Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cinematographic lighting devices require separate 'soft' and 'hard' light projection devices, increasing costs and transport complexity due to lack of modular adaptability.
Innovation Solution
A single device with two panels of LED sources, one with collimators for 'hard' light and one with open sections for 'soft' light, combined with a modular frame for adaptable projections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If separate soft light and hard light projection devices are used, then each device can provide specialized projection quality, but production costs and transport complexity increase
Solution Approach 1:
The patent combines both soft light and hard light projection devices into a single integrated device. The first panel with collimating devices and the second panel without collimating devices are mounted on the same frame, allowing both projection types to be achieved in one device, thereby reducing the total number of devices needed while maintaining specialized projection qualities
Solution Approach 2:
The integrated projection device achieves multi-functionality by incorporating both soft light and hard light projection capabilities. The device can selectively activate different LED panels or combinations thereof to provide either soft light diffusion or hard light concentration, making it a universal solution that replaces multiple specialized devices
2Adaptability or versatility
If multiple separate projection devices are distributed to various locations, then location-specific requirements can be met, but transport costs and logistics complexity increase
Solution Approach 1:
By merging soft light and hard light projection devices into a single unit, the patent reduces the quantity of devices that need to be transported and distributed to various locations. The integrated device can be moved as one unit while still providing location-specific projection requirements through selective panel activation
3Device complexity
If fixed non-modular projection devices are used, then device structure is simple, but operating capacity cannot be increased through modular mounting
Solution Approach 1:
The patent applies segmentation by dividing the projection device into separate panels (first panel with collimating devices, second panel without collimating devices) that can be independently controlled. This modular panel structure allows selective activation of different panels to adjust operating capacity and projection coverage without increasing overall structural complexity
Solution Approach 2:
The device incorporates dynamic control capabilities through the control unit that can selectively activate different LED panels or combinations thereof. This dynamic activation allows the operating capacity to be adjusted based on production requirements, transforming a static device into one with adaptable performance levels
