Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional projectors require a large size due to the horizontal arrangement of components, which hampers heat dissipation airflow and leads to inefficient heat management and potential component failure from high temperatures.
Innovation Solution
The projector design includes a casing with overlapping light source and light valve modules at different horizontal planes, along with strategically positioned air inlets and outlets to enhance heat dissipation airflow, allowing for improved heat management and reduced size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If components are arranged horizontally at the same level to reduce complexity, then device complexity is reduced, but the projector size increases and heat dissipation efficiency deteriorates
Solution Approach 1:
The patent transitions from a two-dimensional horizontal arrangement of components to a three-dimensional overlapping configuration. The light source module and light valve module are positioned at different horizontal planes, with the light source module above the light valve module, utilizing the vertical dimension to reduce the overall footprint of the projector while maintaining functional separation and improving heat dissipation pathways.
2Volume of stationary object
If components are compacted to reduce projector size, then volume is reduced, but heat dissipation efficiency deteriorates and components may fail due to overheating
Solution Approach 1:
The patent segments the heat dissipation system into multiple independent pathways. One pathway draws air through the light source module via a first air inlet, while another pathway draws air through the light valve module via a second air inlet. This segmentation allows each component to have dedicated cooling airflow, preventing heat accumulation and improving component reliability in the compact design.
3Ease of manufacture
If components are arranged horizontally at the same level, then ease of manufacture is improved, but heat dissipation efficiency deteriorates
Solution Approach 1:
The patent positions the light source module and light valve module at different horizontal planes, creating vertical separation that enables independent heat dissipation pathways. This three-dimensional arrangement allows airflow to pass through each module separately, significantly improving heat dissipation efficiency while maintaining manufacturing feasibility through standardized module designs.
4Device complexity
If a single air inlet is used for heat dissipation, then device complexity is reduced, but heat dissipation efficiency deteriorates due to insufficient airflow through all components
Solution Approach 1:
The patent divides the air inlet system into multiple segments: a first air inlet positioned to draw air through the light source module, and a second air inlet positioned to draw air through the light valve module. This segmentation ensures that each heat-generating component receives adequate cooling airflow, maximizing heat dissipation efficiency while maintaining relatively simple overall system architecture.
