Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional camera motor designs are limited in height, making them unsuitable for the thin and light design requirements of modern mobile phones and electronic devices.
Innovation Solution
A camera motor design featuring a base with a recessed bottom surface forming a receiving slot, a carrying member to move a lens along an optical axis, and a drive member connected to the carrying member to facilitate automatic focus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If conventional motor design is used, then the camera module can achieve automatic focus function, but the height of the camera module becomes too large for thin and light electronic products
Solution Approach 1:
The patent applies nesting by placing the image sensor and light filter module inside the receiving slot of the base, effectively hiding these components within the motor structure. This nested arrangement reduces the overall height of the camera module while maintaining the ability to integrate larger sensors and filters, directly resolving the contradiction between compact height and component integration capability.
Solution Approach 2:
The patent transitions from a conventional vertical stacking arrangement to a horizontal integration approach by creating a receiving slot that extends along the height direction. This dimensional reorganization allows components to be arranged horizontally within the slot rather than vertically stacked, reducing the height dimension while maintaining component integration.
2Length of moving object
If the height of camera module is reduced, then thin and light design requirement is met, but the space for image sensor and light filter module becomes limited
Solution Approach 1:
The receiving slot acts as a nested space within the base structure, creating an internal cavity that accommodates the image sensor and light filter module. This nesting approach effectively utilizes the height direction for spatial organization without increasing the overall height of the camera module, thereby providing adequate space for sensors while maintaining a compact form factor.
Solution Approach 2:
The base is segmented into different functional regions, including the receiving slot that specifically accommodates the image sensor and light filter module. This segmentation allows for optimized space utilization within the height-constrained structure, separating the motor components from the optical components while maintaining compact overall dimensions.
