Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in mobile devices such as smartphones is the need to reduce the number of cameras without sacrificing photography and videography functionality, as each additional camera increases size, weight, and cost, which is also applicable to other systems like drones and vehicles.
Innovation Solution
Integrating two cameras with different fields of view into one camera module, utilizing optical axis bending and a periscope format with a turning mirror or prism to switch between fields of view, allowing for a smaller and/or cheaper imaging optical system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple cameras are used to achieve different fields of view, then photography and videography functionality is improved, but device size, weight, and cost increase
Solution Approach 1:
The patent combines multiple camera systems with different fields of view into a single integrated camera module. The system uses a first camera for a first field of view and a second camera for a second field of view, merging their functions into one unified structure that shares common components such as the imaging element, reducing overall device weight while maintaining multi-FOV capability
Solution Approach 2:
The single camera module is designed to perform multiple functions by capturing images at different fields of view using both the first and second cameras. The imaging element and associated processing circuitry universally handle data from both camera systems, enabling the device to function as both a wide-angle and telephoto camera without requiring separate dedicated hardware for each function
2Adaptability or versatility
If multiple cameras are used to achieve different fields of view, then photography and videography functionality is improved, but device size increases
Solution Approach 1:
The patent implements a nested configuration where the second camera is positioned within or adjacent to the first camera's optical path structure. The imaging element serves both camera systems, and the optical components are arranged in a compact, space-efficient manner that allows one camera system to be effectively nested within the overall structure of the other, minimizing the total volume occupied
Solution Approach 2:
By merging the optical paths and sharing common components such as the imaging element, focus actuator, and housing structure, the patent reduces the overall volume required to accommodate what would traditionally be two separate camera modules. The integrated design eliminates redundant structures and optimizes space utilization
3Adaptability or versatility
If multiple cameras are used to achieve different fields of view, then photography and videography functionality is improved, but manufacturing cost increases
Solution Approach 1:
The patent reduces manufacturing cost by merging multiple camera systems into a single integrated module that shares common components. The imaging element, focus actuator, housing, and control circuitry are shared between the first and second camera systems, reducing the total number of parts that need to be manufactured, assembled, and quality-tested, thereby lowering overall manufacturing cost
4Weight of moving object
If the number of cameras is reduced, then device size and cost are reduced, but photography and videography functionality is sacrificed
Solution Approach 1:
The single integrated camera module achieves multi-functionality by incorporating both a first camera for a first field of view and a second camera for a second field of view. The imaging element and processing circuitry universally handle data from both camera systems, enabling the device to perform both wide-angle and telephoto photography functions without requiring multiple separate camera modules
