Projector Cooling Target Segmentation for Compact Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projectors with integrated heat sinks tend to have large exterior housings due to the placement of the heat sink inside the cover member, which increases the projector's size and complexity.
Innovation Solution
A projector design where the cooling target, such as a wireless communication device, is separably attached to the exterior housing and forms a channel with a channel forming member, allowing a cooling gas to flow along the device for efficient cooling, reducing the need for a large internal heat sink and thus minimizing the projector's size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the heat sink is integrated inside the cover member, then the cooling function is improved, but the projector size increases
Solution Approach 1:
The cooling system is segmented into separate components: the cover member and the heat sink are detachably connected rather than integrated. This allows the heat sink to be separated from the main projector body, reducing the projector's volume while maintaining the cooling function through the detachable connection that enables airflow passage between the light source device and heat sink.
Solution Approach 2:
The heat sink is extracted from the interior of the cover member and positioned externally or in a separate location. The cover member includes a through hole that allows air to pass through to the heat sink, which is connected detachably. This extraction reduces the space required within the projector housing while preserving the cooling capability.
2Ease of operation
If the cover member projects to the lower surface side, then the cooling target can be accessed, but the projector becomes larger
Solution Approach 1:
The cover member is segmented with a through hole that provides access to the cooling target without requiring the entire cover member to project outward. This allows selective access to the heat sink area while maintaining a compact overall projector structure.
Solution Approach 2:
Instead of projecting the cover member in one dimension (lower surface side), the design uses a detachable connection system that allows access and cooling in a different spatial arrangement. The heat sink can be connected and accessed through the through hole without requiring extensive projection of the cover member, effectively utilizing alternative spatial dimensions.

Data Source
AI summary
A projector that modulates and projects light emitted from a light source includes an exterior housing configuring the exterior of the projector, a cooling target separably attached from the outside of the exterior housing, a cooling fan configured to deliver a cooling gas to the cooling target, and a channel forming member forming a part of a channel in which the cooling gas delivered from the cooling fan flows. In a state in which the cooling target is attached to the projector, the cooling target and the channel forming member form the channel. The cooling gas flows in the channel along the cooling target.
