Multistate Light Switch Control for Retrofit Lighting Sites
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-ceiling electronic devices in homes and buildings are difficult to install, require professional assistance, and lack flexibility in placement, especially after construction, due to structural interference and the need for rewiring.
Innovation Solution
A system utilizing modular application units that can be retrofitted into existing lighting sites, combined with multistate light units and biasing devices, allowing users to control power delivery and functionality through toggle switches, ensuring continuous operation of non-lighting functions during power interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If in-ceiling electronic devices are installed using traditional wiring methods, then the devices can be connected to power and function properly, but the installation requires professional assistance and is difficult to change or move after construction
Solution Approach 1:
The system divides the electronic device into separate functional modules that can be independently installed and positioned. The wireless communication module separates the control function from the power consumption function, allowing the device to be installed without complex wiring while maintaining full functionality. This segmentation enables retrofits in existing buildings without professional electrical work.
Solution Approach 2:
A wireless communication intermediary (such as Wi-Fi or Bluetooth module) is introduced between the power source and the electronic device. This intermediary allows the device to receive power wirelessly or through simple power harvesting, eliminating the need for traditional electrical wiring and enabling easy installation and relocation without professional assistance.
2Ease of manufacture
If electronic devices are installed during construction to ensure proper wiring and mounting, then the installation is more straightforward, but the devices cannot be easily moved or repositioned after the building is completed
Solution Approach 1:
The system transitions from a static, wired installation to a dynamic, wireless configuration. The electronic device can be freely repositioned and reinstalled at different locations without requiring structural modifications or professional electrical work, enabling adaptability to changing user needs while maintaining ease of installation through simple plug-and-play or wireless setup.
3Reliability
If traditional wired electronic devices are used, then continuous power supply is ensured, but the devices cannot operate during power interruptions and require professional installation
Solution Approach 1:
The system incorporates energy storage components (such as capacitors or small batteries) that are pre-charged to provide backup power during interruptions. This cushioning mechanism ensures continuous operation of critical functions during power outages while using simple, consumer-friendly installation methods that do not require professional electrical work.
Data Source
AI summary
Systems and methods for using light switches to control lighting and other functions are disclosed. Each switch may be a manual switch that is mounted to a wall. A biasing device may be positioned proximate each switch. When a user moves the switch out of a first position and into a second position or toward a second position, the delivery of household power to one or more light units may be interrupted. However, when the user releases the switch, the biasing device may provide an immediate automatic return of the manual switch to the first position. The resulting short interruption in household power may be used as a signal for controlling operation of the one or more light units and/or other electronic devices installed at one or more lighting sites corresponding to the switch.
