Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heat insulation structures for electronic apparatuses, such as projection display devices, are inadequate in effectively reducing the influence of heat sources on their surroundings, particularly in small devices where space and heat management are critical.
Innovation Solution
A heat insulation structure comprising a heat insulating member with an opening, surrounded by a shape retaining member that maintains the shape of the insulating member to efficiently encase a heat source, utilizing materials like aerogel for enhanced insulation and a metallic shape retaining member for reflective properties, allowing for effective heat management and compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a heat insulating member is provided to surround the heat source, then the influence of heat source on surroundings is reduced, but the device size increases and design flexibility decreases
Solution Approach 1:
The heat insulating member is formed as a thin-walled cylindrical shell structure that can be easily fitted around the heat source. This thin-walled structure provides effective heat insulation while occupying minimal space, thus maintaining design flexibility and allowing compact device layout without compromising thermal isolation performance
2Volume of moving object
If the heat insulating member thickness is reduced for compact design, then device size decreases, but heat insulation performance deteriorates
Solution Approach 1:
The heat insulating member is constructed from composite materials combining resin matrix with heat-insulating inorganic particles or aerogel. This composite structure achieves high heat insulation performance with thin wall thickness, allowing compact device design while effectively blocking heat transfer from the light source to surrounding components
3Object-affected harmful factors
If conventional heat insulating materials are used, then heat insulation is provided, but the insulating member cannot maintain stable shape and dimensions
Solution Approach 1:
The heat insulating member is designed as a rigid thin-walled cylindrical shell structure that inherently maintains its shape and dimensions. This shell structure provides mechanical support to keep the insulating material in a stable configuration, ensuring consistent thermal insulation performance and reliable positioning around the light source
