Solution Overview
Problem
Existing mobile devices face limitations in image sensor resolution and lens performance due to space constraints, and dedicated cameras are bulky and lack wireless image transfer capabilities.
Innovation Solution
A mobile device with a module holder featuring a recess with a circular arc and secant contour for a detachable camera module, ensuring a twist-proof and stable mechanical connection, and an electrical interface for signal transmission, using spring-loaded locking and contact elements to facilitate easy attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the camera module is disposed to protrude from the mobile device, then the camera lens can be positioned at the light incident surface for optimal imaging, but the design space for arranging other components (flash, microphone, sensor) is reduced
Solution Approach 1:
The patent embeds the flash, microphone, and sensor within the camera module housing, nesting multiple components inside the protruding structure. This allows the camera lens to protrude for optimal imaging while other components are accommodated within the module's internal space, resolving the conflict between imaging performance and component arrangement.
2Manufacturing precision
If the camera module protrudes from the mobile device, then optimal camera positioning is achieved, but the aesthetic appearance and compactness of the device are compromised
Solution Approach 1:
The patent positions the camera module on the side surface of the mobile device rather than the front or back face, utilizing the side dimension for camera protrusion. This dimensional change allows optimal camera positioning while maintaining the front and back surfaces as flat, aesthetically pleasing planes, thus resolving the contradiction between positioning accuracy and device compactness.
3Quantity of substance
If multiple components are integrated into the camera module, then space efficiency is improved, but the heat generation and interference between components increases
Solution Approach 1:
The patent divides the camera module into distinct functional regions: a first region for the flash and a second region for the microphone and sensor, with each component having its dedicated space. This segmentation reduces heat accumulation and electromagnetic interference between components while maintaining high integration density within the compact module structure.
