Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety lighting systems require multiple interchangeable optics, leading to potential damage to light-emitting diodes, mechanical stress, and increased storage and organizational efforts due to the need for various components, which complicates installation and ecological sustainability.
Innovation Solution
A lighting arrangement with a lens arrangement that includes multiple optical elements, which can be displaced or rotated relative to the light-emitting diode arrangement, eliminating the need for separate components and ensuring proper alignment and protection during assembly, using guide means and latching mechanisms to secure the optical elements over the diodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple interchangeable optics are used to adapt lighting to different functions, then adaptability is improved, but device complexity and storage requirements increase
Solution Approach 1:
The patent implements a single lighting module that can perform multiple lighting functions (escape route lighting, anti-panic lighting, workstation lighting) by integrating multiple optical elements (lenses with different beam angles) into one unit. The module can be configured for different functions by rotating the lens assembly to position different optical elements over the LED, eliminating the need for multiple separate lighting devices or interchangeable component storage.
2Ease of operation
If optics are attached by reversible attachment devices, then ease of operation is improved, but reliability deteriorates due to risk of LED damage
Solution Approach 1:
The patent employs a nested structure where the optical elements (lenses) are positioned within a housing that rotates over the LED. The lens assembly is contained within a protective structure that guides its movement, ensuring that lenses are lowered onto LEDs in a controlled manner rather than being directly attached. This nested arrangement protects the LED from direct mechanical contact during optics replacement while maintaining ease of operation through rotational configuration changes.
3Adaptability or versatility
If optics are replaced frequently, then adaptability is improved, but loss of time increases due to installation complexity
Solution Approach 1:
The patent implements a dynamic configuration system where the lens assembly can be rotated to different positions to change lighting functions. Instead of requiring complete disassembly and reassembly of multiple separate components, the system allows rapid reconfiguration by simply rotating the integrated lens assembly to position different optical elements over the LED, significantly reducing the time required to adapt lighting for different functions.
