Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices, such as smartphones, lack the optical zoom function and adjustable aperture, making it difficult to capture clear images in various lighting conditions due to their compact and complex structure.
Innovation Solution
A camera module with a lens module that moves along its axis to adjust the distance with an optical element, coupled with a light shielding component that adjusts its opening size through a connecting structure, allowing for optical zoom and aperture control to optimize light entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If SLR cameras use optical zoom by moving the lens, then the optical zoom function is achieved, but the device becomes large in size and complex in structure
Solution Approach 1:
The patent combines the optical zoom function with a mobile phone camera module by integrating a movable lens module that can change focal length, merging the complexity of SLR optical zoom into a compact mobile device structure
Solution Approach 2:
The lens module is designed to be movable along the optical axis, allowing dynamic adjustment of focal length for optical zoom, while the light shielding component dynamically adjusts aperture size based on shooting requirements
2Adaptability or versatility
If the aperture size is fixed in miniaturized devices, then the device structure is simple, but the device cannot adapt to various shooting environments
Solution Approach 1:
The light shielding component is designed with adjustable opening size that can be dynamically changed by the lens module's movement, allowing the aperture to adapt to different lighting conditions and shooting environments
Solution Approach 2:
The light shielding component serves multiple functions: it acts as both a structural element and an adjustable aperture mechanism, allowing the same component to control light entry while maintaining structural integrity
