Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting systems fail to combine a diffused light effect from a lighting bar with a concentrated, directed light effect, and are not suitable for outdoor use due to lack of protection against environmental factors.
Innovation Solution
A lighting system comprising a longitudinally extending bar body with a central opening, a linear electronic lighting board embedded in a translucent polymer insulating body, and independently powered lighting devices that can be mechanically and electrically connected to the bar, allowing for flexible positioning and high protection against outdoor elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a lighting bar with embedded linear electronic board is used, then the lighting bar provides diffused light effect and structural protection, but it cannot be combined with concentrated directed light devices
Solution Approach 1:
The lighting system is divided into separate functional modules: a lighting bar providing diffused illumination and independent lighting devices providing concentrated directed light. This segmentation allows each module to perform its specific function optimally while maintaining system versatility.
Solution Approach 2:
The lighting bar is designed with dual functionality: it provides diffused light through its linear electronic board while simultaneously serving as a mounting structure and power supply for additional concentrated lighting devices, creating a multi-functional universal lighting platform.
2Adaptability or versatility
If lighting devices are added to the lighting bar, then concentrated directed light is achieved, but the structural integrity and protection degree are compromised
Solution Approach 1:
Lighting devices are nested within or mounted on the lighting bar structure, with connection needles passing through the insulating body to access the electronic board. This nesting approach allows integration while maintaining the protective enclosure.
Solution Approach 2:
Connection needles serve as intermediaries, penetrating the insulating body to establish electrical contact between external lighting devices and the internal electronic board, enabling integration without compromising the protective barrier.
3Reliability
If the lighting bar is designed for outdoor use with high protection, then environmental resistance is improved, but flexible positioning of lighting devices is limited
Solution Approach 1:
The lighting bar functions as both a protected lighting source and a universal mounting platform with standardized connection points, allowing various lighting devices to be positioned flexibly along its length while maintaining outdoor protection integrity.
Solution Approach 2:
The system allows dynamic configuration of lighting devices at different positions along the lighting bar, enabling flexible positioning and arrangement adaptation while the protective structure remains static and intact.
4Ease of operation
If electrical connection needles pass through the insulating body, then power supply to lighting devices is enabled, but the protection degree is reduced
Solution Approach 1:
Connection needles act as controlled intermediaries that penetrate the insulating body at specific locations to establish electrical contact, enabling power transmission while minimizing impact on overall protection through precise and limited penetration points.
Solution Approach 2:
The insulating body functions as a flexible protective shell that can accommodate controlled penetrations for electrical connections while maintaining its overall protective function, similar to how flexible membranes allow selective passage while providing barrier protection.
