Imaging Device Elastic Member and Plate for Dust Shielding and Thermal Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging apparatuses face challenges in effectively shielding against dust and light while also efficiently dissipating heat, as they often compromise on either dust-proofing or thermal management.
Innovation Solution
The proposed imaging apparatus incorporates an imaging optical system, a holding member, an imaging device, an elastic member, and a plate-like member, where the elastic member surrounds the light-receiving region with a ring-shaped contact and the plate-like member overlaps the elastic member, enhancing dust shielding and thermal dissipation by promoting heat diffusion through higher thermal conductivity materials.

1Object-affected harmful factors
If a dust-proofing and light-shielding member is used to shield the imaging device, then dust and light entry is prevented, but heat dissipation is compromised
Solution Approach 1:
The shielding structure is divided into multiple segments: a dust-proofing and light-shielding member for dust and light protection, and a separate heat dissipation member with higher thermal conductivity for thermal management. This segmentation allows each component to optimize its specific function without compromising the other.
Solution Approach 2:
The holding member serves as an intermediary structure that integrates both the dust-proofing/light-shielding function and the heat dissipation function. It holds the imaging optical system while providing a thermal conduction path from the imaging device to the heat dissipation member, mediating between the shielding requirements and thermal management needs.
2Manufacturing precision
If the elastic member is positioned to surround the light-receiving region, then precise positioning and protection are achieved, but the structure becomes more complex
Solution Approach 1:
The elastic member is designed to perform multiple functions simultaneously: it provides precise positioning of the imaging device, surrounds and protects the light-receiving region, and maintains contact for thermal conduction. This multi-functionality reduces the need for separate components, thereby reducing overall structural complexity while achieving precise positioning.
3Temperature
If the plate-like member overlaps the elastic member, then thermal dissipation is enhanced, but the device dimensions increase
Solution Approach 1:
The plate-like member is positioned in a different spatial dimension (overlapping in the optical axial direction) rather than extending the device footprint in the lateral direction. This dimensional arrangement enhances thermal dissipation through increased contact area with the elastic member and imaging device while minimizing the increase in overall device area.
