Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional optical systems are used in electronic devices, then the basic photography function is achieved, but the device thickness and complexity increase
Solution Approach 1:
The optical system is divided into multiple independent modules, each with specific functions. The first module includes a first optical member for image capture, while the second module includes a second optical member for additional optical functions. This segmentation allows each module to be optimized independently, reducing overall system complexity while maintaining compact size.
Solution Approach 2:
The patent implements a nested structure where the first movable portion and first fixed portion are integrated within the first module, and the second optical member is positioned within the second module. The modules are arranged in a nested configuration along the light path, allowing multiple optical functions to be achieved within a compact volume without increasing device thickness.
2Reliability
If light path adjustment is implemented for image stabilization, then image quality improves, but the structural complexity increases
Solution Approach 1:
The first movable portion is designed to dynamically adjust the light path in response to detected motion or focus requirements. The movable portion can shift position along the light axis to compensate for hand shake or to achieve focus at different depths, providing image stabilization and autofocus capabilities through dynamic adjustment rather than fixed structure.
Solution Approach 2:
The first movable portion acts as an intermediary element between the incoming light and the image sensor. By positioning this movable portion at a strategic location in the light path, it can effectively stabilize the image without requiring complex stabilization mechanisms throughout the entire optical system, thereby reducing overall structural complexity.
3Adaptability or versatility
If multiple optical members are added for zooming and focusing, then functionality improves, but the assembly difficulty increases
Solution Approach 1:
The optical system is segmented into functional modules: the first module contains the first optical member for primary image capture, and the second module contains the second optical member for additional optical functions. Each module can be assembled and tested independently before integration, significantly easing the manufacturing and assembly process while maintaining zooming and focusing capabilities.
Solution Approach 2:
The second optical member is designed to serve multiple functions including zooming, focusing, and potentially optical image stabilization. By making this single component multi-functional rather than adding separate dedicated components for each function, the patent reduces the total number of parts and simplifies the assembly process while maintaining versatility.
