Imaging Apparatus Vertical FPC Cable Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing assembly method for sensor shift optical image stabilization (OIS) lens modules faces challenges due to the insufficient rigidity of flexible printed circuit (FPC) cables, which can cause bending and contact with other components, leading to soldering failures and assembly issues.
Innovation Solution
The proposed solution involves an imaging apparatus with a movable substrate, image sensing chip, and a bearing frame, where the flexible flat cable's electrical connection end is disposed perpendicular to the substrate, avoiding contact with other components, and signal feed-in contacts facilitate active alignment and enabling the image sensing chip, improving the assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the FPC cable is bent horizontally and soldered to the image sensor substrate, then the cable can be connected to transmit signals, but the cable lacks sufficient rigidity and may swing or touch other components causing soldering failure
Solution Approach 1:
The patent changes the orientation of the FPC cable from horizontal to vertical arrangement. The cable extends perpendicular to the image sensor substrate surface, connecting to the lens assembly above rather than alongside other components. This dimensional change eliminates interference with horizontally arranged components and provides adequate space for soldering operations.
2Adaptability or versatility
If the FPC cable is arranged horizontally, then it can connect components, but it cannot maintain its shape and is likely to swing affecting assembly
Solution Approach 1:
The FPC cable is repositioned from a horizontal plane to a vertical orientation, extending upward from the image sensor substrate to connect with the lens assembly. This vertical arrangement provides natural structural support and prevents the cable from swinging or deforming during the assembly process.
3Ease of manufacture
If the horizontally bent part of the FPC cable is placed near other components, then connection is achieved, but it touches other components and cannot be placed successfully
Solution Approach 1:
The cable connection path is changed from a horizontal route that intersects with other components to a vertical route that extends upward away from the component plane. This allows successful placement of all components without interference, as the vertical cable path occupies a different spatial dimension.
