Solution Overview
Problem
Existing lighting devices face challenges with heat dissipation, leading to thermal degradation of light source units and reduced performance.
Innovation Solution
A function module with a heat dissipator having an uneven shape on its second surface, thermally coupled to the illuminator, which increases the surface area for improved heat dissipation and includes a gap between the heat dissipator and the operation housing to facilitate heat release, along with elastic bodies to absorb impact and enhance portability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a conventional flat heat dissipator is used, then the structure is simple, but the heat dissipation efficiency is insufficient
Solution Approach 1:
The heat dissipator surface is transformed from a flat two-dimensional plane to a three-dimensional uneven surface with protrusions and recesses. This dimensional change increases the effective surface area available for heat dissipation without significantly increasing the overall device volume, thereby improving heat transfer efficiency while maintaining structural compactness.
Solution Approach 2:
The heat dissipator surface is segmented into multiple protrusions and recesses rather than remaining as a single flat plane. This segmentation creates numerous localized heat dissipation zones that can operate independently, increasing the total heat dissipation area and improving thermal management efficiency.
2Adaptability or versatility
If the function housing is made rotatable for improved portability, then the module becomes more versatile, but the structural complexity increases
Solution Approach 1:
The function housing is designed with rotational capability around a first rotation axis, transforming from a static structure to a dynamic one. This allows the housing to be rotated between a closed position (for compact storage and portability) and an open position (for operation), providing adaptability while maintaining a relatively simple hinge-based mechanical structure.
