Automated Fixture Actuator Using Magnetic Alignment and Rack-and-Pinion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for adding automated or remote control functionality to pre-existing fixtures often require physical replacement, modification, or disassembly, which deter consumer adoption due to the need for electrical connections and unwillingness to modify existing setups.
Innovation Solution
An automation device that allows wireless and remote actuation of pre-existing fixtures with minimal installation and alignment, using magnets and self-affixing modalities, and incorporates a rack and pinion mechanism with a servomechanism for toggle-type switches and a rotational mechanism for rocker-type switches, along with Bluetooth Low Energy for wireless control and a microcontroller for smart features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If physical replacement or modification of existing fixtures is used to add automated control functionality, then automation capability is improved, but installation complexity and electrical connection requirements increase
Solution Approach 1:
The automation device is nested within the existing fixture structure. The actuator is positioned inside the fixture housing, the lever is inserted through the front opening, and all components are contained within the existing fixture boundaries, allowing automation to be added without replacing the entire fixture assembly
Solution Approach 2:
The automation device is divided into separate functional modules: a motorized actuator mechanism, a lever component, a control circuit board, and a battery compartment. This segmentation allows for easier installation and maintenance while maintaining full automation capability
2Extent of automation
If existing fixtures are modified to add automation, then automation functionality is improved, but risk of electrical shock and exposure to wiring increases
Solution Approach 1:
The device incorporates an integrated battery power system that operates independently of the fixture's electrical wiring. The battery compartment contains rechargeable cells that power the motorized actuator, control circuitry, and wireless communication modules, eliminating the need to expose or connect to internal wiring
Solution Approach 2:
A wireless communication module serves as an intermediary between the user and the automation device. Commands are transmitted wirelessly via Bluetooth or Wi-Fi to the control circuit board, which then activates the appropriate actuator mechanism, eliminating the need for physical electrical connections during installation or operation
3Extent of automation
If automation device is installed on existing fixture, then remote control capability is improved, but alignment precision and installation time are affected
Solution Approach 1:
The device incorporates adjustable mounting brackets and flexible positioning mechanisms that allow the actuator and lever to be dynamically positioned during installation. The mounting brackets can be adjusted in multiple directions to accommodate variations in fixture geometry, eliminating the need for precise pre-alignment
Solution Approach 2:
The actuator mechanism includes adjustable stroke length and force parameters. The motorized actuator can be programmed with different movement ranges and activation forces to match various lever types (toggle, rocker, slide), allowing the same device to work precisely with different fixture configurations without physical modification
4Extent of automation
If existing fixture is replaced entirely to add automation, then automation performance is improved, but cost and loss of existing fixture increase
Solution Approach 1:
The automation device is designed as a universal platform that can be installed on multiple types of existing fixtures including toggle switches, rocker switches, slide dimmers, and rotary controls. The adjustable actuator mechanism and programmable control system allow a single device design to serve multiple functions across different fixture types, preserving existing fixtures while adding automation capability
