Innovation Solution
A digital projector design incorporating a light providing module with asynchronously controlled light-emitting chip units, an image generating module that converts the projection beam into an image beam, and a projection lens module that projects the image beam to a predetermined position, all configured on the same optical path, enabling sequential control of image generation and projection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If light-emitting chip units are controlled asynchronously through timing control, then image generation efficiency is improved, but device complexity increases
Solution Approach 1:
The light providing module is divided into multiple independently controllable light-emitting chip units, each capable of being turned on asynchronously. This segmentation allows precise timing control of individual light sources to generate projection beams for different color channels or image regions at different times, improving image generation efficiency while managing complexity through modular design
Solution Approach 2:
The system implements dynamic timing control where the activation timing of light-emitting chip units is adjusted based on the sequential processing requirements of the image generating module. This dynamic control enables optimized light emission patterns that match the processing speed and requirements of downstream components, enhancing overall system productivity
2Reliability
If multiple modules are configured on the same optical path, then projection quality is improved, but device complexity increases
Solution Approach 1:
The light providing module, image generating module, optical component module, and projection lens module are merged into a single integrated optical path configuration. This merging ensures that light passes sequentially through all modules in a unified trajectory, maintaining optical coherence and improving projection quality while reducing the complexity associated with multiple separate optical paths
Solution Approach 2:
The optical path is designed as a universal transmission channel that serves multiple functions: carrying projection beams from light-emitting chips, transmitting image information through the image generating module, and delivering the final image beam to the projection lens. This multi-functional optical path reduces the need for separate dedicated paths for each module, simplifying the overall system configuration
