Auxiliary Portable Photographing Device for Mobile Phones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current smartphones, despite advanced photography capabilities, are limited by their size and weight, making them less convenient and capable compared to professional cameras, which are bulkier and heavier due to their comprehensive hardware configurations.
Innovation Solution
An auxiliary portable photographing device for smartphones is developed, comprising a detachable image collection module with a multistage barrel lens system, CMOS imaging unit, and data transmission module, connected via a USB interface, allowing for enhanced image capture and processing while simplifying storage and processing systems, and featuring a supercapacitor power module for efficient power management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If professional cameras with comprehensive hardware configurations (body, image collection module, AD conversion module, data storage module, data transmission module, data processing module, image display module) are used, then image quality and photographing capability are improved, but volume and weight increase making them inconvenient to carry
Solution Approach 1:
The patent divides the professional camera system into separate functional modules: an image collection module (lens, sensor, controller) that can be detached, and a mobile phone that provides power, storage, and processing. This segmentation allows the heavy components to be distributed, making the portable device lightweight while maintaining professional-grade photographing capability when modules are connected.
Solution Approach 2:
The mobile phone serves multiple functions: it acts as the body housing, provides power through its battery, stores image data, processes images, and displays results. The detachable image collection module can be used with different phones, creating a universal system that eliminates the need for a dedicated camera body, thereby reducing weight.
2Reliability
If professional cameras with comprehensive hardware configurations are used, then image quality and photographing capability are improved, but volume increases making them inconvenient to carry
Solution Approach 1:
By segmenting the camera system into a compact image collection module and utilizing the mobile phone's existing structure for housing, storage, and processing, the overall volume is reduced. The image collection module contains only essential components (lens, sensor, controller) while the phone provides the remaining functions in its existing form factor.
Solution Approach 2:
The patent merges the mobile phone with the image collection module to create an integrated photographing system. The phone's screen serves as the image display, its processor handles image processing, and its battery provides power, eliminating the need for separate housing, display, and power supply components that would increase volume.
3Ease of operation
If smartphones use built-in cameras for photographing, then portability is maintained, but image quality cannot reach the level of professional cameras
Solution Approach 1:
The system dynamically adapts between two modes: using the smartphone's built-in camera for casual portability, or attaching the professional image collection module when high-quality images are needed. This dynamic configuration allows the system to optimize between portability and image quality based on the specific situation.
Solution Approach 2:
The detachable image collection module acts as an intermediary between the mobile phone and professional camera systems. It provides professional-grade image collection capabilities while maintaining compatibility with the phone's interface, power, and data systems, thereby bridging the gap between portability and image quality.
