1Volume of moving object
If a subminiature camera module structure is used, then the camera module can be widely used in small electronic products and vehicles, but heat dissipation efficiency deteriorates
Solution Approach 1:
The patent introduces protrusions extending from the spacer in the radial direction to create additional heat dissipation surfaces. This dimensional extension allows heat to be dissipated more effectively from the inner region toward the outer region without increasing the overall camera module volume, thus resolving the contradiction between miniaturization and heat dissipation efficiency
Solution Approach 2:
The spacer is divided into multiple plate parts with protrusions at different radial positions. This segmentation creates multiple heat dissipation pathways and surfaces, allowing heat to be dissipated through various routes simultaneously, improving overall heat dissipation efficiency while maintaining the compact subminiature structure

If a complex housing structure with shield can and spacer is used, then heat dissipation efficiency is improved, but manufacturing complexity increases
Solution Approach 1:
The patent integrates the shield can and spacer into a unified housing structure where the spacer's protrusions directly contact the shield can. This merging reduces the number of separate components and assembly steps while maintaining effective heat dissipation pathways, thus improving heat dissipation without proportionally increasing manufacturing complexity
Solution Approach 2:
The spacer serves multiple functions: it provides structural support, creates heat dissipation pathways through its protrusions, and facilitates thermal contact between the shield can and heat generating components. This multi-functionality reduces the need for additional dedicated heat dissipation components, simplifying the overall manufacturing process
