate is low due to inaccuracy in distance control
Solution Approach 1:
The patent replaces the manual mechanical operation of bringing a magnetic rod close to the reed switch with an electromagnetic field generated by a coil. The controller activates the coil through pulse signals, creating a magnetic field that remotely triggers the reed switch without requiring manual proximity operations, thereby improving both convenience and reliability
Solution Approach 2:
The patent introduces a coil as an intermediary component between the controller and the reed switch. The coil converts electrical pulse signals from the controller into magnetic fields that activate the reed switch, serving as a mediator that enables reliable remote activation without direct manual intervention
2Ease of operation
If a coil is used to generate magnetic field for remote control, then operation convenience is improved, but the device complexity increases
Solution Approach 1:
The patent integrates the coil and controller into a unified control unit that serves multiple functions: generating control signals, producing magnetic fields, and activating the reed switch. This multi-functional design reduces overall system complexity despite adding remote control capability
Solution Approach 2:
The patent combines the controller and coil into an integrated control unit, merging multiple components into a single assembly. This consolidation simplifies the overall device structure while maintaining the remote control functionality through coordinated operation of the integrated components

AI summary
A system for controlling a magnetic switch in urinals includes a switch control unit and a control signal receiving unit connected to the switch control unit via a magnetic field. The switch control unit is configured to generate and eliminate the magnetic field based on a received pulse signal. The control signal receiving unit outputs an on signal in response to sensing the generation of the magnetic field and outputs an off signal in response to sensing the elimination of the magnetic field.
