Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video-recording devices with multiple lenses face challenges in achieving accurate image quality due to difficulties in calibrating the optical axis with a CMOS active pixel sensor during assembly, and managing the complex composition of components, particularly when incorporating multiple auto-focus lenses.
Innovation Solution
An optical image capturing module with an integrally manufactured multi-lens frame that embeds signal transmission elements, ensuring the optical axis of each auto-focus lens assembly overlaps with the central normal line of the sensing surface, and using a circuit assembly with image sensor elements and driving assemblies to maintain image quality and prevent component deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple lenses are included to meet higher photographic requirements, then the imaging capability is improved, but the assembly complexity and difficulty of calibrating optical axis increase
Solution Approach 1:
The patent combines multiple lens assemblies with their supporting structures into a single integrally manufactured multi-lens frame. This merging approach reduces the number of separate components that need to be assembled and calibrated, directly addressing the assembly complexity issue while maintaining the ability to capture multiple images simultaneously.
Solution Approach 2:
The multi-lens frame serves multiple functions: it provides structural support for multiple lens assemblies, defines the optical axes for each lens, and integrates signal transmission elements. This multi-functionality reduces the overall system complexity by eliminating the need for separate mounting structures and calibration mechanisms.
2Adaptability or versatility
If multiple lenses are assembled to improve imaging quality, then the photographic performance is enhanced, but the manufacturing precision requirements increase due to calibration difficulties
Solution Approach 1:
The optical axes for each lens assembly are predetermined and integrated into the multi-lens frame structure during manufacturing. This preliminary establishment of optical axes eliminates the need for post-manufacturing calibration, ensuring precise alignment without increasing manufacturing precision requirements during the assembly process.
Solution Approach 2:
The multi-lens frame self-defines the optical axes through its integral structure, eliminating the need for external calibration equipment or processes. The frame's geometry inherently ensures that each lens assembly is correctly positioned, making the system self-aligning rather than requiring precision calibration.
3Ease of manufacture
If signal transmission elements are externally connected to avoid embedding, then the assembly process is simpler, but component deformation and short-circuiting risks increase during packing
Solution Approach 1:
The signal transmission elements are embedded within the multi-lens frame structure, nesting the electrical connections inside the mechanical support structure. This protection prevents external damage, deformation, and short-circuiting during packing and handling, while the integrated design maintains assembly simplicity through a single manufacturing process.
