Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting fixtures have fixed luminescent characteristics, making them poorly adaptable to varying climate conditions, which requires multiple designs for different environments, increasing manufacturing costs and failing to adjust to changing conditions.
Innovation Solution
A light source module with a tunable-focal length lens and a controller that adjusts the lens's characteristics by changing voltage states, allowing the light beam to adapt to different environments by altering its shape, color temperature, and optical path length, utilizing a liquid state or liquid crystal tunable-focal length lens and an environmental parameter sensor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If lighting fixtures have fixed luminescent characteristics, then manufacturing cost is reduced and device complexity is lowered, but adaptability to different environmental conditions deteriorates
Solution Approach 1:
The patent applies the dynamics principle by replacing the fixed focal length lens with a tunable-focal-length lens that can dynamically adjust its focal length based on environmental conditions. The lens focal length changes from a static parameter to a dynamic one controlled by the controller, enabling the lighting fixture to adapt its optical characteristics to different environments without requiring multiple fixed designs.
Solution Approach 2:
The patent implements parameter changes by modifying the focal length parameter of the lens through voltage control. The controller adjusts the focal length parameter of the tunable-focal-length lens according to detected environmental conditions (such as moisture concentration), thereby changing the optical behavior of the light beam to suit different climate conditions while using a single fixture design.
2Adaptability or versatility
If multiple lighting fixture designs are created for different environments, then adaptability to different climates is improved, but manufacturing cost increases
Solution Approach 1:
The patent applies universality by designing a single lighting fixture that can perform multiple optical functions through the tunable-focal-length lens. Instead of manufacturing separate fixtures for different environments, one universal fixture design with adjustable focal length can serve multiple environmental conditions, reducing manufacturing complexity and cost while maintaining adaptability.
Solution Approach 2:
The dynamic adjustment capability of the tunable-focal-length lens allows a single fixture design to replace multiple static designs, enabling one product to serve multiple market segments and environmental conditions without requiring separate manufacturing lines for each variant.
3Manufacturing precision
If lighting fixtures are designed for specific areas with specific optical parameters, then optical performance in that environment is optimized, but adaptability to changing climate conditions deteriorates
Solution Approach 1:
The patent resolves this contradiction by making the optical parameters dynamic rather than static. The tunable-focal-length lens allows the lighting fixture to maintain precise optical performance across different environments by adjusting its focal length in real-time, rather than being locked into a single optimized parameter set for one specific condition.
Solution Approach 2:
The patent implements feedback by using an environmental sensor (such as a moisture sensor) to detect current environmental conditions and feed this information to the controller, which then adjusts the focal length of the lens accordingly. This closed-loop control system ensures the lighting fixture continuously adapts to changing climate conditions while maintaining optimal optical performance.
