Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera systems face challenges in integrating high-resolution capabilities within a compact form factor, leading to unsatisfactory aesthetics and thermal management issues due to the complexity of assembly and heat dissipation in smaller housings.
Innovation Solution
A cylindrical housing made of aluminum, with a subassembly that includes a camera module and processing resources, is used, where a bezel and rear cover provide a secure assembly, and a graphene sheet acts as a thermal barrier to reduce heat transfer, maintaining an aesthetically pleasing and functional design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a compact form factor is used for the camera housing, then the device size is reduced, but thermal management becomes difficult and assembly complexity increases
Solution Approach 1:
A graphene thermal barrier sheet is introduced as an intermediary layer between the camera module and the housing interior. This thermal barrier prevents direct heat transfer to the housing, allowing the compact housing to maintain aesthetic appearance without compromising thermal management of the camera module.
Solution Approach 2:
A thin graphene sheet is used as a flexible thermal barrier that can be applied within the compact housing space. This thin film provides effective thermal insulation without adding significant volume, enabling heat management in the constrained space of a compact camera housing.
2Volume of moving object
If a compact form factor is used for the camera housing, then the device size is reduced, but assembly complexity and aesthetic appearance deteriorate due to exposed components
Solution Approach 1:
The camera module is integrated with the housing structure through a unified mounting mechanism. The housing interior is designed to directly receive and secure the camera module, eliminating the need for separate brackets or complex assembly steps, thus reducing overall assembly complexity while maintaining compact size.
3Measurement precision
If high resolution camera module is integrated, then image quality is improved, but thermal heat generation increases
Solution Approach 1:
The graphene thermal barrier sheet serves as a mediator between the high-resolution camera module and the housing. It blocks thermal heat generated by the high-resolution sensor from transferring to the housing, allowing image quality improvement without proportionally increasing thermal issues in the compact housing.

AI summary
An information handling system peripheral camera is built by inserting a subassembly into a cylindrical housing and enclosing the subassembly with a bezel at the front and cover at the rear. The cylindrical housing is extruded with aluminum to have seams formed along the length of the interior. The seams provide alignment of the subassembly and are machined at the front and rear to form threads that accept screws to couple the bezel and rear cover to the cylindrical housing. To hide the screws, a back plate couples over the rear cover and an opaque treatment is applied to a circumference of a cover glass placed over the bezel.
