Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emergency light systems require additional installation and equipment, resulting in unnecessary costs, time, and effort, as they can only operate while connected to a continuous power supply.
Innovation Solution
An electric lamp apparatus with an integrated emergency light module that utilizes a battery to power the lamp during power shutdowns, featuring a shutdown sensor, pulse generator, rectifier, filter, level sensor, booster, and switches to automatically switch between commercial power and battery power, eliminating the need for separate installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an emergency light is installed as separate equipment, then emergency lighting function is provided, but installation cost, time and effort increase
Solution Approach 1:
The patent combines the emergency light function with the ordinary electric lamp by integrating a battery and control circuit into the lamp structure. The lamp body houses both the main lighting components and emergency lighting components, allowing dual functionality from a single device. This merging eliminates the need for separate emergency light installation while providing reliable emergency lighting when power fails.
Solution Approach 2:
The electric lamp is designed to perform multiple functions: normal lighting when power is available and emergency lighting when power fails. The lamp body, battery, and control system work together to enable the same device to serve as both an ordinary light and an emergency light, maximizing utility while minimizing installation complexity.
2Productivity
If commercial power is used continuously, then lighting operation is maintained, but no emergency capability exists
Solution Approach 1:
The battery is continuously charged from the commercial power supply during normal operation, storing energy in advance for emergency use. The control circuit monitors power availability and maintains the battery in a charged state, so that when power fails, the emergency lighting function is immediately activated without delay. This preliminary charging action ensures both continuous lighting and emergency capability.
Solution Approach 2:
The control circuit continuously monitors the power supply status and provides feedback control. When commercial power is available, it directs power to charge the battery and operate the lamp. When power fails, the circuit detects the failure and automatically switches to battery power, maintaining lighting operation and providing emergency capability through this closed-loop feedback mechanism.
