Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display devices face challenges in efficiently dissipating heat and achieving miniaturization due to the need for space to accommodate heat dissipators.
Innovation Solution
The image display device incorporates a metal circuit board with a stacked plate-shaped metal member and a reflective optical unit that efficiently dissipates heat by conducting heat generated by light-emitting elements to a connector mounted on the metal circuit board, allowing for miniaturization without additional heat dissipation fins.

Engineering Contradiction Analysis
1Temperature
If a heat dissipator is installed to dissipate heat from the circuit board, then heat dissipation efficiency is improved, but device size increases
Solution Approach 1:
The patent combines the heat dissipation function with the connector structure by integrating a heat dissipation fin into the connector housing. This allows the connector to serve dual purposes: electrical connection and heat dissipation, thereby improving heat dissipation efficiency without increasing overall device size
Solution Approach 2:
The connector is designed to perform multiple functions simultaneously: providing electrical connection between components and acting as a heat dissipation structure through its integrated fin. This multi-functionality eliminates the need for separate heat dissipation components, resolving the contradiction between heat dissipation performance and device compactness
